+# Land PR (OpenClaw)
+
+Use this skill to land **openclaw/openclaw** PRs only.
+
+## Safety + Scope
+
+- **Repo restriction:** only `openclaw/openclaw`. If the PR is in any other repo, stop and ask.
+- **Confirmation required:** before rebase/force-push/merge, summarize the plan and ask for explicit approval.
+- **Never close PRs.** PR must end in GitHub state **MERGED**.
+- **No GitHub comments** unless the user explicitly approves (global policy).
+
+## Instructions
+
+Follow the checklist here:
+- `/var/lib/clawd/repos/clawdinators/scripts/landpr.md`
+
+If the user did not specify a PR, use the most recent PR mentioned in the conversation. If ambiguous, ask.
+
+When ready to execute the merge step, confirm which strategy to use (rebase vs squash). If unclear, ask.
+
+After completion, verify PR state == MERGED.

+Input
+- PR: <number|url>
+  - If missing: use the most recent PR mentioned in the conversation.
+  - If ambiguous: ask.
+
+Do (end-to-end)
+Goal: PR must end in GitHub state = MERGED (never CLOSED). Use `gh pr merge` with `--rebase` or `--squash`.
+
+1) Repo clean: `git status`.
+2) Identify PR meta (author + head branch):
+
+   ```sh
+   gh pr view <PR> --json number,title,author,headRefName,baseRefName,headRepository --jq '{number,title,author:.author.login,head:.headRefName,base:.baseRefName,headRepo:.headRepository.nameWithOwner}'
+   contrib=$(gh pr view <PR> --json author --jq .author.login)
+   head=$(gh pr view <PR> --json headRefName --jq .headRefName)
+   head_repo_url=$(gh pr view <PR> --json headRepository --jq .headRepository.url)
+   ```
+
+3) Fast-forward base:
+   - `git checkout main`
+   - `git pull --ff-only`
+4) Create temp base branch from main:
+   - `git checkout -b temp/landpr-<ts-or-pr>`
+5) Check out PR branch locally:
+   - `gh pr checkout <PR>`
+6) Rebase PR branch onto temp base:
+   - `git rebase temp/landpr-<ts-or-pr>`
+   - Fix conflicts; keep history tidy.
+7) Fix + tests + changelog:
+   - Implement fixes + add/adjust tests
+   - Update `CHANGELOG.md` and mention `#<PR>` + `@$contrib`
+8) Decide merge strategy:
+   - Rebase if we want to preserve commit history
+   - Squash if we want a single clean commit
+   - If unclear, ask
+9) Full gate (BEFORE commit):
+   - `pnpm lint && pnpm build && pnpm test`
+10) Commit via committer (include # + contributor in commit message):
+   - `committer "fix: <summary> (#<PR>) (thanks @$contrib)" CHANGELOG.md <changed files>`
+   - `land_sha=$(git rev-parse HEAD)`
+11) Push updated PR branch (rebase => usually needs force):
+
+   ```sh
+   git remote add prhead "$head_repo_url.git" 2>/dev/null || git remote set-url prhead "$head_repo_url.git"
+   git push --force-with-lease prhead HEAD:$head
+   ```
+
+12) Merge PR (must show MERGED on GitHub):
+   - Rebase: `gh pr merge <PR> --rebase`
+   - Squash: `gh pr merge <PR> --squash`
+   - Never `gh pr close` (closing is wrong)
+13) Sync main:
+   - `git checkout main`
+   - `git pull --ff-only`
+14) Comment on PR with what we did + SHAs + thanks **only with explicit user approval**:
+
+   ```sh
+   merge_sha=$(gh pr view <PR> --json mergeCommit --jq '.mergeCommit.oid')
+   gh pr comment <PR> --body "Landed via temp rebase onto main.\n\n- Gate: pnpm lint && pnpm build && pnpm test\n- Land commit: $land_sha\n- Merge commit: $merge_sha\n\nThanks @$contrib!"
+   ```
+
+15) Verify PR state == MERGED:
+   - `gh pr view <PR> --json state --jq .state`
+16) Delete temp branch:
+   - `git branch -D temp/landpr-<ts-or-pr>`
