Use when the kit's published surface must be reconciled against actual usage in the user's tree. Trigger on "stale-lore", "retira capacidades", "capacidades sin ejercicio", "purge unused skills", or after a major refactoring that renames or replaces published capabilities. Not yours: operating a project's criteria body belongs to transmute-lore; saving one lesson belongs to save-to-lore.

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.

What the file says

# stale-lore — Retiro declarativo de capacidades sin ejercicio

> Invoke with the Skill tool as `stale-lore`, or with the phrases «retira capacidades» / «capacidades sin ejercicio» when the published kit surface must be reconciled against actual usage.

The kit announces capabilities — eight skills, contracts, a `<!-- lore:always-on -->` block — and
those promises accumulate. Some get exercised daily. Others were written for a problem that no
longer exists, or were superseded by a better mechanism. A kit that promises everything and uses
nothing is not a kit: it is a catalog nobody verified.

This skill reconciles promise against evidence. It derives the list of central capabilities from what
the kit publishes, searches the user's tree for proof of exercise, marks each receipt with its
`ejercido` state, and withdraws the ones that crossed the stale threshold — with a declarative
trace so the withdrawal itself is auditable.

> **The withdrawal is declarative, not surgical.** It writes a changelog entry and marks the
> receipt. It does not delete the skill from the kit, does not edit the user's `lore/`, and does not

How to install

The exact contents, by fingerprint

mdr add andresanemic/lore-plugin/stale-lore@sha256:af56a0622d6f8377

The line at the top of this page pins the label git:20261007.2784428, 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.
