Seven open-source repos build a coding system around GPT-6 Astra
The list covers OpenHands, Serena, Context7, GitHub MCP, E2B, pytest, and Langfuse, leaving Astra to handle only reasoning and decisions.
GPT 6 Astra + GitHub is getting really dangerous… 7 open source repos are enough to build a serious coding system around it 01 OpenHands ▸ https://github.com/OpenHands/OpenHands → gives Astra an environment for editing code, running commands and working through real engineering tasks 02 Serena ▸ https://github.com/oraios/serena → understands symbols, references and repo structure before the model starts changing files 03 Context7 ▸ https://github.com/upstash/context7 → pulls current docs and examples when the task depends on external libraries 04 GitHub MCP Server ▸ https://github.com/github/github-mcp-server → gives the agent direct access to issues, repos and GitHub actions 05 E2B ▸ https://github.com/e2b-dev/E2B → runs generated code and commands inside an isolated environment 06 pytest ▸ https://github.com/pytest-dev/pytest → turns the existing test suite into a hard gate before completion 07 Langfuse ▸ https://github.com/langfuse/langfuse → shows exactly what the model saw, called and broke during the run what I’d actually give each layer repo understanding → Serena current docs → Context7 engineering workspace → OpenHands GitHub access → GitHub MCP runtime → E2B verification → pytest debugging the agent itself → Langfuse GPT 6 Astra sits above all of it and handles the decisions that actually need reasoning That is a much better use of a frontier model than making it waste context rediscovering files, reading stale docs and guessing why its own code failed
