What is Babysitter?
Babysitter enforces obedience to agentic workforces, enabling them to manage extremely complex tasks and workflows through deterministic, hallucination-free self-orchestration. Define your workflow in code - Babysitter enforces every step, ensures quality gates pass before progression, requires human approval at breakpoints, and records every decision in an immutable journal. Your agents do exactly what the process permits, nothing more.

Internal Harness (No AI Coding Agent Required)
Babysitter ships with a built-in internal harness that runs processes programmatically without any external AI coding agent. This is useful for CI/CD pipelines, scripts, automated testing, and headless orchestration:
npm install -g @a5c-ai/babysitter-sdk
# Run a process definition using the internal harness
babysitter harness:call --harness internal --process .a5c/processes/my-process.js#process --workspace .
# Or run a free-form prompt
babysitter harness:call --harness internal --prompt "run lint and tests" --workspace .
The internal harness uses the SDK's built-in Pi execution engine directly. It supports all capabilities (Programmatic, SessionBinding, StopHook, HeadlessPrompt) and requires no external CLI.
