Get Started Free →Pre-sprint diagnostic that determines whether a team should run a Foundation Sprint now, postpone it, or do prerequisite work first. Produces a Go / Conditional Go / Wait verdict with diagnosis, recommended preconditions, attendee list, and pre-sprint activities. Use when a team is considering starting a Foundation Sprint and wants a fast yes/no diagnosis before committing two days of facilitated work.

Assess whether a Foundation Sprint fits the team's current situation. Most sprints that fail were sprints that should not have been run. A 30-45 minute readiness diagnostic catches that failure mode before two days of facilitated work are spent.
Family contract: docs/reference/skill-families/foundation-sprint-skills-contract.md. This skill is a member of foundation-sprint-skills and conforms to the family frontmatter and Decider Checkpoint requirements.
tool-foundation-sprint-brief instead.A single bundled artifact with five sections:
See references/TEMPLATE.md for the canonical structure and references/EXAMPLE.md for a worked example using the Brainshelf book-catalog thread.
The skill runs an inference pass over these inputs to produce the verdict:
| Input | What the skill does with it | |---|---| | Initiative description | Determines whether a Foundation Sprint is the right tool (vs problem framing, customer research, or a Design Sprint) | | Team composition draft | Checks roster against the Foundation Sprint role requirements; flags missing roles | | Decider name and availability | Confirms Decider can attend both days; flags partial availability as Conditional Go risk | | Existing customer/market knowledge level (self-assessed 1-10) | Below 5 indicates deep discovery is needed first; 5-7 indicates Conditional Go with research prep; 8+ indicates Go | | (Optional) Existing competitor and alternative knowledge | Flags gaps that can be closed by overnight prep | | (Optional) Logistics constraints | Confirms two days can actually be cleared |
If a load-bearing input is missing or low-confidence, the skill flags it explicitly and proposes how to close the gap before the sprint.
The skill evaluates the team against these eight criteria, drawn from Knapp/Zeratsky (Click) and Character Capital's Foundation Sprint guide:
| Pattern | Verdict | |---|---| | All 8 criteria met cleanly | Go | | 1-2 criteria are "yellow flags" but addressable in evening prep | Conditional Go with documented prep | | 3 or more criteria fail, or any of 1-4 is a hard fail | Wait with recommended prerequisite work |
Treat the criteria as load-bearing, not a checklist to game. A team that papers over a real gap with "yes, technically" should get a Conditional Go with the gap surfaced.
This skill is the entry point of the foundation-sprint-skills family. It has no prerequisites (the metadata.prerequisites field is intentionally empty).
When the verdict is Go, the natural next invocation is tool-foundation-sprint-brief to set up the sprint logistics. When the verdict is Wait, the team typically does prerequisite work (problem framing, customer research) before re-invoking this skill.
tool-note-and-vote may be invoked once during the readiness conversation if the team disagrees on whether a Foundation Sprint is the right tool. In practice, this is rare; the diagnostic is usually conclusive.
This skill ends with a Decider Checkpoint in references/TEMPLATE.md. The Decider signs off on the verdict (Go / Conditional Go / Wait) and explicitly accepts the diagnosis. Without Decider sign-off, the verdict is advisory; with sign-off, it is the commitment that triggers (or postpones) the sprint.
