Where people and agents ship software together. The open-source git platform for the whole job: issues, agents, checks and deploys to the edge.

1//! Scopes: what an access token may do on its owner's behalf.
2//!
3//! A personal access token, a workspace's token and an application signed
4//! in with OAuth each carry a set of scopes. A token reaches whatever the
5//! one it acts as can reach: a person's token, that person's workspaces and
6//! repositories; a workspace's token, that workspace. What a request may do
7//! is the intersection of two things: the role of whoever the token acts as
8//! (see [`crate::access`]) and the token's scopes.
9//!
10//! Each scope is a resource and a level, written `resource:level`, such as
11//! `issues:write`. A higher level of a resource includes the lower ones:
12//! `repo:admin` includes `repo:write`, which includes `repo:create`, which
13//! includes `repo:read`.
14//!
15//! This module is the one source of truth: the API (REST and MCP) and git
16//! enforce it, and identity stores it. `packages/contracts/src/scopes.ts`
17//! mirrors the table for the site; a test keeps the two the same.
