llama-cpp-agent vs cap-evolve

llama-cpp-agent: llama-cpp-agent is a Python framework for interacting with LLMs running via llama.cpp. It provides a unified interface for chat, structured function calls, and JSON-formatted output — including models not explicitly fine-tuned for function calling. Developers can define tools and callable functions that the agent invokes directly, making it practical for building local agentic workflows without cloud dependencies.; cap-evolve: cap-evolve is an honesty-guaranteed framework that optimizes AI agent capabilities like prompts, tools, and skills by learning from failed evaluation traces. It automates the loop of evaluation, diagnosis, candidate generation, and validation, ensuring improvements are significant and honest.
