What problem does it solve? When a task matches no existing playbook—a large migration across many call sites, an ambitious multi-part change, or work a human reviews after stepping away—ad-hoc execution produces unverifiable results and no decision trail. This Skill designs a rigorous, auditable workflow before any code is written. ## Core Features & Use Cases - Playbook Design: Frames the task with a falsifiable definition of done, quantified scope, and a rigor level scaled to blast radius, then decomposes work into atomic, independently-landable units. - Hypothesis Loop: Runs each unit as an experiment—state a hypothesis, make the smallest change, measure against the predicate on the real artifact, and keep or revert based on evidence. - Audit Trail: Logs every decision and unit in a canonical TSV via the show-me-your-work skill so a reviewer can audit the run after stepping away. - Use Case: You need to migrate an API pattern across hundreds of call sites. The Skill sequences riskiest-unknown-first units, builds a verification harness from the pre-change baseline, and produces a decision log you can review in the PR. ## Quick Start Ask the agent to figure out a plan for migrating the legacy authentication module across all services with a verifiable audit trail.
