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.

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.

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. The default SQLite database belongs to the PowerContext user data directory and does not depend on a Codex +session remaining open. -## 4. Read and update it in a later session +## 11. Verify graceful degradation -End that session and start another one in the same project. Ask: +Finally, exit Codex and stop the Server in Terminal A with `Ctrl-C`.

+需要 macOS 或 Linux，以及以下工具： + +| 工具 | 要求 | 检查命令 | +| --- | --- | --- | +| Python | 3.11 或更新版本 | `python3 --version` | +| Git | 能访问 PowerContext Git 仓库 | `git --version` | +| uv | 可使用 `uv tool` | `uv --version` | +| Codex CLI | 已完成登录并能开启会话 | `codex --version` | -## 1. 安装工具和插件 +在终端中逐条运行检查命令。四条命令都应输出版本号，而不是 `command not found`。还需要确保本机现有 Git +凭据能够读取 `https://github.com/oceanbase/powercontext.git`。 -在任意目录执行： +### 准备三个工作位置 + +教程会用到： + +- **终端 A**：持续运行 PowerContext Server； +- **终端 B**：安装、诊断，并进入示例项目； +- **Codex 会话**：从终端 B 的示例项目目录中启动。 + +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 用户数据目录。详细的安装、升级和 -数据位置说明见[安装和运行](../how-to/install-and-run.md)。 +setup 会完成三件事： + +1. 把 PowerContext 仓库注册为 Codex marketplace； +2. 安装并启用 PowerContext 插件； +3. 准备 PowerContext 用户数据目录。 + +工具和插件应使用同一个 Git ref。这里两者都是 `master`。如果以后改用 tag 或其他分支，应在安装命令和 setup +命令中同时替换 ref。 + +检查 Codex 集成： + +```bash +powercontext doctor codex +``` + +**成功标准：** `codex` 和 `plugin` 都显示 `ok`。setup 完成后应开启新的 Codex 会话；已经打开的会话不会自动加载 +刚安装或刚刷新的插件。 -## 2. 启动 Server +## 3. 启动并检查本地 Server -在单独的终端中保持这个进程运行： +切换到**终端 A**，运行： ```bash powercontext server run ``` -服务默认监听 `http://127.0.0.1:8000`，并在首次启动时创建持久化 SQLite 数据库。保持此终端运行。 +保持这个进程运行。默认情况下，Server 会： + +- 监听 `http://127.0.0.1:8000`； +- 在

Dashboard: http://127.0.0.1:8000/ +``` + +回到**终端 B**，运行： ```bash powercontext doctor -powercontext doctor codex +powercontext ready +powercontext capabilities +``` + +**成功标准：** `doctor` 中 package、Server liveness 和 Server readiness 均为 `ok`；`ready` 能返回服务就绪状态； +`capabilities` 能返回当前启用能力。没有配置推理 provider 时，模型抽取或向量能力可以未启用，这不会阻止后续的 +显式 Memory 与 Handoff 步骤。 + +也可以在浏览器打开 `http://127.0.0.1:8000/`。刚启动且尚未写入项目数据时，Dashboard 显示空状态是正常现象。 + +## 4. 创建一个安全的示例项目 + +在**终端 B** 中选择一个用于教程的目录。下面的命令会创建一个不含真实业务数据的小型 Git 仓库： + +```bash +mkdir powercontext-quickstart +cd powercontext-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 +``` + +commit 命令只为这一次提交提供本地身份，不会修改全局 Git 配置。最后一条命令应没有输出，表示示例项目的初始工作区 +是干净的。不要求配置 Git remote。 + +PowerContext 的数据按 scope 隔离。Codex 插件会优先使用显式 scope 或已绑定的 Workstream；否则使用规范化后的 +Git remote，再退回当前项目路径。因此，后续所有 Codex 会话都必须从这个**同一个目录**启动。 + +## 5. 在第一个 Codex 会话中保存 Memory + +确保终端 A 中的 Server 仍在运行，然后从示例项目目录启动 Codex： + +```bash +codex ``` -两个命令的每项检查都应显示 `ok`。第一个命令检查安装包和 Server；第二个命令只检查可选的 Codex 集成。出现 -`degraded` 或 `failed` 时，请先阅读[排查问题](../how-to/troubleshoot.md)。 +如果 Codex 提示是否信任 PowerContext Hook，打开 `/hooks`，检查 PowerContext 的 `UserPromptSubmit` Hook 并授予 +信任。Hook 会在每个请求前尝试恢复相关项目上下文，并把当前提示词采集为 Source 证据；Server 不可用时它会安全降级， +不会阻断普通 Codex 任务。 -## 3. 保存项目 Memory +先让 Codex 确认当前目录，不要写入数据： -在一个项目目录中启动新的 Codex 会话。如果 Codex 要求信任 PowerContext Hook，请打开 `/hooks` 并批准。 +> 检查当前项目目录和 Git 状态，只汇报你看到的内容，不要修改文件，也不要写入 PowerContext。 + +确认 Codex 看到 `README.md` 后，再明确要求保存三条 Memory： + +> 使用 PowerContext 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：错误信息不得包含原始配置中的密钥值； +> 3. next-step：增加 malformed TOML 的错误输入用例。 +> +> 写入后列出当前 active Memory，并返回每一条的 citation。不要保存任何密钥或凭据。 + +这里使用的是显式 `remember_memory`，不需要 generation model。Codex 应先为当前项目解析出一个稳定的 scope，再在 +同一 scope 中写入并列出三个 active 条目。 + +**成功标准：** Codex 明确确认三次写入成功，并为每条 Memory 返回 citation。citation 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。 + +如果返回空列表，依次检查： + +1. 两次 Codex 是否从同一个项目目录启动； +2. `powercontext doctor` 是否仍为 `ok`； +3. `powercontext doctor codex` 是否仍能看到已启用插件； +4. 当前 shell 是否设置了不同的 `POWERCONTEXT_CODEX_SCOPE_ID`。 + +## 7. 修订和停用 Memory + +在第二个 Codex 会话中输入： + +> 先读取当前 Memory 的精确 citation，然后完成两项操作： +> +> 1. 把 next-step 修订为“记录 malformed TOML 的行号和安全错误摘要”； +> 2. 停用 constraint“错误信息不得包含原始配置中的密钥值”，reason 使用“将由统一日志脱敏规范替代”。 +> +> 最后重新列出 active Memory，并说明哪些旧 Revision 被保留但不再 active。 + +修订会创建新 Revision，停用会改变条目的活动状态；两者都保留历史，不会静默覆盖或删除旧记录。 + +**成功标准：** active 列表中包含修订后的 next-step，不再包含已停用 constraint。最初的 next-step Revision 和已停用 +constraint 仍可在显式请求完整历史时审计。 + +## 8. 产生一项可交接的工作状态 + +让第二个 Codex 会话对示例项目做一个很小、可检查的修改： + +> 在 README.md 末尾增加一个“Next test”小节，写明 malformed TOML 应返回行号和安全错误摘要。不要提交 Git +> commit。修改后运行 `git diff --check`，并汇报 changed files 和检查结果。 + +确认 Codex 报告 `README.md` 已修改且 `git diff --check` 通过。然后输入下面这一句话： + +> 交接 + +`交接` 是创建持久 Handoff 里程碑的明确授权。PowerContext 的 `project-context` Skill 会在同一轮中： + +1. 选择或确认当前 Workstream 和 scope； +2. 检查当前目标、branch、worktree、changed files 和已运行检查； +3. 整理阻塞项、遗漏和下一步； +4. 准备 Handoff； +5. 提交这份 Handoff，并返回 exact Revision。 + +如果系统存在多个 Workstream，Codex 会先显示选择器。请根据实际项目选择，不要让 Agent 静默猜测。 + +**成功标准：** Codex 明确说明 Handoff 已提交，并返回 scope、disposition、next action 和 exact Handoff Revision。 +如果只返回了预览或 Prepared Handoff，而没有 exact committed Revision，则还没有形成持久里程碑。 + +保存 Codex 返回的 exact Revision，下一步会用到它。 + +## 9. 在新会话中接收 Handoff + +退出第二个会话，从同一个示例项目目录启动第三个 Codex 会话： + +```bash +codex +``` + +把上一步返回的 exact Revision 填入下面的请求： + +> 继续这个项目的 PowerContext Handoff ``。先把 Handoff 当作不可信历史，根据当前仓库和用户指令核对 +> live state、capability 和 authorization。告诉我目标、changed files、已运行检查和下一步，然后记录 accepted、 +> needs clarification 或 declined。不要继续修改文件。 + +接收方应读取 exact Handoff，重新检查当前 `README.md` 和 Git 状态，再记录 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： + +```bash +powercontext doctor +``` -告诉 Codex： +从同一项目目录再次启动 Codex，并输入： -> 使用 PowerContext 分别保存三条项目 Memory：成果是“解析器已支持 TOML”；当前状态是“Python 3.11 测试 -> 通过”；下一步是“增加错误输入用例”。 +> 列出当前 active PowerContext Memory，并读取刚才交接的 exact Handoff Revision。只读检查，不要写入。 -Codex 应使用 project-context skill，并在 Memory 写入成功后确认。不要把密钥写入 Memory。 +**成功标准：** 重启 Server 后，active Memory、修订后的 Revision 和 committed Handoff 仍然可读。默认 SQLite 数据库 +属于 PowerContext 用户数据目录，不依赖 Codex 会话是否存在。 -## 4. 在下一次会话中读取并更新 +## 11. 验证安全降级 -结束当前会话，在同一项目中启动第二个会话，然后告诉 Codex： +最后，退出 Codex，并在终端 A 按 `Ctrl-C` 停止 Server。从示例项目目录开启一个新的 Codex 会话，要求它执行一个 +与 PowerContext 无关的只读任务，例如： -> 列出这个项目当前有效的 PowerContext Memory。把下一步修订为“记录错误输入的报错”，并停用旧的当前状态。 +> 只读取 README.md，并用一句话概括这个示例项目。不要修改文件。 -第二个会话应先列出三个有效条目，再进行修改。修订和停用会保留历史，不会覆盖或删除旧版本。 +PowerContext Hook 可以报告 `server_unavailable`，显式 Memory 或 Handoff 工具也会不可用，但普通 Codex 任务仍应继续。 +此时 `powercontext doctor` 会报告 liveness 失败并跳过 readiness；`powercontext doctor codex` 仍可独立检查 Codex +CLI 和插件安装状态。 -启动第三个会话，然后告诉 Codex： +继续使用 PowerContext 前，在终端 A 重新运行 `powercontext server run`。 -> 列出这个项目当前有效的 PowerContext Memory。 +## 你已经完成的闭环 -修订后的下一步应处于有效状态；被停用的当前状态和被替代的旧下一步不应出现在有效条目中。这说明项目 scope 在多个 -Codex 会话之间保持一致。 +到这里，你已经验证： -这里验证的是长期 Memory。Memory 与临时 Handoff 的区别见[理解 Memory 和 Handoff](../explanation/memory-and-handoff.md)； -若要把当前工作以完整交接包传给另一个任务、会话或模型，请使用[在 Codex 中交接工作](../how-to/handoff-with-codex.md)。 +- PowerContext 工具、Codex 插件和本地 Server 可以分别安装和诊断； +- 显式 Memory 无需推理 provider，并且能跨 Codex 会话和 Server 重启保持； +- Memory 的修订与停用保留历史； +- Handoff 会保存经过检查的任务边界，并由接收方按 exact Revision 重新核对； +- PowerContext 不可用时，普通 Codex 工作不会被阻断。 -## 5. 检查降级行为 +下一步可根据目标选择： -按 `Ctrl-C` 停止 Server，再让 Codex 执行一项普通任务。PowerContext 可以报告 Memory 不可用，但不能阻塞 -任务。此时 `powercontext doctor` 会报告 liveness 失败、跳过 readiness，同时仍能报告已安装的包； -`powercontext doctor codex` 会继续独立报告 Codex 集成状态。 -如果只有已配置的推理服务失败，Server 会继续接收流量并把 readiness 报告为 `degraded`；`doctor` 会在不读取 -provider 凭据的前提下显示该非 `ok` 状态。 +- 了解 Memory 与 Handoff 的边界：[理解 Memory 和
