What problem does it solve? Jumping straight into coding a multi-step feature often leads to missed requirements, vague tasks, and rework. This Skill produces a detailed, self-contained implementation plan saved to .hermes/plans/ so that any implementer (human or subagent) can execute it without guessing. ## Core Features & Use Cases - Plan-only mode: Inspects the repository with read-only commands and writes a markdown plan without modifying project code or running mutating commands. - Structured task breakdown: Splits work into 2-5 minute tasks with exact file paths, complete copy-pasteable code, exact test commands with expected output, and commit steps following TDD, DRY, and YAGNI principles. - Execution handoff: Saves the plan under .hermes/plans/ with a timestamped filename and offers to execute it via subagent-driven-development with two-stage review. - Use Case: You describe a new authentication feature; the Skill explores the codebase, then saves a plan with sequential tasks covering the User model, password hashing utility, failing tests, verification commands, and commit messages. ## Quick Start Ask the agent to plan the implementation of your feature, for example: plan adding password reset functionality to the user service.
