The notebook for API workflows should live where the code lives.
Reqbook is a local-first API workflow notebook for teams that want API docs, requests, tests, flows, and coding-agent context to be readable in pull requests, executable in CI, and visible in a local browser UI.
Why it exists
Coding agents can read source files, but they still waste context rediscovering routes, request bodies, environment variables, and expected responses. Reqbook gives them a stable contract in api-docs/.
What it is
A single Rust binary with a CLI, local web UI, Markdown endpoint notebooks, flows, importers, validation, and agent skills for Claude Code, Cursor, Copilot, Codex, Antigravity, Windsurf, and OpenCode.
What it is not
It is not a hosted API workspace or a proprietary collection format. The source of truth is ordinary markdown committed beside your application code.
