What problem does it solve? When a task needs careful thought before any code changes, this Skill enforces a plan-only mode: it produces a concrete, actionable markdown implementation plan saved to the workspace instead of prematurely editing files or running mutating commands. ## Core Features & Use Cases - Plan-only enforcement: Blocks code edits, commits, and mutating terminal commands while allowing read-only repo inspection. - Structured plan authoring: Guides creation of plans with goal, architecture, bite-sized TDD tasks (2-5 minutes each), exact file paths, complete code snippets, and verification commands. - Workspace-aware saving: Stores plans under .hermes/plans/YYYY-MM-DD_HHMMSS-<slug>.md, compatible with local, docker, ssh, modal, and daytona backends. - Use Case: Before implementing a multi-step feature, invoke plan mode to produce a task-by-task implementation plan with failing-test-first steps and commit points, then hand it off to subagent-driven-development for execution. ## Quick Start Ask the agent to plan the implementation of your feature and save the plan to .hermes/plans/ without making any code changes.
