requirement-study

requirement-study is a skill for Claude Code, Codex from gyanranjan/polyagent-skills. It costs 85 tokens per session (1,839 once invoked), scanned A, original, MIT.

A requirements-analysis guide that turns conversations, documents, rough notes, feature requests, or existing specifications into structured software requirements. It can also produce a PRD, a Product Requirements Document describing what a product should include.

In plain words
What is it for?
Use it to study a feature request, extract requirements from a document, write a PRD, or check whether existing requirements are complete.
Why use it?
It helps turn incomplete or informal ideas into a clear list of what needs to be built. It also helps find missing or unclear requirements before development starts.

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

requirement-study 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 8d 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.

Requirement Study

Purpose

Transform any input (rough notes, conversation transcripts, feature requests, existing documents) into structured, actionable software requirements. Produces a requirements document that any development team can use to plan and build.

When to Use

  • User asks to "study requirements" or "analyze requirements"
  • User provides rough notes/ideas and wants them formalized
  • User asks for a PRD (Product Requirements Document)
  • User wants to extract requirements from an existing document
  • User asks "what do we need to build for X?"
  • User wants to validate completeness of existing requirements

When NOT to Use

  • User wants implementation details (use implementation-sketch instead)
  • User wants a presentation (use deck-creator instead)
  • User is asking about deployment/ops (use remote-ops instead)

Inputs

Required:

  • Source material — the raw input to derive requirements from (document, notes, conversation, or verbal description)

Optional:

  • Target audience — who will read this requirements doc?
  • Scope constraints — any known boundaries or limitations
  • Existing requirements — if this is a refinement of existing work
  • Template preference — if the user's org has a standard format

Process

Step 1: Preflight Tooling Check

Run a non-blocking Mermaid check for future diagram generation:

if command -v mmdc >/dev/null 2>&1; then
  mmdc --version
else
  echo "mmdc not installed; continue with text/Markdown diagrams and add TODO entry"
fi

If mmdc is missing, add a task to agent.todo.md under Next or Blocked.

Interaction Protocol (Mandatory)

For all substantive responses while running this skill:

  • Include Stage: Gx <name> and Next: <immediate next step>
  • At each gate transition, ask 2-4 decision-oriented questions before advancing
  • Challenge weak assumptions and propose stronger alternatives with rationale

Step 2: Understand the Domain

Read the source material completely. Identify:

  • The domain/industry context
  • Key stakeholders mentioned
  • The problem being solved
  • Any existing system or process being replaced/enhanced

Changes

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.
