agent-kernel CLAUDE.md

A short instruction file for contributors to the Agent Kernel codebase, directing them to the main AGENTS.md guide and the repository's development skills.

In plain words
What is it for?
It helps Claude Code begin work in the repository with the correct documentation, commands, and conventions.
Why use it?
It prevents contributors from missing the repository map, setup commands, testing rules, and the difference between developer tools and tools shipped to package users.

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.

Security

Grade A, and why

agent-kernel 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 3d 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

See AGENTS.md — it has the full guide for working on this repo (repo map, setup/lint/test commands, the dev-skills-vs-bundled-skills distinction, and conventions). Read it before making changes.

Claude Code specifically: the dev skills under .agents/skills/ (ak-dev-architecture, ak-dev-testing-conventions, ak-dev-new-*, etc.) are already registered — invoke them via the Skill tool instead of re-deriving that context from scratch.

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.
