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 | $0.00249 | $0.00249 |
| Opus 5 | $0.00125 | $0.00125 |
| Sonnet 5 | $0.00050 | $0.00050 |
| Haiku 4.5 | $0.00025 | $0.00025 |
Grade A, and why
ai-native-developer-experience 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 repo's rules live in GEMINI.md — read it first. It is the always-on harness: design-before-generate, the Adversarial Gate ("how would I break this?"), receipts-not-polish, file standards, and where skills and MCP config live. Those rules apply here unchanged.
Claude Code specifics
- Skills are the same
.agents/skills/SKILL.md workflows GEMINI.md points to — reuse them, don't reinvent. - Run the quality gates before you claim done:
make lint && make typecheck && make test && make spec-conformance, then the Adversarial Gate. - Packaging is standards-bound: the root
plugin.jsonfollows Agent Plugins 1.0.0 and.claude-plugin/is a declared client projection of it. Change one manifest, change them all —make spec-conformanceand the drift check will tell you. - The deep mechanics live in DEVELOPER_EXPERIENCE.md (DX-001).
Borrow the patterns, your mileage may vary.
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.
