<What this skill does. Use this whenever the user mentions <concrete contexts and trigger phrases>, even if they don't explicitly ask for <skill name>.>.
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 Name> <One-paragraph purpose: what this skill enables the agent to do, and when to reach for it.> ## When to trigger <Restate/expand the trigger contexts. Keep "when to use" primarily in the frontmatter description; this section is for the body reader's orientation.> ## Flow <The high-level steps the agent follows when the skill is consulted. Keep lean — put heavy detail in references and point to them.> 1. Step one 2. Step two 3. ... ## References - `references/<topic>.md` — <what it covers, when to read it> ## Templates - `templates/<artifact>` — <what it is, when to copy it> ## Reflexivity self-check (if this is a meta-skill) <If this skill operates on skills or other meta-objects, note the reflexivity defense here: what external anchor keeps its standard from self-validating. Omit for non-meta skills.>

How to install
mdr add labs21-dev/agents-stack/<kebab-case-slug>@sha256:f5c439388f3001cfThe line at the top of this page pins the label git:20260912.9d47cf0, 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.
