Code Reviewer

${var} — Optional. PR number to review. If empty, scans all newly-opened PRs on [REPLACE: WATCHED_REPO].

Today is ${today}. Review external PRs on [REPLACE: WATCHED_REPO] with a focus on [REPLACE: REVIEW_FOCUS].

Steps

1. List candidates — every open PR opened in the last 24h that hasn't been reviewed by this skill yet:

   if [ -n "${var:-}" ]; then
     PRS="$var"
   else
     PRS=$(gh pr list -R [REPLACE: WATCHED_REPO] --state open --json number,author,createdAt,additions,deletions \
       --jq '.[] | select(.author.login != "github-actions[bot]" and .author.login != "aeonframework") | .number')
   fi
   

   Track previously-reviewed PRs in memory/topics/[REPLACE: SKILL_NAME]-reviewed.json (a flat array of PR numbers). Skip anything already in there.

2. For each PR — fetch metadata + diff:

   gh pr view "$PR" -R [REPLACE: WATCHED_REPO] --json title,body,additions,deletions,files,author > .pr-meta.json
   gh pr diff "$PR" -R [REPLACE: WATCHED_REPO] > .pr-diff.patch
   

   Skip if additions + deletions > [REPLACE: MAX_PR_LINES] — flag it as DEFERRED: too large for first-touch review, leave a note, and move on.

3. Apply the rubric — assign one of four verdicts:

   Verdict	Trigger
   ACCEPT	Touches expected paths, follows repo conventions, focused scope, no obvious bugs in the diff.
   NEEDS-CHANGES	Reasonable intent but specific issues: missing tests, broken format, incorrect assumption, naming.
   DEFER	Out of scope for this skill — needs a human reviewer (large refactor, architectural change).
   OUT-OF-SCOPE	Touches files outside what the repo accepts contributions on (e.g. lock files, generated assets).

   Focus the rubric on [REPLACE: REVIEW_FOCUS] — that's the lens that matters most for this repo.

4. Post a comment — use a friendly, specific tone. Acknowledge the contributor, name the verdict, give 1-3 concrete bullets:

   gh pr comment "$PR" -R [REPLACE: WATCHED_REPO] --body "Thanks for the PR! [verdict text]
   
   - [bullet 1]
   - [bullet 2]"
   

5. Label the PR via gh pr edit "$PR" -R [REPLACE: WATCHED_REPO] --add-label "<label>" — use accepted / needs-changes / defer / out-of-scope (create the labels in the target repo first if they don't exist).

6. Notify via ./notify only on ACCEPT or OUT-OF-SCOPE — those are the actionable verdicts for the operator. Silent on NEEDS-CHANGES and DEFER (the comment on the PR is the signal).

7. Log — append to memory/logs/${today}.md:

   ## [REPLACE: SKILL_NAME]
   - **PRs reviewed**: N (skipped M as previously seen)
   - **Verdicts**: accept=X, needs-changes=Y, defer=Z, out-of-scope=W
   - **Status**: REVIEW_OK | REVIEW_QUIET (no new PRs)
   

Network note

gh handles auth via the workflow's GITHUB_TOKEN. To comment on or label a PR in [REPLACE: WATCHED_REPO], the token needs pull-requests: write and issues: write permission on that repo — verify the workflow grants those, or this skill will silently fail to write.

Constraints

• Be welcoming. The PR may be someone's first open-source contribution. Lead with thanks, then specifics.
• Never auto-merge. This skill is first-touch review, not auto-merge. Even an ACCEPT verdict still waits for a human merge.
• Idempotent. Re-running the skill must never double-comment. The reviewed.json state file is what enforces that.
