Agent registry
Every agent is a versioned object: prompt, model, tools, budget and guardrails. Fork it, diff it, roll it back.
AnthropicSub is the agent manager for Anthropic models. Spin up agents, give them tools, route work between them, and watch every token, run and decision in real time.

The product
Every agent is a versioned object: prompt, model, tools, budget and guardrails. Fork it, diff it, roll it back.
Chain agents into graphs with fan-out, retries and human checkpoints. No glue scripts to babysit.
Attach MCP servers, HTTP tools or your own functions once, then share them across the whole fleet.
Watch reasoning, tool calls and token spend stream in as they happen. Stop a run mid-flight.
Hard spend caps, allowed-tool lists and approval gates on anything that writes, pays or sends.
Ship a prompt edit only when it beats the current agent on your own test set.
Live orchestration
One console for the whole fleet: status, queue depth, spend and the full reasoning trace of any run. Pause, redirect or kill an agent without redeploying anything.
