Best-of-N Selection and Proof

Use this skill when a task has several plausible solutions, a wrong choice is costly, and a deterministic check or independent reviewer can evaluate the selected result. Do not use it for mechanical work with one clear implementation and a direct acceptance test.

Inputs to collect before generation

• Task scope, exclusions, repository revision, environment, permissions, and budget.
• Acceptance criteria, mandatory failure conditions, and executable checks.
• A rubric with weights, observable anchors, passing threshold, tie-breaker, candidate count or predeclared batch schedule, and stop rule.
• The selected TESTING.md path. Start from the portable proof-log template.

If any item is missing, return needs_contract and list the missing fields. Do not generate candidates first and invent the rubric afterward.
