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 | $0.00054 | $0.02783 |
| Opus 5 | $0.00027 | $0.01392 |
| Sonnet 5 | $0.00011 | $0.00557 |
| Haiku 4.5 | $0.00005 | $0.00278 |
Grade A, and why
cy-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 2d 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.
This is a copy
88% identical to cy-create-prd — 67 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 186 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Create PRD
Create a business-focused Product Requirements Document through structured brainstorming.
Asking Questions
When this skill instructs you to ask the user a question, you MUST use your runtime's dedicated interactive question tool — the tool or function that presents a question to the user and pauses execution until the user responds. Do not output questions as plain assistant text and continue generating; always use the mechanism that blocks until the user has answered.
If your runtime does not provide such a tool, present the question as your complete message and stop generating. Do not answer your own question or proceed without user input.
Anti-Pattern: "This Feature Is Too Simple For Full Brainstorming"
Every PRD goes through the full brainstorming process. A single button, a minor workflow tweak, a configuration option — all of them. "Simple" features are where unexamined business assumptions cause the most rework. The brainstorming can be brief for genuinely simple features, but you MUST ask clarifying questions and get approval on the product approach before writing the artifact.
Anti-Pattern: End-Of-Flow Bureaucracy
Once the user has answered the clarifying questions and approved an approach, do not force them through a second approval loop for Overview, Goals, User Stories, or any other final document section. Synthesize the approved direction into the PRD directly. The user can review and request edits in the generated file afterward.

What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
- 2d ago First seen · 186 lines · 54 tokens per session scan A 457dc26b97ef
cy-create-prd is a skill published in the GitHub repository compozy/skeeper (85 stars, last pushed 3mo ago), licensed MIT. It adds 54 tokens to every session and 2,783 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. It is 88% identical to cy-create-prd, differing in 67 lines, and is treated as a copy.
