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

1. Fill templates/harness_plan.json.
2. Write progress.log and results.json outside the skill directory.
3. 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.

Resources

• references/harness-checklist.md: Resumability and handoff checklist.
• templates/harness_plan.json: Plan scaffold for long-running runs.

Validation

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