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
# Generate/Update PR Description
Generates or updates a PR description with incremental information, auto-updates the title, and links the Linear ticket — fully automated, no interactive prompts.
**Paths.** Commands below name files inside this skill's own directory as `${CLAUDE_SKILL_DIR}/…`. Claude Code fills that in. On any other harness, set CLAUDE_SKILL_DIR to the absolute directory that contains this SKILL.md before running them. If you cannot, stop and report `skill_dir_unresolved`.
## Prerequisites
```bash
# Thoughts must exist for this skill's documents. CTL-2306: the full host setup check (daemon,
# registry, house rules) belongs to the setup-catalyst skill, not to a skill that must run anywhere.
[[ -e thoughts/shared ]] || echo "⚠️ thoughts/shared is missing in $(pwd) — run \`humanlayer thoughts init\` or the setup-catalyst skill; if the prompt names an output path, write there" >&2
```
## No Claude attribution
Never write "Generated with Claude Code", "Co-Authored-By: Claude", or any AI-assistance reference into a PR title or body. Descriptions are professional and attributed to the human author.

How to install
mdr add coalesce-labs/catalyst/describe-pr@sha256:05cbf8b837f6189fThe line at the top of this page pins the label v2.0.0, 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.
