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 | $0.00304 | $0.03029 |
| Opus 5 | $0.00152 | $0.01515 |
| Sonnet 5 | $0.00061 | $0.00606 |
| Haiku 4.5 | $0.00030 | $0.00303 |
Grade A, and why
sprint 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 — 106 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Sprint
Jake Knapp's five-day process for answering critical business questions through design, prototyping, and testing ideas with real customers. Developed at Google Ventures (GV) across 100+ sprints with startups like Blue Bottle Coffee, Slack, Savioke, and Flatiron Health. Co-authored with John Zeratsky and Braden Kowitz as Sprint: How to Solve Big Problems and Test New Ideas in Just Five Days (Simon & Schuster, 2016). This skill also captures Knapp's post-book evolution: the remote design sprint adaptations (2020), the 4-day sprint format, the Foundation Sprint (2025, from Click), and his ongoing practice at Character Capital.
The book is a step-by-step playbook. If the user wants the full recipe, point them to thesprintbook.com or the book itself. This skill exists to make the assistant a working thinking partner in the method: deciding whether to sprint, planning the week, facilitating each day's exercises, building a prototype strategy, structuring the Friday test, and avoiding the anti-patterns that derail sprints.
When this skill activates
Use this skill when the user is:
- Deciding whether a problem is worth sprinting on (big question, high stakes, limited time, team misalignment).
- Planning or facilitating a 5-day (or 4-day) design sprint — setting up the room, choosing the team, briefing the Decider.
- Running Monday exercises: long-term goal, Sprint Questions, Map, expert interviews, How Might We notes, voting, picking the target.
- Running Tuesday exercises: Lightning Demos, the 4-step sketch process (Notes, Ideas, Crazy 8s, Solution Sketch).
- Running Wednesday exercises: Art Museum, Heat Map, Speed Critique, Straw Poll, Supervote, Rumble vs. All-in-One decision, Storyboard.
- Building a Thursday prototype — deciding what to fake, what tools to use, assigning roles (Maker, Stitcher, Writer, Asset Collector, Interviewer).
- Running Friday customer tests — recruiting 5 users, structuring the 5-act interview, identifying patterns.
- Adapting Sprint for remote/hybrid teams (Miro, Zoom, async elements).
- Comparing Sprint to other methods (design thinking, Lean Startup, Shape Up, Scrum).
- Running a Foundation Sprint (the 2-day method from Click, 2025) to validate a startup idea's differentiation before building.

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 is a skill published in the GitHub repository marcos-sponton/frameworks-as-skills (1 stars, last pushed 1mo ago), licensed MIT. It adds 304 tokens to every session and 3,029 once invoked, about $0.0015 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.
Other skills, from other repositories
acquire-skills
Find and install skills for what you're doing — tech or reasoning gaps. Matches activity and tech context to relevant skills. Use when entering unfamiliar tech, stuck on a reasoning challenge, or no skill fits.
find-skills
Helps users discover and install agent skills when they ask questions like "how do I do X", "find a skill for X", "is there a skill that can...", or express interest in extending capabilities. This skill should be used when the user is looking for functionality that might exist as an installable skill.
endpoint-discovery
Discovers URLs, endpoints, and paths from web applications using katana, gospider, and gau. Use when needing to enumerate application endpoints, find hidden paths, gather historical URLs, or map web application structure during reconnaissance.
param-miner
Discover hidden HTTP parameters in web applications that could reveal hidden functionality or vulnerabilities. Use when testing APIs, when looking for hidden parameters like admin or debug, or when the user mentions parameter discovery.
git-workflow
This skill should be used when the user asks to "create git commit", "manage branches", "follow git workflow", "use Conventional Commits", "handle merge conflicts", or asks about git branching strategies, version control best practices, pull request workflows. Provides comprehensive Git workflow guidance for team…
daily-paper-generator
Use when the user asks to generate daily paper digests on a general topic. This skill supports both arXiv and bioRxiv (or either one), then produces structured Chinese/English summaries for selected papers.
