Crate zeph_agent_context 

Agent context-assembly service for Zeph.

This crate provides service::ContextService — a stateless façade for all context-assembly operations that were previously implemented directly on Agent<C> in zeph-core. Extracting this logic means that editing context-assembly code does not trigger recompilation of the tool dispatcher (zeph-agent-tools) or the persistence layer (zeph-agent-persistence).

Architecture

zeph-agent-context depends on zeph-memory, zeph-llm, zeph-context, zeph-config, zeph-common, zeph-skills, and zeph-sanitizer. It does not depend on zeph-core — this is the core invariant that keeps context-assembly changes from triggering full workspace rebuilds.

zeph-core depends on this crate and constructs narrow borrow-lens views (state::MessageWindowView, state::ContextAssemblyView, state::ContextSummarizationView) from Agent<C> field projections, then delegates to ContextService.

Features

• self-check — gates retrieved-memory mirror types for the MARCH self-check pipeline.
• index — enables zeph-index integration via the IndexAccess trait.
