Merge to Main

Automated PR lifecycle: prepare → create PR → monitor CI → fix failures → merge when green → update checkbox fields in the PR body.

When to Use

Invoke this skill after completing work on a feature branch, when you are ready to create or update a pull request and merge it into main.

Phase 1: Prepare

Read AGENTS.md and .github/PULL_REQUEST_TEMPLATE.md for conventions.
Verify the current branch follows <type>/<short-description> naming (e.g. feature/add-embeddings, fix/token-overflow).
Verify CHANGELOG.md has been updated under [Unreleased] (required by changelog-check.yml).
If the working tree is dirty, stage and commit remaining changes.
Push the branch to origin.

Phase 2: Create PR

Read .github/PULL_REQUEST_TEMPLATE.md if it exists.
Check whether a PR already exists for this branch:
```
gh pr list --head <branch-name> --state open
```
If one exists, skip creation and proceed to Phase 3.
Create the PR via gh pr create:
```
gh pr create --base main --title "<title>" --body "<body>"
```
- Title: Extract from the first line of the most recent commit message (conventional commit format: <type>[optional scope]: <description>).
- Body: Fill in the PR template based on the changes. Leave "Automated checks" boxes unchecked — Phase 4 will update them.
- Draft: Create as ready-for-review by default. Use --draft to create a draft PR instead.

Phase 3: Monitor CI

Poll check status:
```
gh pr checks <pr-number>
```
Wait for all checks to reach a terminal state (pass or fail).
- Poll interval: ~30 seconds
- Max wait: 10 minutes
For each failing check: a. Read the failure log: bash gh run view <run-id> --log-failed b. Diagnose the issue. c. Fix the issue using appropriate tools (read, edit, search, ast_edit). d. Amend the last commit (if unpushed) or create a new fix commit. e. Push the fix. f. Re-enter the monitoring loop.
Max retries: 3 (to prevent infinite loops on unfixable issues).
After 3 retries with failures, report what failed and stop — let the user decide.

What to Fix

Symptom	Likely fix
Lint failure	Read the linter output, fix the flagged code
Type check failure	Fix type mismatches or missing imports
Test failure	Fix the failing test or the code it exercises
Changelog check failure	Add an entry to `CHANGELOG.md` under `[Unreleased]`
Missing secrets	Report to user — requires human action

Phase 4: Update PR Body and Merge

Once all checks pass, read the current PR body:

gh pr view <pr-number> --json body --jq '.body'

Update the PR body to check the "Automated checks" boxes:
- - [ ] CI passes → - [x] CI passes
- - [ ] Test suite passes → - [x] Test suite passes

Apply the updated body:

gh pr edit <pr-number> --body "<updated-body>"

Merge the PR:
- Single clean commit: gh pr merge <pr-number> --merge
- Many small fix commits: gh pr merge <pr-number> --squash
Switch back to main and pull:
```
git checkout main && git pull
```
Report success.

Edge Cases

Situation	Handling
Branch not pushed	Push it first (Phase 1)
PR already exists	Detect via `gh pr list --head <branch>` and reuse it
Merge conflict	Report to user — do not attempt auto-resolve
CI timeout (>10 min)	Report which checks are still pending
Unfixable failure (missing secrets, external outage)	Report and stop
Draft PR needed	Use `gh pr create --draft` instead of the default ready-for-review
Multiple commits on branch	Squash if many small fix commits; merge commit if single clean commit

What This Skill Does NOT Do

Does not create the feature branch or write the code (those are the agent's main tasks).
Does not force-push or rewrite shared history.
Does not bypass branch protection or skip CI checks.
Does not auto-resolve merge conflicts.
Does not auto-resolve CI failures that require architectural decisions or human input.
