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 | $0.00394 | $0.00394 |
| Opus 5 | $0.00197 | $0.00197 |
| Sonnet 5 | $0.00079 | $0.00079 |
| Haiku 4.5 | $0.00039 | $0.00039 |
Grade A, and why
claude-code-starter CLAUDE.md 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 5d 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
CLAUDE.md
This file is loaded into every Claude Code session. It is your project's rulebook. Keep it short (under ~200 lines) and dense. Replace the placeholders below with your own project's details.
Project
One-line description of what this app does. Domain / production URL goes here.
Principles
- Production-ready from day one. No placeholders, no TODOs left behind.
- Follow the existing patterns in the codebase. Read before you write.
- One change at a time. Show it working before moving on.
Tech stack
- Framework: (e.g. Next.js / your framework)
- Language: (e.g. TypeScript strict)
- Styling / UI: (e.g. Tailwind + your component library)
- Backend / data: (your database + services)
- Testing: (your unit + e2e tools)
Commands
npm run dev # start the dev server
npm run build # production build
npm run lint # linter
npm test # tests
Conventions
- Icons: pick ONE icon library and stick to it.
- Dark mode and light mode must both work.
- Never commit secrets. They live in
.env.local(gitignored). - Commit format:
PROJ-XXX: short description. Commit after every change.
Rules that load on demand
Path-scoped rules live in .claude/rules/. They only load when Claude touches
a matching file, so this CLAUDE.md stays lean:
rules/api.mdloads forapp/api/**
Hard rules
- IMPORTANT: never push to
mainwithout an explicit ask. Branch first. - IMPORTANT: when asked to deploy, the pre-deploy guard runs your tests first and blocks the deploy if anything is red. Fix tests before shipping.
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.
