types

types is the shared contract crate. It contains data structures and traits that must be visible across the workspace.

Responsibilities

• Agent, model, provider, skill, session, transcript, run, and sub-agent data types.
• Tool traits, tool errors, tool registry contracts, and toolset abstractions.
• Store traits for agents, sessions, secrets, and related services.
• Request/response contracts used by CLI, TUI, daemon, and runner.

Boundaries

• Do not put runtime side effects here.
• Keep implementation-specific helpers in the owning crate.
• Public cross-crate shapes belong here when more than one crate must agree on serialization or behavior.
