Six GitHub repos for building an agent harness around GPT-6 Astra
The author argues GPT-6 Astra is only the brain and lists LangGraph, smolagents, Composio, MCP Servers, E2B and AgentOps as repos that give the model tools, sandboxes and execution tracing.
GPT-6 Astra is getting f…cking illegal but the model is only the brain 6 GitHub repos for building the harness around it 01 LangGraph ▸ https://github.com/langchain-ai/langgraph → long-running stateful agents 02 smolagents ▸ https://github.com/huggingface/smolagents → agents that think in code GIVE IT HANDS 03 Composio ▸ https://github.com/ComposioHQ/composio → 1,000+ toolkits for agents 04 MCP Servers ▸ https://github.com/modelcontextprotocol/servers → tools + data through one protocol LET IT EXECUTE 05 E2B ▸ https://github.com/e2b-dev/E2B → isolated sandboxes for agent code 06 AgentOps ▸ https://github.com/AgentOps-AI/agentops → trace failures + cost + agent runs the harness: GPT-6 Astra → plan → choose tools → execute → inspect → recover → continue that’s the part people keep missing a smarter model gives you better reasoning a better harness lets that reasoning survive the real world ⭣
