WorkHarness

WorkHarness is a workflow harness that helps AI coding agents handle large tasks in stages.

The workflow is:

clarify -> context-gather -> plan -> generate -> evaluate

Each run's state and artifacts are stored under .workharness/runs/<run-id>/, and automatic workflows can continue through Codex or Claude Stop hooks.

Supported Agents

• Claude Code
• Codex CLI

When using Codex CLI, Codex may ask you to approve project hook execution. To keep WorkHarness workflows moving correctly, make sure to approve the Stop hook in Codex. If you do not approve it, the workflow will not continue after certain stages. For details, see the official Codex hooks documentation.

Install

Run WorkHarness from the directory where you want to install it.

npm create workharness@latest
pnpm create workharness@latest
yarn create workharness@latest

The installer checks that the current directory is inside a git repository and that python3 is available. In a monorepo, run the create command from the package or app directory that WorkHarness should manage. It then asks which agent integrations to enable.

[x] Codex
[ ] Claude

To install without prompts:

npm create workharness@latest -- --agents codex,claude
pnpm create workharness@latest --agents codex,claude
yarn create workharness@latest --agents codex,claude

Agent Integrations

Agent selections are stored in:

.workharness/install.json

The selected agents create the required hooks and skill directories.

• Codex: .codex/config.toml, .codex/hooks.json, .codex/skills
• Claude: .claude/settings.json, .claude/skills

.workharness/skills is the source of truth. Codex/Claude skill directories are generated output copied from this source. Symlinks are not used. After editing .workharness/skills, run sync explicitly to reflect those changes in Codex/Claude skills.

Commands

Purpose	npm	pnpm	Description
Add Agent	npm run workharness:add-agent	pnpm run workharness:add-agent	Choose supported agents from a checkbox prompt.
Add Agent Directly	npm exec workharness -- add agent claude	pnpm exec workharness add agent claude	Add a specific agent directly. Currently supports codex and claude.
Sync Skills	npm run workharness:sync	pnpm run workharness:sync	Reflect .workharness/skills source into Codex/Claude generated skills.
Check Status	npm run workharness:doctor	pnpm run workharness:doctor	Check install state and agent skill targets.
Dashboard	npm run workharness:dashboard	pnpm run workharness:dashboard	Open the dashboard on the default port 4673.
Dashboard With Port	npm exec workharness -- dashboard -p 6006	pnpm exec workharness dashboard -p 6006	Open the dashboard on a specific port.
Update	npx workharness@latest upgrade	pnpm dlx workharness@latest upgrade	Update .workharness to the latest package payload.

Before replacing .workharness/skills, upgrade backs up the current skill source to .workharness/backups/skills-<timestamp>/. WorkHarness-managed files that no longer exist in the new package payload are removed.

sync does not download or replace the core .workharness payload. It overwrites enabled agent hooks and generated skill copies from the installed .workharness/skills source.

For yarn projects, run the same script names with yarn.

yarn workharness:add-agent
yarn workharness:dashboard
yarn workharness:sync
yarn workharness:doctor

Quick Start

Ask the agent:

Use `workharness` to implement <task>.

Before starting, choose:

• loop count: maximum number of generate -> evaluate retries when evaluate fails
• commit mode: none, phase, final

Defaults:

loop count: 2
commit mode: none

Dashboard

By default, the dashboard first tries http://127.0.0.1:4673/ and falls back to an available port if 4673 is busy.

The dashboard shows the current active run, stage progress, artifacts, diagnostics, and run history.

Project Guidance

If your project has architecture docs, coding rules, or review criteria, copy the example context file:

cp .workharness/context.example.json .workharness/context.json

Then edit .workharness/context.json.

• context-gather.documents: documents to reference before planning
• context-gather.skills: agent skills to consult for task-relevant conventions
• evaluate.documents: documents to reference during review
• evaluate.skills: agent skills to consult as review criteria
• evaluate.rules: additional review rules
