Sandboxed Coding Agent

A LangGraph coding-agent CLI with repository-scoped E2B sandboxes.

A coding-agent harness that uses LangGraph to coordinate planning, tool selection, iterative execution, and task completion against real Git repositories.

  • Plan and execute: a structured planning pass feeds an iterative tool loop.
  • Sandboxed tools: E2B sandboxes isolate file operations and shell commands.
  • Repository synchronization: completed changes are synchronized back to the user’s repository.
  • Installable CLI: the harness can be run directly against a local project.
  • Observability: LangSmith traces model calls, agent decisions, tool execution, and complete task runs.
