Day 2 afternoon move of a Foundation Sprint. Evaluates the candidate approach set through multiple lenses (4 classic plus at least 1 custom) to surface trade-offs, identify consistent winners and contradictions, and produce a top bet plus a backup plan. Use after Approach Options is signed. Lens scoring is a sense-making tool, not mathematical truth; arbitrary precision is a smell.

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.

# Foundation Sprint Magic Lenses

Day 2 afternoon of a Foundation Sprint. The team evaluates each candidate approach from multiple perspectives, surfaces contradictions, and produces a top bet plus a backup plan. The Decider names both; without an explicit backup, invalidation of the top bet sends the team back to ambiguous debate.

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 afternoon of a Foundation Sprint.
- Approach Options is signed; the team has 3-7 candidate approaches advancing.
- The team has at least 1 team-specific custom lens prepared (per ratified spec decision; classic lenses alone are insufficient).

## When NOT to Use

- Approach Options is unresolved or under-numbered (fewer than 3). Force a third option through the approach-options skill first.

How to install

The exact contents, by fingerprint
mdr add product-on-purpose/pm-skills/tool-foundation-sprint-magic-lenses@sha256:a7e1000ffb53921c

The 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.
