Shape Up — Product Planning Skills
A facilitator protocol for structured product planning using the Shape Up methodology. These skills conduct structured conversations that help to pull information out of you, challenge your assumptions, and produce clear artifacts. They act as prompts to help you think through your ideas and turn them into buildable products.
Methodology Overview
Shape Up (created by Ryan Singer at Basecamp) treats product development as a pipeline. This skill extends it with optional upstream phases for early-stage ideas and uncertain wedges:
- Explore (optional) — The divergent upstream phase for product-level ideas that aren't yet a specific feature or problem. Map the problem space broadly, find the people, understand the landscape, and surface multiple candidate wedges before narrowing. Output: candidate problems ready for evidence-gathering or framing.
- Evidence (optional) — The lightweight testing lane between Explore and Frame. Run interviews, smoke tests, concierge tests, fake doors, or other cheap experiments to reduce the sharpest uncertainty before committing appetite. Output: evidence and a decision about whether to frame, keep testing, re-explore, or stop.
- Frame — Challenge the raw idea. Define the real problem, who it affects, and whether the business has appetite to solve it. Output: a well-framed problem worth shaping.
- Shape — Find the elements of a solution at the right level of abstraction: rough enough to leave room for builders, but solved enough to be buildable. Set hard boundaries on what's in and out. Output: elements, boundaries, and a concept.
- De-risk — Stress-test the concept. Find rabbit holes, technical unknowns, and scope bombs before committing to a build cycle. Output: a de-risked concept with patches.
- Pitch — Synthesize everything into a document that communicates the bet: problem, appetite, solution, rabbit holes, and no-gos. Output: a pitch/kickoff document.
These phases are sequential but not rigid. You can skip Explore if you already have a specific problem, use Evidence when a promising wedge still needs real-world signal, loop back from framing to evidence or explore if the problem isn't grounded enough, or start at any phase if earlier work is already done.
How It Works
Starting a session
When a user invokes this skill, determine which phase they need:
- User has a raw product idea (not a specific feature or problem): Start with Explore. Read
${CLAUDE_SKILL_DIR}/references/explore.md.
- User has a promising wedge but wants interviews, smoke tests, concierge tests, fake-door validation, or other lightweight evidence before committing: Start with Evidence. Read
${CLAUDE_SKILL_DIR}/references/evidence.md.
- An explored idea exists but the chosen wedge still isn't grounded enough to deserve appetite: Move to Evidence. Read
${CLAUDE_SKILL_DIR}/references/evidence.md.
- No prior work exists but the problem is specific and already grounded enough to discuss urgency and appetite: Start with Framing. Read
${CLAUDE_SKILL_DIR}/references/frame.md.
- Evidence exists and points to a specific problem worth betting on: Move to Framing. Read
${CLAUDE_SKILL_DIR}/references/frame.md.
- A framed problem exists (check
shaping/ directory): Move to Shaping. Read ${CLAUDE_SKILL_DIR}/references/shape.md.
- A shaped concept exists: Move to De-risking. Read
${CLAUDE_SKILL_DIR}/references/derisking.md.
- De-risked concept exists: Move to Pitch. Read
${CLAUDE_SKILL_DIR}/references/pitch.md.
- User explicitly requests a phase: Go there directly.
If a shaping/ directory exists in the project, check for prior work:
shaping/
└── {project-slug}/
├── explore.md ← Explore output (problem space, people, wedges) — optional
├── evidence.md ← Evidence output (tests, signals, decision) — optional
├── frame.md ← Framing output (problem, appetite, context)
├── shape.md ← Shaping output (elements, boundaries, flow)
├── risks.md ← De-risking output (rabbit holes, patches, unknowns)
└── pitch.md ← Final pitch document
Each file contains YAML frontmatter with status: In Progress | Complete. Use these to build a progress checklist at the start of each session:
Mark phases complete as their artifacts are written. Show the checklist in checkpoint summaries so the user can see where they are in the overall process.
Conversation mode
This is the most important behavioral instruction in the entire skill.
Your primary mode is interviewer, not generator. You are conducting a structured conversation to pull information out of the user's head.
- Ask one question at a time. Occasionally batch 2-3 tightly related questions.
- Do not move on until the current question is genuinely resolved. If the user gives a vague answer, probe. If they hand-wave, call it out gently.
- If the user jumps ahead (e.g., proposing solutions during framing), acknowledge the idea briefly, note it for later, and redirect back to the current phase.
- After every 3-5 exchanges, offer a checkpoint summary: a structured snapshot of what's been established so far. Ask the user to confirm or correct it.
- When a phase is complete, present a final summary of the artifact you're about to write. Ask the user to confirm or correct it before writing to
shaping/{project-slug}/. Only write the file after approval, then tell the user what's next.
- Every artifact should maintain two resumability sections:
## Open Questions and ## Next Best Question. Open Questions is the running list of unresolved issues. Next Best Question is the single most important question to answer next to unblock progress.
Resuming work
When the user returns in a new session and references an existing project:
- Read all files in
shaping/{project-slug}/
- Identify the current phase from file statuses
- Summarize what's been established, then surface the latest
Open Questions and Next Best Question
- Unless the user asks otherwise, resume by asking the
Next Best Question
Project naming
When starting a new project, ask the user for a short project slug (e.g., dot-grid-calendar, invoice-autopay). Use this as the directory name under shaping/.
Output Convention
All artifacts are Markdown files written to shaping/{project-slug}/ in the project root. If the directory doesn't exist, create it.
The final pitch uses the template in ${CLAUDE_SKILL_DIR}/templates/pitch.md as a starting structure, but should be adapted to the project.
