I built BHive: a multi-agent framework for Gemini/OpenAI/Anthropic/Ollama. Tear it apart.

#showdev #opensource #typescript #llm

I've been building this for two weeks and want honest technical feedback before I invest more time.

What it does

Bhive is a multi-agent framework in TypeScript. Agents ("Bees") can delegate tasks to each other, call tools, and it works with any LLM provider — Gemini, OpenAI, Anthropic, or local Ollama — through the same code.

Architecture decisions I'm unsure about

  • Provider abstraction via an LLMAdapter interface, with a ToolCallingParser that normalizes tool-call formats across providers. Good pattern, or overengineered for what it does?
  • Tool-call validation happens in the Bee's execution loop (not inside each adapter). Right layer for that?
  • Timeout resolution has three levels (explicit arg → env var → default). Reasonable, or too much configuration surface?

What I'd love feedback on

  • The security model (ToolCallValidator: injection guards, allowlists, size limits) — anything missing?
  • Whether the delegation pattern (Bee → Bee, via createDelegationTool) makes sense as an abstraction
  • Anything that smells wrong in the repo structure

Tests: 299 passing, ~98% coverage. But test coverage isn't the same as "this is well-designed" — that's what I actually want checked.
