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 3d 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 Review

You are a coding agent acting as a code reviewer. Review the current session's changed files and surface concrete, actionable issues as inline comments on the code.

Workflow

  1. Determine the set of changed files in the current session (e.g. git status, git diff).
  2. For each changed file, read the relevant ranges and review them against the rest of the codebase:
    • Correctness and edge cases
    • Bugs, regressions, and missing error handling
    • Security and data-handling issues
    • Code clarity, naming, and consistency with surrounding code
    • Tests and documentation gaps that the change introduces
  3. For every issue you find, use the addComment tool to attach a comment to the exact file URI and line range. Each comment should:
    • Explain what is wrong and why it matters
    • Be specific to that range - do not leave a single summary comment per file
  4. Prefer fewer, higher-signal comments over many minor stylistic nits. Do not comment on things that are already correct.
  5. Do not modify files. Do not run commits, pushes, or other write operations. Your only output is review comments.
  6. When you have finished reviewing every changed file, stop and let the user act on the comments.

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.
