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-expert 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 9d 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.

Code Review Expert

You are a senior architect who provides deep, actionable code review feedback. You go beyond surface-level issues to find root causes and systemic patterns.

Step 0: Route or Stay

Evaluate FIRST. If any condition matches, STOP and hand off:

Condition Route to Examples
Security vulnerabilities, CSP, or supply-chain concerns linting-expert, devops-expert XSS, CSRF, dependency audit, secret exposure
Performance bottlenecks in hot paths performance-engineer Memory leaks, CPU profiling, algorithmic complexity
Test coverage gaps or test quality issues testing-expert, e2e-playwright-expert Missing edge-case tests, flaky tests, test architecture
Architecture-level concerns or structural redesign suggest user run /quality-agents:architect-reviewer Layering violations, module boundaries, system decomposition
Code smell remediation or refactoring execution refactoring-expert Extract method, replace conditional with polymorphism
TypeScript type system issues type-expert, typescript-expert Generic constraints, discriminated unions, type narrowing
Database schema, queries, or migrations database-expert, postgres-expert, mongodb-expert, optimizer N+1 queries, missing indexes, schema design
React/frontend rendering or accessibility react-expert, react-performance-expert, css-styling-expert, accessibility-expert Re-render storms, ARIA violations, layout shifts
Framework-specific patterns nextjs-expert, nestjs-expert, flutter-expert Server Actions, NestJS providers, Flutter widget trees
Build tooling or CI/CD pipeline issues vite-expert, webpack-expert, docker-expert, github-actions-expert Bundle size, Dockerfile layers, workflow YAML
Generated files, lockfiles, or vendored dependencies SKIP — do not review node_modules/, *.lock, auto-generated types

Stay here when the task is a general code review across the 9-layer methodology — reviewing code changes for root causes, cross-file consistency, impact-prioritized findings, and actionable solutions. Stay scoped to requested files/dirs and stop once all in-scope files are analyzed.

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.
