user-critic

user-critic is a skill for Claude Code, Codex from in-the-loop-labs/pair-review. It costs 56 tokens per session (351 once invoked), scanned A, original, Apache-2.0.

A workflow for retrieving human review comments from pair-review and changing code to address them. It handles comments from either a local review or a GitHub pull request.

In plain words
What is it for?
Use it after a human asks you to address review feedback, fix review comments, or respond to comments on the current code.
Why use it?
It turns scattered reviewer feedback into a concrete set of code changes and explanations, reducing the chance that a comment is missed.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

user-critic scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Address Review Feedback

Fetch human-curated review comments from pair-review and make code changes to address each one.

Determine review context

Determine whether this is a local review or a PR review:

  1. If the user explicitly says "local", use local mode.
  2. Otherwise, determine the GitHub owner, repo, and PR number for the current branch. If a PR exists, use PR mode with repo and prNumber params.
  3. If no PR exists, use local mode with path (absolute cwd) and headSha (git rev-parse HEAD) params.

Fetch comments

Call mcp__pair-review__get_user_comments with the review context params.

If no comments are returned, tell the user there's nothing to address.

Address each comment

For each comment returned:

  1. Read the file at the referenced path and lines.
  2. Understand what the reviewer is asking for — it may be a bug fix, a refactoring request, a question, or a style change.
  3. Make the code change that addresses the feedback.
  4. If the comment is a question or unclear, explain your interpretation and what you changed.

Report

After addressing all comments, provide a summary:

  • Which files were changed
  • What was done for each comment
  • Any comments that were ambiguous or could not be addressed (explain why)
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
