// how it works

How it works

  1. Clarify your goal

    Decide which coding harness you will run under Babysitter and how much human oversight (breakpoints) your workflow needs.

  2. Get the project

    Install the main Babysitter CLI globally from npm, and optionally the adapters CLI and runtime platform packages.

  3. Install and configure

    Install the plugin for your harness, then run the user and project setup commands to create your profile and configure project workflows.

  4. Run your first task

    Start an orchestration run in interactive, planning, autonomous, or continuous mode and monitor it with the built-in commands.

Why people love it

Process enforcement with quality gates

Workflows defined in code are enforced step by step; progression requires gates to pass and approvals at configured breakpoints.

Immutable decision journal

Every decision is recorded, giving an auditable trail for complex, long-running agent work.

Harness-agnostic adapters

The same processes run across 12 supported AI coding harnesses, avoiding lock-in to one vendor's agent tool.

Four run modes

Interactive mode pauses for approval, planning mode stops after design, autonomous (yolo) mode runs trusted tasks fully, and continuous mode runs indefinitely for monitoring-style work.

Internal headless harness

A built-in harness runs processes programmatically without any external coding agent, suiting CI/CD and scripted orchestration, and can delegate to discovered harnesses.

Run management tooling

Doctor diagnostics, a live observation dashboard, resume for interrupted runs, retrospectives, and cleanup of old runs.

// run it

Run it yourself

  1. Clone the project (optional)

    Most users install the published npm packages instead.

    git clone https://github.com/a5c-ai/babysitter.git
    cd babysitter
  2. Install the CLI and harness plugin

    Install the main CLI globally, then add the plugin for your harness, for example Claude Code.

    npm install -g @a5c-ai/babysitter
    claude plugin marketplace add a5c-ai/babysitter-claude
    claude plugin install --scope user babysitter@a5c.ai
  3. Run your first orchestrated task

    Inside your harness, invoke the babysit skill on a real task.

    claude "/babysitter:call implement user authentication with TDD"

Questions, answered

Who maintains it?

It is maintained by a5c-ai on GitHub.

Is it free to use?

Yes, Babysitter is MIT-licensed and free. The agents it orchestrates use your existing harness subscriptions or API keys.

Does it need a paid API key?

Babysitter itself needs no key; it drives harnesses such as Claude Code or Codex, which authenticate with your own accounts.

How does it compare to a well-known alternative?

Free-form agent chats improvise their process; Babysitter constrains agents to a coded workflow with gates, breakpoints, and a journal, trading flexibility for determinism and auditability.

How do I get started?

npm install -g @a5c-ai/babysitter, install your harness plugin, run the user and project setup commands, then start a run with /babysitter:call.
