What problem does it solve? Teams often jump from a design doc straight into coding, leaving implementation unplanned, unestimated, and unreviewed. This Skill turns an approved design document and codebase discovery report into a concrete, reviewable execution plan with task breakdowns, token estimates, and an explicit approval gate before any build work begins. ## Core Features & Use Cases - Cold-executor trio generation: Produces plan.md, spec.md, and prompt.md from versioned templates so a fresh AI session can re-execute the work without prior context. - Task decomposition and work packages: Breaks work into 2-5 minute leaf tasks with file paths, requirement traceability, acceptance criteria, and dependency graphs, grouped into bounded packages. - Mandatory gates and reviews: Enforces a token-estimate gate, cross-section analysis, two-stage adversarial review, and a founder approval pause before BUILD. - Use Case: After finishing a design doc for a new API endpoint, run the planner to get an ordered task list with verification commands, a token estimate, and a self-contained handoff prompt that another session or teammate can execute directly. ## Quick Start Ask the agent to run /li:plan on your approved design document to produce the plan, spec, and executor handoff for review and approval.
