What problem does it solve? Implementing a new feature across a monorepo requires coordinating exploration, planning, coding, validation, and quality gates, which is error-prone and token-expensive when done ad hoc. This Skill turns a free-text requirement into a structured multi-agent workflow with planned phases, paired executors and validators, and enforced quality gates. ## Core Features & Use Cases - Dynamic Phase Planning: Runs parallel Explorer and Planner agents, then validates the plan for ordering errors, parallel-safety, and scope creep before any code is written. - Scope-Based Execution: Chooses inline task spawning for small features, full agent teams for medium ones, and checkpointed teams for large ones, with per-phase executor and validator agents. - Quality Gates & Error Recovery: Runs type-check, lint, and build gates between phases with bounded retry loops, spot-check rules, and token budgeting to control cost. - Use Case: Ask to build a new comments feature in a packages/features directory; the Skill explores existing patterns, plans foundation through integration phases, spawns executor agents per phase, validates each output, and verifies final package exports with a full build. ## Quick Start Ask the agent to orchestrate the implementation of a new feature, for example: build a reactions feature in the features package using agents.
