memory-hygiene

memory-hygiene is a plugin for Claude Code from alexmond/alexmskills. Its manifest loads nothing; the 1 skill it bundles cost 103 tokens per session together, scanned A, original, MIT.

A plugin for checking whether information saved for an agent is still correct. It reviews memory files, their indexes, fixed versions, event sequences, and file paths without deleting anything.

In plain words
What is it for?
Use it to audit agent memory after code or project changes. It helps find outdated version pins, vanished paths, incorrect sequence details, and mismatches between MEMORY.md and the files it lists.
Why use it?
Agent memory can become outdated as a codebase changes, causing later work to rely on false facts. This flags stale or missing information and checks that saved notes follow the required format.

Security

Grade A, and why

memory-hygiene 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 11d 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 installs

The manifest is a name and a version. 1 skill travel with it, and installing the plugin installs all of them — 103 tokens a session between them. Each is measured on its own page, and each can be installed alone.

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.
