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

code-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 today.

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.

How it starts

The opening of the file, as written. The whole thing — 81 lines — stays where its author put it; the contents beside it link to each section on GitHub.

CI code review (/review:code-review)

Org-owned review logic for the claude-review reusable workflow (ci-workflows#258). The lane's workflow wrapper supplies REPO / PR NUMBER / HEAD SHA and the event-class reporting mechanics (inline-comment MCP on pull_request, gh pr review/gh pr comment on workflow_dispatch). This skill owns what to look for; the wrapper owns how to post.

Gotchas

  • Command/skill frontmatter allowed-tools grants permission but does not install the inline-comment MCP server. That server only installs when named in the action's claude_args (--allowedTools mcp__github_inline_comment__create_inline_comment). Rely on the lane wrapper's grant; do not assume this frontmatter installed it.
  • Do not invent a 0–100 confidence-score gate. Prefer adversarial validation (producer ≠ verifier) when spawning subagents.
  • Scope security findings out of this lane wherever the consumer carries a claude-security-review workflow file. Leave those to /review:security-review.

Skip gate (cheap)

Before deep review, stop early when any of these hold (say so in the summary and post nothing else):

  1. PR is closed or not open
  2. PR is a draft
  3. Change is trivial/automated with no meaningful review surface
  4. This head already has a successful review from this lane that still applies

Criteria

This is the CODE-REVIEW lane. Review the pull request for correctness and alignment with the project's CLAUDE.md guidelines (and REVIEW.md criteria when present). Focus on architecture decisions, error handling, test coverage, and maintainability. Where REVIEW.md splits review scope across lanes. It scopes security review to the dedicated security lane wherever a claude-security-review workflow exists. Follow that split.

Scope the review to files changed in this PR. Use gh pr diff to identify what changed, then review those files. Do not explore unrelated parts of the codebase.

Never restate the PR author's own claimed verification (e.g. a Test plan's described commands or output) as evidence you independently confirmed. Only claim to have verified something you yourself ran with a tool available to you; label anything else as author-claimed and unverified.

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
