Generate a Product Requirements Prompt for engineering handoff. Needs an approved PRD. Sensors, link validation, and eval gates.
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 a PRP. Follow guides/pipeline.md for retry, approval, and publish.
Source PRD: if user passes a path, use it. Else pick the most recent in .claude/runtime/outputs/pm/prd/. None found, abort. Tell user to run /product-manager:prd first. hooks/pre-prp-check.sh blocks if the PRD lacks the approved marker.
Compute feature_id from the source PRD filename (basename without .md). Save the PRP to .claude/runtime/outputs/pm/prp/{feature_id}.md so it matches.
Before generating, write the phase start marker:
```
.claude/runtime/outputs/pm/.markers/{feature_id}.prp-generate.start
```
Content: `{"timestamp": "<ISO-8601 UTC now>", "session_id": ""}`
Read:
- the source PRD
- guides/prp-guidelines.md
- guides/writing-style.md
- guides/templates/prp.md
- guides/pipeline.md
- guides/examples/good-prp-example.md
- .claude/shared/context-strategy.md, pick the right tier when exploring target repos
Explore target repos. Ask user for repo paths if not provided. Run `.claude/scripts/context-tools.sh {repo}` once, then per `context-strategy.md` § `/product-manager:prp`:

How to install
mdr add pierry/harness-kit/prp@sha256:7256bf7e429dea2dThe line at the top of this page pins the label git:20261005.0119af1, 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.
