requirement-breakdown

requirement-breakdown is a skill for Claude Code, Codex from NickPolyder/NP.CoPilot.Config. It costs 40 tokens per session (3,081 once invoked), scanned A, original, MIT.

A planning process that breaks a broad software requirement into epics, user stories, acceptance criteria, dependencies, and assigned specialist work.

In plain words
What is it for?
It helps clarify ambiguous requirements, write Given/When/Then acceptance criteria, assign the right agents, and identify the order of dependent work.
Why use it?
It turns vague requests into smaller pieces that can be understood, tested, and scheduled without starting 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

requirement-breakdown 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.

How it starts

The opening of the file, as written. The whole thing — 378 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Purpose

Intent (anchor): Convert one high-level requirement into an epic, user stories, acceptance criteria, agent assignments, and dependencies. Always: ask clarifying questions before decomposing ambiguous work; use INVEST and Given/When/Then; surface cross-cutting concerns. Never: make architectural decisions or start implementation.

Shared policy: Follow instructions/coordination.instructions.md for precedence, invocation, delegation, and handoffs. Apply instructions/workflow.instructions.md for proportional work and verification.

You are breaking down a high-level requirement into actionable development work.

This skill is a backlog/story breakdown delegate for feature-planning and prd-workflow when deeper story detail is needed. It does not create architecture, design, or implementation plans.

Your goals are to:

  • Transform vague or broad requirements into specific, implementable user stories.
  • Write testable acceptance criteria for every story.
  • Assign stories to the appropriate specialist agents based on the work involved.
  • Identify dependencies between stories to determine implementation order.
  • Ensure nothing is missed — including cross-cutting concerns like security, accessibility, and performance.

When to use this skill

Use this skill whenever:

  • The user provides a high-level feature request or requirement.
  • The user asks to "break down", "plan out", or "scope" a feature.
  • A product requirement needs to be translated into development tasks.
  • You need to create a backlog of stories for a feature.
  • feature-planning or prd-workflow needs a delegated story-level breakdown.

Do not use this skill for:

  • Bug reports (use the bug report template directly).
  • Simple tasks that don't need decomposition (e.g., "add a button").
  • Architecture decisions (use the architecture-decision-record skill instead).
  • Architecture/design implementation plans — use feature-planning or prd-workflow; this skill stops at backlog/story breakdown.

requirement-breakdown is a skill published in the GitHub repository NickPolyder/NP.CoPilot.Config (2 stars, last pushed 11d ago), licensed MIT. It adds 40 tokens to every session and 3,081 once invoked, about $0.0002 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 2026-08-31.
