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.</p> <h2> Architecture decisions I'm unsure about </h2> <ul> <li>Provider abstraction via an <code>LLMAdapter</code> interface, with a <code>ToolCallingParser</code> that normalizes tool-call formats across providers. Good pattern, or overengineered for what it does?</li> <li>Tool-call validation happens in the Bee's execution loop (not inside each adapter). Right layer for that?</li> <li>Timeout resolution has three levels (explicit arg → env var → default). Reasonable, or too much configuration surface?</li> </ul> <h2> What I'd love feedback on </h2> <ul> <li>The security model (<code>ToolCallValidator</code>: injection guards, allowlists, size limits) — anything missing?</li> <li>Whether the delegation pattern (Bee → Bee, via <code>createDelegationTool</code>) makes sense as an abstraction</li> <li>Anything that smells wrong in the repo structure</li> </ul> <p>Repo: <a href="https://github.com/dcooperdev/bhive-core" rel="noopener noreferrer">https://github.com/dcooperdev/bhive-core</a></p> <p>Tests: 299 passing, ~98% coverage. But test coverage isn't the same as "this is well-designed" — that's what I actually want checked.</p> showdev opensource typescript llm
