02Who is this for

## One set of docs, two ways to read them

Product & operations

No code required. Step-by-step guides for designing agents, managing prompts, reviewing runs, and approving outputs — with the deep technical bits tucked behind “Technical details” until you actually need them.

Engineers

SDKs for Python, JavaScript, and Go, a CLI, an MCP server, agent triggers, and a full REST API — everything you need to wire PromptRails into production systems.
