What problem does it solve? Turning an accepted spec or plan into actionable work items is error-prone: slices are often horizontal, dependencies are implicit, and tickets lack the context an engineer needs to start cold. This Skill decomposes a plan, spec, or conversation into vertical tracer-bullet tickets, each declaring its blocking edges, file footprint, and acceptance criteria. ## Core Features & Use Cases - Vertical Slice Decomposition: Splits work into tracer-bullet tickets that cut through every layer (schema, API, UI, tests) so each ticket is independently demoable. - Dependency Modeling: Every ticket declares its blocking edges and a parallel-safe marker based on file footprint overlap, enabling safe sequential or worktree-parallel execution. - Ticket Publishing: Writes one file per ticket under docs/handoff/<version>/phase-N/tickets/ with a Conventional Commit message, standing rules, and acceptance checkboxes. - Use Case: After accepting a spec in docs/specs/, run this Skill to produce a numbered, dependency-ordered set of ticket files that an engineer (or agent) can execute one at a time without further context. ## Quick Start Ask the agent to break the accepted spec in docs/specs into tracer-bullet tickets with blocking edges and publish them as individual ticket files.
