Create Shape Up Pitch
Overview
Generate a pitch following the Shape Up methodology (Ryan Singer / Basecamp). A pitch defines the problem, sets a fixed time budget (appetite), sketches a solution at the right level of abstraction, identifies rabbit holes to avoid, and declares explicit no-gos. This gives teams enough direction to build without over-specifying the solution.
Workflow
- Read product context -- Scan
.chalk/docs/product/for the product profile, related PRDs, and JTBD docs. Check.chalk/docs/engineering/for architecture docs that inform feasibility. Understand the existing system before shaping new work.
- Parse the feature -- Extract from
$ARGUMENTSthe problem or feature to pitch. If$ARGUMENTSdescribes a solution rather than a problem, dig back to the underlying need and reframe.
- Determine the next file number -- Read filenames in
.chalk/docs/product/to find the highest numbered file. The next number ishighest + 1.
- Write the Problem section -- Describe the problem from the user's perspective. Include: who has this problem, when they encounter it, and what the current workaround is. Ground it in specific scenarios, not abstract statements.
- Set the Appetite -- Define the fixed time budget (typically 2 or 6 weeks in Shape Up). The appetite is a constraint, not an estimate. State what the team should be willing to spend and why that budget is appropriate for the value delivered.
- Sketch the Solution -- Describe the solution at fat-marker sketch level: broad strokes, key affordances, critical flows. Do not specify UI details, exact copy, or implementation. Show enough that a team can start building but has room to make design decisions.
- Identify Rabbit Holes -- List specific risks, technical unknowns, or scope traps that could consume the entire appetite. For each, explain why it is a risk and suggest how to avoid or de-risk it.
- Declare No-Gos -- Explicitly list what is NOT included in this pitch, even if someone might reasonably expect it. These are intentional scope cuts that keep the work within the appetite.
- Write the file -- Save to
.chalk/docs/product/<n>pitch<feature-slug>.md.
- Confirm -- Share the file path and highlight the biggest rabbit hole that needs attention before betting on this pitch.
Output
- File:
.chalk/docs/product/<n>pitch<feature-slug>.md - Format: Plain markdown with Problem, Appetite, Solution, Rabbit Holes, and No-Gos sections
- First line:
# Pitch: <Feature Name>
Anti-patterns
- Over-specified solution -- Wireframes, pixel-perfect mockups, and detailed specs defeat the purpose. The solution should be at fat-marker level -- broad strokes that leave room for the building team to make decisions.
- Appetite as estimate -- "We estimate this will take 4 weeks" is not an appetite. An appetite is a deliberate constraint: "This problem is worth at most 6 weeks. If we cannot solve it in 6 weeks, we will not do it."
- No rabbit holes section -- Every pitch has risks. If the rabbit holes section is empty, the pitch has not been shaped thoroughly enough. Revisit and think about what could go wrong.
- Problem described as absence of solution -- "We do not have feature X" is not a problem. "Users cannot accomplish Y, so they do Z workaround which costs them time" is a problem.
- No-gos that are obvious -- "We will not rewrite the entire backend" is not a useful no-go. No-gos should be things a reasonable person might expect to be included but that are intentionally cut.
