What is protocol-launcher CLAUDE.md?

A short guide for protocol-launcher that tells Claude, an AI coding assistant, how to follow the project's instructions. It points Claude to AGENTS.md and sets expectations for small changes, refactors, and verification.

Use it to find the applicable project instructions, account for nested instructions, plan larger refactors, and run the relevant pnpm or Turbo checks.

It gives Claude a clear entry point and helps keep changes reviewable and checked with the project's package-manager commands.

Token cost

What it costs to keep this loaded

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	$0.00115	$0.00115
Opus 5.5	$0.00046	$0.00046
Sonnet 5.5	$0.00023	$0.00023

Security

Grade A, and why

protocol-launcher 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 2mo 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.

CLAUDE.md · 13 lines

What it actually says

CLAUDE.md - Protocol Launcher

Use AGENTS.md as the primary project instruction file.

When working in a subdirectory, also follow the nearest nested AGENTS.md before making changes.

Claude-Specific Behavior

Prefer small, reviewable changes.
Before large refactors, summarize the impact and likely touched workspaces.
After code changes, run the most relevant pnpm/Turbo checks from AGENTS.md.
Keep shared repo guidance in AGENTS.md; keep this file as a lightweight Claude entrypoint.

Changes

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.
