Day 1 morning of a Foundation Sprint. The team makes four foundational choices explicit: who the product is for, what important problem it solves, why this team has a right to win, and what customers do today instead. The output is one coherent strategic frame, not four separable decisions.
Family contract: docs/reference/skill-families/foundation-sprint-skills-contract.md. This skill is a member of foundation-sprint-skills.
A single bundled artifact with five sections:
The artifact is treated as one coherent output, not four separate ones. The team signs off on the bundled frame, not on the components in isolation. See references/TEMPLATE.md for the canonical structure and references/EXAMPLE.md for the Brainshelf example.
Each sub-decision uses tool-note-and-vote (the silent ideation + voting + Decider supervote protocol). The skill structures the sequence but the decision protocol is the standalone note-and-vote tool.
The team produces 3-7 candidate customer descriptions through silent ideation, then votes, then the Decider supervotes one. The chosen customer MUST be specific (not "SaaS PMs" but "PMs at Series-B SaaS companies between 20 and 100 engineers"). The skill rejects vague segments and prompts the team to add markers until the description names someone the team can recognize.
The team names 3-7 candidate pains the chosen customer experiences. Vote, then Decider supervote. The chosen problem MUST be painful enough to drive switching from current behavior (including doing nothing). Mild annoyances are not Important Problems; the skill enforces this by asking explicitly: "What does the customer currently do, and why would they leave it for our solution?"
The team enumerates its specific edges: capabilities, insights, relationships, data, technology, distribution, timing. Vote to surface the top 2-3 (multi-vote), Decider confirms. The skill rejects generic advantages ("great team," "passionate") and prompts for specific evidence ("Sam previously built X at Y company"; "Riley has a 12k-member network in our target segment").
The team maps the full alternative space: direct competitors, substitute workflows, manual workarounds, internal tools, and "do nothing." For each, the team notes what customers use it for and why people leave (or stay). The skill enforces inclusion of "do nothing" as a competitor; many teams forget that inertia is often the strongest alternative.
| Input | What the skill does with it |
|---|---|
| Sprint brief | Reads the Decision Target to scope which customers and problems are in-scope; out-of-scope candidates are flagged before voting |
| Customer/market context packet | Pre-populates the silent ideation board with previously-surfaced candidates so the team doesn't reinvent them |
| Competitor knowledge | Pre-populates the alternative map with already-known competitors; the team adds and discusses rather than starts cold |
| Team advantage notes | Surfaces the team's existing self-assessment; voting refines and prioritizes |
The Decider's job during Basics is to:
A Decider who blesses everything without challenge is not adding value; a Decider who overrides without rationale is not building trust.
Prerequisites: tool-foundation-sprint-brief. The Brief's Decision Target tells the skill which customer-problem space is in-scope.
The skill invokes tool-note-and-vote four times (once per sub-decision). Each invocation produces its own decision record; the four traces are aggregated into the bundled artifact.
Next invocation in the sprint: tool-foundation-sprint-differentiation on Day 1 afternoon, immediately after lunch.
This skill ends with a Decider Checkpoint in references/TEMPLATE.md. The Decider signs off on the bundled artifact as a coherent strategic frame, not on the components individually. Without sign-off, Differentiation cannot start cleanly because the inputs are still under negotiation.
