What problem does it solve? It prevents vague or incomplete implementation guidance by producing a detailed, step-by-step markdown plan before any code is written, so implementation becomes obvious even for someone with zero codebase context. ## Core Features & Use Cases - Plan-Only Mode: Inspects the repository with read-only commands and writes a plan without editing project files, committing, or running mutating commands. - Structured Task Breakdown: Splits work into 2-5 minute tasks with exact file paths, complete copy-pasteable code, exact commands with expected output, and TDD verification steps. - Timestamped Plan Storage: Saves plans under .hermes/plans/ with a YYYY-MM-DD_HHMMSS-slug filename, then offers handoff to subagent-driven-development for execution. - Use Case: Before building a multi-step feature like user authentication, invoke plan mode to get a sequenced task list covering models, hashing utilities, tests, and commits that a subagent can execute task-by-task. ## Quick Start Ask the agent to plan the implementation of your feature, for example: create a plan for adding user authentication with tests, and it will save a detailed markdown plan under .hermes/plans/.
