+# AI automation
+
+GitHub Actions orchestration that uses **Claude Code** with an Ollama Cloud
+Anthropic-compatible backend for issue triage and implementation of
+high-confidence bugs / small features. Isolated research uses the Brave Search
+API. Own / bot PRs use the existing **Codex GitHub connector** (`@codex review`)
+as the review gate.
+
+Default mode is `full`. Set repo variable `AI_AUTOMATION_MODE=triage_only` to
+classify issues without implement or the Codex fix loop.
+
+Third-party / fork PRs are **not** reviewed by this agent. Their initial Codex
+review is assumed to be auto-configured on the repo; this workflow only
+re-comments `@codex review` after the author pushes more commits
+(`pull_request` synchronize).

+|---|---|

+- External / fork PRs: only re-trigger Codex; no agent review and no commits.
+- Automation never publishes changes under `.github/` or automation scripts.

-# Cursor CLI automation
-
-GitHub Actions orchestration that uses **Cursor CLI** for issue triage and
-implementation of high-confidence bugs / small features. Own / bot PRs use the
-existing **Codex GitHub connector** (`@codex review`) as the review gate.
-
-**Current mode: `triage_only`.** Cursor still classifies new issues. Implement,
-issue follow-up coding, and the Codex review loop are paused. Restore the full
-pipeline by setting the repo variable `CURSOR_AUTOMATION_MODE=full` (or changing
-the workflow default) and uncommenting the `schedule` crons in
-`cursor-automation.yml`.
-
-Third-party / fork PRs are **not** reviewed by Cursor CLI. Their initial Codex
-review is assumed to be auto-configured on the repo; this workflow only
-re-comments `@codex review` after the author pushes more commits
-(`pull_request` synchronize).
-
-## Required secret
-
-| Secret | Purpose |
-|---|---|
-| `CURSOR_API_KEY` | Cursor CLI authentication (issue classify/implement + own PR fix loop) |
-
-Optional:
-
- `TRIAGE_GITHUB_TOKEN` — bot PAT (netcatty-bot) for opening PRs, labels, triage replies.
- `CODEX_REQUEST_GITHUB_TOKEN` — **maintainer PAT (binaricat)** used only for
-  `@codex review` comments so the Codex GitHub connector sees a human identity.
-  Falls back to `TRIAGE_GITHUB_TOKEN` / `GITHUB_TOKEN` if unset.
- `SLACK_WEBHOOK_URL` — status pings.
-
-Fork re-`@codex` uses `pull_request_target` (default-branch checkout only) so
-`GITHUB_TOKEN` can write comments. Write tokens are step-scoped only (never
-workflow-wide). Agent steps run without git credentials; publish uses a fresh
-clone.
-
-## Variables
-
-| Variable | Default | Purpose |
-|---|---|---|
-| `CURSOR_CODEX_FIX_MAX_ROUNDS` | `40` | Max Cursor fix ↔ `@codex review` loops on own/bot PRs |
-| `CURSOR_TRIAGE_DAILY_LIMIT` | `10` | Daily auto triage for non-collaborators |
-| `CURSOR_FOLLOWUP_DAILY_LIMIT` | `20` | Daily automatic follow-up runs per admitted issue before maintainer handoff |
-| `AUTOMATION_OWN_ACTORS` | `binaricat` | Logins treated as first-party PR authors |
-| `AUTOMATION_ISSUE_BOT_LOGINS` | `netcatty-bot,github-actions[bot]` | Bot logins ignored as issue follow-up authors and recognized in `@bot` mentions |
-
-## Manual retry
-
-Actions → **Cursor automation** → Run workflow → provide an issue or PR number.
-
-## Format recovery → triage
-
-`issue-format` and triage share the same title/body rules in
-`scripts/cursor-automation.cjs` (CJK-friendly `[Bug]`/`[Feature]` summaries).
-
-When a closed `invalid-format` issue is fixed, `issue-format` reopens it and
-**dispatches** `cursor-automation` via `workflow_dispatch` (GITHUB_TOKEN cannot
-silently chain `issues.reopened`, but `workflow_dispatch` is allowed).
-
-## Bot PR titles and bodies
-
-Implement agents write:
-
- `TITLE:` in `.cursor-runtime/implement-status.txt` → draft PR title
-  (`selectBotPrTitle`, with short `fix(#N): …` fallback)
- `.cursor-runtime/implement-pr-body.md` → full maintainer-style PR body
-  (`buildPullRequestBody` prefers this; short template only if missing/thin)
-
-Bodies always get bot markers + `Fixes #N` + an Automation footer when needed.
-
-## Codex label handoffs
-
-Terminal codex_loop outcomes always drop `automation:codex-loop`:
-
-| Outcome | Labels |
-|---|---|
-| clean / mark_ready | `automation:codex-clean` (+ bot-pr), no loop/human |
-| give_up / verify fail / empty fix | `ready-for-human`, no loop/clean |
-
-## Safety
-
- External / fork PRs: only re-trigger Codex; **no** Cursor CLI review and **no** commits.
- Own / bot PR Codex findings: Cursor CLI may push fixes (max rounds).
- Automation never publishes changes under `.github/` or automation scripts.
- Issue text is sanitized before prompts.
- Cursor credentials are exchanged before agent execution; agent tools receive
-  no API key or GitHub token and must run inside Cursor's command sandbox.
- Linux jobs install Cursor's versioned AppArmor profile after verifying its
-  pinned SHA-256. If the profile cannot be loaded or the sandbox preflight
-  fails, the job stops; it never falls back to an unsandboxed agent run.
- External facts are gathered in a separate read-only WebSearch pass running in
-  an empty temporary workspace. It has no repository, GitHub token, or raw
-  Cursor API key; shell network access remains blocked. Only its bounded,
-  source-linked notes are passed to classify, implement, or follow-up agents.
-  The workflow also verifies the CLI stream contains a real WebSearch/WebFetch
-  tool event; an answer that merely prints a URL is rejected.
- GitHub user-attachment images are fetched before that pass through a
-  digest-pinned imgproxy container. The proxy accepts only GitHub attachment
-  sources, blocks local/private destinations, bounds redirects, bytes, pixels,
-  and animation frames, and rasterizes successful results to temporary PNGs.
-  Cursor sees only those PNGs and a rewritten input without the source image
-  URL; any other URL still requires sourced external research. Proxy failures
-  stop the run and use the normal maintainer handoff.
- User-level WebSearch/WebFetch denials are written only after that research
-  pass (or in implement/fix jobs that never research). Pre-research sandbox
-  setup enables the command sandbox without denying web tools, so research is
-  not blocked by the later classify/follow-up denylist.
- WebSearch and WebFetch are explicitly denied again for classify, implement,
-  follow-up, and fix agents. Those stages cannot silently perform another web
-  request outside the isolated research pass.
- If needed WebSearch/WebFetch is unavailable or returns no source, automation
-  stops and hands the issue to a maintainer instead of inventing research.
- Author replies on `needs-info` / `triage:bug-needs-info` re-run classify with
-  the same dedupe, daily limit, and maintainer handoff rules.
-
-## Continuous issue follow-up
-
-Issue automation is not limited to the opening report. After an issue has been
-admitted, new comments from the issue author are reviewed as additions to the
-same work. The issue author can also explicitly mention `@netcatty-bot`; trusted
-repository members may do the same. Untrusted bystanders cannot trigger code
-changes by mentioning the bot, and an unadmitted issue cannot use a bot mention
-to bypass normal triage. A per-issue daily limit hands unusually busy threads to
-a maintainer instead of allowing unbounded agent runs.
-
-Follow-ups are coalesced and recorded by comment ID so queued runs do not reply
-or edit twice. When an automation PR is open, it is kept draft while Cursor
-compares the new information with the current diff:
-
- already covered: acknowledge the reporter and keep the existing PR unchanged;
- focused correction: update the same PR, run the full verification gate, then
-  restart Codex review on the new head;
- contradiction, larger scope, unsafe update, or no active PR needing work:
-  acknowledge the reporter and hand the issue/PR to a maintainer.
-
-Every clean-to-ready transition re-checks the source issue for automation bot
-PRs only (`automation:bot-pr` / bot PR marker). A maintainer PR that merely
-says `Fixes #N` is not kept draft solely because issue comments lack automation
-processed markers. Patch publication also verifies the PR head has not moved,
-so a follow-up update never overwrites a concurrent maintainer or automation
-push.
