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 | $0.00024 | $0.01187 |
| Opus 5 | $0.00012 | $0.00593 |
| Sonnet 5 | $0.00005 | $0.00237 |
| Haiku 4.5 | $0.00002 | $0.00119 |
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 8d 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 — 193 lines — stays where its author put it; the contents beside it link to each section on GitHub.
User Stories Skill
This skill provides guidance for writing well-formed user stories with clear acceptance criteria.
User Story Format
As a [type of user],
I want [goal/desire],
So that [benefit/value].
Examples
Good:
As a registered user,
I want to reset my password via email,
So that I can regain access to my account if I forget my password.
Bad:
Add password reset feature.
The good example captures WHO needs it, WHAT they need, and WHY.
INVEST Criteria
Good user stories are:
| Criteria | Description |
|---|---|
| Independent | Can be developed separately from other stories |
| Negotiable | Details can be discussed and refined |
| Valuable | Delivers clear value to the user |
| Estimable | Can be sized (fits in a single PR) |
| Small | Implementable in one PR, not weeks of work |
| Testable | Has clear acceptance criteria to verify |
Checking Your Stories
- Independent: Does this require other stories to be done first? If so, document the dependency.
- Negotiable: Is there flexibility in HOW this is implemented?
- Valuable: Can you explain the user benefit?
- Estimable: Is it clear enough to implement?
- Small: Could this be done in 1-3 days? If not, break it down.
- Testable: Can you write acceptance criteria?
Acceptance Criteria
Acceptance criteria define WHEN a story is complete. They should be:
- Specific: Clear, unambiguous conditions
- Measurable: Can be verified as pass/fail
- Complete: Cover the happy path AND edge cases
Format
Use checkbox format for easy verification:
## Acceptance Criteria
- [ ] User can request password reset with their email
- [ ] Reset link is sent to registered email only
- [ ] Reset link expires after 1 hour
- [ ] User sees error message for unregistered email
- [ ] User can set new password via reset link
- [ ] Old password no longer works after reset
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 shwilliamson/automatasaurus (5 stars, last pushed 6mo ago), licensed MIT. It adds 24 tokens to every session and 1,187 once invoked, about $0.0001 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.
