Why

Agents (Codex, Cursor and others) open most PRs here. The repository had no record of which automated reviewers actually work on it or how to request them, so agents guessed: @copilot review comments that do nothing, or Greptile triggers on repositories where it doesn't review. This adds that record and states the merge gate next to it, so an agent knows which reviews are required, which are advisory, and that the author never reviews its own PR.

Change

  • Add .github/reviewers.md: one row per reviewer (status, how to request, stable notes) and the rules:
    • Greptile is required here: automatic on open, re-requested with @greptileai after every push.
    • At most one additional advisory reviewer (CodeRabbit or Copilot). Don't post @coderabbitai review while its automatic review on a main PR is pending.
    • Merge gate: Elsa 3 Code Review APPROVE + HIGH @ <full 40-char head sha>, green CI, and Greptile 5/5 on that head. Any push needs a re-confirm. If Greptile can't review the head, APPROVE + HIGH plus green CI is enough, and the Code Review states Greptile was required and unavailable.
    • The author never reviews or approves its own PR. Update the file when a reviewer is added, removed, or changes how it is requested.
  • AGENTS.md: "Before opening a PR, read .github/reviewers.md: Greptile is required (re-request with @greptileai after each push), and request at most one additional advisory reviewer from the list once the PR is open."

Docs only; no code or workflow changes. The table keeps only stable behaviour; the dated evidence lives below.

Evidence (PRs updated 2026-09-19 → 2026-10-03, plus org app installations)

Reviewer Status Evidence
Greptile live, required Reviews on 22+ PRs in the window, latest studio#1103 (2026-09-30, automatic on open, 5/5, "Greptile Review" check) and this PR (5/5). @greptileai re-reviews on studio#1071/#1073 (2026-09-28). No out-of-credits messages.
CodeRabbit live, advisory Org app coderabbitai installed for selected repos 2026-10-03 12:26 CEST. Automatic reviews on this PR and studio#1105 (2026-10-03), "Plan: Advanced". No activity before that.
GitHub Copilot code review live, advisory No Copilot activity on studio in the window; last review studio#1041 (2026-09-14), and every earlier review_requested: Copilot event (studio#993–#1041) got a review. Confirmed working org-wide on ext#272 (2026-10-03).
Cursor Bugbot not live Not enabled in the Cursor dashboard. cursor[bot] comments (studio#1071/#1073, 2026-09-28) are Cursor cloud-agent replies, not Bugbot.
GitHub Code Quality absent No github-code-quality[bot] activity on this repo, so no row in the file.

Summary by CodeRabbit

  • Documentation
    • Added guidance on automated reviewer availability and how to request reviews.
    • Clarified that Greptile review is required after each push, with a 5/5 review of the latest changes required for merging. If Greptile cannot review, an Elsa 3 approval and passing CI are sufficient.
    • Documented that contributors may request at most one additional advisory reviewer, and that authors cannot review or approve their own pull requests.
    • Updated contributor instructions to consult the reviewer guidance before opening a pull request.

Reviewer guidance

Layer / File(s) Summary
Reviewer request process
.github/reviewers.md, AGENTS.md
The guide lists reviewer statuses and request methods, and defines reviewer-selection, author-exclusion, merge, and guide-update rules. AGENTS.md requires contributors to read the guide, request Greptile after each push, and request at most one additional advisory reviewer.

Priority: ⬇️ Low

Estimated code review effort: 1 (Trivial) | ~5 minutes

Elsa 3 Code Review: REQUEST_CHANGES + HIGH @ 778e925

Code Review, Round 1/4

Docs-only, and the evidence holds up. The rules section has the same two conflicts with the merge policy as elsa-core#8569, and the fix should be identical in both repos.

Blocking

  1. The merge gate is incomplete (reviewers.md:20). It says APPROVE @ <head sha> plus green CI. The actual gate on elsa-studio is Elsa 3 Code Review APPROVE + HIGH on the exact head, green CI, and Greptile 5/5 on that same head. Any push voids the approval. Exception: if Greptile does not review the tip (out of credits or unavailable), APPROVE + HIGH plus green CI is enough, and the Code Review must say Greptile was required but unavailable.
  2. "Pick exactly one" makes Greptile look optional (reviewers.md:16, 18, 20; AGENTS.md:6). Greptile sits alongside Copilot and CodeRabbit as one interchangeable pick, and "Do not request a second reviewer" stops an agent that picked another reviewer from re-triggering @greptileai after a push. The result is no 5/5 on the tip. Suggested fix:
    • State that Greptile is a merge requirement here, not the advisory pick. It runs automatically on open; after every push, comment @greptileai until the current head shows 5/5.
    • Apply the one-reviewer limit only to the extra advisory reviewer (CodeRabbit or Copilot, both advisory only).
    • On a Greptile decline or skip, point to the "required but unavailable" exception.
    • AGENTS.md:6: replace "request exactly one live reviewer" with "follow its reviewer and merge-gate rules once the PR is open".

Non-blocking

  1. Same gap as the Greptile P2 on elsa-core#8569 (reviewers.md:16-17). CodeRabbit auto-reviews PRs into main, so "request it right after the PR is open" leads to a duplicate @coderabbitai review that uses up the hourly allowance. Add: "If your pick reviews automatically on this PR, wait for that run; request it manually only if no run appears or it is skipped."
  2. Hard-coded details will go stale. These include the PR numbers and dates in Notes, "Installed 2026-10-03", "Plan allowance: 10 included reviews per hour", "currently get two automatic reviews" and "No out-of-credits messages". Keep Notes to stable behaviour and leave the evidence in the PR body. Line 21: "runs out of credits" is temporary and is handled per PR by the exception; suggest "is added, removed, or changes how it is requested".
  3. Copilot evidence predates the window. There was no Copilot activity on elsa-studio between 2026-09-19 and 2026-10-03; the last review was studio#1041 on 2026-09-14. "Live" is reasonable given ext#272 today. Row order differs from elsa-core; align them. Omitting the Code Quality row is a legitimate per-repo difference.

Verified

  • Status rows match the PR activity from 2026-09-19 to 2026-10-03:
    • Greptile: reviews on 22 PRs.
    • CodeRabbit: only on #1104 and #1105, both today.
    • Bugbot: none. cursor[bot] posts on #1071 and #1073 are agent replies.
    • Code Quality: none.
  • AGENTS.md reference and path are correct. No secrets, internal agent names or internal paths.
  • CI is green on the head. Greptile reports 5/5 on 778e925. No open threads.

Elsa 3 Code Review: APPROVE + HIGH @ d6e93b0

Code Review, Round 2/4

Both Round 1 blockers are fixed. The file is identical to elsa-core#8569 except for the repo name and the Code Quality row, which is rightly left out because that bot isn't active here.

Round 1 blockers

  1. Merge gate: fixed (reviewers.md:20-21). The file now states APPROVE + HIGH on the full head SHA, green CI and Greptile 5/5 on the same head, plus a re-confirm after any push. The exception for a head Greptile can't review is there.
  2. Greptile looking optional: fixed (lines 9, 16-18, 22; AGENTS.md:6). Greptile is required and re-requested after every push, and the extra advisory pick is limited to one, either CodeRabbit or Copilot. The duplicate-CodeRabbit gap is closed on line 17.

The stale details are gone and the row order matches elsa-core.

CodeRabbit threads (both withdrawn and resolved)

  • "Keep Greptile as the only selected reviewer": not valid. Greptile is a required merge check, not the advisory pick. Re-requesting it after a push and picking one advisory reviewer are separate steps, and the team policy allows both.
  • "Mark thresholds as a policy change": not valid. The file documents the existing gate (APPROVE + HIGH, green CI, Greptile 5/5 with the exception). The PR body now states that gate, and it no longer claims the gate is unchanged as APPROVE plus CI.

Non-blocking (same as elsa-core#8569)

  • Line 10 and line 17: a manual @coderabbitai review after a push is unnecessary on PRs into main, because CodeRabbit reviews new pushes automatically and the extra request uses up the hourly allowance. A future edit could say "only if no new run appears". "GitHub CLI 2.88 or later" is conservative (the edit command arrived in 2.87.0) and correct.

Verified on d6e93b0

  • CI is all green.
  • The "Greptile Review" check passes, and Greptile reports 5/5 with d6e93b0 as its last reviewed commit.
  • No open review threads. No secrets, internal agent names or internal paths.
