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
# AGENTS.md This file provides guidance to coding agents (e.g., Posit Assistant, Claude Code, Codex, Cursor) when working with code in this repository. ## What This Repository Is A collection of Agent Skills published by Posit PBC. Skills are structured markdown files, following the [Agent Skills specification](https://agentskills.io), that teach coding agents specialized workflows (e.g., Shiny app development, R package testing, GitHub PR workflows). There is no application code to build, compile, or deploy — the primary artifacts are Markdown files consumed directly by coding agents that support the Agent Skills format. ## Utility Scripts Two runnable utilities live at the repo root. `count-skill-tokens.py` reports line and token counts for a skill: ```bash # Requires uv ./count-skill-tokens.py shiny/shiny-bslib # or uv run count-skill-tokens.py r-lib/r-cli ``` Warns when `SKILL.md` exceeds **5,000 tokens / 500 lines**, or when the skill `description` frontmatter exceeds **100 tokens**. `find-stale-references.py` finds references to old skill names after a rename, so stale mentions don't linger in the repo or in users' projects: ```bash …

How to install
mdr add posit-dev/skills/AGENTS.md@sha256:c2250a6b5afc1e16The line at the top of this page pins the label git:20261007.4d770f9, 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.
