prp-ts-create

prp-ts-create is a command for Claude Code from mort-lab/excel-mcp. It costs 0 tokens per session (1,282 once invoked), scanned A, original, MIT.

A command for creating a detailed TypeScript PRP, or implementation plan, through codebase research and context gathering.

In plain words
What is it for?
Researching a TypeScript or React project and producing a plan intended to support a one-pass feature implementation.
Why use it?
It gives the coding agent specific files, patterns, requirements, and research so it has less need to guess during implementation.

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-ts-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 4d 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.

Create TypeScript PRP

Feature: $ARGUMENTS

PRP Creation Mission

Create a comprehensive TypeScript PRP that enables one-pass implementation success through systematic research and context curation.

Critical Understanding: The executing AI agent only receives:

  • Start by reading and understanding the prp concepts PRPs/README.md
  • The PRP content you create
  • Its training data knowledge
  • Access to codebase files (but needs guidance on which ones)

Therefore: Your research and context curation directly determines implementation success. Incomplete context = implementation failure.

Research Process

During the research process, create clear tasks and spawn as many agents and subagents as needed using the batch tools. The deeper research we do here the better the PRP will be. we optminize for chance of success and not for speed.

  1. TypeScript/React Codebase Analysis in depth

    • Create clear todos and spawn subagents to search the codebase for similar features/patterns Think hard and plan your approach
    • Identify all the necessary TypeScript files to reference in the PRP
    • Note all existing TypeScript/React conventions to follow
    • Check existing component patterns, hook patterns, and API route patterns
    • Analyze TypeScript interface definitions and type usage patterns
    • Check existing test patterns for React components and TypeScript code validation approach
    • Use the batch tools to spawn subagents to search the codebase for similar features/patterns
  2. TypeScript/React External Research at scale

    • Create clear todos and spawn with instructions subagents to do deep research for similar features/patterns online and include urls to documentation and examples
    • TypeScript documentation (include specific URLs with version compatibility)
    • React/Next.js documentation (include specific URLs for App Router, Server Components, etc.)
    • For critical pieces of documentation add a .md file to PRPs/ai_docs and reference it in the PRP with clear reasoning and instructions
    • Implementation examples (GitHub/StackOverflow/blogs) specific to TypeScript/React/Next.js
    • Best practices and common pitfalls found during research (TypeScript compilation issues, React hydration, Next.js gotchas)
    • Use the batch tools to spawn subagents to search for similar features/patterns online and include urls to documentation and examples

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-ts-create is a command published in the GitHub repository mort-lab/excel-mcp (5 stars, last pushed 27d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,282 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.
