Process pr comments lite

Process PR / MR Review Comments — Lite

A stripped-down, autonomous take on process-pr-comments: given a PR/MR number, apply the review comments that are logically sound against the real code, record recurring feedback as rules, and stop. Nothing else.

For the full interactive workflow — batched per-comment approval, an implementation-plan gate, and a commit-suggest step — use process-pr-comments instead.

Rules

• No user input. Take the PR/MR number from the request. Never ask questions, never wait for approval, never gate on a plan.
• Never post to the forge and never commit. Edit files in the working tree only — leave staging and committing to the user.
• Only apply what's logically sound. Validate every comment against the actual code; silently skip anything that's already handled, outdated, or wrong.

Steps

1. Resolve & fetch

• Detect the forge from git remote get-url origin (github / gitlab / bitbucket) and use its CLI (gh / glab / bb), always passing the explicit PR number.
• Check out the PR's source branch if not already on it (git fetch first if the branch is missing).
• Fetch all unresolved comment threads, filtered to the needed fields (CLI --json/--jq). Walk each thread fully — the real request is often in a reply — and skip bot / system comments. If there are none, report "No unresolved comments on <PR|MR> #{n}." and stop.

2. Validate against the code

For each comment, Read the referenced code (inline: around the anchor line, ±~10 lines; general: locate the area) and decide whether the requested change is logically correct — a genuine fix or improvement that isn't already handled, outdated, or based on a misread. If a conventions file exists (AGENTS.md, CLAUDE.md, .github/copilot-instructions.md, .cursorrules), grep it for keywords relevant to the comment and read only the matched sections. Keep a one-line verdict per comment.

3. Implement the valid ones

Apply every comment that passed step 2 directly in the working tree, grouping edits by file. Skip the rest. Do not stage or commit.

4. Save the rules

Extract durable, checkable rules from what was applied — the underlying principle, not the one-off fix (e.g. "Composables accept modifier: Modifier = Modifier as the first optional parameter"). Append them to a cumulative docs/pr-review-rules.md (create it if missing), de-duped, under a PR-tagged heading. Add a one-line pointer to that file from the conventions file (priority AGENTS.md → CLAUDE.md → .github/copilot-instructions.md → cursor rules) if one isn't there already.

5. Report & stop

Print a short summary and end — no commit, no further steps:

• Applied — one line per implemented comment: path:line — <gist>.
• Skipped — one line per skipped comment: path:line — <one-line reason>.
• Rules — the rules written to docs/pr-review-rules.md.
