Claude Code clone

The flagship coding agent: Sonnet plans and writes, Haiku does the grepping and reading, agent_spawn stitches them together. The architecture is documented end-to-end in the blog post linked below.

Install it locally

# save the YAML below as app.yaml in a new folder
digitorn install ./claude-code-clone

This is a local install: the folder you create is the source. No Hub package to publish first.

What you get

Coordinator that plans first, then executes
Explorer worker for grep/glob/read at Haiku rates
security.behavior.profile: coding for sane runaway protection
Real sub-agent dispatch via the agent_spawn module

How it works

two agents, two brains

Coordinator runs on claude-sonnet-5 for the writing-and-deciding work. Explorer runs on claude-haiku-4-5 for the grep-and-summarise work. Each agent lists only the modules it actually needs.

agent_spawn, granted with its real tool name

The coordinator's modules list grants {agent_spawn: [agent]} - agent is the actual tool name the runtime registers, not a made-up one. Calling it dispatches the explorer and waits for its result.

security.behavior for runaway protection

security.behavior.profile: coding lives under the top-level security: block (not a bare behavior: key) and ships sane defaults for a coding agent - the same profile Digitorn's own coding agents run in production.
