What problem does it solve? When you want a concrete, actionable implementation plan before any code is written, this Skill enforces a planning-only mode: it inspects the repository read-only and produces a detailed markdown plan saved under .hermes/plans/, preventing premature or accidental changes to your project. ## Core Features & Use Cases - Plan-Only Mode: Guarantees no code edits, commits, or mutating commands during the turn; the only file written is the plan markdown. - Structured Plan Craft: Enforces a proven plan format with goal, architecture, exact file paths, complete copy-pasteable code, TDD steps, verification commands, and bite-sized 2-5 minute tasks. - Execution Handoff: Plans are designed to be executed task-by-task via subagent-driven-development with two-stage review. - Use Case: Before building a multi-step feature like user authentication, invoke plan mode to get a saved, timestamped markdown document listing every file to change, failing tests to write first, and exact commit commands. ## Quick Start Ask the agent to plan the implementation of your feature and save the plan to .hermes/plans/ without writing any code.
