CAPA

CAPA simplifies the management of agent capabilities through a command-line interface. Key features include: • Centralized capability definitions in `capabilities.yaml` • Streamlined tool and skill orchestration • Reproducible setup for agent environments • Dynamic loading of capabilities based on task This open-source package manager allows developers to abstract away the complexity of wiring tools, skills, and MCP servers. Instead of manual configuration, all definitions reside in a single file, promoting cleaner orchestration and reducing context bloat for agents. It functions similarly to how `npm` manages packages for software projects, but specifically tailored for agent capabilities. CAPA addresses common challenges like an abundance of tools, duplicated skills, and static configurations. It enables the creation of single servers that expose only the necessary tools for specific skills, eliminating manual overload. Skills can be reused across projects by referencing them from source control (GitHub, GitLab) or local repositories, with `capa install` handling automatic fetching. Complex CLI commands are simplified through variable substitution and automated setup, converting intricate operations into straightforward tool calls that optimize resource usage. Designed for developers and engineering teams building sophisticated agents, CAPA facilitates self-improving agents by allowing them to edit their own `capabilities.yaml` file, creating an evolutionary feedback loop. It also incorporates security features to block dangerous phrases and sanitize skill content, ensuring safe and controlled agent operations through configurable character sets and blocked phrase lists.
