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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00024 | $0.00484 |
| Opus 5 | $0.00012 | $0.00242 |
| Sonnet 5 | $0.00005 | $0.00097 |
| Haiku 4.5 | $0.00002 | $0.00048 |
Grade A, and why
prd-writer 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 10d 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.

When to Use
- Starting a new feature or product initiative
- Need to document requirements for the engineering team
- Stakeholders need a detailed project overview
- Before beginning design or development work
- To align cross-functional teams on scope and goals
What This Skill Does
Creates structured, comprehensive PRDs covering problem statement, proposed solution, requirements, success metrics, and implementation details.
Instructions
Help me write a comprehensive PRD for [feature name]. Include:
- Problem Statement
- Current situation
- User pain points
- Business impact
- Proposed Solution
- Overview of the approach
- User stories
- Success metrics
- Requirements
- Functional requirements
- Technical requirements
- Design requirements
- Implementation

- Consider technical constraints upfront
- Add detailed user stories for key flows
- Include acceptance criteria
Example
Input: Building a notification center for SaaS app, target users are power users who miss important updates Output: Full PRD with problem statement, user stories, functional/technical requirements, success metrics (reduce missed notifications by 40%), timeline, and risk assessment

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.
