[Adam''s Skills] Check whether the installed copy of this skills collection is behind its remote, and offer to update it. Runs a script that resolves the clone the skills are linked from, respects a once-a-day rate limit and a remembered refusal, and reports one of: up to date, N commits behind, unsafe to touch, or offline. Only "behind" is ever mentioned to the user; everything else is silent. On a yes it pulls and re-links, changing nothing about which skills are installed. Use when the user…
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
# check-skill-updates Say nothing unless there is something to say. This skill exists to mention a waiting update **once**, at a moment when the user is not busy — and to be invisible the rest of the time. ## Run it ``` node <repo>/tools/freshness/check.mjs ``` `<repo>` is the clone the skills are linked from. Resolve it from **this file's real path**, not from the working directory: `~/.claude/skills/check-skill-updates` is a link, so its target's `../../tools/freshness/check.mjs` is the script. The working directory is whatever the user happens to be editing, which is usually a different repo entirely. The script prints one line of JSON and nothing else. Flags: `--force` (the user asked directly, ignore the rate limit), `--update` (pull and re-link), `--decline` (remember this was turned down). ## What each verdict means | Verdict | What you say | |---|---| | `fresh` | Nothing. Silence is the correct output. | | `too-soon` | Nothing. Already checked within the day. | | `offline` | Nothing. A failed fetch is not the user's problem to hear about. | | `not-installed` | Nothing, unless the user asked directly — then say the clone could not be found. | …

How to install
mdr add adamlinscott/claude-skills/check-skill-updates@sha256:6a4d59fed212e632The line at the top of this page pins the label git:20261026.c0a4905, 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.
