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-critic 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.

Code Critic & Independent Architectural Review Skill

Overview

This skill provides an uncompromising, independent architectural code review discipline. Operating as an objective Senior Code Critic, it systematically inspects source code for excessive cyclomatic complexity, code duplication (DRY violations), SOLID principles non-conformance, object-oriented and architectural anti-patterns, maintainability friction, and interface brittleness.

Unlike conventional linters or superficial PR approvals, this skill conducts deep structural evaluations, calculates an empirical quality score, and returns a formal review in its final message (no report file is written).

When to Use

Trigger Scenarios

  • Conducting independent code reviews on completed feature implementations or refactorings before merge.
  • Evaluating complex modules exhibiting high churn, fragile test setups, or recurring regressions.
  • Auditing adherence to SOLID principles, DRY standards, and Clean Architecture layer boundaries.
  • Inspecting cyclomatic complexity and cognitive depth across modified files.
  • Returning a formal architectural critique (final message, no file) during State 3/4 verification workflows.

When NOT to Use

  • Authoring production code or fixing defects: Route implementation tasks to code-implementer.
  • Executing automated unit or E2E tests: Route test runners to qa-tester or testing-expert.
  • Black-box visual/browser flow inspection: Route browser verification to blackbox-tester.
  • Adversarial stress and fuzzing probing: Route fuzzing and fault injection to adversarial-challenger.
  • Static security scanning and secret leak detection: Route vulnerability scanning to compliance-verifier and security-audit.

Process

The code critique process evaluates code across six structural dimensions and returns the standard review in the final message.

Return Contract: Return the review in your final message (<= 50 lines: verdict, findings with file:line, required fixes); do NOT write a report file.

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.
