What it does

Prd Authoring is an agent skill from bobmatnyc/claude-mpm. Standard for authoring product PRDs in docs/prd/: state the problem, users, requirements, and success; assign PRD-{AREA}-{NN} IDs; link down to specs.

Its SKILL.md is about 1.7k tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including reference files (for example `references/ia-and-categories.md`, `references/prd-lifecycle.md` and `references/prd-research-practices.md`).

It sits in Product & Project Management, covering PRD writing. The repository describes itself as: Claude Multi-Agent Project Manager — multi-channel orchestration, GitHub-first SDK mode, and plugin system for Claude.

When your agent uses it

  • Tasks that involve PRD writing

Example prompts

  • “/prd-authoring”

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. Read the grammar. docs/prd/README.md §3 defines
  2. Pick or create the area file. One product area = one file. See
  3. Apply the template. Copy docs/prd/TEMPLATE.md;
  4. Ground it in research. Non-obvious requirements cite product/user/market research. See
  5. Map requirements to specs. Fill the Linked Specs table; engineering authors the specs and
  6. Manage the lifecycle. Draft → Review → Approved → In-development → Shipped → Superseded.

What it can do on your machine

Read from SKILL.md and the folder at commit 25203d3. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Prd Authoring loads about 1.7k tokens when it runs, and up to ~8.6k if it reads all its reference files. Until then it costs about 41 tokens; SKILL.md has 605 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~41
When it runs · the whole SKILL.md, loaded when a task matches
~1.7k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~8.6k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 605 words (~1,735 tokens).

“This skill is the agent-facing entry point to the Product PRD Standard: how to write Product Requirements Documents in docs/prd/. A PRD answers what problem, for which users, what requirements, and what success looks like — and is owned by…”
