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
# Skill inventory
Make the `skill-inventory` utility available to this agent and hand off to its own documentation. This skill and the utility share a name: the utility is an offline Python tool that ships as an armory utility package, which the Skills CLI and the Claude Code plugin marketplace do not install. This skill is the installable entry point that bridges that gap, without copying the utility's code or measurement rules.
## When to use
|Use when|Use instead|
|---|---|
|Auditing installed skill descriptions, observed reads or unused managed skills|—|
|The utility is not installed, or you do not know where it is|—|
|Diagnosing what fills the current context window|usage-audit|
|Searching or installing armory packages|skill-library|
|Static conformance report or authored package audit; live effectiveness `NOT_MEASURED`|package-evaluator|
Triggers group into inventory audits ("audit my skill inventory", "find unused skills", "which skills were read?"), cost questions ("how much do skill descriptions cost?") and setup ("set up skill-inventory", "run the skill inventory utility").

How to install
mdr add mathews-tom/armory/skill-inventory@sha256:57ac93c8df9dcea2The line at the top of this page pins the label v1.0.1, 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.
