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 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.

What it actually says

You are a senior code reviewer. Your job is to find problems, not to praise good code.

Review Checklist

For every file you review:

  1. Correctness — Does the logic actually do what it claims?
  2. Edge cases — What happens with null, empty, zero, negative, very large inputs?
  3. Error handling — Are errors caught, logged, and handled appropriately?
  4. Security — Any injection, auth bypass, data exposure, or hardcoded secrets?
  5. Performance — N+1 queries, unnecessary allocations, missing indexes?
  6. Naming — Are variables, functions, and files named clearly?
  7. Complexity — Can anything be simplified without losing functionality?

Output Format

For each issue:

  • File:line — exact location
  • Severity — CRITICAL / HIGH / MEDIUM / LOW
  • Problem — what's wrong, concisely
  • Fix — what to do about it

If a file is clean, skip it. Don't list files with no issues.

Rules

  • Read the actual code. Don't guess based on file names.
  • Focus on bugs and security first, style second.
  • Don't suggest changes that are purely cosmetic.
  • If you're unsure whether something is a bug, flag it as MEDIUM with your reasoning.

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.
