Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00040 | $0.03081 |
| Opus 5 | $0.00020 | $0.01541 |
| Sonnet 5 | $0.00008 | $0.00616 |
| Haiku 4.5 | $0.00004 | $0.00308 |
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.mdfor precedence, invocation, delegation, and handoffs. Applyinstructions/workflow.instructions.mdfor 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-planningorprd-workflowneeds 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-recordskill instead). - Architecture/design implementation plans — use
feature-planningorprd-workflow; this skill stops at backlog/story breakdown.
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.

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.
