What it does

Tool Design Sprint Sketch is an agent skill from product-on-purpose/pm-skills. Day 2 (Tuesday) move of a Design Sprint that structures lightning demos and the four-step independent solution sketch protocol (Notes, Ideas, Crazy 8s, Solution Sketch). Each team member produces one solution sketch individually; the skill orchestrates the day but does not author the sketches themselves. Use Tuesday morning after Monday's target moment is locked. Output is the lightning demo board, sketch assignments, and the cohort of independent sketches that become Wednesday's heat-map material.

Its SKILL.md is about 2.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `HISTORY.md`, `references/EXAMPLE.md` and `references/TEMPLATE.md`).

The repository describes itself as: 68 plug-and-play, best-practice product management skills for AI agents: 30 Triple Diamond phase + 11 foundation + 12 utility + 15 tool (Foundation Sprint + Design Sprint). Plus… The licence is Apache-2.0.

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Lightning demo board: each team member presents 3 demos (3 minutes each); the Facilitator extracts the reusable pattern from each demo…
  2. Sketch assignment plan: divide (each person sketches a different part of the target moment) or swarm (everyone sketches the same target)…
  3. Four-step sketches from each team member: Notes (20 min reviewing Monday output + lightning demos), Ideas (20 min rough doodles), Crazy 8s…
  4. Recruiting tracker update: Riley (or the recruiter) confirms Friday slots; surfaces any cancellations and triggers buffer-slot activation…

What it can do on your machine

Read from SKILL.md and the folder at commit 1cef1a9. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • gv.com
    • character.vc
    • designsprintkit.withgoogle.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Tool Design Sprint Sketch loads about 2.1k tokens when it runs, and up to ~5.4k if it reads all its reference files. Until then it costs about 132 tokens; SKILL.md has 945 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~132
When it runs · the whole SKILL.md, loaded when a task matches
~2.1k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~5.4k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Design Sprint Sketch (Tuesday)

Structure Tuesday's solo-but-together work. Each team member, working independently and silently, produces lightning demos in the morning and a four-step solution sketch in the afternoon. The skill structures the activity; the humans produce the sketches. Wednesday's heat-map orientation depends on having a cohort of independent sketches that did NOT contaminate each other through group brainstorming.

Family contract: docs/reference/skill-families/design-sprint-skills-contract.md. This skill is a member of design-sprint-skills.

When to Use

  • It is Day 2 of the Design Sprint and Monday's Map and Target artifact is signed off.
  • Each team member brings at least 3 lightning demo sources (existing products, references, analogies that bear on the challenge).
  • The team has accepted the silent-independent-sketching constraint and will NOT lapse into group brainstorming.
  • Sketches are due Tuesday end-of-day for Wednesday morning heat-map.

When NOT to Use

  • Monday is not closed. Return to tool-design-sprint-map-and-target.
  • The team's instinct is to brainstorm as a group. Sprint method explicitly avoids this; if the team will not commit to independent work, the sprint will not produce diverse sketches and the heat-map becomes a popularity contest.
  • The sketch step is being treated as the prototype. Sketches are concept exploration on paper or Figma frames, not Thursday's working prototype.
  • Sketches are due Tuesday morning. Tuesday is the full day; rushing to lunch produces sketches the team cannot read Wednesday.

What This Skill Produces

A single bundled artifact with four sections:

  1. Lightning demo board: each team member presents 3 demos (3 minutes each); the Facilitator extracts the reusable pattern from each demo into a one-line note. Result is a board with 12-21 patterns (4-7 team members x 3 demos).
  2. Sketch assignment plan: divide (each person sketches a different part of the target moment) or swarm (everyone sketches the same target). Default is swarm for v0.1 Design Sprints; divide is for teams running their second sprint with the same target who want to broaden coverage.
  3. Four-step sketches from each team member: Notes (20 min reviewing Monday output + lightning demos), Ideas (20 min rough doodles), Crazy 8s (8 minutes, 8 variations of the strongest Idea), Solution Sketch (30-90 min final 3-panel storyboard-style sketch).
  4. Recruiting tracker update: Riley (or the recruiter) confirms Friday slots; surfaces any cancellations and triggers buffer-slot activation if needed.

See references/TEMPLATE.md for the canonical structure and references/EXAMPLE.md for the Brainshelf book-catalog Tuesday artifact.

Tuesday Time Structure

The full Tuesday workshop is approximately 7 hours (09:00-12:30 + 13:30-17:00). The skill's bundled artifact emerges across the day:

  • 09:00-09:15: Welcome + Monday recap + Tuesday agenda
  • 09:15-10:45: Lightning demos (each person 3 demos x 3 min + 1 min Facilitator extraction = ~12 min per person; 4-person team = ~50 min; 7-person team = ~85 min)
  • 10:45-11:00: Break
  • 11:00-11:30: Sketch assignment plan + Notes step (each person silently reviews Monday output and lightning demo board)
  • 11:30-12:30: Ideas step (each person silently doodles ideas in their notebook or Figma frame)
  • 12:30-13:30: Lunch + (in parallel) recruiting tracker check-in
  • 13:30-13:40: Crazy 8s (8 minutes, 8 variations of strongest Idea)
  • 13:40-15:30: Solution Sketch (final 3-panel sketch; everyone silent; Facilitator times)
  • 15:30-15:45: Break
  • 15:45-16:30: Sketches collected + named + photographed for Wednesday board; sketcher attribution hidden (Wednesday's heat-map is blind)
  • 16:30-17:00: Day-end check-in; confirm sketches uploaded; confirm Wednesday morning attendance

This skill's 180-minute timebox covers the Facilitator-led portions (lightning demos + assignment + collection). The silent sketch steps (Notes, Ideas, Crazy 8s, Solution Sketch) are individual work and run in parallel; the team is together in the room (or video call) but not collaborating.

Common Pitfalls

  • Group brainstorming. The single most common failure mode. The Sprint method explicitly forbids group sketching because it produces sketches that converge on the loudest voice, not the best idea. Facilitator's job is to enforce silence during sketch steps.
  • Sketches not concrete enough. A solution sketch must be understandable Wednesday morning WITHOUT the artist explaining it. If the heat-map team has to ask "what is this?", the sketch failed the readability bar.
  • Skipping lightning demos. Lightning demos are not optional warm-up; they inject outside patterns the team would not have generated. Skipping them produces inward-looking sketches.
  • Demo facilitator failing to extract reusable patterns. Each demo's reusable pattern must be captured (not the whole demo). "Spotify's home screen" is not a pattern; "feed of personalized cards with one-tap action" is.
  • Sketching the prototype. The solution sketch is a concept; the prototype is Thursday's build. Sketches that try to be the prototype are over-detailed in the wrong dimensions (visual polish, copy) and under-detailed in the right ones (interaction sequence, user reaction).
  • Sketcher attribution leaked into Wednesday heat-map. Wednesday's heat-map is blind (no sketcher names visible) so the team votes on the sketch, not the sketcher. If sketches arrive on Wednesday with names attached, the Facilitator strips them.

Cross-Skill Usage

Prerequisites: tool-design-sprint-map-and-target. Sketch consumes Monday's target moment as the design target for the four-step sketch protocol. Without a target moment, sketches diverge with no shared direction.

This skill does NOT invoke tool-note-and-vote. Tuesday has no voting moment; all voting happens Wednesday after sketches are produced.

Next invocation in the sprint: tool-design-sprint-decide-and-storyboard Wednesday morning.

Canonical Sources

Decider Checkpoint

This skill ends with a Decider Checkpoint in references/TEMPLATE.md. There is NO mid-day Tuesday decision; the Decider's role Tuesday is to be a sketcher among other sketchers (the Decider sketches independently like everyone else). The end-of-Tuesday Decider Checkpoint is a logistics confirmation: all sketches collected, attribution stripped, Wednesday morning attendance confirmed. The substantive Decider call comes Wednesday morning at the supervote.
