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 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

Reviewing a change

Read the diff and report concrete, actionable findings. Prefer a few high-confidence issues over a long list of nitpicks.

Check, in order:

  1. Correctness — off-by-one errors, inverted conditions, unhandled None/ error paths, resource leaks, race conditions.
  2. Security — unvalidated input, injection, secret handling, unsafe defaults, missing authorization checks.
  3. Clarity & reuse — duplicated logic, dead code, names that mislead, functions that could reuse an existing helper.
  4. Tests — does the change ship coverage for its new behavior and edge cases?

For each finding, cite the file and line, state the impact, and propose a fix. Distinguish blocking issues from optional suggestions.

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.
