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 most PRs in the window (99 of the 100 most recently updated; about 167 overall), latest core#8568 and core#8567 (2026-10-03) and this PR (5/5, "Greptile Review" check). Automatic on open; @greptileai re-reviews after pushes. Non-allow-listed authors get "PR author is not in the allowed authors list" (core#8557, dependabot, 2026-09-30).
CodeRabbit live, advisory Org app coderabbitai installed for selected repos 2026-10-03 12:26 CEST. Reviews on core#8568, #8138, #8567 and this PR (2026-10-03), "Plan: Advanced", "up to 10 included reviews per hour". On core#8566 (base release/3.9.0): "Review skipped: Auto reviews are disabled on base/target branches other than the default branch".
GitHub Copilot code review live, advisory Last review on core#8045 (2026-09-14); confirmed working org-wide on ext#272 (2026-10-03). A @copilot review comment on core#8266 (2026-09-23) produced no review. core#7907 (bot-authored, 2026-08-03): "Copilot was unable to review this pull request because there is no eligible user to bill". No quota messages.
Cursor Bugbot not live Not enabled in the Cursor dashboard. cursor[bot] activity (core#8491/#8492, 2026-09-26) is Cursor cloud-agent thread replies, not Bugbot reviews.
GitHub Code Quality informational github-code-quality[bot] reviews or comments on 41 of the 247 PRs updated in the window (recounted across all of them), latest core#8567 and #8572 (2026-10-03). Automatic, not requestable.

Summary by CodeRabbit

  • Documentation
    • Added review guidance requiring Greptile requests to be renewed after each push and allowing at most one additional advisory reviewer once a pull request is open.
    • Documented reviewer roles and merge requirements: Elsa 3 approval for the current revision, passing CI, and a Greptile 5/5 score, with an exception when Greptile cannot review.

Elsa 3 Code Review: REQUEST_CHANGES + HIGH @ 426541f

Code Review, Round 1/4

Docs-only, and the evidence holds up. Two rules in .github/reviewers.md contradict the merge policy, though, and the file is meant to be the reference agents follow.

Blocking

  1. The merge gate is incomplete (reviewers.md:21). It says APPROVE @ <head sha> plus green CI. The actual gate on elsa-core 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:17, 19, 21; AGENTS.md:20). Greptile is listed as one of three interchangeable picks, and line 17 says "Do not request a second reviewer". An agent that picks Copilot or CodeRabbit is therefore told not to re-trigger Greptile with @greptileai after a push, so the tip never gets 5/5. Line 21 also calls "this review" advisory without carving Greptile out. Suggested fix:
    • Add a rule saying 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.
    • Make the one-reviewer limit apply only to the extra advisory reviewer (CodeRabbit or Copilot, both advisory only).
    • Line 19: if Greptile declines or skips, point to the "required but unavailable" exception rather than just "request a different live reviewer".
    • AGENTS.md:20: replace "request exactly one live reviewer" with "follow its reviewer and merge-gate rules once the PR is open".

Non-blocking

  1. Greptile P2 (reviewers.md:18): fair, low severity. CodeRabbit auto-reviews PRs into main a few minutes after open, so "request it right after the PR is open" leads to a duplicate @coderabbitai review that uses up the hourly allowance (this PR's own run reported 6 of 10 left). Leaving it alone is acceptable as a P2. Since blockers 1 and 2 need a push anyway, fold in one line: "If your pick reviews automatically on this PR, wait for that run; request it manually only if no run appears or it is skipped." Then reply on and resolve the thread.
  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 "Last review core#8045 (2026-09-14)". Keep Notes to stable behaviour and leave the evidence in the PR body; Last verified is enough. Line 22: credit exhaustion is temporary and is handled per PR by the exception, so "runs out of credits" will cause churn. Suggest "is added, removed, or changes how it is requested".
  3. Consistency. Row order differs from elsa-studio (Greptile, CodeRabbit, Copilot here; Greptile, Copilot, CodeRabbit there). Align them.

Verified

  • Status rows match the PR activity from 2026-09-19 to 2026-10-03:
    • Greptile: reviews on about 167 PRs.
    • CodeRabbit: active since today on PRs into main; "Review skipped" on release/3.9.0.
    • Copilot: last reviews 2026-09-13/14. Nothing newer on core, but the service is confirmed working org-wide by ext#272 today.
    • Bugbot: none. cursor[bot] posts are agent replies only.
    • Code Quality: on 41 PRs (the PR body says 8; the file itself is fine).
  • AGENTS.md reference and path are correct. src/studio/AGENTS.md defers review rules to the root file. No secrets, internal agent names or internal paths.
  • CI is green on the head. Greptile reports 5/5 on 426541f. One open thread: the Greptile P2 above.

Elsa 3 Code Review: APPROVE + HIGH @ ad040a7

Code Review, Round 2/4

Both Round 1 blockers are fixed, and no new wording contradicts the merge policy.

Round 1 blockers

  1. Merge gate: fixed (reviewers.md:21-22). The file now states APPROVE + HIGH @ <head sha> on the full head SHA, green CI and Greptile 5/5 on the same head, and any push needs a re-confirm. The exception for a Greptile-less head is there, including the requirement to say Greptile was required and unavailable.
  2. Greptile looking optional: fixed (lines 9, 17-19, 23; AGENTS.md:20). Greptile is marked required and is re-requested after every push. The one-reviewer limit now covers only CodeRabbit or Copilot, and both are marked advisory. Round 1's duplicate-CodeRabbit P2 is addressed on line 18.

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

Non-blocking

  • Line 10 and line 18: "comment @coderabbitai review … for a re-review after a push" is unnecessary on PRs into main. CodeRabbit re-reviewed this PR's pushes on its own (426541f, ad040a7, with no request), so a manual re-request uses up the hourly allowance. Greptile also re-reviewed 426541f without being asked. A future edit could say "re-request only if no new run appears on the new head". This doesn't conflict with the policy.
  • CLI version (line 11): gh pr edit --add-reviewer @copilot first shipped in GitHub CLI 2.87.0; 2.88.0 added gh pr create --reviewer @copilot. "2.88 or later" is conservative and correct. No change needed.
  • Title: "Advisory PR reviewers" undersells a file that now also defines the merge gate. Something like "PR reviewers and merge gate" would fit better.

Verified on ad040a7

  • CI is all green.
  • The "Greptile Review" check passes, and Greptile reports 5/5 with ad040a7 as its last reviewed commit.
  • No open review threads. The CodeRabbit CLI-version nit was withdrawn and resolved, and the Round 1 P2 is resolved.
  • The PR body now matches the file. No secrets, internal agent names or internal paths.
