What it does

Prd Mastery is an agent skill from coco-research/coco. Use when the user asks for a PRD, requirements doc, or product spec grounded in the existing repo, or wants a token-efficient PRD folder. Runs repo reconnaissance, expert questioning, then writes the PRD.

Its SKILL.md is about 4.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 9 other files (for example `create_prd.js`, `examples/folder-structure.md` and `examples/prd-example.md`).

It sits in Product & Project Management, covering PRD writing. The repository describes itself as: CoCo Super Intelligence is the orchestration layer that turns Claude Code, Cursor, or Codex into an engineering department: a routed advisory board, 226 skills, 386 commands…

When your agent uses it

  • The user asks for a PRD
  • Requirements doc
  • Product spec grounded in the existing repo
  • Wants a token-efficient PRD folder

Example prompts

  • “/prd-mastery”

Requirements

  • Node.js

Workflow steps

11 steps, taken from the step headings in SKILL.md.

  1. Initial Reconnaissance
  2. Identify Project Stage and Tech Context
  3. Guide the User (Expert-Driven Approach)
  4. Apply Best Practices and Organize Output
  5. Always Start with Context
  6. Focus on Outcomes, Not Outputs
  7. Validate Assumptions Early
  8. Keep PRDs Living Documents
  9. Optimize for AI and Humans
  10. Maintain Traceability
  11. Use Templates Consistently

What it can do on your machine

Read from SKILL.md and the folder at commit 2ddb559. 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

    Ships script files (JavaScript), which the agent can run.

    Shell commands in SKILL.md call:

    • node
    • pnpm

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

  • Network

    No URLs in SKILL.md. Its commands use pnpm, which can reach the network depending on how they are called.

    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 Mastery loads about 4.1k tokens when it runs. Until then it costs about 54 tokens; SKILL.md has 1,429 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~54
When it runs · the whole SKILL.md, loaded when a task matches
~4.1k

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 1,429 words (~4,143 tokens).
