systemprompt-agent 0.57.0

//! Repository layer for the agent crate.
//!
//! Each submodule owns persistence for a domain aggregate (tasks, contexts,
//! artifacts, agent services, execution steps). The aggregate
//! [`A2ARepositories`] bundles them for callers that need the full A2A surface,
//! together with the two cross-domain read seams the agent runtime depends on:
//! the managed-skill resolver and the MCP tool-execution lookup.
