Individual skill

decision-challenge

Use when a high-impact plan, migration or architecture claim needs a bounded adversarial challenge before commitment. Isolates claims from persuasion, attacks assumptions, reconciles doubts with evidence and emits proceed/hold/stop. NOT a finished-diff review (`review`/`code-review`), NOT SDD artifact consistency (`analyze`).

# decision-challenge — doubt with a stopping rule

Use this immediately before a consequential commitment: an irreversible migration, a production-auth change, a costly architecture bet, a launch exception, or a plan whose confidence is higher than its evidence. The purpose is to find the decision-changing doubt, not to perform scepticism forever.

This skill is read-only unless the user also asks to change the artifact. It emits a challenge record and a verdict. Finished code review stays with `../review/SKILL.md` or `../code-review/SKILL.md`; consistency across constitution/spec/plan/tasks stays with `../analyze/SKILL.md`.

## One bounded cycle
