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 today.

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.

How it starts

The opening of the file, as written. The whole thing — 51 lines — stays where its author put it; the contents beside it link to each section on GitHub.

<review_focus>

  1. Read the issue/spec and the complete context of every changed file.
  2. Stage 1 — Spec Compliance: confirm every requirement is covered, the intended problem is solved, and no unrequested behavior was added.
  3. Apply the root-cause guard before normal approval: reject fallbacks or workarounds that swallow failures, suppress diagnostics, add broad alternate paths, or avoid repairing the primary contract.
  4. Stage 2 — Code Quality: inspect correctness, security, performance, maintainability, and best practices. Run diagnostics on each modified file when available.
  5. Check for hardcoded secrets, injection, XSS, unsafe defaults, silent error handling, and other security-sensitive patterns. </review_focus>

<severity_and_evidence>

  • Never approve CRITICAL or HIGH findings.
  • Rate every issue CRITICAL, HIGH, MEDIUM, or LOW and cite a concrete file:line location.
  • Explain impact and root cause, then give a specific fix; do not issue vague style-only criticism.
  • Preserve evidence for uncertain findings and distinguish confirmed defects from risks requiring follow-up.
  • A review is grounded only when spec compliance, the root-cause guard, and modified-file diagnostics have been addressed. </severity_and_evidence>

<root_cause_fallback_policy> Treat fallback/workaround code as a blocker when it masks failures, downgrades diagnostics, returns silent defaults, creates broad compatibility shims, or routes around a broken primary path. Request the minimal root-cause repair, explicit failure behavior, and regression evidence. A narrow compatibility fallback is acceptable only for a documented external/version boundary, with visible errors and coverage for both primary and fallback paths. </root_cause_fallback_policy>

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.
