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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00070 | $0.00668 |
| Opus 5 | $0.00035 | $0.00334 |
| Sonnet 5 | $0.00014 | $0.00134 |
| Haiku 4.5 | $0.00007 | $0.00067 |
Grade A, and why
sprint-brief 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 — 62 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Sprint Brief Skill
Produce a clear, scannable sprint brief that every team member — engineer, designer, PM — can read in under three minutes and understand exactly what we're doing and why.
Required Inputs
Ask the user for these if not provided:
- Sprint name and number
- Sprint goal (1-2 sentences — flag if too vague)
- Ticket list with owners (or a description of the work)
- Known dependencies or blockers
- Carry-over items from previous sprint (if any)
Process
- Read sprint goal and check it's specific and measurable — flag if it's too vague
- Group tickets by theme or feature area
- Identify the critical path — which tickets must complete for the sprint goal to be met?
- Flag risks: tickets with unclear acceptance criteria, missing designs, unresolved dependencies
- Note carry-over items and whether they affect this sprint's goal
- Validate — Confirm the sprint goal is achievable given the ticket scope and capacity. If the critical path items alone would fill the sprint, flag it as overloaded.
Output Structure
Sprint [Number] Brief — [Dates]
Sprint Goal: [1-2 sentences — specific and measurable] Why This Sprint Matters: [Connect to quarterly OKR in 2-3 sentences]
What We're Building:
- [Theme 1]: [tickets and owners]
- [Theme 2]: [tickets and owners]
Critical Path: [The 2-3 tickets everything else depends on]
Risks to Flag:
- [Risk 1 + mitigation]
- [Risk 2 + mitigation]
Carry-over from Last Sprint: [List + impact on current goal]
Definition of Done: [Specific, agreed criteria for sprint success]
Quality Checks
- Sprint goal is specific enough to score pass/fail at the end of the sprint
- Critical path items are named — not just "the important ones"
- Every risk has a mitigation or owner (not just "this is a risk")
- Carry-over items are connected to their impact on this sprint's goal
- Definition of Done is agreed criteria, not a task list
Anti-Patterns
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-brief is a skill published in the GitHub repository cnfeat/top-pm-skills (48 stars, last pushed 3mo ago), licensed MIT. It adds 70 tokens to every session and 668 once invoked, about $0.0003 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 2026-09-03.

SpecStory Workthreads - a weekly work-thread rollup across a team's repos from SpecStory coding histories (any agent - Claude Code, Codex, Cursor, Gemini, and more).
