What is agents-md-optimizer?

A coding-agent add-on for auditing, rewriting, or creating CLAUDE.md and AGENTS.md instruction files. These files tell an agent how to work in a project.

Use it when setting up project instructions, reducing a bloated file, or organizing guidance across project and user locations.

Overloaded instruction files use context space and can hide the rules that matter most. This helps remove copied documentation, tutorials, and unnecessary preloaded information.

Security

Grade A, and why

agents-md-optimizer 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 2d 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 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.

A memory lifecycle for Claude Code's native file-based memory: a save gate against hallucinated memories, tiered expiry (short-tier memories archived — never deleted — when they lapse), a propose-then-confirm consolidation pass (merge/dedupe long-tier memory), a periodic learning-review nudge, a two-file habit frame…
