core/ — product API spine
English | 中文
The session log, system-prompt assembly, tool registry, agent vocabulary, deployment-default model selection, 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-default-model/ |
Default model selection shared by Agent entry points | ctx.agentDefaultModel |
agent-loop/ |
Default concrete agent driver | ctx.agentLoop |
scope supplies the shared scoping primitive. agent owns the public contract, while agent-loop is its default implementation; extension plugins depend on the seam so the driver remains swappable. agent-default-model owns the deployment selection an Agent entry point uses only when a session has no selection of its own.
Runnable compositions belong to examples/agent-spine-demo; this group owns only the swappable spine pieces.
The subsystem reference — the package-by-package loop map, the Agent handle and its delivery/interception contracts — is docs/subsystems/core.md; the default runnable composition is examples/agent-spine-demo.
