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.

What it costs to keep this loaded
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 | $0.00091 | $0.02498 |
| Opus 5 | $0.00046 | $0.01249 |
| Sonnet 5 | $0.00018 | $0.00500 |
| Haiku 4.5 | $0.00009 | $0.00250 |
Grade A, and why
tool-design-sprint-readiness 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 9d 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 — 140 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Design Sprint Readiness
Assess whether a Design Sprint fits the team's current situation. Design Sprint failure modes are expensive: five consecutive days of a 4-7 person team, plus customer recruiting cost (typically 5 strangers paid honoraria), plus the prototype build. A 30-45 minute readiness diagnostic catches the failure modes before that commitment is made.
Family contract: docs/reference/skill-families/design-sprint-skills-contract.md. This skill is a member of design-sprint-skills and conforms to the family frontmatter and Decider Checkpoint requirements.
When to Use
- A team is considering starting a Design Sprint and needs a fast diagnosis before committing five days plus customer recruiting effort.
- A team has just completed a Foundation Sprint and is deciding whether the next test should be a Design Sprint, a smaller experiment, or direct build. The Founding Hypothesis is consumed as optional input context (no separate bridge skill artifact is required).
- An existing sprint commitment is on the calendar and the team wants to validate that prerequisites (Decider, customers, prototype medium) are in place.
- Re-running a Design Sprint after an inconclusive first sprint: use to confirm the new challenge framing and customer access are ready.
When NOT to Use
- The team has already decided to run the sprint and just needs the brief. Use
tool-design-sprint-briefinstead. - The team has no clear challenge and is still in discovery. Run problem framing or a Foundation Sprint first; a Design Sprint depends on a sprint-worthy challenge.
- Low-stakes tweaks where five days of team time would be disproportionate. Use a lighter experiment design instead.
- No customer access for Friday testing and no realistic recruiting plan. A Design Sprint that cannot test on Friday is just a four-day workshop with no learning event.
- No Decider available and one cannot be appointed. Design Sprint requires fast decisions Wednesday and pre-test Thursday; without authority the sprint produces options without commitment.
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.

tool-design-sprint-readiness is a skill published in the GitHub repository product-on-purpose/pm-skills (663 stars, last pushed yesterday), licensed Apache-2.0. It adds 91 tokens to every session and 2,498 once invoked, about $0.0005 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.

product-designer
Use when the user asks to review a design, critique a UI or mockup, give design feedback, or check a screen for usability and accessibility issues. Do NOT use for visual brand or aesthetic preference debates, or for reviewing copy before layout is settled.
design-sprint
Use when asked to "run a design sprint", "5-day sprint", "prototype in a week", "test ideas before building", or "Jake Knapp sprint". Helps teams go from problem to tested prototype in five days. The Design Sprint framework (created by Jake Knapp at Google Ventures) compresses months of work into one focused week.
hooked-model
Use when asked to "build habit-forming products", "Hooked model", "trigger action reward investment", "create sticky behavior loops", or "design habit loops". Helps design products that form unprompted user habits. The Hooked Model (created by Nir Eyal) explains how products create habits through Trigger, Action…
breadboarding
Turn a shaped solution into a breadboard: user actions, UI affordances, system responsibilities, and wiring so it can be sliced and implemented.
deck-open-slide-canvas
OpenDesign's architecture review: the local daemon + agent-runtime design, the tradeoffs, and the decision to lock. Built as a decision-grade product management deck for staff eng, tech leads, security.

Apply foundational design principles: affordances, signifiers, constraints, feedback, and conceptual models. Use when the user mentions "why is this confusing", "affordance", "error prevention", "discoverability", "human-centered design", "mental model", "mapping", "seven stages of action", "users keep making…
