The Smallest Useful Model Call

Part 2 — Get the Model Out of the Chat Box

The smallest working call

CodeAI’s OpenCode cognition adapter, invoked directly without the recorded-call runtime, does the minimum well. One CallSpec becomes one user message, the message goes out as an ordinary HTTP request, and a CallResult comes back:

adapter = OpenCodeCognitionAdapter(model="mimo-v2.5", protocol="chat_completions")
result = adapter.invoke(spec)  # one CallSpec in, one CallResult back
if result.status != "succeeded":
    raise RuntimeError(result.error)
review = result.raw_output

It keeps failure in its own channel instead of passing a diagnostic off as a review. It returns the usage with its source label alongside the convenient string. Those two habits already put it ahead of a great deal of production code.
