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 | $0.00051 | $0.00655 |
| Opus 5 | $0.00026 | $0.00328 |
| Sonnet 5 | $0.00010 | $0.00131 |
| Haiku 4.5 | $0.00005 | $0.00065 |
Grade A, and why
user-stories 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 12d 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
100% identical to user-stories — 0 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 — 75 lines — stays where its author put it; the contents beside it link to each section on GitHub.
User Stories
Create user stories following the 3 C's (Card, Conversation, Confirmation) and INVEST criteria. Generates stories with descriptions, design links, and acceptance criteria.
Use when: Writing user stories, breaking down features into stories, creating backlog items, or defining acceptance criteria.
Arguments:
$PRODUCT: The product or system name$FEATURE: The new feature to break into stories$DESIGN: Link to design files (Figma, Miro, etc.)$ASSUMPTIONS: Key assumptions or context
Step-by-Step Process
- Analyze the feature based on provided design and context
- Identify user roles and distinct user journeys
- Apply 3 C's framework:
- Card: Simple title and one-liner
- Conversation: Detailed discussion of intent
- Confirmation: Clear acceptance criteria
- Respect INVEST criteria: Independent, Negotiable, Valuable, Estimable, Small, Testable
- Use plain language a primary school graduate can understand
- Link to design files for visual reference
- Output user stories in structured format
Story Template
Title: [Feature name]
Description: As a [user role], I want to [action], so that [benefit].
Design: [Link to design files]
Acceptance Criteria:
- [Clear, testable criterion]
- [Observable behavior]
- [System validates correctly]
- [Edge case handling]
- [Performance or accessibility consideration]
- [Integration point]
Example User Story
Title: Recently Viewed Section
Description: As an Online Shopper, I want to see a 'Recently viewed' section on the product page to easily revisit items I considered.
Design: [Figma link]
Acceptance Criteria:
- The 'Recently viewed' section is displayed at the bottom of the product page for every user who has previously viewed at least 1 product.
- It is not displayed for users visiting the first product page of their session.
- The current product itself is excluded from the displayed items.
- The section showcases product cards or thumbnails with images, titles, and prices.
- Each product card indicates when it was viewed (e.g., 'Viewed 5 minutes ago').
- Clicking on a product card leads the user to the corresponding product page.
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.

user-stories is a skill published in the GitHub repository unixcrh/phuryn-pm-skills (2 stars, last pushed 6mo ago), licensed MIT. It adds 51 tokens to every session and 655 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to user-stories, differing in 0 lines, and is treated as a copy.
