need feedback on a coding agent platform build for startups!

Hi guys,

I am a software engineer and a solo founder, the biggest blocker for me was lack of engineering resources for delivering quickly, I was using github copilot and cursor before, but as my team grew to 5 members, everything became messy, people were using their own versions of prompts to get the work done, and the agent was working in local, so while the agent was making changes we need to sit and watch it. even we tried to use background agents, but it became difficult to review so many changes when the agent was finished doing the task. also in cursor background agents, we cannot have multiple repositories in a workspace. we need something in between local and entirely remote execution of task. so we created an agent platform for our team.

  1. we solved the problem of people using different versions of prompts and env variables etc. by enabling devs to create the workspaces wherein you can set prompts, skills, .md once and make it shareable across the groups, we ensured that no one used a different environment for giving tasks to the agent.
  2. even though our tasks are executing in secure VMs but the dev can always pitch in to see what AI is doing in our in-browser IDE. so if agent goes away from the line it can be brought back. our local project was free now, we could now work in two fronts, give long running tasks and work on important things locally (we also created our own CLI agent)
  3. the most complicated problem was how to review such big changes once the cloud job is completed. we decided, to let agent debug its own code, by giving it browser, computer use, background processes, such that the agent can perform unit, functional, and regression testing. and the main thing was that now the agent could work on multiple repositories at once, this feature i did not find anywhere.

we have also tried devin ai, i was amazed when i found that we cannot share resources like machine configurations, system prompts, and secrets, but it do asks you to create an organization! what is the whole point of inviting members when you cannot share with them anything? that's why we created our own agent.

For engineering founders, i need feedback if this workflow can help them as well. you can check our work ( phantomx dev is the name of our platform) thanks!
