ClawHub PR Maintainer

Use this skill for maintainer-facing ClawHub GitHub workflow, not for ordinary implementation work.

Start With Live GitHub State

• Use gh pr view or gh issue view against openclaw/clawhub; verify live state before commenting, labeling, closing, or recommending merge.
• For PRs, read title, body, author, labels, comments, files, commits, status checks, review state, and linked issues.
• Surface author identity briefly: GitHub name/login and account age when useful. Treat identity as triage signal, never as proof by itself.

Common read-only commands:

gh pr view <number> --repo openclaw/clawhub --json title,body,author,labels,comments,files,commits,statusCheckRollup,reviewDecision,url,additions,deletions,changedFiles
gh issue view <number> --repo openclaw/clawhub --json title,body,author,labels,comments,state,url
gh api users/<login> --jq '{login,name,created_at,type}'

Review Evidence Bar

• For bug fixes, require symptom evidence, a plausible root cause in the touched code path, and either a regression test or focused manual proof.
• For UI changes, require screenshots or video when the behavior is meaningfully visual. Use tests as supplemental evidence, not a substitute for visible proof.
• Do not merge or recommend merge based only on PR prose, AI rationale, or green CI when the changed behavior has not been exercised.
• For contributor-provided screenshots/videos/logs, inspect the artifact directly and state what it proves. Do not rerun proof:ui just to inspect existing evidence.

Structure PR Review Output

• Start every PR review with 1-3 plain sentences explaining what the change does and why it matters.
• Show size near the top as LOC: +x/-y (N files), using live PR stats or local diff stats.
• Then list findings first. If none, say No blocking findings or No findings.
• Always answer: affected ClawHub surface, bug or behavior being changed, evidence checked, and best-fix verdict.
• For bug/regression fixes, include a compact Provenance: line when a bounded history pass identifies it. Separate code author, PR author, merger/committer, current PR author, PR number, and date when those differ. If the blamed PR was merged by automation, identify the human trigger when practical; otherwise say trigger unknown.

Read Beyond The Diff

• For code-path bug, regression, or behavior changes, review the surrounding path, not just changed lines. Open the runtime entry point, owner module, one caller, one callee, adjacent tests, and sibling surfaces that should share the invariant.
• For docs/config/process-only changes, read the changed file, its linked or adjacent source of truth, and any route/workflow/template the change claims to affect. Do not require runtime caller/callee evidence when no runtime path exists.
• Compare against current origin/main behavior or current published docs when regression, compatibility, or user-visible docs accuracy matters.
• For dependency-backed behavior, read the upstream docs/source/types before judging API use, defaults, output shapes, errors, timeouts, memory behavior, or compatibility.
• Mention the main files or contracts read when the verdict depends on code-path, docs, config, or workflow evidence.
• If a required path is uninspected, keep reading or mark Remaining uncertainty; do not call the PR best, proof-sufficient, or merge-ready.

Best-Fix Review Loop

Every PR review must explicitly answer: "Is this the best fix, or only a plausible fix?"

Before verdict:

1. Reconstruct the bug, feature need, or behavior claim from the issue, PR, and proof.
2. For code-path changes, trace current behavior from entry point to failure or decision point.
3. For docs/config/process-only changes, trace the reader/operator workflow or automation path the change is meant to clarify.
4. Read touched files, relevant callers/callees for code changes, adjacent docs or tests, owner modules, and relevant source-of-truth docs.
5. Read sibling surfaces that should share the invariant or could be broken by a one-sided fix.
6. Compare against current origin/main and shipped behavior when relevant.
7. Identify at least one alternative fix location or shape, then reject it with evidence.

Review output must include:

• Best-fix verdict: best / acceptable mitigation / wrong layer / too narrow / too broad.
• Alternatives considered: 1-3 concrete alternatives and why rejected.
• Code read: compact list of main files/contracts checked.
• Remaining uncertainty: what was not proven.

Enforce Bug-Fix Evidence

• Never merge a bug-fix PR based only on issue text, PR text, or AI rationale.
• Before recommending merge for a bug fix, require:
  1. symptom evidence such as a repro, logs, failing test, or focused manual proof
  2. a verified root cause in code with file/line
  3. blame-backed provenance for regressions when traceable, or commit SHA/date when no PR is traceable
  4. a fix that touches the implicated code path
  5. a regression test when feasible, or explicit manual verification plus a reason no test was added
• If the claim is unsubstantiated or likely wrong, request evidence or changes instead of recommending merge.

Decide UI Proof Mode

Use the clawhub-ui-proof skill when the maintainer/agent should generate new visual evidence.

• before-after: bug fixes, regressions, changed copy, changed layout, or any PR where main-vs-candidate comparison clarifies the change.
• feature: new page, new flow, new UI state, or behavior that cannot exist on origin/main.
• No generated proof: docs-only, backend-only, tests-only, metadata-only, or already-sufficient contributor evidence.

Write a temporary Playwright scenario under .artifacts/proof-scenarios/; do not infer manual clicks. Keep screenshots and videos in .artifacts/ until publishing. Never commit proof artifacts.

Final Review Comment With Proof

If this review generated proof:ui artifacts, publish them before the final PR review comment. Do not leave only local .artifacts/... paths in a PR comment; they are useful to the maintainer locally but invisible to GitHub readers.

Use:

bun run proof:publish -- --proof-dir .artifacts/clawhub-ui-proof/<timestamp> --target-pr <number>

proof:publish copies the selected files to the qa-artifacts branch and upserts a marker-backed PR comment with a ClawHub UI Proof section.

That comment includes:

• the proof mode (before-after or feature)
• the report.md result summary
• the most relevant per-step screenshots
• inline video previews when GIF previews are present
• links to full-run MP4s
• links to raw proof files on the artifact branch

Use --dry-run before publishing if you need to inspect the generated comment. If publishing fails because credentials are missing, report the local proof directory and the failed command instead of posting a comment that claims evidence is attached.

ClawSweeper

ClawSweeper is the bot control plane for automated PR/issue review once ClawHub dispatch is configured. Until then, use this skill for manual maintainer review. If ClawSweeper has posted a review, read it as evidence but verify live PR state before acting.

Commenting And Labels

• Use literal multiline comment bodies or --body-file; never pass escaped \n strings.
• For issue comments and PR comments containing backticks or shell characters, prefer a single-quoted heredoc or --body-file over inline -b bodies.
• Do not wrap issue or PR refs like #123 in backticks when you want GitHub to auto-link them.
• Keep maintainer comments short: finding, evidence, requested action, and verification path.
• When no proof artifacts were generated, gh pr comment --body-file is fine. When proof artifacts were generated, use proof:publish so screenshots/videos are published before posting.
• Do not close more than five issues/PRs in one action without explicit confirmation and the exact target list.
