Day 2 end capstone move of a Foundation Sprint. Compresses the sprint's full strategic frame into a single canonical sentence (the Founding Hypothesis) plus an assumption scorecard, why-we-believe, what-could-prove-us-wrong, and recommended next validation step. Use after Magic Lenses is signed. Strict canonical template; paraphrase is not accepted in v0.1.0. The Founding Hypothesis is the spine artifact the sprint exists to produce.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
<!-- PM-Skills | https://github.com/product-on-purpose/pm-skills | Apache 2.0 --> # Foundation Sprint Founding Hypothesis Day 2 end of a Foundation Sprint. The team compresses the full sprint output into a single canonical sentence plus a testable scorecard. This is the artifact the sprint exists to produce; everything before this skill was preparation. Without a ratifiable Founding Hypothesis, the sprint failed. Family contract: [`site/src/content/docs/reference/skill-families/foundation-sprint-skills-contract.md`](../../site/src/content/docs/reference/skill-families/foundation-sprint-skills-contract.md). This skill is a member of `foundation-sprint-skills`. ## When to Use - Day 2 end of a Foundation Sprint. - Magic Lenses is signed; top bet and backup are named. - The team has 30-45 minutes left in Day 2 and the energy to write the sentence carefully. ## When NOT to Use - Magic Lenses did not produce a clear top bet. Return to Magic Lenses; the Founding Hypothesis cannot stabilize on an unstable top bet. …

How to install
mdr add product-on-purpose/pm-skills/tool-foundation-sprint-founding-hypothesis@sha256:9b685a8386c833aeThe line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
