Long Running Harness Kit
Overview
Define a minimal harness that can pause and resume safely, with clear artifacts that survive context resets. Emphasize initializer + coder roles and persistent run state.
Quick start
- Fill
templates/harness_plan.json. - Write
progress.logandresults.jsonoutside the skill directory. - Use the initializer to set up context; use the coder to make incremental progress.
Core Guidance
- Use two roles: initializer (setup + context) and coder (incremental tasks).
- Persist state each step (progress, decisions, artifacts).
- Keep tasks small; checkpoint after every meaningful change.
- On resume, read artifacts first, then continue with a narrow next step.

Validation
- Confirm artifacts exist and a resume step can continue from the last checkpoint.
