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 | $0.00080 | $0.01231 |
| Opus 5 | $0.00040 | $0.00616 |
| Sonnet 5 | $0.00016 | $0.00246 |
| Haiku 4.5 | $0.00008 | $0.00123 |
Grade A, and why
sprint-planning 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.
How it starts
The opening of the file, as written. The whole thing — 172 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Sprint Planning
User Story Writing
Format
As a [type of user],
I want [goal or action],
So that [benefit or value].
Acceptance Criteria Format (Gherkin)
Given [initial context or precondition],
When [action or event occurs],
Then [expected outcome].
User Story Example
I want to reset my password via email, So that I can regain access to my account if I forget my credentials.
Acceptance Criteria: Given I am on the login page, When I click "Forgot Password" and enter my email, Then I should receive a password reset email within 2 minutes.
Given I click the reset link in the email, When I enter a new valid password, Then my password should be updated and I should be logged in.
### Story Quality Checklist (INVEST)
- **I**ndependent — can be developed without depending on other stories
- **N**egotiable — details can be discussed
- **V**aluable — delivers value to a user or stakeholder
- **E**stimable — team can estimate it
- **S**mall — completable in one sprint
- **T**estable — acceptance criteria are verifiable

## Story Point Estimation
### Scale Reference
| Points | Size | Description |
|---|---|---|
| 1 | XS | Trivial change, well-understood, < 2 hours |
| 3 | S | Small, clear scope, half a day |
| 5 | M | Medium complexity, 1–2 days |
| 8 | L | Complex, cross-cutting, 3–4 days |
| 13 | XL | Very complex or uncertain, needs breakdown |
### Estimation Rules
- If a story is 13 points, break it down into smaller stories
- Points represent **complexity + uncertainty**, not just time
- Estimate as a team — avoid anchoring bias (don't share estimates until everyone reveals simultaneously)
- Use historical velocity to validate sprint capacity
---
## Sprint Goal Formula (FOCUS Model)
A good sprint goal is:
- **F**un — memorable and motivating title
- **O**utcome-oriented — what value is delivered, not what tasks are done
- **C**ollaborative — agreed upon by the whole team
- **U**ltimate — answers "why are we doing this sprint?"
- **S**ingular — one clear goal, not a list
### Sprint Goal Example
By end of sprint, users can sign up, log in, and access their dashboard —
giving us a working auth system to build all future features on.
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.

sprint-planning is a skill published in the GitHub repository jamestorrevillas/dev-skills (3 stars, last pushed 5mo ago), licensed MIT. It adds 80 tokens to every session and 1,231 once invoked, about $0.0004 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.
