What problem does it solve? Turning a vague objective into a plan a fresh coding session can execute without re-asking questions is slow and error-prone. This Skill scopes the work, researches load-bearing behavior, resolves repository standards, removes ambiguity, and posts a versioned execution plan to Jira or GitHub Projects so implementation can start from an approved, self-contained specification. ## Core Features & Use Cases - Premise and prior-work validation: Checks whether the goal is already delivered, invalidated, or owned by sibling work before spending research effort, and shelves the task with evidence when the premise is gone. - Delegated research with verification: Uses breadth sweeps and end-to-end traces through sub-agents, resolves standards and risk lenses, and converts each risk lens into a verification obligation with named evidence. - Adversarial plan review: Pressure-tests the core design decision through a debate pass and runs a spec-gate review of the drafted plan before sign-off, dispositioning every finding. - Versioned plan publishing: Posts the approved plan as a single new tracker comment split into a human sign-off half and a mechanical /sy:ship half, then marks the task ready. - Use Case: You have a ticket saying "add idempotent webhook retries." Run the spec skill against it; it researches the codebase, debates the design, and posts an execution plan with file anchors, invariants, and acceptance criteria that /sy:ship can implement directly. ## Quick Start Ask the AI to spec the task: turn ticket PROJ-123 into an execution-ready plan with research, standards, and verification obligations.
