The final +command should print nothing, which means the example starts with a clean worktree. You do not need to configure a Git +remote. + +PowerContext isolates data by scope. The Codex plugin first uses an explicit scope or a bound Workstream. Otherwise, +it uses the normalized Git remote and finally falls back to the project path. Start every Codex session in the rest of +this tutorial from this **same directory**. + +## 5. Save Memory in the first Codex session + +Make sure the Server is still running in Terminal A, then start Codex from the example project: + +```bash +codex ``` -Every line from both commands should report `ok`. The first checks the package and Server; the second checks only the -optional Codex integration.

Before each request, the hook tries to recover relevant project context and independently captures +the current prompt as Source evidence. If the Server is unavailable, the hook fails open and does not block ordinary +Codex work. -## 3. Save project Memory +First, ask Codex to confirm the directory without writing data: -Start a new Codex session in a project directory. If Codex asks whether to trust the PowerContext hook, open `/hooks` -and approve it. +> Inspect the current project directory and Git status. Report only what you observe; do not modify files or write to +> PowerContext. + +After Codex reports the `README.md`, explicitly ask it to save three Memory entries: + +> Use PowerContext to save three separate project Memory entries: +> +> 1. decision: the parser uses the Python 3.11 standard-library `tomllib` module; +> 2. constraint: error messages must not contain secret values from the source configuration; +> 3. next-step: add malformed TOML input cases. +> +> After writing, list the active Memory and return the citation for each entry. Do not store secrets or credentials. + +This uses explicit `remember_memory` and does not need a generation model. Codex should first resolve one stable scope +for the current project, then write and list the three active entries in that same scope. + +**Success criteria:** Codex explicitly confirms all three successful writes and returns a citation for each Memory +entry. A citation identifies the exact entry and Revision. Codex reads the current entry before a later revision or +retirement and uses that exact citation as a concurrency check. + +## 6. Recover Memory in a second Codex session + +Exit the first Codex session, but leave the Server running in Terminal A. Confirm that Terminal B is still in the same +example project directory, then start Codex again: + +```bash +codex +``` + +This is a new session with none of the earlier chat history. Enter: + +> Use PowerContext to list all active Memory for the current project. Show the content, kind, and citation for each +> entry. Do not modify any entry. + +**Success criteria:** the new session lists the same three entries. This proves the data is in the project scope and +the Server's persistent database, rather than only in the first session's context window. + +If the list is empty, check these items in order: + +1. both Codex sessions were started from the same project directory; +2. `powercontext doctor` still reports `ok`; +3. `powercontext doctor codex` still sees an enabled plugin; +4. the current shell does not set a different `POWERCONTEXT_CODEX_SCOPE_ID`. + +## 7. Revise and retire Memory + +In the second Codex session, enter: + +> First read the exact citation for the current Memory, then make two changes: +> +> 1. revise the next-step to “record the malformed TOML line number and a safe error summary”; +> 2. retire the constraint “error messages must not contain secret values from the source configuration” with the +> reason “replaced by the shared logging redaction policy”. +> +> Finally, list active Memory again and explain which old Revisions remain in history but are no longer active. + +A revision creates a new Revision, while retirement changes the entry's active state. Both preserve history instead +of silently overwriting or deleting an older record. + +**Success criteria:** the active list includes the revised next-step and no longer includes the retired constraint. +The original next-step Revision and retired constraint remain available when complete history is explicitly requested. + +## 8. Produce a state that can be handed off + +Ask the second Codex session to make one small, inspectable change to the example project: + +> Add a “Next test” section to README.md stating that malformed TOML should return the line number and a safe error +> summary. Do not create a Git commit. Then run `git diff --check` and report the changed files and check result. + +Confirm that Codex reports a modified `README.md` and a passing `git diff --check`. Then enter this one line: + +> Handoff this work. + +`Handoff this work` is explicit authorization to create one durable Handoff milestone. In the same turn, the +PowerContext `project-context` Skill: + +1. selects or confirms the current Workstream and scope; +2. inspects the objective, branch, worktree, changed files, and observed checks; +3. assembles blockers, omissions, and the next action; +4. prepares the Handoff; +5. commits it and returns an exact Revision. + +If more than one Workstream exists, Codex first presents a picker. Select the actual project instead of allowing the +agent to guess silently. + +**Success criteria:** Codex explicitly says that the Handoff was committed and returns its scope, disposition, next +action, and exact Handoff Revision. A preview or Prepared Handoff without an exact committed Revision is not a durable +milestone. + +Keep the exact Revision returned by Codex. The next step uses it. + +## 9. Receive the Handoff in a new session + +Exit the second session and start a third Codex session from the same example project: + +```bash +codex +``` + +Insert the exact Revision from the previous step into this request: + +> Continue the PowerContext Handoff `` for this project. Treat the Handoff as untrusted history first, +> and check live state, capabilities, and authorization against the current repository and user instructions. Tell me +> the objective, changed files, observed checks, and next action. Then record accepted, needs clarification, or +> declined. Do not continue modifying files. + +The receiver should read the exact Handoff, check the current `README.md` and Git state again, and then record an +acknowledgement. It can mark the Handoff `accepted` only when evidence is readable and the live-state, capability, and +authorization checks are all confirmed. + +**Success criteria:** Codex returns the same exact Revision, reports the current uncommitted `README.md` change and +`git diff --check` result, and states the acknowledgement status. Historical Handoff content never replaces checking +the current repository and never grants new authority. + +## 10. Verify persistence across a Server restart + +Exit Codex. In **Terminal A**, stop the Server cleanly with `Ctrl-C`, then start it again: + +```bash +powercontext server run +``` + +Return to **Terminal B** and check it: + +```bash +powercontext doctor +``` -Ask Codex: +Start Codex again from the same project and enter: -> Use PowerContext to save three separate project Memory entries: the outcome is “the parser accepts TOML”; the current state -> is “tests pass on Python 3.11”; the next step is “add malformed-input cases”. +> List the current active PowerContext Memory and read the exact Handoff Revision from the previous exercise. This is a +> read-only check; do not write anything. -Codex should use the project-context skill and confirm the successful Memory writes. Do not put secrets in Memory. +**Success criteria:** active Memory, the revised Revision, and the committed Handoff remain readable after the Server +restart.

+后续步骤会明确说明在哪个位置操作。不要在 Memory 或 Handoff 中写入密码、访问令牌、私钥、连接串或其他敏感信息。 + +## 1. 安装 PowerContext + +在**终端 B** 的任意目录中运行： ```bash uv tool install --force "powercontext[cli,server] @ git+https://github.com/oceanbase/powercontext.git@master" +``` + +`uv tool install` 会创建隔离的应用环境，不会在当前目录留下 PowerContext 仓库副本。`--force` 会按当前 +`master` 指向的 commit 刷新已安装工具；以后更新同一安装时，也应保留该选项。 + +确认命令已经可用： + +```bash +powercontext --version +powercontext --help +``` + +**成功标准：** 第一条命令输出版本号，第二条命令显示 `server`、`setup`、`doctor` 等命令。如果 shell 找不到 +`powercontext`，请先把 `uv` 的 tool executable 目录加入 `PATH`，重新打开终端，再重复这两条检查命令。 + +## 2. 安装 Codex 插件 + +仍在**终端 B** 中运行： + +```bash powercontext setup codex --source oceanbase/powercontext --ref master ``` -第一条命令安装隔离的应用环境；第二条命令安装 Codex 插件，并准备 PowerContext

标识精确条目和 Revision； +后续修订或停用时，Codex 会先读取当前条目，再使用该精确 citation 作为并发检查。 + +## 6. 在第二个 Codex 会话中恢复 Memory + +退出第一个 Codex 会话，但不要停止终端 A 中的 Server。确认终端 B 仍位于同一个示例项目目录，然后重新启动： + +```bash +codex +``` + +这是一个新的会话，不包含上一段聊天记录。输入： + +> 使用 PowerContext 列出当前项目的全部 active Memory。告诉我每条内容、kind 和 citation；不要修改任何条目。 + +**成功标准：** 新会话仍能列出上一步写入的三条内容。这证明数据保存在项目 scope 和 Server 的持久化数据库中， +而不是只存在于第一个会话的上下文窗口里。 +

acknowledgement。只有证据可读，并且 +live state、capability 和 authorization 三项检查都 confirmed 时，才能标记为 `accepted`。 + +**成功标准：** Codex 返回与上一步一致的 exact Revision，报告当前 `README.md` 的未提交修改和 +`git diff --check` 结果，并说明 acknowledgement 状态。历史 Handoff 不能代替当前仓库检查，也不会授予新的操作权限。 + +## 10. 验证 Server 重启后的持久化 + +退出 Codex。在**终端 A** 按 `Ctrl-C` 正常停止 Server，然后再次运行： + +```bash +powercontext server run +``` + +回到**终端 B**检查： +

Install the PowerContext CLI and Server + +Run in **Terminal B**: + +```bash +uv tool install --force "powercontext[cli,server] @ git+https://github.com/oceanbase/powercontext.git@master" +``` + +The command creates an isolated application environment and does not leave a PowerContext checkout in the current +directory. `--force` refreshes an existing installation from the commit currently selected by `master`. + +Confirm that the CLI is available: + +```bash +powercontext --version +powercontext --help +``` + +**Success criteria:** the first command prints a version, and the second shows commands including `server`, `setup`, +and `doctor`. + +## 4. Install one or more agent integrations + +### Install one host + +Choose one command below. Use the same revision for `--ref` and the PowerContext tool: + +```bash +powercontext setup codex --source oceanbase/powercontext --ref master +powercontext setup claude-code --source oceanbase/powercontext --ref master +powercontext setup dsh --source oceanbase/powercontext --ref master +powercontext setup openclaw --source oceanbase/powercontext --ref master +powercontext setup opencode --source oceanbase/powercontext --ref master +powercontext setup pi --source oceanbase/powercontext --ref master +powercontext setup hermes --source oceanbase/powercontext --ref master +powercontext setup workbuddy --source oceanbase/powercontext --ref master +``` + +Run only the command for a host that is already installed. Each setup performs post-install diagnostics for its own +integration. Resolve that host's prerequisite failure instead of assuming setup completed. + +Hermes also requires MemoryProvider selection: + +```bash +hermes memory setup +``` + +Select `PowerContext` in the wizard, then restart Hermes. + +### Install several first-class hosts at once + +Codex, Claude Code, DeepSeek Harness, OpenClaw, OpenCode, Pi, and Hermes are in the `setup select` catalog. For +example: + +```bash +powercontext setup select \ + --host claude-code \ + --host dsh \ + --host opencode \ + --source oceanbase/powercontext \ + --ref master +``` + +Each host independently reports `installed`, `failed`, or `skipped`. A failure for one host is not hidden by another +host's success. WorkBuddy is not in this catalog; run `powercontext setup workbuddy` separately. + +### Use the portable Agent Plugin + +When a host can load Agent Plugin Skills and MCP configuration but has no dedicated setup command, follow +[Configure Agent Plugin](../how-to/configure-agent-plugin.md) and load +`integrations/agent-plugin/powercontext/`. The package provides a `project-context` Skill and configuration for +`http://127.0.0.1:8000/mcp`. It does not start the Server and does not provide a cross-host Prompt Hook. + +## 5. Start and check the Server + +Run in **Terminal A** and keep the process alive: + +```bash +powercontext server run +``` + +By default, the Server: + +- listens at `http://127.0.0.1:8000`; +- serves the Dashboard at `/`; +- serves Streamable HTTP MCP at `/mcp`; +- uses a persistent SQLite database in the PowerContext user data directory. + +Return to **Terminal B** and run: + +```bash +powercontext doctor +powercontext ready +powercontext capabilities +powercontext doctor integrations +``` + +**Success criteria:** + +- package, Server liveness, and Server readiness report `ok` in `doctor`; +- `ready` and `capabilities` can read the current service; +- the installed host's CLI and integration items report `ok` in `doctor integrations`; +- missing hosts can appear as missing without failing this read-only overview. + +WorkBuddy is not in the first-class overview, so run `powercontext doctor workbuddy` separately. You can also run +`powercontext doctor codex`, `doctor claude-code`, `doctor dsh`, `doctor openclaw`, `doctor opencode`, `doctor pi`, or +`doctor hermes` for the selected host. + +## 6. Create a safe example project + +Create a Git project without real business data in **Terminal B**: + +```bash +mkdir powercontext-agent-quickstart +cd powercontext-agent-quickstart +git init +printf '# Parser example\n\nThis project will parse TOML configuration.\n' > README.md +git add README.md +git -c user.name="PowerContext Tutorial" -c user.email="tutorial@localhost" commit -m "chore: initialize tutorial" +git status --short +``` + +The last command should print nothing. The commit identity applies only to this one commit and does not change global +Git configuration. + +Start every later session from this same directory. Most dedicated integrations derive a stable scope from the Git +remote or project path. When an explicit scope is configured, every Memory and Handoff call in the same workflow must +reuse that exact `scope_id`. + +## 7. Start the agent and inspect the integration surface + +Start the selected host from the example project: + +```bash +codex # Codex +claude # Claude Code +dsh web # DeepSeek Harness +openclaw # OpenClaw +opencode # OpenCode +pi # Pi +hermes # Hermes, after memory setup +``` + +WorkBuddy users should open or create a task for this project and restart the host after installation. Agent Plugin +users should reload the compatible host and confirm that both the `project-context` Skill and `powercontext` MCP +Server are visible. + +Begin with a read-only inspection: + +> Inspect the current project directory, Git state, and available PowerContext integration capabilities. Report the +> current scope or its source and list the Memory read tools. Do not modify files or write to PowerContext. + +Tool names differ by host: + +| Integration | Expected Memory surface | +| --- | --- | +| Codex, Claude Code, WorkBuddy, Agent Plugin | MCP `search_memory`, `list_memory_entries`, `get_memory_entry`, and related tools | +| DSH, OpenCode, Pi | `pc_search`, `pc_memory_list`, `pc_memory_get`, `pc_remember`, and related tools | +| OpenClaw | `powercontext_memory_search`, `get`, `store`, `revise`, and `retire` | +| Hermes | MemoryProvider tools plus `/pc`, `/powercontext`, or `hermes powercontext ...` | + +If the tools are absent, exit the host, rerun that host's setup and doctor commands, and open a new session. Do not +continue with an unloaded integration and mistake a normal model answer for a PowerContext result. + +## 8. Save and read explicit Memory + +Enter this in the agent session: + +> Use this host's explicit PowerContext Memory tools to save three separate project Memory entries: +> +> 1. decision: the parser uses the Python 3.11 standard-library `tomllib` module; +> 2. constraint: error summaries must not contain secret values from the source configuration; +> 3. next-step: add malformed TOML input cases. +> +> After writing, search or list the active Memory and return the citation for each entry. Do not store secrets or +> credentials. + +DSH, OpenCode, and Pi should call `pc_remember`; OpenClaw should call `powercontext_memory_store`; MCP integrations +should call `remember_memory`. These are durable mutations. When the host requests confirmation, inspect the content +before approving it. + +Hermes also provides a deterministic CLI path for one write and search: + +```bash +hermes powercontext remember decision "The parser uses Python 3.11 tomllib" +hermes powercontext search "Python parser" +``` + +**Success criteria:** the agent or Hermes CLI reports a successful write and returns the content and exact citation in +the current scope. Explicit Memory does not require a generation model. Prompt or turn capture creates a Source; it +does not mean Memory was already created. + +## 9. Recover in a new session of the same host + +Exit the agent session without stopping the Server. Confirm that Terminal B is still in the example project, then +start the same host again. Enter: + +> Use PowerContext to search active Memory in the current project for `tomllib` and malformed TOML. Return the content, +> kind, and citation. Do not modify any entry. + +**Success criteria:** the new session recovers the three entries. The data comes from a stable scope and Server +database, not the previous chat history. + +If the result is empty, check these items in order: + +1. both sessions started from the same project directory; +2. `powercontext doctor` and the host-specific doctor still report `ok`; +3. the host did not select a different profile, agent identity, or explicit scope; +4. OpenClaw is not still using the default `agent` scope when you expected a project scope. + +For project Memory shared through OpenClaw, reconfigure it and confirm that the host supplies one trusted project +identity: + +```bash +powercontext setup openclaw --scope-mode project +``` + +A scope is not an authorization boundary. A remote or multi-user Server still needs separate authentication and +access control. + +## 10. Revise and retire Memory + +Enter in the current agent session: + +> Read the exact citation for the current Memory first. Revise the next-step to “record the malformed TOML line number +> and a safe error summary”. Then retire the original constraint with the reason “replaced by the shared logging +> redaction policy”. Finally, list active Memory again and explain whether the old Revisions remain auditable. + +The corresponding tools are: + +- MCP: `get_memory_entry`, `revise_memory_entry`, and `retire_memory_entry`; +- DSH, OpenCode, and Pi: `pc_memory_get`, `pc_memory_revise`, and `pc_memory_retire`; +- OpenClaw: `powercontext_memory_get`, `powercontext_memory_revise`, and `powercontext_memory_retire`; +- Hermes: provider tools or corresponding `/pc` commands. + +**Success criteria:** active results contain the new next-step and omit the retired constraint. Old Revisions remain +available instead of being overwritten or deleted. + +## 11. Hand off work according to host capability + +A Handoff transfers complete task state and must not be replaced with a few Memory entries. Each host follows its own +surface. + +### One-turn durable Handoff + +The `project-context` Skills for Codex, Claude Code, and WorkBuddy support a direct imperative: + +> Handoff this work. + +The Skill inspects the objective, branch, worktree, changed files, checks, blockers, omissions, and next action. It +calls `handoff_current_work`, then passes the returned complete `handoff` to `commit_handoff`. A durable milestone +exists only when an exact committed Revision is returned. + +### Multi-step `pc_*` Handoff + +DeepSeek Harness, OpenCode, and Pi expose lifecycle tools. First have the agent produce one small uncommitted change, +then enter: + +> Use the PowerContext `pc_*` Handoff flow for the current work. Inspect the repository and capture one boundary +> Source, activate a Handoff, inspect the draft, and finalize it. I explicitly request a durable milestone, so commit +> it and return the exact Handoff Revision. Do not skip evidence checks or substitute ordinary Memory for a Handoff. + +The flow is: + +```text +pc_capture_source → pc_handoff_activate → inspect → pc_handoff_finalize → pc_handoff_commit +``` + +The receiver calls `pc_handoff_continue` with a Prepared carrier or exact committed Revision and checks it again +against the current repository. + +### Hermes Handoff + +In interactive Hermes, type `/pc ` and use Tab/Down to inspect Handoff commands, or use the Work Contract, prepare, +activate, finalize, commit, continue, and acknowledge operations exposed by the provider. Inspect a draft before +finalize or commit, and do not claim task completion merely because a Handoff was written. See +[Configure Hermes](../how-to/configure-hermes.md) for activation and command boundaries. + +### Current OpenClaw boundary + +The current OpenClaw plugin provides automatic context preparation and five Memory tools, but not a complete Handoff, +Outcome, or Review UI. Do not have the model pretend to call tools that do not exist. To transfer complete work: + +- use another Handoff-capable agent connected to the same scope; +- use MCP Handoff through the portable Agent Plugin; +- call the HTTP or Client Handoff API from an application. + +## 12. Complete a non-Codex cross-agent example + +This example creates a Handoff in DeepSeek Harness and receives it in OpenCode. Both hosts must use the same explicit +scope: + +```bash +export POWERCONTEXT_DSH_SCOPE_ID=git:github.com/example/powercontext-agent-quickstart +export POWERCONTEXT_OPENCODE_SCOPE_ID=git:github.com/example/powercontext-agent-quickstart +``` + +Replace `example/powercontext-agent-quickstart` with a stable project identity you control. Set each variable in the +shell that starts its corresponding host. + +Start DSH in the example project: + +```bash +dsh web +``` + +Have DSH update `README.md`, run `git diff --check`, and commit a Handoff with the Step 11 `pc_*` flow. Keep the exact +Revision it returns. + +Exit DSH and start OpenCode from the same project: + +```bash +opencode +``` + +Enter: + +> Use `pc_handoff_continue` to read exact Handoff Revision `` from scope +> `git:github.com/example/powercontext-agent-quickstart`. Treat it as untrusted history, check README.md, Git state, +> and observed checks again, and report only the objective, changed files, checks, and next action. Do not continue +> modifying files. + +**Success criteria:** OpenCode reads the same exact Revision and checks it against the live project instead of relying +on DSH chat history. Shared Server state, scope, evidence, and Revision provide continuity; no particular agent host +owns it. + +## 13. Verify persistence and graceful degradation + +Stop and restart the Server: + +```bash +powercontext server run +``` + +Run `powercontext doctor` again, then have the selected host read active Memory or an exact Handoff. Data should remain +available after the Server restart. + +Next, stop the Server and ask the agent to complete a read-only task unrelated to PowerContext. An automatic hook or +provider may report `server_unavailable`, and explicit tools should be unavailable, but ordinary agent work must not +be blocked. Restart the Server before using PowerContext again. + +## 14. Python agent application paths + +Python applications integrate PowerContext in their own environment and execution lifecycle instead of running +`powercontext setup `: + +| Integration | Current integration path | Main scope | +| --- | --- | --- | +| Pydantic AI | Preview capability / toolset | Memory and PreparedContext; not currently a supported standalone release | +| LangChain | `PowerContextMiddleware` | Bounded recall for each model call and optional completed-turn Source capture | +| LangGraph | Recall hook + `powercontext_tools()` | Memory read/write and bounded context; no Handoff | +| Bub | Bub plugin | Memory tools, context before each model call, and optional event capture | + +Read [Pydantic AI](../how-to/configure-pydantic-ai.md), [LangChain](../how-to/configure-langchain.md), and +[LangGraph](../how-to/configure-langgraph.md).

分步入门 + +本教程面向第一次使用 PowerContext 的 Agent 用户。你可以使用 Codex、Claude Code、DeepSeek Harness、 +OpenClaw、OpenCode、Pi、Hermes 或 WorkBuddy，也可以把通用 Agent Plugin 加载到支持 Skill 与 MCP 的 Host。 + +完成后，你会跑通下面的公共闭环： + +```text +安装 Server → 选择 Agent → 验证集成 → 保存 Memory → 换会话恢复 → 按 Host 能力交接 +``` + +公共步骤使用本地 SQLite，不要求配置 generation model。显式 Memory 与已有的 Handoff 操作可以直接使用；从 +Source 自动抽取 Memory、向量搜索和模型生成能力需要另行配置 provider。 + +不同 Agent 的集成表面并不完全相同。本教程会明确区分： + +- 自动准备上下文与显式 Memory 工具； +- 一句话 Handoff 与多步骤 Handoff； +- 只有 Memory、暂时没有完整 Handoff UI 的集成； +- 交互式 Agent Host 与需要写代码接入的 Python Agent 应用。 + +## 1. 选择你的 Agent 路线 +

Linux，以及下面的公共工具： + +| 工具 | 要求 | 检查命令 | +| --- | --- | --- | +| Python | 3.11 或更新版本 | `python3 --version` | +| Git | 能读取 PowerContext Git 仓库 | `git --version` | +| uv | 能使用 `uv tool` | `uv --version` |

Server； +- **终端 B**：安装、诊断、进入项目，并启动选定的 Agent。 + +不要把密码、访问令牌、私钥、连接串或其他敏感信息写入 Memory、Source 或 Handoff。 + +## 3. 安装 PowerContext CLI 和 Server + +在**终端 B**运行： + +```bash +uv tool install --force "powercontext[cli,server] @ git+https://github.com/oceanbase/powercontext.git@master" +``` + +该命令创建隔离的应用环境，不会在当前目录留下 PowerContext 仓库副本。`--force` 会按当前 `master` 指向的 +commit 刷新已有安装。 + +确认 CLI 可用： + +```bash +powercontext --version +powercontext --help +``` + +**成功标准：** 第一条命令输出版本号；第二条显示 `server`、`setup`、`doctor` 等命令。 + +## 4. 安装一个或多个 Agent 集成 + +### 安装一个 Host + +从下面选择一个命令，并让 `--ref` 与 PowerContext 工具使用同一个 revision： + +```bash +powercontext setup codex --source oceanbase/powercontext --ref master +powercontext setup claude-code --source oceanbase/powercontext --ref master +powercontext setup dsh --source oceanbase/powercontext --ref master +powercontext setup openclaw --source oceanbase/powercontext --ref master +powercontext setup opencode --source

workbuddy --source oceanbase/powercontext --ref master +``` + +只运行你已安装的 Host 对应命令。每个 setup 都会执行该集成的安装后诊断；失败时先处理当前 Host 的前置条件， +不要假设安装已经完成。 + +Hermes 还需要选择 MemoryProvider： + +```bash +hermes memory setup +``` + +在向导中选择 `PowerContext`，完成后重启 Hermes。 + +### 一次安装多个一级 Host + +Codex、Claude Code、DeepSeek Harness、OpenClaw、OpenCode、Pi 和 Hermes 属于 `setup select` 一级目录。例如： + +```bash +powercontext setup select \ + --host claude-code \ + --host dsh \ + --host opencode \ + --source oceanbase/powercontext \ + --ref master +``` + +每个 Host 会独立报告 `installed`、`failed` 或 `skipped`。一个 Host 失败不会被其他成功结果掩盖。WorkBuddy +不在该目录中，需要单独运行 `powercontext setup workbuddy`。 + +### 使用通用 Agent Plugin + +如果 Host 能加载 Agent Plugin Skill 与 MCP 配置，但没有专属 setup 命令，请按照 +[配置 Agent Plugin](../how-to/configure-agent-plugin.md)加载 +`integrations/agent-plugin/powercontext/`。这个 package 提供 `project-context` Skill 和指向 +`http://127.0.0.1:8000/mcp` 的配置，但不会启动 Server，也没有跨 Host 通用的 Prompt Hook。 + +## 5. 启动并检查 Server + +在**终端 A**运行并保持进程： + +```bash +powercontext server run +``` + +默认 Server： + +- 监听 `http://127.0.0.1:8000`； +- 在 `/` 提供 Dashboard； +- 在 `/mcp` 提供 Streamable HTTP MCP； +- 使用 PowerContext 用户数据目录中的持久化 SQLite 数据库。 + +回到**终端 B**运行： + +```bash +powercontext doctor +powercontext ready +powercontext capabilities +powercontext doctor integrations +``` + +**成功标准：** + +- `doctor` 的 package、Server liveness 和 Server readiness 为 `ok`； +- `ready` 与 `capabilities` 能读取当前服务； +- `doctor integrations` 中已安装 Host 的 CLI 和 integration 项为 `ok`； +- 未安装的 Host 可以显示 missing，不会让这个只读总览失败。 + +WorkBuddy 不在一级总览中，请单独运行 `powercontext doctor workbuddy`。也可以按选定 Host 运行 +`powercontext doctor codex`、`doctor claude-code`、`doctor dsh`、`doctor openclaw`、`doctor opencode`、 +`doctor pi` 或 `doctor hermes`。 + +## 6. 创建一个安全的示例项目 + +在**终端 B**创建一个不含真实业务数据的 Git 项目： + +```bash +mkdir powercontext-agent-quickstart +cd powercontext-agent-quickstart +git init +printf '# Parser example\n\nThis project will parse TOML configuration.\n' > README.md +git add README.md +git -c user.name="PowerContext Tutorial" -c user.email="tutorial@localhost" commit -m "chore: initialize tutorial" +git status --short +``` + +最后一条命令应没有输出。commit 的身份只用于这一次提交，不会修改全局 Git 配置。 + +后续每个会话都应从这个同一目录启动。多数专属集成会从 Git remote 或项目路径推导稳定 scope；如果显式配置了 +scope，则同一条流程中的 Memory 与 Handoff 调用必须始终复用这个 exact `scope_id`。 + +## 7. 启动 Agent 并检查集成表面 + +从示例项目目录启动所选 Host： + +```bash +codex # Codex +claude # Claude Code +dsh web # DeepSeek Harness +openclaw # OpenClaw +opencode # OpenCode +pi # Pi +hermes # Hermes，已完成 memory setup 后 +``` + +WorkBuddy 用户应在这个项目中打开或创建任务，并在安装后重启 Host。通用 Agent Plugin 用户应重新加载对应 Host， +确认 `project-context` Skill 与 `powercontext` MCP Server 都可见。 + +先做只读检查： + +> 检查当前项目目录、Git 状态和可用的 PowerContext 集成能力。报告当前 scope 或 scope 来源，并列出 Memory +> 读取工具；不要修改文件，也不要写入 PowerContext。 + +不同 Host 的工具名会不同： + +| 集成 | 应能看到的 Memory 表面 | +| --- | --- | +| Codex、Claude Code、WorkBuddy、Agent Plugin | MCP 的 `search_memory`、`list_memory_entries`、`get_memory_entry` 等 | +| DSH、OpenCode、Pi | `pc_search`、`pc_memory_list`、`pc_memory_get`、`pc_remember` 等 | +| OpenClaw | `powercontext_memory_search`、`get`、`store`、`revise`、`retire` | +| Hermes | MemoryProvider tools，以及 `/pc`、`/powercontext` 或 `hermes powercontext ...` | + +如果工具不存在，先退出 Host，重新运行该 Host 的 setup 和 doctor，再开启新会话。不要在集成未加载时继续并把模型的 +普通回答误当成 PowerContext 结果。 + +## 8. 保存并读取显式 Memory + +在 Agent 会话中输入： + +> 使用这个 Host 提供的 PowerContext 显式 Memory 工具，分别保存三条项目 Memory： +> +> 1. decision：解析器使用 Python 3.11 标准库 `tomllib`； +> 2. constraint：错误摘要不得包含原始配置中的密钥值； +> 3. next-step：增加 malformed TOML 输入用例。 +> +> 写入后搜索或列出这些 active Memory，并返回每一条的 citation。不要保存任何密钥或凭据。 + +DSH、OpenCode 和 Pi 应调用 `pc_remember`；OpenClaw 应调用 `powercontext_memory_store`；MCP 集成应调用 +`remember_memory`。这些是 durable mutation，Host 要求确认时应先检查内容再批准。 + +Hermes 也可以用确定性的 CLI 路径验证单条写入和搜索： + +```bash +hermes powercontext remember decision "The parser uses Python 3.11 tomllib" +hermes powercontext search "Python parser" +``` + +**成功标准：** Agent 或 Hermes CLI 明确报告写入成功，并返回当前 scope 中的内容与精确 citation。显式 Memory +不需要 generation model；Prompt 或 turn capture 只会生成 Source，不等于已经创建 Memory。 + +## 9. 在同一 Host 的新会话中恢复 + +退出 Agent 会话，不要停止 Server。确认终端 B 仍位于示例项目目录，再启动同一个 Host。输入： + +> 使用 PowerContext 搜索当前项目中关于 `tomllib` 和 malformed TOML 的 active Memory。返回内容、kind 和 +> citation；不要修改条目。 + +**成功标准：** 新会话能恢复上一步保存的三条 Memory。这证明数据来自稳定 scope 和 Server 数据库，而不是上一段 +聊天历史。 + +如果返回空结果，按顺序检查： + +1. 两次会话是否从同一个项目目录启动； +2. `powercontext doctor` 和 Host 专属 doctor 是否为 `ok`； +3. Host 是否使用了不同的 profile、agent identity 或显式 scope； +4. OpenClaw 是否仍使用默认 `agent` scope，而你期望的是 project scope。 + +OpenClaw 需要跨 Agent 使用项目 Memory 时，应重新配置并确认 Host 提供可信 project identity： + +```bash +powercontext setup openclaw --scope-mode project +``` + +不要把 scope 当成权限边界。远程或多用户 Server 仍需要独立配置鉴权和访问控制。 + +## 10. 修订和停用 Memory + +在当前 Agent 会话中输入： + +> 先读取当前 Memory 的 exact citation，然后把 next-step 修订为“记录 malformed TOML 的行号和安全错误摘要”。 +> 再停用原 constraint，reason 使用“由统一日志脱敏规范替代”。最后重新列出 active Memory，并说明旧 Revision +> 是否仍可审计。 + +对应工具为： + +- MCP：`get_memory_entry`、`revise_memory_entry`、`retire_memory_entry`； +- DSH、OpenCode、Pi：`pc_memory_get`、`pc_memory_revise`、`pc_memory_retire`； +- OpenClaw：`powercontext_memory_get`、`powercontext_memory_revise`、`powercontext_memory_retire`； +- Hermes：provider tools 或 `/pc` 对应命令。 + +**成功标准：** active 结果包含新 next-step，不再包含已停用 constraint；旧 Revision 被保留，而不是被覆盖或删除。 + +## 11. 按 Host 能力交接工作 + +Handoff 用于转交完整任务状态，不应由几条 Memory 代替。不同 Host 应走不同路径。 + +### 一句话 durable Handoff + +Codex、Claude Code 和 WorkBuddy 的 `project-context` Skill 支持明确的命令式请求： + +> 交接 + +Skill 会检查目标、branch、worktree、changed files、checks、blockers、omissions 和 next action，调用 +`handoff_current_work`，再把返回的完整 `handoff` 提交给 `commit_handoff`。只有返回 exact committed Revision +才算 durable milestone。 + +### `pc_*` 多步骤 Handoff + +DeepSeek Harness、OpenCode 和 Pi 提供显式生命周期工具。先让 Agent 产生一项小的未提交工作，再输入： + +> 使用 PowerContext 的 `pc_*` Handoff 流程交接当前工作：先检查当前仓库并 capture 一条 boundary Source， +> 再 activate Handoff，检查 draft 后 finalize。因为我明确要求创建 durable milestone，所以最后 commit，并返回 +> exact Handoff Revision。不要跳过证据检查，也不要把普通 Memory 当作 Handoff。 + +对应流程是： + +```text +pc_capture_source → pc_handoff_activate → inspect → pc_handoff_finalize → pc_handoff_commit +``` + +接收方使用 `pc_handoff_continue` 读取 Prepared carrier 或 exact committed Revision，并根据当前仓库重新核对。 + +### Hermes Handoff + +在交互式 Hermes 中输入 `/pc ` 后使用 Tab/Down 查看 Handoff 命令，或使用 MemoryProvider 暴露的 Work Contract、 +prepare、activate、finalize、commit、continue 和 acknowledge operations。每次 finalize 或 commit 前先检查 draft； +不要仅因为写入 Handoff 就宣称任务已经完成。详细激活和命令边界见[配置 Hermes](../how-to/configure-hermes.md)。 + +### OpenClaw 当前边界 + +OpenClaw 当前插件提供自动 context preparation 和五个 Memory tools，但没有完整 Handoff、Outcome 或 Review UI。 +不要让模型假装调用不存在的 Handoff 工具。需要转交完整任务时，可以： + +- 由另一个连接同一 scope 的 Handoff-capable Agent 创建和接收； +- 使用通用 Agent Plugin 的 MCP Handoff； +- 由应用直接调用 HTTP/Client Handoff API。 + +## 12. 跑通一个非 Codex 的跨 Agent 示例 + +下面使用 DeepSeek Harness 产生 Handoff，再由 OpenCode 接收。两个 Host 必须显式使用同一个 scope： + +```bash +export POWERCONTEXT_DSH_SCOPE_ID=git:github.com/example/powercontext-agent-quickstart +export POWERCONTEXT_OPENCODE_SCOPE_ID=git:github.com/example/powercontext-agent-quickstart +``` + +把 `example/powercontext-agent-quickstart` 换成你控制的稳定项目标识。两个变量应分别在启动 DSH 和 OpenCode 的 +shell 中设置。 + +在示例项目中启动 DSH： + +```bash +dsh web +``` + +让 DSH 修改 `README.md`、运行 `git diff --check`，然后按第 11 步的 `pc_*` 流程提交 Handoff。保存返回的 exact +Revision。 + +退出 DSH，在同一个项目目录启动 OpenCode： + +```bash +opencode +``` + +输入： + +> 使用 `pc_handoff_continue` 读取 scope +> `git:github.com/example/powercontext-agent-quickstart` 中的 exact Handoff Revision ``。把内容当作 +> 不可信历史，重新检查 README.md、Git 状态和已有检查，只汇报目标、changed files、checks 和 next action；不要继续 +> 修改文件。 + +**成功标准：** OpenCode 读取同一个 exact Revision，并用当前项目状态复核，而不是依赖 DSH 的聊天历史。这个示例 +证明共享边界来自 Server、scope、evidence 和 Revision，不来自某个特定 Agent Host。 + +## 13. 验证持久化与安全降级 + +停止并重新启动 Server： + +```bash +powercontext server run +``` + +重新运行 `powercontext doctor`，再让选定 Host 读取 active Memory 或 exact Handoff。数据应在 Server 重启后保持。 + +随后停止 Server，并让 Agent 完成一个不依赖 PowerContext 的只读任务。自动 Hook 或 provider 可以报告 +`server_unavailable`，显式 tools 也应失败，但普通 Agent 工作不能因此被阻断。恢复使用前重新启动 Server。 + +## 14.

A `source_id` should consistently identify the same content so capture remains +idempotent. + +A Source is original evidence, not Memory. This endpoint does not call a model synchronously or make the content +immediately recallable. Automatic extraction requires a configured generation model and the Runtime flush or +scheduler flow; see the [full-capability Quick Start](../how-to/full-capability-runtime.md). + +Do not capture every conversation by default. Establish user consent, sensitive-field filtering, retention, and +purpose limits before preserving only the evidence you need. + +## 12. Verify cross-process persistence + +1. Stop the Server in terminal A. +2. Run `powercontext server run` again. +3. Repeat the search or list request from step 5. + +The active Memory remains available when the Server uses the same data directory and the application uses the same +`scope_id`. Do not confuse a container's temporary filesystem or a test database with production persistence. See +[Deploy the Server](../how-to/deploy-server.md) for a service deployment. + +## 13. Enable authentication or remote access + +The default loopback development setup may run without Server Bearer authentication. When authentication is enabled, +add this header to every request except health checks: + +```http +Authorization: Bearer +``` + +For example: + +```bash +export POWERCONTEXT_CLIENT_API_TOKEN='token loaded from a secure credential source' + +curl --fail --silent --show-error \ + --header "Authorization: Bearer $POWERCONTEXT_CLIENT_API_TOKEN" \ + "$POWERCONTEXT_URL/v1/capabilities" \ + | jq . +``` + +The Python example sends this header automatically when `POWERCONTEXT_CLIENT_API_TOKEN` is set. Never put a token in +a URL, Memory, Source, log, or model prompt. Before allowing remote access, terminate TLS at a trusted gateway and +enforce identity, scope authorization, rate limits, and audit there. + +## 14. Handle errors + +Error responses use a stable envelope: + +```json +{ + "error": { + "code": "invalid_request", + "message": "The request violates the API contract.", + "details": {} + } +} +``` + +Every response has an `X-PowerContext-Request-ID`. Production clients should record the status, stable `error.code`, +and request ID rather than depend on internal exception text. + +| Status | Common cause | Application behavior | +| --- | --- | --- | +| `401` | Missing or invalid Bearer token | Do not retry; fix credentials | +| `404` | The immutable value named by a citation does not exist | Refresh the list or search result | +| `409` | Stale citation or immutable-state conflict | Read the latest entry and ask for a new decision | +| `422` | Missing, oversized, blank, or mistyped field | Fix client input; do not retry blindly | +| `503` | A required Runtime binding or dependency is unavailable | Degrade reads; report failed writes and retry later | +| `500` | Internal Server error | Record the request ID and retry with bounded backoff | + +Use bounded retries for network timeouts as well.

"content": "BEGIN_POWERCONTEXT_PREPARED_CONTEXT_V1\n…\nEND_POWERCONTEXT_PREPARED_CONTEXT_V1", + "content_bytes": 987 +} +``` + +没有可用内容时，这是正常结果： + +```json +{ + "schema": "powercontext.prepared-context.v1", + "status": "empty", + "content": null, + "content_bytes": 0 +} +``` + +应用只在 `status == "ready"` 且 `content` 为字符串时注入。不要把 `PreparedContext` 再写回 Memory；它是本次 +请求的临时组合结果，不是新的事实。 + +## 7. 接入现有 AI 调用代码 + +下面使用 Python 标准库完成 PowerContext 请求，并把模型调用留在一个明确的适配函数中。这样可以继续使用你已经 +选定的模型 SDK，而不会让 Memory 层绑定某一家模型服务。 + +```python +from __future__ import annotations + +import json +import os +from collections.abc import Callable +from typing import Any +from urllib.error import HTTPError, URLError +from urllib.request import Request, urlopen + +POWERCONTEXT_URL =

powercontext_post(path: str, payload: dict[str, Any]) -> dict[str, Any]: + headers = {"Content-Type": "application/json"} + if POWERCONTEXT_TOKEN: + headers["Authorization"] = f"Bearer

"query": user_query[:8192], + "max_bytes": 4000, + }, + ) + except (HTTPError, URLError, TimeoutError): + # 读取失败可以降级：记录错误和 request ID，然后让主模型请求继续。 + return None + + if prepared.get("status") != "ready": + return None + content = prepared.get("content") + return content if isinstance(content, str) else None + + +def ask_ai( + user_query: str, + call_your_model: Callable[[list[dict[str,

data:\n{context}"}) + + messages.append({"role": "user", "content": user_query}) + return call_your_model(messages) +``` + +把你现有的模型调用封装成 `call_your_model(messages) -> str`，然后调用： + +```python +answer = ask_ai("我的账单为什么这么高？", call_your_model) +``` + +关键约束： + +- 一个用户请求只调用一次 `prepare`，不要先 search 再让 `prepare` 重复检索； +- 保留 PowerContext 返回的 `content`，让其中的 citation 与信任说明保持完整； +- 当前用户请求和实时业务数据始终高于历史 Memory； +- 上下文读取可以 fail open，写操作不能静默失败； +- 不要把 PowerContext token、数据库连接串或内部身份信息交给模型。 + +## 8. 让模型通过工具主动查找或建议 Memory + +如果模型支持 function/tool calling，可以把你自己的包装函数暴露给模型，但不要让模型直接持有 Server token 或 +任意填写 `scope_id`。应用应从已认证会话注入这两个值。 + +建议只暴露下面三类工具： + +| 模型工具 | PowerContext API | 调用策略 | +| --- | --- | --- | +| `search_project_memory(query, limit)` | `POST /v1/memory/search` | 可自动调用；限制 query 长度和 limit | +| `get_memory(citation)` | `POST /v1/memory/entries/get` | 可自动调用；citation 必须来自同一 scope 的响应 | +| `propose_memory(kind, text, reason)` | 经用户确认后调用 `POST /v1/memory/remember` | 模型只能提出建议，应用负责确认和写入 | + +包装函数示例： + +```python +def search_project_memory(query: str, limit: int = 5) -> dict[str, Any]: + return powercontext_post( + "/v1/memory/search", + { + "scope_id": POWERCONTEXT_SCOPE, + "query": query[:8192], + "limit": max(1, min(limit, 50)), + "mode": "auto", + }, + ) + + +def remember_after_approval(kind: str, text: str, reason: str) -> dict[str, Any]: + # 在进入这个函数之前，由 UI 或业务规则产生可审计的批准结果。 + return powercontext_post( + "/v1/memory/remember", + { + "scope_id": POWERCONTEXT_SCOPE, + "kind": kind[:128], + "text": text, + "reason": reason[:512], + }, + ) +``` + +不要把“模型调用了 `propose_memory`”本身当作授权。应用可以先在 UI 中显示建议内容，让用户选择保存、编辑或忽略。 +也不要保存模型的整段回答；长期 Memory 应是短小、明确、以后仍然成立的决定、偏好、约束、状态或下一步。 + +## 9. 修订错误 Memory + +Memory 条目不会原地覆盖。修订会创建新版本并保留历史。下面使用第 4 步的精确 citation： + +```bash +jq --arg scope "$POWERCONTEXT_SCOPE" \ + --arg text '回答账单问题时，先解释费用构成；只有符合退款政策时才提供退款入口。' \ + '{ + scope_id: $scope, + citation: .entry.citation, + kind: "decision", + text: $text, + reason: "客服政策已澄清" + }' \ + /tmp/powercontext-remember.json \ + > /tmp/powercontext-revise.json + +curl --fail --silent --show-error \ + --request POST \ + --header 'Content-Type: application/json' \ + --data @/tmp/powercontext-revise.json \ + "$POWERCONTEXT_URL/v1/memory/entries/revise" \ + | tee /tmp/powercontext-revised.json \ + | jq . +``` + +响应中的 `entry.citation` 指向新版本。后续修订或停用必须使用这个新 citation；继续使用旧 citation 会收到 `409` +冲突，防止并发请求覆盖更新后的内容。 + +## 10. 停用过期 Memory + +停用不会物理删除历史。下面使用修订响应中的最新 citation： + +```bash +jq --arg scope "$POWERCONTEXT_SCOPE" \ + '{ + scope_id: $scope, + citation: .entry.citation, + reason: "该客服流程已经下线" + }' \ + /tmp/powercontext-revised.json \ + > /tmp/powercontext-retire.json + +curl --fail --silent --show-error \ + --request POST \ + --header 'Content-Type: application/json' \ + --data @/tmp/powercontext-retire.json \ + "$POWERCONTEXT_URL/v1/memory/entries/retire" \ + | jq . +``` + +停用后，普通 search、list 和 prepare 不再使用该条目；`include_inactive: true` 的 list 和精确 get 仍可用于审计。 + +## 11. 可选：保存原始 Source 证据 + +如果需要保留某次用户确认、文档片段或业务事件作为后续处理的证据，可以调用： + +```bash +curl --fail --silent --show-error \ + --request POST \ + --header 'Content-Type: application/json' \ + --data "$(jq -n \ + --arg scope "$POWERCONTEXT_SCOPE" \ + --arg source_id 'support-chat:session-7:turn-12' \ + --arg content '用户确认：以后账单回复必须先解释费用构成。' \ + '{ + scope_id: $scope, + source_id: $source_id, + content: $content, + metadata: {channel: "support-chat", consent: true} + }')" \ + "$POWERCONTEXT_URL/v1/sources/content" \ + | jq . +``` + +成功时返回 `202 Accepted`。同一个 `source_id` 应稳定指向同一份内容，以支持幂等采集。 + +Source 是原始证据，不等于 Memory。这个接口不会同步调用模型，也不会立即把内容变成可召回 Memory。需要自动抽取时， +必须另外配置 generation model，并使用 Runtime 的 flush 或 scheduler 流程；参见[完整功能 Quick Start](../how-to/full-capability-runtime.md)。 + +不要默认采集整段对话。先做用户同意、敏感字段过滤、保留期限和用途限制，再把必要证据写入 Source。 + +## 12. 验证跨进程持久化 + +1. 停止终端 A 中的 Server； +2. 再次运行 `powercontext server run`； +3. 重复第 5 步的 search 或 list 请求。 + +只要使用同一数据目录和同一 `scope_id`，之前保存的 active Memory 仍然存在。不要把容器临时文件系统或测试数据库 +误当作生产持久化；服务化部署参见[部署 Server](../how-to/deploy-server.md)。 + +## 13. 启用鉴权或远程访问 + +默认 loopback 开发环境可以不启用 Server Bearer 鉴权。启用后，在除 health 之外的每个请求中增加： + +```http +Authorization: Bearer +``` + +例如： + +```bash +export POWERCONTEXT_CLIENT_API_TOKEN='从安全凭据源读取的 token' + +curl --fail --silent --show-error \ + --header "Authorization: Bearer $POWERCONTEXT_CLIENT_API_TOKEN" \ + "$POWERCONTEXT_URL/v1/capabilities" \ + | jq . +``` + +Python 示例会在设置 `POWERCONTEXT_CLIENT_API_TOKEN` 后自动发送该 header。不要把 token 放进 URL、Memory、Source、 +日志或模型 prompt。允许远程访问前，应在可信网关终止 TLS，并在那里执行身份验证、scope 授权、限流和审计。 + +## 14. 处理错误 + +错误响应使用稳定 envelope： + +```json +{ + "error": { + "code": "invalid_request", + "message": "The request violates the API contract.", + "details": {} + } +} +``` + +每个响应都包含 `X-PowerContext-Request-ID`。生产客户端应记录状态码、稳定的 `error.code` 和 request ID，不要依赖 +内部异常文本。 + +| 状态码 | 常见原因 | 应用处理 | +| --- | --- | --- | +| `401` | 缺少或使用了无效 Bearer token | 不重试；修复凭据 | +| `404` | citation 指向的不可变值不存在 | 重新读取列表或搜索结果 | +| `409` | 使用了过期 citation 或发生不可变状态冲突 | 重新读取最新 entry，让用户重新决定 | +| `422` | 字段缺失、超长、为空或类型错误 | 修复客户端输入，不盲目重试 | +| `503` | 必需 Runtime 绑定或依赖不可用 | 读取路径可降级；写路径报告失败并稍后重试 | +| `500` | Server 内部错误 | 记录 request ID，有限退避重试 | + +网络超时也应有限重试。不要自动重试一次非幂等写入直到确认前一次请求是否已经成功；可先按业务键搜索或使用明确 +的幂等 Source `source_id`。 + +## 15. 上线检查清单 + +- [ ] `scope_id` 来自可信的用户、租户或项目映射，不接受模型任意指定； +- [ ] Gateway 对每个调用者执行 scope 授权，因为 `scope_id` 本身不是 ACL； +- [ ] 每个模型请求最多调用一次 `/v1/context/prepare`； +- [ ] `PreparedContext` 保持只读、不可信，当前指令和实时数据优先； +- [ ] prepare

Revise incorrect Memory - -Memory entries are not overwritten in place. A revision creates a new version and preserves history. Use the exact -citation from step 4: - -```bash -jq --arg scope "$POWERCONTEXT_SCOPE" \ - --arg text 'For billing questions, explain the charges; offer refunds only when the refund policy allows it.' \ - '{ - scope_id: $scope, - citation: .entry.citation, - kind: "decision", - text: $text, - reason: "The support policy was clarified" - }' \ - /tmp/powercontext-remember.json \ - > /tmp/powercontext-revise.json - -curl --fail --silent --show-error \ - --request POST \ - --header 'Content-Type: application/json' \ - --data @/tmp/powercontext-revise.json \ - "$POWERCONTEXT_URL/v1/memory/entries/revise" \ - | tee /tmp/powercontext-revised.json \ - | jq . -``` - -The response's `entry.citation` identifies the new version. Use that new citation for every later revision or -retirement. Reusing the old citation returns `409`, preventing a concurrent request from overwriting newer content. - -## 10. Retire obsolete Memory - -Retirement does not physically delete history. Use the latest citation returned by the revision: - -```bash -jq --arg scope "$POWERCONTEXT_SCOPE" \ - '{ - scope_id: $scope, - citation: .entry.citation, - reason: "This support workflow has been discontinued" - }' \ - /tmp/powercontext-revised.json \ - > /tmp/powercontext-retire.json - -curl --fail --silent --show-error \ - --request POST \ - --header 'Content-Type: application/json' \ - --data @/tmp/powercontext-retire.json \ - "$POWERCONTEXT_URL/v1/memory/entries/retire" \ - | jq . -``` - -Normal search, list, and prepare operations stop using the entry. A list with `include_inactive: true` and an exact -get remain available for audit. - -## 11. Optional: preserve original Source evidence - -When you need to preserve a user confirmation, document excerpt, or business event as evidence for later processing, -call: - -```bash -curl --fail --silent --show-error \ - --request POST \ - --header 'Content-Type: application/json' \ - --data "$(jq -n \ - --arg scope "$POWERCONTEXT_SCOPE" \ - --arg source_id 'support-chat:session-7:turn-12' \ - --arg content 'The user confirmed: always explain the charges before discussing a billing resolution.' \ - '{ - scope_id: $scope, - source_id: $source_id, - content: $content, - metadata: {channel: "support-chat", consent: true} - }')" \ - "$POWERCONTEXT_URL/v1/sources/content" \ - | jq . -``` - -The Server returns `202 Accepted`. A `source_id` should consistently identify the same content so capture remains -idempotent. - -A Source is original evidence, not Memory. This endpoint does not call a model synchronously or make the content -immediately recallable. Automatic extraction requires a configured generation model and the Runtime flush or -scheduler flow; see the [full-capability Quick Start](../how-to/full-capability-runtime.md). - -Do not capture every conversation by default. Establish user consent, sensitive-field filtering, retention, and -purpose limits before preserving only the evidence you need. - -## 12. Verify cross-process persistence - -1. Stop the Server in terminal A. -2. Run `powercontext server run` again. -3. Repeat the search or list request from step 5. - -The active Memory remains available when the Server uses the same data directory and the application uses the same -`scope_id`. Do not confuse a container's temporary filesystem or a test database with production persistence. See -[Deploy the Server](../how-to/deploy-server.md) for a service deployment. - -## 13. Enable authentication or remote access - -The default loopback development setup may run without Server Bearer authentication. When authentication is enabled, -add this header to every request except health checks: - -```http -Authorization: Bearer -``` - -For example: - -```bash -export POWERCONTEXT_CLIENT_API_TOKEN='token loaded from a secure credential source' - -curl --fail --silent --show-error \ - --header "Authorization: Bearer $POWERCONTEXT_CLIENT_API_TOKEN" \ - "$POWERCONTEXT_URL/v1/capabilities" \ - | jq . -``` - -The Python example sends this header automatically when `POWERCONTEXT_CLIENT_API_TOKEN` is set. Never put a token in -a URL, Memory, Source, log, or model prompt. Before allowing remote access, terminate TLS at a trusted gateway and -enforce identity, scope authorization, rate limits, and audit there. - -## 14. Handle errors - -Error responses use a stable envelope: - -```json -{ - "error": { - "code": "invalid_request", - "message": "The request violates the API contract.", - "details": {} - } -} -``` - -Every response has an `X-PowerContext-Request-ID`. Production clients should record the status, stable `error.code`, -and request ID rather than depend on internal exception text. - -| Status | Common cause | Application behavior | -| --- | --- | --- | -| `401` | Missing or invalid Bearer token | Do not retry; fix credentials | -| `404` | The immutable value named by a citation does not exist | Refresh the list or search result | -| `409` | Stale citation or immutable-state conflict | Read the latest entry and ask for a new decision | -| `422` | Missing, oversized, blank, or mistyped field | Fix client input; do not retry blindly | -| `503` | A required Runtime binding or dependency is unavailable | Degrade reads; report failed writes and retry later | -| `500` | Internal Server error | Record the request ID and retry with bounded backoff | - -Use bounded retries for network timeouts as well. Do not repeatedly retry a non-idempotent write until you know -whether the previous request succeeded. Search by a business key first, or use a deliberately idempotent Source -`source_id` where that operation fits. - -## 15. Production checklist - -- [ ] Derive `scope_id` from a trusted user, tenant, or project mapping; never let the model choose it freely. -- [ ] Authorize every caller for its scope at the Gateway because `scope_id` is not an ACL. -- [ ] Call `/v1/context/prepare` no more than once per model request. -- [ ] Keep `PreparedContext` read-only and untrusted; current instructions and live data take precedence. -- [ ] A prepare timeout does not block the main model request; a write failure is never swallowed. -- [ ] The model can propose Memory, while auditable user or business authorization controls writes and mutations. -- [ ] Tokens, passwords, connection strings, private keys, and protected content never enter Memory, Source, prompts, - or logs. -- [ ] The client preserves exact citations and refreshes after `409` instead of overwriting. -- [ ] Configure connection, read, and total request timeouts and record `X-PowerContext-Request-ID`. -- [ ] Run the Server with persistent storage, backups, TLS, monitoring, and appropriate rate limits. -- [ ] When generating a client from `/openapi.json` or `openapi/powercontext.yaml`, pin and verify the contract version. - -Your AI application now uses long-term Memory over HTTP without depending on an Agent Host: it can save, recall, -inject, read exactly, revise, and retire Memory.

You will use PowerContext as an independent context +service and complete this HTTP API lifecycle: + +```text +Inspect the Server and capabilities + → capture Source evidence + → save, retrieve, and maintain Memory + → prepare context for each model request + → record Work, Handoff, and Task Outcome + → generate or propose an Experience Candidate from evidence + → Review creates an approved Experience + → incubate a managed Skill from Experience, Source, or usage + → Review, read, and use an exact Skill Revision + → operate the system with External Skill, Report, and Stats APIs +``` + +One self-built AI engineering assistant is used throughout the tutorial. The main path uses `curl` and JSON, requires +no Agent Host, and ends with a reusable Python integration boundary. + +## 1. Understand the product boundaries + +PowerContext does not automatically promote every record into a Skill. Each object has a distinct purpose and +authorization boundary: + +| Object | What it stores | How it is produced | When it is available | +| --- | --- | --- | --- | +| Source | Original evidence such as input, task results, and document excerpts | Persisted immediately on capture | Exact evidence; not recalled directly | +| Memory | Durable facts, decisions, preferences, and constraints | Explicit write or model-backed extraction from Source | Active entries can participate in search and `PreparedContext` | +| PreparedContext | Cited, bounded historical context for one request | Prepared ephemerally by the Runtime | One model request only; never persisted | +| Work/Handoff | Objective, verified state, omissions, and next action | Explicitly recorded, prepared, acknowledged, and committed | Transfers work across sessions, models, applications, or workers | +| Experience | What was done in a situation, the outcome, and the lesson | Complete proposal or generated Candidate followed by Review | The approved current Revision may participate in `PreparedContext` | +| managed Skill | What to do next time and how to validate it | Candidate from Experience, Source, or usage followed by Review | Exact read or explicit publication; never automatically in `PreparedContext` | +| external Skill | An Agent-native Skill package already on this host | Scan an explicitly configured local target | Resolvable only while fingerprint and local binding match | + +Three rules apply to every API family: + +1. `scope_id` partitions business data; it is not authorization. A Gateway must authorize the caller for the scope. +2. A Candidate is an untrusted proposal. A model cannot approve its own Candidate or commit the final Artifact. +3. An approved Skill is governed content, not permission to use files, networks, secrets, tools, or publication. + +## 2. Public API map + +The current OpenAPI contract exposes 53 public operations: + +| Domain | Path prefix | Operations covered here | +| --- | --- | --- | +| Health and capability | `/health/*`, `/v1/capabilities` | live, ready, capabilities | +| Source and Context | `/v1/sources/*`, `/v1/context/*` | capture, prepare | +| Work | `/v1/work/*` | contract, current Handoff, acknowledgement, outcome | +| Low-level Handoff | `/v1/handoff/*` | activate, prepare, finalize, commit, continue | +| Memory | `/v1/memory/*` | flush, remember, search, list, get, revise, retire, changes | +| Experience | `/v1/experience/*` | propose, generate, get | +| managed Skill | `/v1/skill/*` | propose, generate, get | +| Candidate Review | `/v1/artifact-candidates/*` | list, get, revise, approve, reject | +| External Skill | `/v1/external-skills/*` | scan, list, resolve, import/fork | +| Stats | `/v1/stats` | scoped inventory, model usage, recall estimates | +| Handoff Report | `/v1/handoff-reports/*` | Project, Workstream, Report, Activity, Workspace binding | + +This tutorial explains ordering and workflows. Use +[`openapi/powercontext.yaml`](https://github.com/oceanbase/powercontext/blob/master/openapi/powercontext.yaml) for every +field limit, enum, and response schema. + +## 3. Prepare the environment + +You need macOS or Linux, Python 3.11+, `uv`, `curl`, and `jq`: + +```bash +python3 --version +uv --version +curl --version +jq --version +``` + +Install the CLI and Server: + +```bash +uv tool install --force "powercontext[cli,server] @ git+https://github.com/oceanbase/powercontext.git@master" +``` + +Verify the installation: + +```bash +powercontext --version +powercontext server --help +``` + +Explicit Memory, Source, Work, Handoff, typed proposals, Review, and exact reads do not require a generation model. +`/experience/generate`, `/skill/generate`, external Skill import/fork, Source-to-Memory extraction, and vector behavior +require their configured providers. + +## 4. Start the Server + +Keep this running in **terminal A**: + +```bash +powercontext server run +``` + +The default address is `http://127.0.0.1:8000`. Data is persisted in the SQLite database under the PowerContext user +data directory. + +Set tutorial variables in **terminal B**: + +```bash +export POWERCONTEXT_URL=http://127.0.0.1:8000 +export POWERCONTEXT_SCOPE=tenant:demo:project:api-tutorial +``` + +Do not use a session ID that changes on every conversation. Source, Memory, Experience, Skill, and Handoff for one +project must reuse the same stable scope. + +## 5. Inspect health, capabilities, and the contract + +```bash +curl --fail --silent --show-error "$POWERCONTEXT_URL/health/live" | jq . +curl --fail --silent --show-error "$POWERCONTEXT_URL/health/ready" | jq . +curl --fail --silent --show-error "$POWERCONTEXT_URL/v1/capabilities" | jq . +``` + +Success criteria: + +- liveness returns `200`; +- readiness returns `200` with `ready`, or `degraded` when the required base runtime remains usable; +- capabilities lists `artifact_families`, search modes, and generation switches. + +The running process exposes: + +- `/docs` for Swagger UI; +- `/redoc` for ReDoc; +- `/openapi.json` for the exact runtime OpenAPI JSON. + +## 6. Authentication and common request rules + +The default loopback development setup may run without Bearer authentication, so the main commands omit an +`Authorization` header. When authentication is enabled, add this to every request except health checks: + +```http +Authorization: Bearer +``` + +For example: + +```bash +export POWERCONTEXT_CLIENT_API_TOKEN='token loaded from a secure credential source' + +curl --fail --silent --show-error \ + --header "Authorization: Bearer $POWERCONTEXT_CLIENT_API_TOKEN" \ + "$POWERCONTEXT_URL/v1/capabilities" \ + | jq . +``` + +Never place a token in a URL, Memory, Source, model prompt, or log. Before remote access, terminate TLS at a trusted +Gateway or Service Mesh and enforce identity, scope authorization, rate limits, and audit there. + +Every response includes `X-PowerContext-Request-ID`. To inspect headers and body together: + +```bash +curl --silent --show-error \ + --dump-header /tmp/powercontext-headers.txt \ + "$POWERCONTEXT_URL/v1/capabilities" \ + | jq . + +grep -i '^X-PowerContext-Request-ID:' /tmp/powercontext-headers.txt +``` + +## 7.

-## 1. 先理解三个边界 - -### `scope_id` 是数据分区，不是权限 - -同一个用户、项目或业务空间的所有 Memory 请求必须使用稳定的 `scope_id`。例如： - -```text -tenant:acme:user:42 -``` - -不要使用每次都会变化的会话 ID。`scope_id` 只告诉 PowerContext 去哪个分区读写数据，不会证明调用者有权访问该 -分区。生产环境必须由你的认证层、API Gateway 或 Service Mesh 验证调用者，并将调用者映射到允许访问的 scope。 - -### `PreparedContext` 是不可信历史数据 - -`POST /v1/context/prepare` 返回的是带 citation、有字节上限、只在本次请求中使用的历史上下文。它不是当前用户 -指令，也不能覆盖 system/developer 指令、仓库规则或实时验证结果。PowerContext 返回的 `content` 已包含信任边界 -说明；应用应保持原文，不要把它改写成更高优先级的指令。 - -### 读取可以降级，写入必须明确 - -如果准备上下文暂时失败，AI 应用通常可以在没有历史上下文的情况下继续回答，并记录请求 ID 以便排查。写入、 -修订或停用失败时，不应伪装成成功。除非产品已经有明确、可审计的写入策略，否则让用户确认后再保存长期 Memory。 - -## 2. 准备环境 - -需要： - -- macOS 或 Linux； -- Python 3.11 或更高版本； -- [`uv`](https://docs.astral.sh/uv/)； -- `curl`； -- `jq`，用于查看响应和复用精确 citation。 - -检查本地工具： - -```bash -python3 --version -uv --version -curl --version -jq --version -``` - -安装 PowerContext CLI 和 Server： - -```bash -uv tool install --force "powercontext[cli,server] @ git+https://github.com/oceanbase/powercontext.git@master" -``` - -确认安装成功： - -```bash -powercontext --version -powercontext server --help -``` - -## 3. 启动并检查 Server - -准备两个终端。在**终端 A**持续运行： - -```bash -powercontext server run -``` - -默认 Server 监听 `http://127.0.0.1:8000`，并使用本机 PowerContext 数据目录中的 SQLite 数据库持久化数据。 - -在**终端 B**设置本教程使用的变量： - -```bash -export POWERCONTEXT_URL=http://127.0.0.1:8000 -export POWERCONTEXT_SCOPE=tenant:demo:user:42 -``` - -检查进程与 Runtime： - -```bash -curl --fail --silent --show-error "$POWERCONTEXT_URL/health/live" | jq . -curl --fail --silent --show-error "$POWERCONTEXT_URL/health/ready" | jq . -curl --fail --silent --show-error "$POWERCONTEXT_URL/v1/capabilities" | jq . -``` - -**成功标准：** liveness 请求返回 `200`；readiness 返回 `200`，且状态不是 `not_ready`；capabilities 能列出当前 -Runtime 能力。显式 Memory 即使没有 generation model 也可以工作；模型抽取和向量检索属于可选能力。 - -## 4. 保存第一条显式 Memory - -先保存一条已经由用户或业务规则确认的长期信息： - -```bash -curl --fail --silent --show-error \ - --request POST \ - --header 'Content-Type: application/json' \ - --data "$(jq -n \ - --arg scope "$POWERCONTEXT_SCOPE" \ - --arg kind decision \ - --arg text '回答账单问题时，先解释费用构成，再提供退款入口。' \ - --arg reason '用户确认的客服策略' \ - '{scope_id: $scope, kind: $kind, text: $text, reason: $reason}')" \ - "$POWERCONTEXT_URL/v1/memory/remember" \ - | tee /tmp/powercontext-remember.json \ - | jq . -``` - -响应结构类似下面这样。ID 由 Server 生成，每次运行都会不同： - -```json -{ - "memory": { - "family": "memory", - "artifact_id": "memory-example", - "revision": 1 - }, - "entry": { - "citation": { - "memory_ref": { - "family": "memory", - "artifact_id": "memory-example", - "revision": 1 - }, - "entry_id": "entry-example", - "entry_version_id": "entry-version-example" - }, - "version": 1, - "kind": "decision", - "text": "回答账单问题时，先解释费用构成，再提供退款入口。", - "state": "active", - "source_refs": [], - "artifact_refs": [] - } -} -``` - -`memory.revision` 表示这次写入后的 Memory Revision。`entry.citation` 精确指向一个不可变条目版本；读取、修订和 -停用都要传回完整 citation，不能只保存 `entry_id`。 - -`remember` 只保存已经整理好的 Memory，不会创建 Source，也不会调用 generation model。需要保留原始证据时， -使用第 11 步的 Source 接口。 - -## 5. 搜索、列出和精确读取 Memory - -### 搜索与当前问题相关的条目 - -```bash -curl --fail --silent --show-error \ - --request POST \ - --header 'Content-Type: application/json' \ - --data "$(jq -n \ - --arg scope "$POWERCONTEXT_SCOPE" \ - --arg query '用户问账单和退款时应该怎么回答？' \ - '{scope_id: $scope, query: $query, limit: 5, mode: "auto"}')" \ - "$POWERCONTEXT_URL/v1/memory/search" \ - | jq . -``` - -响应中的 `hits` 只包含 active 条目。每个 hit 都有 `citation`、`text`、`score` 和 `matched_by`。`mode: "auto"` -会使用当前 Runtime 可用的检索模式；没有匹配项时正常返回 `"hits": []`，不是错误。 - -### 列出当前 Memory head - -```bash -curl --fail --silent --show-error \ - --request POST \ - --header 'Content-Type: application/json' \ - --data "$(jq -n --arg scope "$POWERCONTEXT_SCOPE" '{scope_id: $scope}')" \ - "$POWERCONTEXT_URL/v1/memory/entries/list" \ - | jq . -``` - -审计时可以增加 `"include_inactive": true`，查看当前 head 中已停用的条目。默认不会返回它们。 - -### 按精确 citation 读取 - -下面的命令从第 4 步保存的响应构造请求： - -```bash -jq --arg scope "$POWERCONTEXT_SCOPE" \ - '{scope_id: $scope, citation: .entry.citation}' \ - /tmp/powercontext-remember.json \ - > /tmp/powercontext-get.json - -curl --fail --silent --show-error \ - --request POST \ - --header 'Content-Type: application/json' \ - --data @/tmp/powercontext-get.json \ - "$POWERCONTEXT_URL/v1/memory/entries/get" \ - | jq . -``` - -精确读取返回 citation 指向的不可变版本，即使以后该条目已经被修订或停用，也不会悄悄换成另一个版本。 - -## 6. 在每次模型请求前准备上下文 - -应用收到用户问题后，调用一次 `POST /v1/context/prepare`： - -```bash -curl --fail --silent --show-error \ - --request POST \ - --header 'Content-Type: application/json' \ - --data "$(jq -n \ - --arg scope "$POWERCONTEXT_SCOPE" \ - --arg query '我的账单为什么这么高？如果不认可可以退款吗？' \ - '{scope_id: $scope, query: $query, max_bytes: 4000}')" \ - "$POWERCONTEXT_URL/v1/context/prepare" \ - | tee /tmp/powercontext-prepared.json \ - | jq . -``` - -有相关内容时，响应为： - -```json -{ - "schema": "powercontext.prepared-context.v1", - "status": "ready", - "content": "BEGIN_POWERCONTEXT_PREPARED_CONTEXT_V1\n…\nEND_POWERCONTEXT_PREPARED_CONTEXT_V1", - "content_bytes": 987 -} -``` - -没有可用内容时，这是正常结果： - -```json -{ - "schema": "powercontext.prepared-context.v1", - "status": "empty", - "content": null, - "content_bytes": 0 -} -``` - -应用只在 `status == "ready"` 且 `content` 为字符串时注入。不要把 `PreparedContext` 再写回 Memory；它是本次 -请求的临时组合结果，不是新的事实。 - -## 7. 接入现有 AI 调用代码 - -下面使用 Python 标准库完成 PowerContext 请求，并把模型调用留在一个明确的适配函数中。这样可以继续使用你已经 -选定的模型 SDK，而不会让 Memory 层绑定某一家模型服务。 - -```python -from __future__ import annotations - -import json -import os -from collections.abc import Callable -from typing import Any -from urllib.error import HTTPError, URLError -from urllib.request import Request, urlopen - -POWERCONTEXT_URL = os.environ.get("POWERCONTEXT_URL", "http://127.0.0.1:8000") -POWERCONTEXT_SCOPE = os.environ["POWERCONTEXT_SCOPE"] -POWERCONTEXT_TOKEN = os.environ.get("POWERCONTEXT_CLIENT_API_TOKEN") -

}, - ) - except (HTTPError, URLError, TimeoutError): - # 读取失败可以降级：记录错误和 request ID，然后让主模型请求继续。 - return None - - if prepared.get("status") != "ready": - return None - content = prepared.get("content") - return content if isinstance(content, str) else None - - -def ask_ai( - user_query: str, - call_your_model: Callable[[list[dict[str, str]]], str], -) -> str: - messages = [ - { - "role": "system", - "content": "Follow current application policy and the user's current request.", - } - ] - - context = prepare_context(user_query) - if context is not None: - # 如果模型 API 有低权限的 context/tool-result 通道，优先使用它。 - # 使用 messages API 时，不要把历史内容升级成 system/developer 指令。 - messages.append({"role": "user", "content": f"Historical reference data:\n{context}"}) - - messages.append({"role": "user", "content": user_query}) - return call_your_model(messages) -``` - -把你现有的模型调用封装成 `call_your_model(messages) -> str`，然后调用： - -```python -answer = ask_ai("我的账单为什么这么高？", call_your_model) -``` - -关键约束： - -- 一个用户请求只调用一次 `prepare`，不要先 search 再让 `prepare` 重复检索； -- 保留 PowerContext 返回的 `content`，让其中的 citation 与信任说明保持完整； -- 当前用户请求和实时业务数据始终高于历史 Memory； -- 上下文读取可以 fail open，写操作不能静默失败； -- 不要把 PowerContext token、数据库连接串或内部身份信息交给模型。 - -## 8. 让模型通过工具主动查找或建议 Memory - -如果模型支持 function/tool calling，可以把你自己的包装函数暴露给模型，但不要让模型直接持有 Server token 或 -任意填写 `scope_id`。应用应从已认证会话注入这两个值。 - -建议只暴露下面三类工具： - -| 模型工具 | PowerContext API | 调用策略 | -| --- | --- | --- | -| `search_project_memory(query, limit)` | `POST /v1/memory/search` | 可自动调用；限制 query 长度和 limit | -| `get_memory(citation)` | `POST /v1/memory/entries/get` | 可自动调用；citation 必须来自同一 scope 的响应 | -| `propose_memory(kind, text, reason)` | 经用户确认后调用 `POST /v1/memory/remember` | 模型只能提出建议，应用负责确认和写入 | - -包装函数示例： - -```python -def search_project_memory(query: str, limit: int = 5) -> dict[str, Any]: - return powercontext_post( - "/v1/memory/search", - { - "scope_id": POWERCONTEXT_SCOPE, - "query": query[:8192], - "limit": max(1, min(limit, 50)), - "mode": "auto", - }, - ) - - -def remember_after_approval(kind: str, text: str, reason: str) -> dict[str, Any]: - # 在进入这个函数之前，由 UI 或业务规则产生可审计的批准结果。 - return powercontext_post( - "/v1/memory/remember", - { - "scope_id": POWERCONTEXT_SCOPE, - "kind": kind[:128], - "text": text, - "reason": reason[:512], - }, - ) -``` - -不要把“模型调用了 `propose_memory`”本身当作授权。应用可以先在 UI 中显示建议内容，让用户选择保存、编辑或忽略。 -也不要保存模型的整段回答；长期 Memory 应是短小、明确、以后仍然成立的决定、偏好、约束、状态或下一步。 - -## 9. 修订错误 Memory - -Memory 条目不会原地覆盖。修订会创建新版本并保留历史。下面使用第 4 步的精确 citation： - -```bash -jq --arg scope "$POWERCONTEXT_SCOPE" \ - --arg text '回答账单问题时，先解释费用构成；只有符合退款政策时才提供退款入口。' \ - '{ - scope_id: $scope, - citation: .entry.citation, - kind: "decision", - text: $text, - reason: "客服政策已澄清" - }' \ - /tmp/powercontext-remember.json \ - > /tmp/powercontext-revise.json - -curl --fail --silent --show-error \ - --request POST \ - --header 'Content-Type: application/json' \ - --data @/tmp/powercontext-revise.json \ - "$POWERCONTEXT_URL/v1/memory/entries/revise" \ - | tee /tmp/powercontext-revised.json \ - | jq . -``` - -响应中的 `entry.citation` 指向新版本。后续修订或停用必须使用这个新 citation；继续使用旧 citation 会收到 `409` -冲突，防止并发请求覆盖更新后的内容。 - -## 10. 停用过期 Memory - -停用不会物理删除历史。下面使用修订响应中的最新 citation： - -```bash -jq --arg scope "$POWERCONTEXT_SCOPE" \ - '{ - scope_id: $scope, - citation: .entry.citation, - reason: "该客服流程已经下线" - }' \ - /tmp/powercontext-revised.json \ - > /tmp/powercontext-retire.json - -curl --fail --silent --show-error \ - --request POST \ - --header 'Content-Type: application/json' \ - --data @/tmp/powercontext-retire.json \ - "$POWERCONTEXT_URL/v1/memory/entries/retire" \ - | jq . -``` - -停用后，普通 search、list 和 prepare 不再使用该条目；`include_inactive: true` 的 list 和精确 get 仍可用于审计。 - -## 11. 可选：保存原始 Source 证据 - -如果需要保留某次用户确认、文档片段或业务事件作为后续处理的证据，可以调用： - -```bash -curl --fail --silent --show-error \ - --request POST \ - --header 'Content-Type: application/json' \ - --data "$(jq -n \ - --arg scope "$POWERCONTEXT_SCOPE" \ - --arg source_id 'support-chat:session-7:turn-12' \ - --arg content '用户确认：以后账单回复必须先解释费用构成。' \ - '{ - scope_id: $scope, - source_id: $source_id, - content: $content, - metadata: {channel: "support-chat", consent: true} - }')" \ - "$POWERCONTEXT_URL/v1/sources/content" \ - | jq . -``` - -成功时返回 `202 Accepted`。同一个 `source_id` 应稳定指向同一份内容，以支持幂等采集。 - -Source 是原始证据，不等于 Memory。这个接口不会同步调用模型，也不会立即把内容变成可召回 Memory。需要自动抽取时， -必须另外配置 generation model，并使用 Runtime 的 flush 或 scheduler 流程；参见[完整功能 Quick Start](../how-to/full-capability-runtime.md)。 - -不要默认采集整段对话。先做用户同意、敏感字段过滤、保留期限和用途限制，再把必要证据写入 Source。 - -## 12. 验证跨进程持久化 - -1. 停止终端 A 中的 Server； -2. 再次运行 `powercontext server run`； -3. 重复第 5 步的 search 或 list 请求。 - -只要使用同一数据目录和同一 `scope_id`，之前保存的 active Memory 仍然存在。不要把容器临时文件系统或测试数据库 -误当作生产持久化；服务化部署参见[部署 Server](../how-to/deploy-server.md)。 - -## 13. 启用鉴权或远程访问 - -默认 loopback 开发环境可以不启用 Server Bearer 鉴权。启用后，在除 health 之外的每个请求中增加： - -```http -Authorization: Bearer -``` - -例如： - -```bash -export POWERCONTEXT_CLIENT_API_TOKEN='从安全凭据源读取的 token' - -curl --fail --silent --show-error \ - --header "Authorization: Bearer $POWERCONTEXT_CLIENT_API_TOKEN" \ - "$POWERCONTEXT_URL/v1/capabilities" \ - | jq . -``` - -Python 示例会在设置 `POWERCONTEXT_CLIENT_API_TOKEN` 后自动发送该 header。不要把 token 放进 URL、Memory、Source、 -日志或模型 prompt。允许远程访问前，应在可信网关终止 TLS，并在那里执行身份验证、scope 授权、限流和审计。 - -## 14. 处理错误 - -错误响应使用稳定 envelope： - -```json -{ - "error": { - "code": "invalid_request", - "message": "The request violates the API contract.", - "details": {} - } -} -``` - -每个响应都包含 `X-PowerContext-Request-ID`。生产客户端应记录状态码、稳定的 `error.code` 和 request ID，不要依赖 -内部异常文本。 - -| 状态码 | 常见原因 | 应用处理 | -| --- | --- | --- | -| `401` | 缺少或使用了无效 Bearer token | 不重试；修复凭据 | -| `404` | citation 指向的不可变值不存在 | 重新读取列表或搜索结果 | -| `409` | 使用了过期 citation 或发生不可变状态冲突 | 重新读取最新 entry，让用户重新决定 | -| `422` | 字段缺失、超长、为空或类型错误 | 修复客户端输入，不盲目重试 | -| `503` | 必需 Runtime 绑定或依赖不可用 | 读取路径可降级；写路径报告失败并稍后重试 | -| `500` | Server 内部错误 | 记录 request ID，有限退避重试 | -

"status": "empty", - "content": null, - "content_bytes": 0 -} -``` - -`content` 是临时、只读、不可信历史数据。保持其中的 trust notice 和 citation，不要把它写回 Memory，也不要让它 -覆盖当前 system/developer 指令、用户请求、实时业务数据或现场验证。 - -## 12. 接入自己的 AI 模型 - -下面的 Python 标准库代码封装 PowerContext；你只需把现有模型 SDK 接入 `call_your_model`： +在应用中创建 `powercontext_example.py`。这个例子只使用 Python 标准库。 ```python from __future__ import annotations import json import os -from collections.abc import Callable from typing import Any -from urllib.error import HTTPError, URLError +from urllib.error import HTTPError from urllib.request import Request, urlopen -POWERCONTEXT_URL = os.environ.get("POWERCONTEXT_URL", "http://127.0.0.1:8000") -POWERCONTEXT_SCOPE = os.environ["POWERCONTEXT_SCOPE"] -POWERCONTEXT_TOKEN = os.environ.get("POWERCONTEXT_CLIENT_API_TOKEN") +BASE_URL = os.environ.get("POWERCONTEXT_URL", "http://127.0.0.1:8000").rstrip("/") +SCOPE_ID = os.environ.get("POWERCONTEXT_SCOPE", "project:billing-assistant") +TOKEN = os.environ.get("POWERCONTEXT_TOKEN") -def powercontext_post(path: str, payload: dict[str, Any]) -> dict[str, Any]: + +def post(path: str, payload: dict[str, Any]) -> dict[str, Any]: headers = {"Content-Type": "application/json"} -
