ensemble-create-prd

ensemble-create-prd is a skill for Claude Code, Codex from FortiumPartners/ensemble. It costs 29 tokens per session (3,168 once invoked), scanned A, original, MIT.

A guided workflow for creating a Product Requirements Document, which explains what a product must do. It gathers requirements through questions, adjusts the document to project size, and reviews it for implementation readiness.

In plain words
What is it for?
Use it to interview stakeholders, write structured product requirements, define acceptance checks, and review the document before coding.
Why use it?
It helps uncover missing expectations and unclear requirements before development work is handed off.

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

ensemble-create-prd 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 6d 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.

Ensemble Command: /ensemble:create-prd

This Codex skill mirrors the Ensemble slash command /ensemble:create-prd. Follow the workflow below, adapt to the current repository, and keep outputs structured.

Create a comprehensive Product Requirements Document (PRD) through structured elicitation, contextual research, and adversarial self-review. Adapts depth to project scale (solo dev through enterprise). Uses clarifying interviews and creative elicitation techniques to surface hidden requirements before writing. Every PRD passes an Implementation Readiness Gate before being saved to ensure handoff quality.

Workflow

Phase 1: Structured Elicitation

1. Scale Detection Determine project complexity to calibrate PRD depth

  • Ask the user: 'Is this a solo/side project, small team (2-5), or enterprise/multi-team effort?'
  • If user provided a product description as arguments, read it first, then ask -- don't make them repeat themselves
  • Set depth level: LIGHT (solo -- 5-10 requirements, minimal ceremony), STANDARD (small team -- 10-25 requirements, full ACs), DEEP (enterprise -- 25+ requirements, risk analysis, compliance section)
  • Announce the chosen depth level so the user can override if needed

2. Problem Space Interview Gather core product context through a one-question-at-a-time interview

  • INTERVIEW PROTOCOL: Ask exactly ONE question, wait for the user's full answer, then ask the next. Never batch questions.
  • Determine which of these questions are NOT already answered by the product description provided as arguments, then ask only the unanswered ones in order:
  • Q1: 'What problem does this solve, and who feels the pain today?'
  • Q2: 'Who are the primary users? (describe by role, not by name)'
  • Q3: 'What does success look like -- ideally with specific metrics?'
  • Q4: 'What constraints apply? (budget, timeline, tech stack, compliance, etc.)'
  • Q5: 'What existing solutions have been tried or considered, and why weren't they enough?'
  • After each answer: acknowledge it briefly (1 sentence), then ask the next question
  • After the final answer: summarize what you heard in 3-4 sentences and ask the user to confirm before continuing

ensemble-create-prd is a skill published in the GitHub repository FortiumPartners/ensemble (11 stars, last pushed 1mo ago), licensed MIT. It adds 29 tokens to every session and 3,168 once invoked, about $0.0001 per session on Opus 5. 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 2026-08-30.
