Example: Local Query

$ certainlogic-coder local "python list comprehension"
[
  {
    "question": "python list comprehension",

    "source": "python_docs"
  }
]

Example: Brain API Query

$ certainlogic-coder api "rate limiting fastapi"
{
  "method": "cache",
  "answer": "Use SlowAPI or FastAPI‑limiter. Example: from slowapi import Limiter, _rate_limit_exceeded_handler",
