Building Specialist LLM Agents: Technical, Risk, Cost, and Timeline Analysis

The first post covered why I split document analysis into multiple agents. This one covers how the specialists are actually built. The Python code is not the hard part. The specialist behavior mostly comes from: the system prompt the output schema the boundaries around what the agent should ignore The code is intentionally repetitive. Once you’ve written a couple agents, it’s a breeze. The shared base class Every agent needs the same basic execution logic: ...

That’s easy. The interesting part is how much the output changes when the model is forced to analyze the same document through different lenses before producing a final answer. ...
