prp-poc-execute-parallel

prp-poc-execute-parallel is a command for Claude Code from mort-lab/excel-mcp. It costs 0 tokens per session (2,845 once invoked), scanned A, original, MIT.

A command that turns several existing React proof-of-concept plans into working demonstrations at the same time. It coordinates separate interface implementation and user-flow validation for each demo.

In plain words
What is it for?
Use it to implement a group of React POCs from matching PRP directories and validate their interface and user flows.
Why use it?
It helps test multiple concepts in parallel and checks both how they look and whether their main journeys work.

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-poc-execute-parallel 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.

Execute Parallel React POCs

POC Directory: $ARGUMENTS

Usage: /prp-poc-execute-parallel [poc_directory_pattern] Example: /prp-poc-execute-parallel "PRPs/poc-dashboard-*"

Mission: Parallel POC Implementation Success

Transform multiple React POC PRPs into working demonstrations simultaneously through coordinated parallel execution using specialized UI/UX and User Journey agents.

Critical Understanding: Each POC requires specialized execution:

  • UI-focused implementation leveraging @ui-ux-agent expertise
  • User journey validation using @user-journey-agent insights
  • Parallel development without interference between POCs
  • Coordinated validation ensuring all POCs demonstrate successfully

Parallel Execution Strategy

Agent Orchestration Pattern

For N POCs discovered, create N execution pairs:

  • N UI-UX Implementation Agents: Each building the specific UI approach
  • N User Journey Validation Agents: Each ensuring journey flows work correctly

Execution Agent Assignment:

POC 1: @ui-ux-agent (Build minimal/clean interface) + @user-journey-agent (Validate power user flows)
POC 2: @ui-ux-agent (Build polished/professional interface) + @user-journey-agent (Validate casual user flows)
POC 3: @ui-ux-agent (Build experimental/modern interface) + @user-journey-agent (Validate admin user flows)
POC 4: @ui-ux-agent (Build dashboard/data-heavy interface) + @user-journey-agent (Validate mobile-first flows)
POC 5: @ui-ux-agent (Build component-library interface) + @user-journey-agent (Validate accessibility flows)

Pre-Execution Setup

Step 1: Environment Preparation

  1. Create Fresh React Project

    npx create-react-app react-poc-demos --template typescript
    cd react-poc-demos
    npm install react-router-dom @faker-js/faker msw
    npm install -D @types/react-router-dom
    
  2. Discover POC PRPs

    • Scan for POC PRP files matching the pattern
    • Extract POC specifications and requirements
    • Plan directory structure and routing

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-poc-execute-parallel 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 2,845 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.
