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.

Quality

Content

33%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The body is a well-organized but shallow overview: it explains what a Design Sprint is and when to use it, yet never instructs how to run one. The five-day workflow — the entire point of the skill — is absent, leaving Claude with decision criteria but no executable process.

Suggestions

Add a concrete Day 1–5 workflow section (e.g. Monday: map the problem and choose a target; Tuesday: sketch competing solutions; Wednesday: decide and write a storyboard; Thursday: build the prototype; Friday: test with 5 customers) so the skill actually instructs execution.

Add facilitation specifics: how to run each exercise, the Decider/Facilitator roles, timeboxes, and how to synthesize Friday's test results into a go/no-go recommendation.

Trim the "Domain Context" boilerplate, the company name-dropping, and the generic explanation of what a Design Sprint is — Claude already knows this — and merge "Resources" and "Further Reading" into one section under a consistent heading hierarchy.

DimensionReasoningScore

Conciseness

"This skill implements a proven product management framework... combines best practices from industry leaders" is pure padding, "it has been used by teams at Slack, Uber, Airbnb, LEGO, the New York Times" is name-dropping, and "A Design Sprint is a five-day process..." re-explains a well-known framework Claude already knows. The When to Use / When Not to Use bullets are lean, so it is mostly efficient — anchor 3, not 2, because padded passages are the minority.

3 / 5

Actionability

The when-to-use criteria and input requirements are concrete, but the core task — running the sprint — has no executable guidance: no day-by-day agenda, no exercises, no facilitation steps, no prototype/test instructions. This matches anchor 2 (high-level hints, specific steps missing) rather than 1, because the decision guidance and input list are genuinely actionable.

2 / 5

Workflow Clarity

The framework is defined as a five-day sequence ("By Friday, you'll have tested a realistic prototype"), yet the body never presents any sequence of steps — no Day 1–5 breakdown, no order of operations, no checkpoints or validation. This is anchor 1 (steps missing, no sequence); anchor 2 would require at least a rough sequence of the actual process.

1 / 5

Progressive Disclosure

No bundle files exist, so this is scored on body structure: lean, well-organized sections with clear headers and no content that should be split out to separate files. It falls short of 5 due to minor organization gaps — the heading hierarchy is inconsistent (## Domain Context and ## Input Requirements precede the top-level # Design Sprint title) and "Resources" and "Further Reading" are two fragmented trailing sections.

Description

90%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong description: explicit trigger phrases, clear what/when coverage, and a distinctive niche. The only weakness is that capabilities are stated as a single outcome ("problem to tested prototype in five days") rather than an enumeration of the concrete actions the skill performs.

Suggestions

Enumerate the concrete actions the skill performs, e.g. "Facilitates the five-day GV process: map the problem, sketch solutions, decide, build a prototype, and test with five customers" instead of the single outcome phrase.

Name the deliverable explicitly (e.g. "produces a tested clickable prototype and a go/no-go recommendation") so users know what they get by Friday.

Consider adding one or two more trigger variants users might say, such as "validate a product idea" or "sprint workshop".

DimensionReasoningScore

Specificity

"Helps teams go from problem to tested prototype in five days" gives one outcome-level action rather than a list of concrete actions (mapping, sketching, deciding, prototyping, testing are never named). It is clearly more concrete than anchor 2's domain-only naming but does not list the several specific actions required for a 4.

3 / 5

Completeness

Explicitly answers 'when' with a "Use when asked to..." clause containing concrete trigger phrases, and 'what' with "go from problem to tested prototype in five days" and "compresses months of work into one focused week". Both halves are clearly and explicitly stated, matching the top anchor.

5 / 5

Trigger Term Quality

Five natural, quoted phrases users would actually say — "run a design sprint", "5-day sprint", "prototype in a week", "test ideas before building", "Jake Knapp sprint" — covering synonyms, timeframe variants, and the creator's name. This matches the comprehensive natural-term coverage of the top anchor.

5 / 5

Distinctiveness Conflict Risk

"design sprint" and "Jake Knapp sprint" carve out a clear niche with distinct triggers; there is minimal risk of this firing for a generic PM, prototyping, or UX-research skill.
