nerve vs capa

nerve: Nerve is an Agent Development Kit (ADK) that allows technical users to build, run, evaluate, and orchestrate LLM-based agents using declarative YAML configurations and a command-line interface. It emphasizes programmable, auditable, and reproducible automation with support for multi-agent communication and various LLMs.; capa: CAPA is a package manager designed for AI coding agents, allowing developers to declare skills, tools, and rules in a single `capabilities.yaml` file. It then automatically deploys these configurations to over 35 different AI agent platforms, ensuring consistent and optimized setups.

Features

nerve logonerve
01Declarative Agents: Define agents using a clean YAML format including system prompt, task, tools, and variables.
02Built-in Tools & Extensibility: Utilize shell commands, Python functions, or remote tools, all fully typed and annotated.
03Native MCP Support (Client & Server): The first framework to define MCP servers in YAML, acting as both client and server for deep orchestration.
04Evaluation Mode: Benchmark agents with YAML, Parquet, or folder-based test cases for reproducible tests, structured outputs, and progress tracking.
05Workflows: Compose agents into simple, linear pipelines to create multi-step automations with shared context.
capa logocapa
01Centralized `capabilities.yaml` for managing agent content across 35+ AI agents.
02Automated deployment of rules, hooks, and tools into the native formats required by various agents.
03Optimized inference leading to 19-40% cheaper costs, achieved through lazy-loading and per-agent MCP servers.
04Granular tool access for sub-agents with filtered MCP endpoints, ensuring they only see necessary tools.
05Version-controlled configurations via `capabilities.lock`, ensuring reproducible setups across development environments.
