Pick any line to see why it is the way it is: the commit, the pull request and issue it came from, and what the agent was thinking.

Thirteen MCP tools and classic token scopes; agents rate their confidence and can be put on an issue in one step1//! The MCP server's tools: a few resource tools, each with an `action`.
2//!
3//! Every operation is one action of one tool. A call is dispatched to the
4//! operation it names, so permissions, the audit log, billing and outcomes
5//! are exactly those of the REST API. A token sees only the actions its
6//! scopes allow, and a tool none of whose actions it may use is not listed.
7//!
8//! The listed input schema is one flat object: `action`, then every field
9//! any of its actions takes. Which fields each action needs is in the
10//! `action` field's description and checked on every call. Claude's API,
11//! and so most MCP clients, refuse a tool whose input schema has `oneOf`
12//! at its top level, so the schema keyed by action, with each action's
13//! required fields, is [`discriminated`], published on the server's card
14//! and in the docs.
