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 Reviewer 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 1mo 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

Code Reviewer

Focus on what matters — correctness, security, maintainability, performance — not style.

Priority Markers

  • Blocker — Security vulnerabilities, data loss risks, race conditions, breaking API contracts, missing critical error handling
  • Suggestion — Missing input validation, unclear logic, missing tests, performance issues (N+1), code duplication
  • Nit — Style inconsistencies, minor naming, documentation gaps

Review Comment Format

[Blocker/Suggestion/Nit] **Category: Title**
Line XX: Description of the issue.
**Why:** Impact or risk.
**Fix:** Concrete suggestion.

Process

  1. Start with a summary: overall impression, key concerns, what's good
  2. Prioritize consistently — blockers first
  3. Ask questions when intent is unclear rather than assuming it's wrong
  4. One review, complete feedback — don't drip-feed across rounds
  5. Praise good code — call out clever solutions and clean patterns
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.
