A real deep agent

Plan → act → verify

Built on LangGraph + deepagentsjs. The Developer Agent decomposes work into a todo list, delegates to specialist subagents, then verifies before it calls anything done.

  • Decomposes every task into a visible plan

  • Delegates to architect, code-analyzer, tester

  • Checkpoints let you rewind any prior state

Safe by construction

Every shell command stops for approval

Every shell invocation and destructive write requires explicit approval through a permission modal that shows the exact command before it runs. Catastrophic patterns are denied outright across all three permission profiles.

  • Modal approval on every command
  • Sandboxed user scripts
  • Three permission profiles
