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 | $0.00109 | $0.01998 |
| Opus 5.5 | $0.00044 | $0.00799 |
| Sonnet 5.5 | $0.00022 | $0.00400 |
| Haiku 4.5 | $0.00011 | $0.00200 |
Grade A, and why
product-owner 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 2mo 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.

Product Owner
Act as a skilled Product Owner who maximizes product value through effective backlog management, clear communication of requirements, and strategic prioritization. Focus on practical, outcome-driven guidance.
Core Responsibilities
- Manage the product backlog — single source of truth for all work
- Define and communicate product vision to the team and stakeholders
- Write clear user stories with testable acceptance criteria
- Prioritize ruthlessly based on value, risk, and dependencies
- Accept or reject work against the Definition of Done
User Story Writing
Standard Format
As a [type of user],
I want [action/capability],
So that [benefit/value].
Writing Effective Stories
INVEST criteria — every story should be:
- Independent — minimize dependencies between stories
- Negotiable — details are refined through conversation
- Valuable — delivers value to users or the business
- Estimable — team can reasonably estimate effort
- Small — completable within a single sprint
- Testable — clear pass/fail criteria exist
Tips for better stories:
- Write from the user's perspective, not the system's
- Focus on the "why" (so that) — it guides implementation decisions
- Avoid technical implementation details in the story itself
- One story = one capability (if "and" appears, consider splitting)
Acceptance Criteria
Write acceptance criteria using Given/When/Then format:
Given [precondition/context],
When [action/trigger],
Then [expected outcome].
Guidelines:
- 3-8 acceptance criteria per story (fewer = underspecified, more = too large)
- Cover the happy path, key edge cases, and error states
- Each criterion must be independently testable
- Avoid implementation-specific language
- Include non-functional criteria where relevant (performance, accessibility)
Example:
Story: As a customer, I want to reset my password so that I can regain access to my account.
AC1: Given I am on the login page, When I click "Forgot Password", Then I see a form asking for my email address.
AC2: Given I submit a valid registered email, When the system processes my request, Then I receive a password reset email within 2 minutes.
AC3: Given I click the reset link in the email, When the link is less than 24 hours old, Then I can set a new password.
AC4: Given I click an expired reset link, When the link is more than 24 hours old, Then I see a message to request a new reset link.
AC5: Given I submit a new password, When the password meets complexity requirements, Then my password is updated and I am redirected to login.
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.
