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 | $0.02165 | $0.02165 |
| Opus 5 | $0.01082 | $0.01082 |
| Sonnet 5 | $0.00433 | $0.00433 |
| Haiku 4.5 | $0.00216 | $0.00216 |
Grade C, and why
agentic-design-system CLAUDE.md scanned grade C with 2 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 8d 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.
Reads agent configuration directoriesmediumAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

Other skills' SKILL.md files reveal prompts, capabilities and secrets that should be invisible to peers.

Agentic Design System — Agent Instructions
This is a monorepo for a React design system purpose-built for agentic/MCP applications. Read this file before making any changes.
Packages
| Package | Purpose |
|---|---|
packages/component-doc |
Types-only schema (ComponentDoc) for colocated component spec docs |
packages/tokens |
Design tokens — source of truth for all values |
packages/core |
Base components (Button, CodeBlock, AgenticProvider, theme) |
packages/agents |
Agent-specific components (streaming, tool calls, status) |
packages/mcp-builder |
MCP stdio server (get_token, get_component, search) + IIFE bundle for MCP App iframes |
apps/storybook |
Visual regression tests and component stories |
apps/demo-web |
Integration demo |
Build order is enforced: component-doc → tokens → core → agents → mcp-builder. Always run npm run build from the root.
Best Practices
Before implementing or modifying any component, read docs/best-practices.md. It is the authoritative standard for this codebase. Key rules summarized below.
Accessibility — Non-Negotiable
All components must meet WCAG 2.2 AA. Agent-specific components have specific ARIA requirements:

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.

agentic-design-system CLAUDE.md is an instructions file published in the GitHub repository brianmontanaweb/agentic-design-system (3 stars, last pushed 19d ago), licensed MIT. It adds 2,165 tokens to every session, about $0.0108 per session on Opus 5. A static security scan graded it C with 2 findings (reads agent configuration directories, enumerates other installed skills). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
