Overview
A skill and plugin set that adds a plan, work, review, sync and release workflow to coding assistants. It keeps the spec and tasks in spec.md and Plans.md, runs checks, and requests a review separate from the implementation. A Go-native guardrail engine blocks operations such as secret reads, production deploys and forced pushes to main.
Who it is for: Developers using Claude Code, Codex or Cursor who want plan and review gates
Strengths
- Plan and task state lives in spec.md and Plans.md inside the project
- Supported install paths for Claude Code, Codex CLI, Cursor and Grok
- Guardrail engine is bundled Go binaries, no Node.js needed at runtime
- Resumable work via /harness-work --resume latest
Weaknesses
- Guardrails do not guarantee containment; coverage differs per tool
- Cursor has no filesystem isolation; restrictions are applied only by Harness
- Codex child agents can inherit parent permissions
- More workers, reviews and retries raise costs on your model provider
What it needs
- no GPU
- Needs Claude Code v2.1+, Codex CLI, Cursor or Grok, Git, Go 1.26.0+ (only to build from source)
- Models: Claude Code, Codex CLI, Cursor, Grok
