- llm-retry: validate config before registering the projection unit; document the branded-retry-id zod cast; start stateVersion at 1. - agent-loop: register turnBoundary only after every config validation, so a rejected constructor leaves no unit behind; the defensive-cap test no longer needs fiber cleanup. - agent-instructions: keep newest-first per-scope change history so the latest visible change survives a surface replacement shadowing the newest one (restores the previous scan-visible semantics); add a regression test for the delete-after-shadow sequence. - tool-skill: keep catalog-message history so a shadowed newest catalog message still falls back to the latest visible digest. - session-query-sqlite: drop the unused required sessionProjections injection. - plan-mode: restore the command/done error-drop regression test and the cold-replay command/done fold; drop the inaccurate state-reference comment. - tool-todo: remove a stray blank line; document the turnBoundary reader contract on the projection type.
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.
