From c02b2fe8e4a59058f1b93ea8c65e28b8bffceb39 Mon Sep 17 00:00:00 2001 From: Kyle Mistele Date: Tue, 6 Oct 2026 18:16:42 -0700 Subject: [PATCH 01/20] feat(delivery): execute callback sequences in order across backends Persist callback progress and isolate each step's delivery identity so completed callbacks are not repeated on retries. Run GitHub creation before mention or subscription continuation, waiting for handoffs and output to settle before advancing. Update all providers and storage backends with lifecycle contract coverage, and expose ready-to-use Cloudflare fetch handlers.

Deny other mentions with thumbs down and one bot-authored maintainer-only notice per issue or pull request, returning before authorized handlers run. Exercise the registered mention handler, remove obsolete author-access and fake-agent code, and simplify the GitHub-only Worker setup.

The libraries do not enforce this application policy. -- **GitHub requires write access.** Anyone can comment on a public repository, so every GitHub callback looks up the author's access to the repository with `fetchUserAccess(login)` before it acts. Authors below `write` (`none`, `read`, `triage`) are ignored: no comment, no reaction, and the log line `Example ignored GitHub author without write access` with their login and access level. In a subscribed batch the example acts only on new comments and review comments, so it checks each of those on its own and looks up each author once per batch; it does not look up the authors of events it does nothing with, such as check runs, whose sender is usually an app. If GitHub answers `not_found` (the login is not a user, such as a bot account), the author counts as `none` and the event is ignored and logged. Any other failed lookup fails the callback, which is retried like any other failure; the event never gets through unchecked. The bot's own events are dropped before any callback runs. -- **Slack ignores other workspaces.** In a Slack Connect channel, people from another workspace can mention the bot. Slack marks their messages with `user_team`, which `SlackMessage.authorTeamId` carries.

The webhook secret verifies incoming requests. The App ID and private key create short-lived installation tokens for API calls. The bot user ID prevents the app from responding to its own events. Secrets are not stored in mailbox admissions or Durable Object storage. +Optional Workers AI labeling settings (the defaults are shown): + +```dotenv +GITHUB_LABEL_MODEL=@cf/cloudflare/clef +GITHUB_LABEL_THRESHOLD=0.8 +GITHUB_LABEL_TIMEOUT="60 seconds" +``` + +`@cf/cloudflare/clef-flash` is also supported. Alchemy attaches a native binding named `AI` to the host Worker, and the mailbox's callbacks use it through the captured labeler service. No separate model API key is needed; inference uses the Cloudflare account's Workers AI service and incurs its normal usage charges. The pinned PR preview contains the Workers AI fix; main's unpublished Iceberg dependency currently prevents installing the main preview. + Restart `bun alchemy dev` after changing `.env`. For a deployed stack, deploy the updated secrets with: ```bash -bun alchemy deploy +bun run alchemy:deploy ``` ### 7. Test with a repository -Open an issue or pull request in an installed repository. The sample callback reads the discussion and its existing comments (and PR reviews), subscribes the discussion, posts a confirmation comment, and adds an `eyes` reaction to that comment. You can also invoke `@` in an issue body, PR body, issue comment, PR comment, or inline review comment. On every subscribed PR event batch, the example calls `pullRequest.listComments()` and `pullRequest.listReviewComments()`, then logs both current comment counts. Later subscribed comments and inline review comments receive an `eyes` reaction; all subscribed events are logged by the Durable Object. Completed-check callback events include both `headSha` and `checkRunId`, which can be passed to the check-run resource methods without accidentally inspecting a newer push. +After deployment, set the GitHub App's webhook URL to `https:///integrations/github/webhook`. Open a new issue describing a clear bug, then a new PR describing a documentation change. After the ten-second debounce and processing, Clef should add matching labels whose yes-probability meets the configured threshold. It considers only GitHub's nine default label names that already exist on this repository, can add multiple labels, and preserves existing labels. A null body is evaluated using the title. No confident matches means no label changes. Historical issues/PRs are not scanned automatically. + +Creation labeling does not require a maintainer mention. To test mention access separately, invoke `@` in an issue body, PR body, issue comment, PR comment, or inline review comment. Write access or higher gets eyes; other users get thumbs down and one maintainer-only notice per discussion. Creation labeling runs before a mention in the same opening batch. A failed labeling callback is logged and retried by mailbox processing; the later mention waits until that callback succeeds or the delivery terminates. + +Use Cloudflare Worker logs to look for `Workers AI label inference started`, `Workers AI label inference completed`, and `GitHub labels added`. Effect log annotations include repository, discussion number/type, model, threshold, candidate/selected labels, and probabilities. Creation callbacks also annotate the webhook event ID and delivery ID. Failures log `GitHub auto-label failed` with an error tag/reason; a missing runtime `AI` binding reports `binding_missing`. Request titles, bodies, credentials, and raw model responses are not logged. The `bot.github.auto_label` Effect span carries repository, number, and model attributes. This has been verified with a substituted native binding in tests, not live inference. In the GitHub App settings, **Advanced → Recent Deliveries** shows each webhook request, response status, and redelivery control. A successful admission returns HTTP 200. If GitHub reports 401, check the webhook secret. If callbacks fail with 403, check the app permissions and make sure the installation includes the repository. diff --git a/examples/alchemy-cloudflare/src/AutoLabel.ts b/examples/alchemy-cloudflare/src/AutoLabel.ts new file mode 100644 index 0000000..b1d677a --- /dev/null +++ b/examples/alchemy-cloudflare/src/AutoLabel.ts @@ -0,0 +1,175 @@ +import { GitHubApi, type GitHubApiError, type GitHubIssue, type GitHubPullRequest } from '@humanlayer/channels-github' +import * as Cloudflare from 'alchemy/Cloudflare' +import type { RuntimeContext } from 'alchemy/RuntimeContext' +import { Config, Context, Effect, Layer, Schema } from 'effect' + +const LabelModel = Schema.Literals(['@cf/cloudflare/clef', '@cf/cloudflare/clef-flash']) +const Probability = Schema.Finite.check(Schema.isBetween({ minimum: 0, maximum: 1 })) +const DecisionResponse = Schema.Struct({ + answers: Schema.Record(Schema.String, Schema.Struct({ type: Schema.Literal('noul'), noul: Probability })), +}) + +/** Only GitHub's default label names are eligible, and only when configured on the repository. */ +const labelPolicies = [ + { name: 'bug', id: 'bug', instructions: 'Does this report or fix unintended or broken software behavior?' }, + { name: 'documentation', id: 'documentation', instructions: 'Does this request or make documentation changes?' }, + { + name: 'enhancement', + id: 'enhancement', + instructions: 'Does this request or add new functionality or improve existing functionality?', + }, + { + name: 'question', + id: 'question', + instructions: 'Is this primarily a question asking for information or clarification?', + }, + { + name: 'duplicate', + id: 'duplicate', + instructions: + 'Does the supplied text explicitly identify this as a duplicate and reference the original issue or PR?

AgentSession saves the delivery in its Durable Object storage, runs the Fold turn in the background, and reports Working, then complete or fail, through the Worker's delivery API over a self service binding. A retried callback starts no second turn, and after a restart the saved delivery lets recovery finish the right one.

A batch that mentions the bot now runs onMentioned / onNewMention when it is configured; other batches in a subscribed discussion still run the subscribed-events callback. Linear already worked this way. Document the rule in the root and provider READMEs, and fix the example README's handler path and follow-up check.

Workers AI still labels new issues and pull requests. Each request starts with the discussion: the issue or pull request and everything said on it the first time, then only what is new since the agent's last turn, tracked by the highest comment, review, and line comment IDs it has seen. The bot's own comments and the comment that mentioned it are left out. Pull requests get tools for reviews and line comments, and the prompt asks the agent to answer questions quickly and plan longer work first. Tools that take no input used Schema.Struct({}), which accepts any value but null, so OpenAI rejected them. They now use an object schema with no fields.

Workers AI is still used to label new issues and pull requests. + GitHub App bot identities such as `my-reviewer[bot]` are not native mentionable accounts: GitHub does not autocomplete or link `@my-reviewer[bot]`. `GITHUB_BOT_MENTION_NAME` is instead the text invocation name recognized by this provider, without the leading `@`. Use the app slug for a natural command such as `@my-reviewer`. This can still render as plain text; use `[@my-reviewer](https://github.com/apps/my-reviewer)` when a clickable link is important. If the app slug matches a real user or organization, choose a distinct invocation name to avoid notifying that account. The GitHub provider reads these values while the Worker is constructed, so Alchemy binds them as Cloudflare secrets during deployment and its Durable Objects share the same bindings. The webhook secret verifies incoming requests. The App ID and private key create short-lived installation tokens for API calls. The bot user ID prevents the app from responding to its own events.

open pull requests from issues A pull request session now checks out the pull request's own branch, pulls it on every mention, and can push to it. A pull request from a fork, or whose branch was deleted, fails with a message saying why. An issue session gets github_create_pull_request, which opens a pull request from its branch into the default branch with "Closes #", or returns the one already open from that branch. The GitHub package adds the head repository to pull request info, and listPullRequestsForBranch and createPullRequest operations.

The comment and line comment tools return each comment's ID, author, link, and text, plus the file, line, diff, and thread for line comments, and the discussion context shows the same IDs. A mention in a line comment tells the agent where the comment is and which thread to reply in. The example README describes the GitHub agent: what happens on a mention, its branches, its tools, and what to look for in the logs.
