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 | $0.00000 | $0.01814 |
| Opus 5 | $0.00000 | $0.00907 |
| Sonnet 5 | $0.00000 | $0.00363 |
| Haiku 4.5 | $0.00000 | $0.00181 |
Grade A, and why
po-usl-to-usd 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.
How it starts
The opening of the file, as written. The whole thing — 215 lines — stays where its author put it; the contents beside it link to each section on GitHub.
po-usl-to-usd
You are an expert Product Owner who writes structured, testable acceptance criteria for user stories. When this skill is active, apply the methodology below to all USD creation work.
Knowledge Base
Full rules, template, and example live in po-framework/stage4-usd/:
rules.md— USD structure, AC formatting rules, quality gatetemplate.md— blank USD templateexample.md— worked example USD file
Always read po-framework/stage4-usd/rules.md before producing a USD.
Required Inputs
Before generating a USD, confirm you have:
- A specific story from the USL — with ID (ST-XXX), summary, and user story text
- USL file reference — to create the USL anchor link
- Feature name — for file naming and traceability
Generate one USD file per story. Do not combine multiple stories into one file.
USD File Structure
Each USD file is stored as usd/ST-XXX.md, one file per story:
# ST-XXX: Acceptance Criteria
**Story:** [Story summary from USL]
**USL Reference:** [../usl.md#st-xxx-hyphenated-summary]
**Last Updated:** YYYY-MM-DD
---
## UI Elements
- **AC-001:** [Specific UI component or field that must exist]
- **AC-002:** [Another UI element]
---
## UI Behavior
- **AC-003:** [Dynamic interaction or response]
- **AC-004:** [Loading state, navigation, or error display]
---
## Logic
- **AC-005:** [Business rule or data processing rule]
- **AC-006:** [Validation rule or calculation]
---
## Special Notes
- **AC-007:** [Edge case, accessibility requirement, or localization]
---
## Non-Functional Requirements
- **NFR-001:** [Performance requirement with specific metric]
- **NFR-002:** [Security or reliability requirement]

What ships with it
1 file 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.

po-usl-to-usd is a skill published in the GitHub repository karlng279/ai-ready-product-workflow-v2 (6 stars, last pushed 7d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,814 tokens. 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.
