scopewalker-mcp: Skill for Claude Code

.claude/skills/review-changes/SKILL.md

review-changes is a skill for Claude Code from timohaa/scopewalker-mcp. It costs 38 tokens per session (511 once invoked), scanned A, original, MIT.

A code-review workflow for checking uncommitted changes or the entire codebase against project standards. It includes automated checks for style, types, formatting, tests, and code-quality issues.

In plain words
What is it for?
Use it to review the working tree, run the project's quality checks, inspect changed files, and report failures with file and line details.
Why use it?
It catches problems before code is committed, including issues that automated checks may miss in new or changed files.

Skill for Claude Code

Written for Claude Code: installed under .claude/.

This is timohaa/scopewalker-mcp's own configuration. It tells Claude Code how to work on scopewalker-mcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything scopewalker-mcp configures →

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

review-changes 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 4d 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

Review Changes

Review all uncommitted changes against project standards before committing.

Scope

Default: uncommitted changes (the workflow below). If invoked with full, skip steps 1–2 and run the whole-codebase checks instead:

npm run check          # check:versions + lint:fix + typecheck
npx prettier --check src
npm run test

Then check_thresholds and get_code_smells on src/, and report a pass/fail summary per category (lint, types, format, tests, thresholds) with issue counts and file:line details for each failure. Skip the diff-based manual review.

Workflow

1. Get changed files

git status --porcelain

Covers modified, staged, and untracked files; untracked new files must be reviewed too, or the missing-tests/missing-docs checks below can't catch them.

2. Review the diff

git diff
git diff --cached

3. Run automated checks

npm run check
npm run test

Use check_thresholds and get_code_smells on changed files.

4. Manual review

Check for issues automation misses. The first three are mechanical markers; find them with one batched search across the whole changed-file list (e.g. a single grep -nE 'eslint-disable|@ts-ignore|console\.log' <files>, plus a pass over the diff you already have for commented-out code), not one search per file. The last two need judgment; read the changed files for those.

  • eslint-disable or @ts-ignore added without justification
  • console.log left in (use structured error handling)
  • Commented-out dead code
  • New functionality missing corresponding tests
  • New/changed tools missing documentation updates in TOOLS.md and docs/

5. Report

List issues grouped by severity:

  • Must fix: Standards violations, bugs, missing tests
  • Should fix: Style issues, minor improvements
  • Consider: Suggestions, optional improvements

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.
