Gate-checked, size-and-intent-tiered PRD authoring. Runs a gate-zero first (is a written doc even needed, or is a 3-line ticket or a prototype enough?), then a Brief, one-pager, or big-tier stack; the big tier branches on intent: a PR/FAQ for validation versus a numbered full PRD for execution. Enforces positive, mandatory non-goals at medium and up, ID'd testable traceable requirements, and ends in a hand-off plus a self-grade. Use for "write a PRD", "draft product requirements", or…
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
# Product PRD Author the *right* product doc for the work (sometimes a 3-line ticket, sometimes a full PRD), never more than the work warrants. This skill writes no application code; it produces the requirements a build (`implement-feature`) then works from. Output lands under `docs/specs/prd/`. `<skill-dir>` below is this skill's directory. ## Input $ARGUMENTS Parse the source (first match wins), then read it: | Pattern | Source | Read via | |---|---|---| | `PROJ-123` | Jira | `jira issue view PROJ-123` | | `#42` / `owner/repo#42` | GitHub issue | `gh issue view 42 --json title,body,labels,comments` | | `!123` / PR URL | GitHub PR | `gh pr view 123 --json title,body,files` | | existing path | file/dir | Read it (dir: README, CLAUDE.md/AGENTS.md, key files) | | `http(s)://` | URL | `WebFetch` | | anything else | plain text | the idea itself | A trailing `--tier brief|one-pager|big` and/or `--intent validation|execution` overrides the assessment. ## Prerequisites & fallback Parallel research and discovery use the `Task` tool with `Explore`/haiku subagents.

How to install
mdr add mgiovani/cc-arsenal/product-prd@sha256:094235e1201fe068The 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.
