Goals

• Ensure the PR is conflict-free with main.
• Keep CI green; fix failures when they occur.
• Squash-merge the PR once checks pass.
• Do not yield to the user until the PR is merged.
• No need to delete remote branches after merge.

Preconditions

• gh CLI is authenticated.
• You are on the PR branch with a clean working tree.

Steps

1. Find the PR for the current branch:

   sh
   1gh pr view --json number,url,headRefOid,mergeable,mergeStateStatus

2. Run local validation to confirm a clean baseline:

   sh
   1mix compile --warnings-as-errors && mix test

3. Handle uncommitted changes: stash or commit before proceeding.
4. Check mergeability. If mergeable == CONFLICTING:
   • Run the pull skill to rebase/merge origin/main.
   • Rerun validation after resolving.
   • Push the resolved branch.
5. Start the async watch helper:

   sh
   1python3 .codex/skills/land/land_watch.py

   Exit codes:
   • 2 — review comments exist (address them before merging)
   • 3 — CI failed (investigate and fix)
   • 4 — PR head was updated (pull and retry)
   • 5 — merge conflicts detected (run pull skill)
6. If exit code 2 (review comments): address each comment, commit fixes, push, re-run watch.
7. If exit code 3 (CI failed):
   • Read the failure output from gh run view.
   • Fix the issue; commit with fix: ... prefix.
   • Push and re-run watch.
8. If exit code 0 (checks green, no blocking reviews): squash-merge:

   sh
   1pr_title=$(gh pr view --json title -q .title)
   2pr_body=$(gh pr view --json body -q .body)
   3gh pr merge --squash --subject "$pr_title" --body "$pr_body"

9. Confirm merge succeeded: gh pr view --json state -q .state should be MERGED.

Review Handling

For each reviewer comment, choose one:

• Accept: implement the change, reply [codex] Done — <brief summary>
• Clarify: ask a targeted question if the comment is ambiguous
• Push back: acknowledge, provide rationale, offer alternative; prefix with [codex]

Always reply to a comment before pushing code changes that address it.

Notes

• Flaky tests: rerun once. If still failing, investigate root cause before pushing a skip.
• If CI failure is unrelated to your changes: note it in the workpad, push back to reviewer/maintainer, and do not proceed with merge until the issue is resolved or explicitly waived.
