core/ — product API spine

English | 中文

The session log, system-prompt assembly, tool registry, agent vocabulary, and concrete loop that form the harness's default control spine. These are product packages — the stable surface plugins and consumers build against.

Package Role ctx key
scope/ Scoped-context registration primitive library — no ctx key
session/ Event-sourced session log and in-memory store ctx.sessions
system-prompt/ Prompt and tool-schema assembly registry ctx.systemPrompt
tools/ Scoped tool registry and execution pipeline ctx.tools
agent/ Agent interface, registry, and event vocabulary ctx.agents
agent-loop/ Default concrete agent driver ctx.agentLoop

scope supplies the shared scoping primitive. agent owns the public seam, while agent-loop is its default implementation; extension plugins depend on the seam so the driver remains swappable.

Runnable compositions belong to examples/agent-spine-demo; this group owns only the swappable spine pieces.
