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-checklist 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 8d 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.

Code Review Checklist

Before you start

Gather the following from the reviewer or PR author. If anything is missing, ask before proceeding:

  1. What does the PR do? — The specific change, not "fixes stuff"
  2. Why is it needed? — Link to ticket, bug report, or requirement
  3. What is the blast radius? — Which systems, APIs, or users are affected
  4. Are there tests? — New, modified, or explicitly skipped (with justification)
  5. Is there a deploy plan? — Feature flag, migration, rollback strategy

Review template

1. First Pass: Understand Intent

Read the PR description and linked ticket before touching code. Answer:

  • What is the expected behavior change?
  • What should NOT change?
  • Are there edge cases called out by the author?

If the PR description is empty or vague, stop and request one. Reviewing code without context produces shallow feedback.

2. Correctness

Check each item:

  • Logic matches the stated requirement — not just "runs without errors"
  • Edge cases are handled: empty inputs, null values, boundary conditions, concurrent access
  • Error paths return meaningful messages, not silent failures or generic 500s
  • State mutations are atomic where required — no partial updates on failure
  • Data types are correct: string vs number, nullable vs required, timezone-aware dates

3. Security

  • User input is validated and sanitized before use
  • Authentication and authorization checks are present on new endpoints
  • Secrets are not hardcoded or logged — check for API keys, tokens, passwords
  • SQL queries use parameterized statements, not string concatenation
  • File uploads validate type, size, and content — not just extension
  • CORS, CSP, and rate limiting are configured for new routes

4. Performance

  • Database queries use indexes — check for full table scans on large tables
  • N+1 queries are eliminated — look for loops that issue individual queries
  • Large datasets are paginated, not loaded entirely into memory
  • Expensive computations are cached or debounced where appropriate
  • New API endpoints have timeout and retry policies defined

What ships with it

3 files 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.
