AI Analysis

●●SolidShip ItBig Brain

E2B sandbox isolation prevents agent chaos while streaming realtime previews before PR creation.

Strengths
  • •Per-session E2B VMs provide genuine isolation preventing agent-induced repository corruption.
  • •Realtime streaming of agent reasoning and tool calls offers unprecedented debugging visibility.
  • •Automatic preview environment deployment validates code changes before committing to branches.
Weaknesses
  • •Requires managing three separate API keys (GitHub, Anthropic, E2B) creating operational friction.
  • •Headless opencode limits agent capabilities compared to full IDE-based coding assistants.

Post Description

Hey all,

I've been quietly working on a background agent runner inspired by Ramp Inspect.

I'm working on closing the loop between prompting, testing, and deploying:

1) You prompt agents to make changes to your projects in a web interface

2) Agents pull your code and make changes in a sandbox

3) Instantly test your changes with preview environments

4) Get a PR back

Every star on GH is motivation to keep going. Appreciate any comments or input!
