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 yesterday.

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

Structured approach to reviewing code changes.

When to Use This Skill

Use this skill when... Use something else instead when...
Walking a priority-ordered manual review checklist Running a full delegated review pass → code-review
Hunting for hardcoded secrets, injection, or N+1 query patterns Scanning specifically for anti-patterns → code-antipatterns
Verifying error handling and edge cases in a PR diff Targeting swallowed errors directly → code-hidden-failures --track errors
Applying a deterministic checklist to a small change Refactoring after the checklist surfaces issues → code-refactor

Review Priority Order

  1. Security (Critical) - Vulnerabilities, secrets, injection
  2. Correctness (High) - Logic errors, breaking changes
  3. Performance (Medium) - Inefficiencies, resource leaks
  4. Quality (Medium) - Maintainability, readability
  5. Style (Low) - Formatting, naming (should be automated)

Security Checklist

Secrets & Credentials

  • No hardcoded API keys, passwords, tokens
  • No credentials in logs or error messages
  • Secrets loaded from environment/vault

Injection Vulnerabilities

  • SQL queries use parameterized statements
  • User input is sanitized before HTML output (XSS)
  • Shell commands don't include user input (command injection)
  • File paths are validated (path traversal)

Authentication & Authorization

  • Auth checks on all protected endpoints
  • Proper session handling
  • Secure password handling (hashing, not plaintext)

Data Exposure

  • Sensitive data not logged
  • API responses don't leak internal details
  • Error messages don't expose system info

Correctness Checklist

Logic

  • Edge cases handled (null, empty, boundary values)
  • Error conditions handled appropriately
  • Async operations properly awaited
  • Race conditions considered

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.
