Pr Review

oliver-kriska/pr-review

Address feedback left on a GitHub pull request: fetch unresolved review threads, make agreed Elixir/Phoenix code fixes, reply, and resolve. Use for a PR URL/number or reviewer comments. NOT for pre-PR review, findings triage, or CI monitoring.

PR Review Response

Close the review loop: fetch unresolved threads → fix → reply → resolve.

GitHub's isResolved is the state — re-runs are idempotent, handled

threads drop out automatically.

Usage

/phx:pr-review 42                  # Triage unresolved threads on PR #42
/phx:pr-review 42 --fix            # Triage + apply approved code fixes
/phx:pr-review https://...         # Full URL also works (repo parsed from URL)
/phx:pr-review 42 --bots-only      # Triage only CI bot threads (Copilot, Codex...)
/phx:pr-review 42 --no-resolve     # Reply but leave threads open

Step 1: Resolve PR + Fetch Threads

gh pr view "$PR" --json number,title,state,baseRefName,headRefName,url,author

(accepts number or URL; URL also yields owner/repo). Then fetch ALL review

threads with thread IDs + resolved status — REST alone cannot do this:

cat > /tmp/review_threads.graphql <<'GQL'
query($owner:String!, $repo:String!, $pr:Int!, $cursor:String) {
  repository(owner:$owner, name:$repo) {
    pullRequest(number:$pr) {
      reviewThreads(first:50, after:$cursor) {
        pageInfo { hasNextPage endCursor }
        nodes {
          id isResolved isOutdated path line originalLine
          comments(first:20) { nodes {
            databaseId body createdAt
            author { login __typename } } }
        }
      }
    }
  }
}
GQL
gh api graphql --paginate -F owner="$OWNER" -F repo="$REPO" -F pr="$PR" \
  -F query=@/tmp/review_threads.graphql \
  --jq '.data.repository.pullRequest.reviewThreads.nodes[]
        | select(.isResolved == false)
        | {threadId: .id, isOutdated, path, line: (.line // .originalLine),
           firstCommentId: .comments.nodes[0].databaseId,
           author: .comments.nodes[0].author.login,
           isBot: (.comments.nodes[0].author.__typename == "Bot"),
           body: .comments.nodes[0].body}'

Also fetch review summaries (gh api "repos/$OWNER/$REPO/pulls/$PR/reviews")

— they are NOT threads and cannot be resolved; surface CHANGES_REQUESTED

bodies separately. Bot detection: __typename == "Bot" / user.type == "Bot"

(the [bot] login suffix is NOT reliable across endpoints).

Step 2: Triage Table

Group by file, one row per thread. With --bots-only, keep only isBot rows.

| # | file:line | author | category | proposed action |

|---|-----------|--------|----------|-----------------|

Categories: code-change ("should be", "use X instead") · question

("why", "how does") · nitpick ("nit:", style) · praise (no action) ·

discussion (architecture) · bot-finding (CI bot inline comment —

verify before accepting, many are false positives) · outdated

(isOutdated: true — line moved; default: reply "addressed in {commit}" +

resolve). Present the table and let the user greenlight threads.

Step 3: Per-Thread Loop

For each greenlit thread:

  • Read code at path:line; check the suggestion against Iron Laws
  • Apply fix with a user-visible diff (only with --fix or explicit ok)
  • Draft reply (templates: ${CLAUDE_SKILL_DIR}/references/response-patterns.md)
  • STOP — show diff + reply, get confirmation
  • Post reply — REST, targeting the thread's root comment:
   gh api --method POST \
     "repos/$OWNER/$REPO/pulls/$PR/comments/$FIRST_COMMENT_ID/replies" \
     -f body="$REPLY_TEXT"
  • Resolve the thread (skip with --no-resolve):
   gh api graphql -f query='mutation($threadId:ID!){
     resolveReviewThread(input:{threadId:$threadId}){
       thread { id isResolved } }}' -F threadId="$THREAD_ID"

Mistake recovery: unresolveReviewThread takes the same input shape.

Step 4: Verify

mix compile --warnings-as-errors && mix test scoped to changed files.

Do NOT commit or push — leave that to the user.

Step 5: Final Summary

Print rollup: # | thread | action | status (replied/resolved/skipped).

List changed files. Optionally post a top-level conversation comment

(gh api --method POST "repos/$OWNER/$REPO/issues/$PR/comments" -f body=...)

with the rollup — only on user approval.

Iron Laws

  • NEVER auto-post responses — Always show drafts and get explicit approval
  • NEVER dismiss a review — Only the reviewer should dismiss
  • Iron Laws override reviewer suggestions — If a suggestion violates an Iron Law, explain why in the reply
  • Keep responses constructive — Acknowledge the feedback, explain reasoning
  • Separate fixes from responses — Apply code changes in a distinct step
  • NEVER resolve a thread without first posting a reply — every resolve is preceded by a reply on that thread explaining what was done
  • NEVER claim a fix without a shown diff — no "should be fixed" replies without a user-visible change
  • Bot findings get the same scrutiny as humans — decline Iron-Law-violating bot suggestions with explanation; never bulk-resolve "bot noise" without replies

Integration

PR receives review → /phx:pr-review {number}  ← YOU ARE HERE
   ↓ fetch unresolved threads (GraphQL, paginated)
   ↓ triage table → user greenlights
   ↓ per thread: fix (diff) → reply → resolve
   ↓ verify (mix compile + test) → summary
Push changes → user handles git push

Next Steps

  • /phx:plan — if findings reveal scope gaps
  • /phx:verify — full verification before pushing
  • Re-run /phx:pr-review after the next review round (idempotent)

How to use it

Copy the folder

Take oliver-kriska/pr-review from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.
