description: Klu (klu.ai) is an LLM app platform for designing, deploying, evaluating,
  and observing prompt-driven AI applications. The Klu Engine exposes a REST API at
  https://api.klu.ai/v1 (Bearer API key) where an Action encapsulates a prompt template,
  model config, context (RAG), and output parsing, and is invoked to generate completions,
  with data, feedback, sessions, and models managed alongside it. NOTE - product
  development appears dormant - the official klu SDK last shipped in March 2025 and
  the founding team's recent open-source work has shifted toward xAI / Grok tooling
  - see review.yml for the honest status assessment.

    completion plus a feedback URL. Supports streaming, async execution, response
    caching, session memory, context metadata filtering, and experiments. This is
    the core generative endpoint of the Klu Engine.
