agentic-coding: Skill for Claude Code

.agents/skills/agent-review/SKILL.md

agent-review is a skill for Claude Code from sflandergan/agentic-coding. It costs 22 tokens per session (842 once invoked), scanned A, original, MIT.

A review checklist for plans and code changes in a toolkit repository, based on the rules in its AGENTS.md file.

In plain words
What is it for?
Use it to review implementation plans or diffs for requirements coverage, lockfiles, documentation, shell scripts, symlinks, and commit conventions.
Why use it?
It helps catch missing files, broken links, outdated lists, unsafe Git actions, and missing verification before changes are accepted.

Skill for Claude Code

Written for Claude Code: user-invocable in frontmatter. Also seen: reads .claude/ paths; installed under .agents/ (shared by several agents); mentions AGENTS.md.

This is sflandergan/agentic-coding's own configuration. It tells Claude Code how to work on agentic-coding 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 agentic-coding configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is bash .agents/skills/github-pr-comments/scripts/fetch-pr-comments.sh [<pr>].

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

agent-review 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 2mo 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.

Agent Review — Self-Maintenance

Review plans and diffs against the conventions in AGENTS.md.

Review Checklist

For plans

  • If spec is present, check coverage: every requirement has a task
  • File mapping includes core/stack ripple check
  • Sync invariants addressed (README, lockfiles, dot-mapping)
  • No placeholders (TBD, TODO, "similar to Task N")
  • Verification commands included per task
  • Task boundaries produce one commit each

For diffs

  • Changes match the approved plan
  • SKILL.md frontmatter has name and description
  • Agent .md has description in frontmatter
  • Symlinks in .claude/skills/ resolve correctly
  • skills-lock.json reflects this repo's self-maintenance skills
  • core/skills-lock.json reflects target-project template skills
  • README agent/skill lists match actual files
  • Shell scripts pass shellcheck and bash -n
  • No force-push, no branch deletion, no worktree removal
  • Commits are concise, imperative, scoped to one logical change
  • No Co-Authored-By lines

Review Priorities

  1. Bugs, broken scripts, incorrect symlinks
  2. Missing sync: README vs files, lockfiles vs installed skills
  3. Convention violations from AGENTS.md
  4. Unnecessary scope expansion

PR Comment Review

Use the github-pr-comments skill and run:

bash .agents/skills/github-pr-comments/scripts/fetch-pr-comments.sh [<pr>]

Inline comments must be checked against the current diff before accepting or dismissing them. Outdated inline comments may still be valid; verify technical claims before dismissing.

Required Workflow

Use this standard self-maintenance review workflow unless the user explicitly requests a different scope:

  1. Read open PR comments first by using the github-pr-comments skill. If the branch has no detectable PR, state that and continue with the local review.
  2. Identify whether the review target is a spec/plan or a diff. If multiple candidate plans exist and the user did not state which one to use, ask before continuing the plan-conformance part of the review.
  3. Review the target yourself against AGENTS.md, repository conventions, sync invariants, and any approved spec or plan.
  4. Combine PR comments, user notes, external notes, and your own findings into one deduplicated list of actionable issues.
  5. Present suggested fixes as blocking issues and advisory suggestions first. Do not edit files yet.
  6. For approved spec/plan review fixes, update the reviewed spec or plan directly under plans/**.
  7. For approved diff review fixes that need planning or exceed trivial review-scoped changes, write a review-finding implementation plan next to the original plan, for example plans/<feature-dir>/review-findings.md. Do not adapt an unrelated implementation plan for new review findings, and do not create a new date-prefixed folder for review findings when an original plan exists.
  8. After plan updates or review-finding plan creation, self-review every tracked remark and finding. Map each item to the changed section, review-finding plan section, or intentional unresolved status.
  9. Draft exact GitHub replies for resolved PR comments and ask for explicit approval before posting. Approval to edit files or write a plan does not authorize posting GitHub comments.

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.
