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.

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 | $0.00281 | $0.00281 |
| Opus 5 | $0.00140 | $0.00140 |
| Sonnet 5 | $0.00056 | $0.00056 |
| Haiku 4.5 | $0.00028 | $0.00028 |
Grade A, and why
component-architecture 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 2d 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
Component Architecture
Matters Web follows a component-based architecture using React and Next.js.
Component Organization
Reusable components are organized in the src/components/ directory, each in its own folder with the following structure:
ComponentName/
├── index.tsx # Main component export
├── styles.module.css # Component styles
├── gql.ts # GraphQL queries/mutations (if needed)
└── ComponentName.test.tsx # Component tests
Component Types
- UI Components: Pure presentational components
- Compositions Components: Components that are built on top of other UI components and may include GraphQL fragments as part of their UI requirements
Key Component Directories
- src/components/Layout: Page layout components
- src/components/Form: Form input components
- src/components/Button: Button components
- src/components/Dialog: Modal dialog components
- src/components/GlobalDialogs: App-wide dialogs
- src/components/GlobalToasts: Toast notification system
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.
