tool-design-sprint-readiness — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited tool-design-sprint-readiness (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

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.
tool-design-sprint-brief instead.A single bundled artifact with six sections:
See references/TEMPLATE.md for the canonical structure and references/EXAMPLE.md for a worked example using the Brainshelf book-catalog thread.
The skill runs an inference pass over these inputs to produce the verdict:
| Input | What the skill does with it |
|---|---|
| Challenge description | Determines whether the challenge is sprint-worthy (specific enough to prototype in 4 days; big enough to justify 5 team-days) |
| Existing hypothesis (from Foundation Sprint or elsewhere) | Confirms there is a testable bet, not exploratory discovery. Highest-risk assumption from the FS scorecard becomes a candidate sprint question |
| Customer access status | Critical. Without realistic Friday customer access, the sprint cannot test |
| Decider name and full-week availability | Confirms Decider can attend at least Monday morning, Wednesday morning (heat map + supervote), and Friday afternoon (Decider review); ideally all 5 days |
| Team composition draft | Checks roster against the 4-7 person band; flags missing roles (engineering for prototype build, design for sketching, researcher or PM for customer interviews) |
| Prototype medium feasibility | Confirms a 1-day prototype is achievable in the chosen medium (clickable, slideware, service role-play, paper, physical mock) |
| (Optional) Logistics constraints | Confirms five consecutive days can actually be cleared by all attendees |
If a load-bearing input is missing or low-confidence, the skill flags it explicitly and proposes how to close the gap before Monday.
The skill evaluates the team against these eight criteria, drawn from Sprint (Knapp, Zeratsky, Kowitz), GV "Is Your Idea Sprint-Worthy?", and Character Capital's Design Sprint guide:
| Pattern | Verdict |
|---|---|
| All 8 criteria met cleanly | Go |
| 1-2 criteria are "yellow flags" but addressable in the 1-2 weeks before Monday | Conditional Go with documented prep |
| 3 or more criteria fail, or any of 1, 3, or 6 is a hard fail | Wait with recommended prerequisite work |
Treat the criteria as load-bearing, not a checklist to game. A team that papers over no-customer-access with "we'll figure it out by Thursday" should get a Wait, not a Conditional Go.
This skill is the entry point of the design-sprint-skills family. It has no prerequisites (the metadata.prerequisites field is intentionally empty).
When the verdict is Go, the natural next invocation is tool-design-sprint-brief to lock challenge, team, recruiting plan, prototype medium, and logistics. When the verdict is Wait, the team typically does prerequisite work (problem framing, Foundation Sprint, customer recruiting setup) before re-invoking this skill.
A team coming directly from a Foundation Sprint should bring the Founding Hypothesis as input context. The hypothesis's highest-risk assumption (typically marked in the FS assumption scorecard) becomes the lead candidate sprint question for tool-design-sprint-brief (which locks the sprint questions); tool-design-sprint-map-and-target on Monday then refines the locked questions during the morning. No bridge skill exists or is required; the narrative handoff is described in _workflows/foundation-to-design.md and in both user guides.
tool-note-and-vote may be invoked once during the readiness conversation if the team disagrees on whether a Design Sprint is the right tool (vs. a smaller experiment or direct build). In practice, the diagnostic is usually conclusive.
This skill ends with a Decider Checkpoint in references/TEMPLATE.md. The Decider signs off on the verdict (Go / Conditional Go / Wait), accepts the diagnosis, and explicitly commits to the load-bearing attendance windows. Without Decider sign-off, the verdict is advisory; with sign-off, it is the commitment that triggers (or postpones) the sprint and the recruiting work.
