description

Rebase one stale PR branch onto main with intelligent conflict resolution — replay the branch onto a freshly-fetched origin/main, resolve each conflict by understanding both sides, re-validate against this repo's project-mechanics, and leave the branch rebased and clean for the host to force-push. Use when invoked from the stoker rebase-phase prompt, or when the user asks to rebase a PR branch onto main and resolve conflicts — and you are working in a stoker-installed repo. Consumes project-mechanics (Phase 0.5 prelude) and MAY delegate to stoker-work.

stoker-rebase — rebase one PR branch onto main

You are the rebase primitive of the stoker AFK loop. A selection phase picked an open PR whose branch is behind main, and the host checked out the branch and tried an automated git rebase origin/main that conflicted. That attempt was aborted, so the branch is back at its own tip — clean and checked out, not mid-rebase. Your job is to redo the rebase, this time resolving the conflicts intelligently, then re-validate.

You may read the branch's diff and source freely; you never read issue or PR comments — that is stoker's trust boundary.

Phase 0: Branch safety

The host has already checked out the PR's head branch — confirm with git branch --show-current and verify it is not main. If you are somehow on main, stop and report the problem rather than rebasing.

Phase 0.5: Read project mechanics

Before continuing, read .claude/skills/project-mechanics/SKILL.md. It defines this repo's focused_test / complete_test / lint_touched / lint_all / typing commands and any monorepo selectors. If the file is missing, stop and ask the user how to run tests/lint in this repo before proceeding — do not guess.

The phases below reference these command names verbatim. When you see <lint_all>, substitute the value from the ## Lint section, and so on.

Phase 1: Start the rebase

Freshen the base and replay the branch onto it:

git fetch --force origin main
git rebase origin/main

If the rebase completes with no conflict, skip to Phase 3 (re-validate). Otherwise git stops at the first conflicting commit — git status lists the unmerged paths.

Phase 2: Resolve conflicts intelligently

For each conflicting file, open it and understand both sides:

• The base side is main's current content; the branch side is the commit being replayed. Read the surrounding code and the commit's intent (git log, git show <commit>) so you keep both changes' meaning — never resolve by blindly discarding one side.
• If a resolution is mechanical (an import list, adjacent edits to different functions), apply it in place.
• If a resolution warrants real reasoning — overlapping logic, a renamed symbol both sides touch, a behavior change — treat the merged result as new code and lean on the stoker-work skill's red/green discipline so the resolution lands with a test.

Once a file is resolved, git add <file>. When every conflict in the current step is staged, continue:

git rebase --continue

Repeat Phase 2 for each conflicting step until the rebase finishes.

If you cannot resolve the conflicts — the two sides are genuinely incompatible, or resolution would change behavior you can't verify — abort so the working tree is left clean:

git rebase --abort

Then report what blocked you and stop (the host marks the PR agent-stuck). Do not force a resolution you don't understand.

Phase 3: Re-validate

After the rebase completes, reach a clean validation fixpoint against project-mechanics — a clean textual rebase can still break the build when main moved underneath the branch:

1. git add -N any new untracked files so the full-tree tools see them.
2. Run <lint_all>, then <typing>, then <complete_test>. Fix any failure before continuing (a fix is a normal commit on top of the rebased branch).
3. If anything auto-fixed code, fixpoint-loop on <lint_touched> over the touched files until it exits clean.
4. git reset HEAD the intent-to-add files so the tree is back to a clean, fully-committed state.

If validation cannot be made green, abort the rebase (git rebase --abort) and report the blocker rather than leaving broken state.

Phase 4: Hand back to the host — do not push

Leave the branch rebased, committed, and clean. Do not run git push and do not force-push: the host verifies the branch is now up to date with main and force-pushes it with lease. Pushing here would race that step.

End your response with a single <stoker-status>done</stoker-status> marker once the rebase is complete and validation is green (or once you have aborted and reported a blocker), so the host knows the phase ran. Do not emit any <stoker-pick> or stoker-review markers — those belong to other phases.
