About open-agent-spec

prime-vector/open-agent-spec

Open Agent Spec is a declarative YAML standard and CLI for defining and generating AI agents. One spec, any LLM engine (OpenAI, Anthropic, Grok, Cortex, local, custom).

Enforces strict input/output schema validation to prevent silent failures when LLM responses deviate from expected structure, and supports both direct execution via `oa run` and Python scaffold generation via `oa init` for gradual customization. Uses Jinja2 templating for dynamic prompts and provides a CLI-first workflow that keeps agent definitions versioned in `.agents/` directories for CI/CD integration and multi-engine portability.
