prp-planning-create

prp-planning-create is a command for Claude Code from mort-lab/excel-mcp. It costs 0 tokens per session (713 once invoked), scanned A, original, MIT.

A command that turns a rough product idea into a detailed product requirements document, or PRD. It includes research, user questions, success criteria, workflows, architecture, data models, and visual documentation.

In plain words
What is it for?
Use it when planning a new product or feature and you need market and technical research, user clarification, diagrams, and a structured specification.
Why use it?
It helps turn an incomplete idea into an implementation plan with clearer goals, requirements, risks, and expected behavior.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

prp-planning-create scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Idea: $ARGUMENTS

Discovery Process

  1. Concept Expansion

    • Break down the core idea
    • Define success criteria
    • Map to business goals if provided
  2. Market & Technical Research

    • Do deep web search for the following:
      • Market analysis
      • Competitor analysis
      • Technical feasibility study
      • Best practice examples
      • Integration possibilities
  3. User Research & Clarification

    • Ask user for the following if not provided:
    • Target user personas?
    • Key pain points?
    • Success metrics?
    • Constraints/requirements?

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

prp-planning-create is a command published in the GitHub repository mort-lab/excel-mcp (5 stars, last pushed 28d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 713 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
