feat(auto-rebase): trigger Claude agentic rebase on merge conflict#280don-petry wants to merge 7 commits into
Conversation
When auto-rebase-reusable.yml encounters a conflict it cannot resolve via the merge strategy, it already posts a sentinel comment (<!-- auto-rebase-conflict -->). This commit wires that sentinel to a new claude-rebase job that fires when github-actions[bot] posts that comment on a PR, giving Claude a chance to rebase the branch and resolve conflicts before escalating to a human. Changes: - auto-rebase-reusable.yml: update conflict comment to mention Claude will attempt an automatic rebase; switch manual instructions from merge to rebase (git rebase --continue / --force-with-lease) - claude-code-reusable.yml: add claude-rebase job triggered by the <!-- auto-rebase-conflict --> sentinel; Claude checks out the branch, rebases onto the base branch, resolves conflicts using best-effort judgment (prefer main's side for superseded pins, keep PR's side for novel changes), pushes, and posts a summary; aborts cleanly if application-code conflicts require human judgment Closes #279 Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>

Pull request overview
This PR adds an agentic fallback for auto-rebase conflicts: when the merge-based branch update hits a conflict, the workflow posts a sentinel comment intended to trigger Claude to attempt a rebase and conflict resolution.
Changes:
- Updates the auto-rebase conflict comment to mention Claude’s automatic rebase attempt and rebase-based manual fallback.
- Adds a
claude-rebasejob to the reusable Claude workflow for sentinel-triggered conflict resolution. - Provides Claude with instructions for checkout, rebase, conflict handling, force-with-lease push, and summary posting.

…ncy, git identity, tests Addresses all issues raised by Codex and Copilot on PR #280: P1 — GITHUB_TOKEN events don't trigger issue_comment workflows: Switch from comment-based trigger to repository_dispatch (one of only two event types GITHUB_TOKEN IS permitted to trigger workflow runs for). auto-rebase-reusable.yml fires `gh api .../dispatches` with event_type claude-rebase; claude.yml adds `repository_dispatch: types: [claude-rebase]`; claude-code-reusable.yml claude-rebase job triggers on repository_dispatch. P2 — Idempotency sentinel too broad (one-shot per PR): Replace `<!-- auto-rebase-conflict -->` with a SHA-keyed sentinel `<!-- auto-rebase-conflict:{base_sha} -->` where base_sha is the first 8 chars of the base branch HEAD.

Review mode: triage-approved (single reviewer)
Summary
Adds an agentic auto-rebase fallback: when the merge strategy hits a conflict, auto-rebase-reusable.yml fires a repository_dispatch event (event_type: claude-rebase) which triggers a new claude-rebase job in claude-code-reusable.yml. Claude checks out the branch, rebases onto the base branch, resolves conflicts with bounded judgment, and pushes with --force-with-lease.
The second commit (75afe83) addressed all prior AI-reviewer feedback (Codex P1/P2, Copilot) — see below. Triage's low-risk classification is correct; the implementation has appropriate safeguards.
Linked issue analysis
Closes #279 (feat(auto-rebase): assign conflicting PRs to Claude for agentic rebase). All acceptance criteria are addressed:
- ✅ Conflict comment now notes Claude will attempt the rebase
- ✅ New
claude-rebasejob dispatched viarepository_dispatch(the GITHUB_TOKEN-triggerable path) - ✅ Clear abort + summary comment path for unresolvable conflicts
- ✅ Idempotency preserved via SHA-keyed sentinel (
<!-- auto-rebase-conflict:{base_sha} -->)
Findings
Prior review feedback resolved (commit 75afe83):
- Codex P1 —
issue_commentevents fromGITHUB_TOKENdon't trigger workflows. Fixed by switching torepository_dispatch, which is one of only two event typesGITHUB_TOKENis permitted to trigger. - Codex P2 — Sentinel was one-shot per PR lifetime. Fixed by SHA-keying the sentinel to the base-branch HEAD; each new base merge resets the gate.
- Codex P2 — Missing git identity before
rebase --continue. Addedgit config user.name/user.emailto the Claude prompt. - Copilot —
git rebase --continueper-file instead of per-commit. Clarified in the prompt: stage all files for the commit, then--continueonce. - Test gap — Extracted conflict-handling logic to
scripts/auto-rebase.sh; added 12-test BATS suite + ShellCheck gate (.github/workflows/auto-rebase-tests.yml).
Security posture (the reason this stays MEDIUM, not HIGH):
- All third-party actions are pinned to commit SHA (
actions/checkout@de0fac2e…,anthropics/claude-code-action@476e359e…). claude-rebasejob uses a restricted--allowedToolsallowlist (Bash(git*:*),Bash(gh pr ...),Bash(gh api:*),Edit,Write) rather than unrestricted tool use.- Permissions on the new job are scoped (
contents: write,pull-requests: write,id-token: write,issues: write, plus read-onlyactions/checks). - Concurrency group
claude-rebase-${pr_number}withcancel-in-progress: trueprevents stacking. - 30-minute timeout caps blast radius.
- Push uses
--force-with-lease, not raw--force. - Rebase strategy explicitly aborts on complex application-code conflicts and falls back to a human-readable comment.
repository_dispatchpayload is constructed from internal PR metadata (PR number, head ref, base branch), not from untrusted user input.
Minor observations (non-blocking):
- The
--allowedToolspatternBash(git*:*)is broad — it matches any subcommand ofgitwith any arguments. Given the scoped checkout and--force-with-leasepush, the realistic blast radius is bounded to the PR branch, but tightening to specific git subcommands (git rebase:*,git push:*,git checkout:*,git add:*,git config:*,git fetch:*) would be a defense-in-depth win for a future PR. secrets.GH_PAT_WORKFLOWS || github.tokenfallback for checkout/push: when the PAT is absent, force-pushing to a PR branch that touches.github/workflows/will fail with the sameworkflowspermission error the original workflow already handles upstream. That's the right failure mode (loud, not silent), and the manual-rebase comment path is preserved.

P1 — script not found when reusable is called from other repos: The checkout in auto-rebase-reusable.yml checked out the CALLER's repository, so scripts/auto-rebase.sh was only present when the .github repo called itself. Fix: always checkout petry-projects/.github (the canonical home of the scripts) regardless of which repo invokes the reusable. P2 — sentinel posted before dispatch, blocking retries on dispatch failure: Reorder handle_conflict to fire repository_dispatch first, post the SHA-keyed sentinel comment only after dispatch succeeds. If dispatch fails the comment is never written, so the next auto-rebase run for the same base SHA can retry cleanly. Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>

For downstream repos that pick up the updated auto-rebase-reusable.yml@v1 but have not yet copied the updated local claude.yml stub with on.repository_dispatch, this API call can succeed while no Claude workflow is actually listening on the repo’s default branch; GitHub documents repository_dispatch runs only when the workflow file exists on the default branch. Because the sentinel comment is posted immediately after this and future runs skip the same base SHA, those conflicted PRs are left with “Claude has been dispatched” but no rebase attempt. Add a compatibility check/fallback or avoid writing the sentinel until a run is confirmed.

When a downstream repo invokes auto-rebase-reusable.yml@v1, this checkout does not specify ref, so the helper script is loaded from petry-projects/.github’s default branch rather than the same version as the reusable. I checked actions/checkout’s README: for a different repository, omitted ref “uses the default branch.” That bypasses the standards guarantee that @v1 insulates adopters from changes on main, so any future incompatible edit to scripts/auto-rebase.sh can break all pinned callers immediately; checkout the same tag/SHA as the reusable or vendor the script within the versioned workflow.

Review mode: triage-approved (single reviewer, confirmation pass)
Summary
Confirmation review on a triage-approved PR. The prior bot review approved de97a13; two commits since address feedback from a second Codex review and a merge brings in orthogonal compliance changes from PR #277. The fixes are surgical, the security posture is unchanged (and arguably tightened), and CodeRabbit explicitly approved this exact SHA. Approving.
Linked issue analysis
Closes #279 (feat(auto-rebase): assign conflicting PRs to Claude for agentic rebase). All acceptance criteria remain addressed; the new commits don't alter the user-visible contract — they just fix two correctness/operability bugs uncovered by Codex on the prior SHA.
Findings — what changed since the prior approval (de97a13)
1. auto-rebase-reusable.yml — checkout the canonical scripts repo (commit a8b49e9)
The checkout step previously used the default (caller's) repository, so scripts/auto-rebase.sh was only present when .github called itself. Fixed by setting repository: petry-projects/.github on actions/checkout. This is correct: the script's interactions with the caller's PR go through gh CLI against $REPO (= github.repository, the caller), so the caller's working tree isn't needed in this job.
2. scripts/auto-rebase.sh — dispatch before sentinel (commit a8b49e9)
handle_conflict() now fires repository_dispatch first and posts the SHA-keyed sentinel comment only after dispatch succeeds. Previously, a failed dispatch would still leave the sentinel in place, permanently blocking retries for the current base SHA. The new order trades that failure mode for the much rarer case of a successful dispatch followed by a failed comment post — which would result in (at most) one duplicate Claude run on the next auto-rebase, bounded by the existing claude-rebase-${pr_number} concurrency group with cancel-in-progress: true. Net win.
3. Merge from main (commit 55877e1)
Merges PR #277 (gitleaks secret-scan job using SHA-pinned binary install with checksum verification, dtolnay SHA pin, root .gitleaks.toml). Orthogonal to this PR's scope; no interaction with the auto-rebase logic.
Security posture (still MEDIUM, not HIGH):
- All third-party actions SHA-pinned (unchanged).
claude-rebasejob retains its restricted--allowedToolsallowlist (unchanged).- Scoped job permissions,
--force-with-leasepush, 30-min timeout, SHA-keyed sentinel idempotency, explicit abort-on-complex-conflict path — all unchanged. - The new explicit
repository: petry-projects/.githubcheckout pins the script source to a trusted location, which is a small defense-in-depth improvement over relying on caller-controlled checkout content.
Carry-forward observation (non-blocking, same as prior review):
The Bash(git*:*) allowlist pattern is still broad. Tightening to specific git subcommands would be a future-PR defense-in-depth win, but the blast radius is bounded by the scoped checkout and force-with-lease, so this stays non-blocking.

If the repository_dispatch request fails for one conflicted PR due to a transient API/token problem, this unguarded gh api runs under the sourced script's set -e, so the entire auto-rebase step exits instead of moving on to the remaining PRs. That regresses the workflow's per-PR graceful handling: a single dispatch failure can leave later behind branches unprocessed until another push or manual run.

This privileged job now trusts any repository_dispatch payload with action claude-rebase, but it never re-checks that the referenced PR is the same-repo, non-Dependabot PR that auto-rebase is supposed to handle. If another automation or a maintainer token dispatches this event with a fork PR number, the job still gets write permissions and inherited secrets and then instructs Claude to gh pr checkout and rebase that PR; add the same head-repo/bot gate used by the auto-rebase producer before invoking Claude.

Align gh-call log format with the documented contract.
The comment says argv is tab-separated, but the stub writes space-separated args. This can blur argument boundaries and weaken assertions for arguments containing spaces.

In `@test/workflows/auto-rebase/helpers/setup.bash` at line 84, The
ar_gh_call_count helper uses grep -c "$pattern" which treats pattern as a regex;
change it to fixed-string matching so special chars in $pattern don't get
interpreted. Update the invocation that sets count (the line using count=$(grep
-c "$pattern" "${AR_GH_LOG:-/dev/null}" 2>/dev/null) || count=0) to use grep
--fixed-strings (or -F) and -- to end options, keeping the same redirection and
fallback so it still assigns count and handles missing AR_GH_LOG correctly.

Closing — the core feature (agentic Claude rebase fallback) was delivered via #281, which merged a more complete implementation (PAT-based sentinel, SHA-keyed delete-and-repost idempotency, semver version comparison in the prompt). PR #280's unique contribution was the test suite ( Follow-up: open a new PR that extracts #281's inline conflict-handling logic into |

Summary
auto-rebase-reusable.yml: when the merge strategy fails with a conflict, the existing sentinel comment (<!-- auto-rebase-conflict -->) now tells the author that Claude will attempt an automatic rebase. Manual fallback instructions are updated fromgit mergetogit rebase --continue / --force-with-lease.claude-code-reusable.yml: newclaude-rebasejob triggered byissue_commentevents wheregithub-actions[bot]posts a comment containing<!-- auto-rebase-conflict -->on a PR. Claude checks out the branch, rebases onto the base branch, resolves conflicts with best-effort judgment, pushes, and posts a result summary. Aborts cleanly if conflicts require human judgment.How the trigger works
The sentinel is idempotent — auto-rebase won't re-post it on subsequent runs, so Claude only gets one automatic attempt per conflict. If Claude's rebase also fails it posts a clear summary and a human takes over.
