What problem does it solve? When a task matches no existing playbook—a large migration, an ambitious multi-part change, or work a human reviews after stepping away—this Skill designs a rigorous, auditable workflow before any code is written, so the effort doesn't drift or produce unverifiable results. ## Core Features & Use Cases - Playbook Design: Frames the task with a falsifiable definition of done, quantified scope, and a rigor level scaled to risk, then decomposes the work into atomic, independently-landable units. - Hypothesis Loop: Runs each unit as an experiment—state a hypothesis, make the smallest change, verify against the predicate on the real artifact, keep or revert—with VERIFIED, NOT VERIFIED, or INCONCLUSIVE verdicts. - Audit Trail: Logs every decision and unit in a canonical TSV via the show-me-your-work skill, with evidence links a reviewer can re-run, so a human can trust the work after stepping away. - Use Case: Migrating an API across dozens of call sites? The Skill sequences riskiest-unknown-first, builds the verification harness before the changes, and commits a decision trail alongside the diff for PR review. ## Quick Start Ask the agent to figure out a plan for migrating the payment module to the new API, with a decision log I can review afterward.
