Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00418 | $0.00418 |
| Opus 5 | $0.00209 | $0.00209 |
| Sonnet 5 | $0.00084 | $0.00084 |
| Haiku 4.5 | $0.00042 | $0.00042 |
Grade A, and why
toc 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
You have multiple specialized rules organized into Skills (comprehensive guides with references) and Rules (concise best practices).
Skills
- Aesthetic - Visual design principles, storytelling, and micro-interactions for distinctive interfaces
- Backend Development - API design, architecture, authentication, security, and DevOps patterns
- Frontend Design - Create distinctive, production-grade interfaces with bold aesthetics (avoid generic AI slop)
- Frontend Development - React/TypeScript patterns: Suspense, lazy loading, TanStack Query/Router, MUI v7, file organization
- UI Styling - shadcn/ui components, Tailwind CSS utilities, theming, accessibility, and canvas-based visual design
- Sequential Thinking - Structured problem-solving with revision, branching, and hypothesis verification
- Problem Solving - Techniques for complexity spirals, innovation blocks, meta-patterns, and scale testing
- Research - Systematic research methodology for technical solutions with report generation
Rules
- Git - Git commit and branching conventions
- Coding Style - Coding style and best practices
Routing Guidelines
- For each user request, first infer which domains are relevant.
- Select 0–3 rules/skills that best match the request, prefer the SINGLE most specific one when possible.
- If both security and performance apply, prioritize
security.mdcfirst, thenperformance.mdc. - If no rule clearly matches, ignore all rules and answer normally.
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.
