What problem does it solve? When a task fits no existing playbook—like a large migration or an ambitious multi-part change—this Skill designs a bespoke, auditable workflow instead of improvising, so a human can review the work after stepping away. ## Core Features & Use Cases - Playbook Design Before Code: Frames a falsifiable done predicate, quantifies scope, sets a rigor level, and decomposes work into atomic, independently-landable units sequenced riskiest-first. - Hypothesis Loop with Audit Trail: Runs each unit as an experiment verified against the real artifact, logging every decision in a canonical TSV trail via the show-me-your-work skill. - HOLD Discipline: Stops and returns the gap when required inputs are missing, rather than guessing or treating inconclusive results as passes. - Use Case: You face a repository-wide migration with no existing playbook. The Skill frames the done predicate, builds a verification harness from the pre-change baseline, executes units under the loop, and hands back a committed decision trail for review. ## Quick Start Ask the agent to figure out a plan for migrating the legacy billing module to the new API, with a falsifiable done predicate and a decision log you can review afterward.
