lean-harness

Run the full LeanHarness feature workflow for an existing codebase: specify, discover, plan, build, and check. Use when the user invokes /lh-do with a feature request or asks Claude Code to complete a feature through LeanHarness.

Execute LeanHarness feature tasks with bounded context, boundary discipline, tests, compact summaries, and verification evidence. Use when the user invokes /lh-build or wants Claude Code to implement planned tasks.

Verify a LeanHarness feature against acceptance criteria, changed files, risk gates, review findings, and command evidence. Use when the user invokes /lh-check or wants a final pass, needs-fix, or blocked verdict.

Perform LeanHarness on-demand discovery for an existing codebase and produce a focused change boundary. Use when the user invokes /lh-discover or needs relevant files, tests, commands, constraints, risks, and unknowns before planning.

Create a LeanHarness implementation plan and task list from an existing feature spec, discovery report, and change boundary. Use when the user invokes /lh-plan or needs planned tasks before building.

Create or update a LeanHarness feature specification from a user request. Use when the user invokes /lh-spec or wants to define goal, non-goals, acceptance criteria, constraints, assumptions, and verification expectations before implementation.

Inspect LeanHarness feature state and summarize current specs, discovery, plans, tasks, checks, blockers, and next actions. Use when the user invokes /lh-status or asks what is happening in the current LeanHarness work.
