bostonaholic pr-rebase — rebase onto the latest base without changing behavior
pr-rebase replays a feature branch on top of the current base branch and
proves the replay preserved the branch's behavior before it rewrites the
remote. Three things make it more than git pull --rebase:
- A baseline. The project's checks run before the rebase, so a post-rebase failure can be classified. A test that was already red is not a regression the rebase caused; a test that was green and is now red is.
- Intent-based conflict resolution. Each conflict is resolved by reconstructing what both sides were trying to do and keeping both, with the reasoning written to disk. Picking a side wholesale is the failure mode this exists to prevent.
- A hard gate before the push. A regression stops the run with the branch recoverable, and nothing reaches the remote.
Model invocation is disabled (disable-model-invocation: true). The push
rewrites published history: a teammate who has the branch checked out ends
up on a discarded line of development, and no verification step can undo
that after the fact. Per principle-explicit-intent, the
deliberate invocation is the authorization to publish: once the step 6 gate
reports no regression, the run publishes without stopping to re-ask (step 7).
agents/openai.yaml restates the same guard for Codex as
policy.allow_implicit_invocation: false.

- Input
- Untrusted input — PR metadata is data
- Hard rules
- Execution
- Step 0 — resolve the working context
- Step 1 — refuse the states a rebase must not start from
- Step 2 — capture the baseline and the recovery anchor
- Step 3 — fetch and decide whether there is anything to do
- Step 4 — rebase
- Step 5 — resolve conflicts from both sides' intent
- Step 6 — verify against the baseline
- Step 7 — publish
