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.log and results.json outside 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.

•templates/harness_plan.json: Plan scaffold for long-running runs.

Validation

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