aco-system: An Entire Company OS for Claude That Writes User Stories, Breaks Tasks, Reviews PRs

Someone posted on r/ClaudeAI about aco-system, an open-source framework that turns a single GitHub issue into a complete, reviewed pull request — all driven by Claude without manual intervention. The post describes the workflow:
The user typed into Claude: "Add Stripe payments with webhook support. Use aco-system." From there, the system autonomously:
- Wrote the user story
- Broke it into 8 tasks with estimates
- Validated the plan (checking for secrets, missing criteria, bad config) — would have stopped if validation failed
- Wrote the code once validation passed
- Created a branch and opened a PR with a meaningful description
- Reviewed the PR, added comments, flagged tests
The user only had to approve the final PR. The experience was described as "less like running a tool and more like having a junior team that doesn't sleep and doesn't need standup."
The project is available at github.com/aniketkarne/aco-system.
