memory-hygiene SKILL.md skillA
memory-hygiene from chrono-meta/forge-harness is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add chrono-meta/forge-harness/memory-hygiene@git:20260811.eede7adPins git:20260811.eede7ad in mdr.lock. Pin the fingerprint instead.

Detects "stale-but-confident" memory entries — facts that were once verified but have silently drifted. Scans memory/*.md for entries past their staleness threshold and proposes re-verification or archival. Runs automatically as part of harvest-loop Step 0-c and on explicit invocation.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

It is the tighter external frame for > what memory-hygiene detects: this skill is the FH-native *detection + archival* pass over the same > failure A-TMA formalizes at the retrieval layer. (Source-verified 2026-07-03; a broader bounded-memory > testbed, arXiv:2607.02255 AgenticSTS, was considered and set aside — it targets context-assembly, not > staleness, so it is not the sister here.) FH is an online-first harness. Its memory entries point to live external resources (GitHub …

How to install
mdr add chrono-meta/forge-harness/memory-hygiene@sha256:79d8b162379d0ba2The line at the top of this page pins the label git:20260811.eede7ad, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
