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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00000 | $0.02845 |
| Opus 5.5 | $0.00000 | $0.01138 |
| Sonnet 5.5 | $0.00000 | $0.00569 |
| Haiku 4.5 | $0.00000 | $0.00284 |
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 2mo 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.
How it starts
The opening of the file, as written. The whole thing — 326 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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
-
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 -
Discover POC PRPs
- Scan for POC PRP files matching the pattern
- Extract POC specifications and requirements
- Plan directory structure and routing
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-poc-execute-parallel is a command published in the GitHub repository mort-lab/excel-mcp (5 stars, last pushed 2mo 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.
