  • Works in 7 steps: Gather Product Context → Write Problem Statement → Define User Personas → …

What it does

Memstack Product Prd Writer is an agent skill from cwinvestments/memstack. Use this skill when the user says 'PRD', 'product requirements', 'requirements document', or needs a complete engineering-ready PRD with problem statement, personas, MoSCoW features, and success metrics. Do NOT use for single feature specs or user story backlogs.

Its SKILL.md is about 2.6k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Product & Project Management, covering PRD writing. The repository describes itself as: Structured skill framework for Claude Code. 130 skills, persistent memory, TokenStack compression, localhost dashboard with 3-agent runner, real-time streaming, MCP tools.

When your agent uses it

  • The user says PRD
  • Product requirements
  • Requirements document
  • Needs a complete engineering-ready PRD with problem statement

Example prompts

  • “product requirements”
  • “requirements document”
  • “/memstack-product-prd-writer”

Workflow steps

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

  1. Gather Product Context
  2. Write Problem Statement
  3. Define User Personas
  4. List Requirements (MoSCoW)
  5. Define User Flows
  6. Define Success Metrics
  7. Outline Timeline & Dependencies

What it can do on your machine

Read from SKILL.md and the folder at commit 00370ce. 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 (its code samples are markdown).

    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

Memstack Product Prd Writer loads about 2.6k tokens when it runs. Until then it costs about 73 tokens; SKILL.md has 831 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~73
When it runs · the whole SKILL.md, loaded when a task matches
~2.6k

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 (Proprietary) doesn't allow us to republish the file, so here is its outline and opening line. It has 831 words (~2,564 tokens).

“Generates a complete engineering-ready PRD with problem statement, user personas, functional and non-functional requirements, MoSCoW prioritization, success metrics, and implementation timeline.”
