"defineTool compiles an object root, so the annotation is a bare TypedDict class name that opens nothing" is a false universal: parameterSchemaSpecToJsonSchema compiles an OPEN object root, so an empty parameter table and one with unrepresentable field names both degrade to dict[str, Any], which opens one bracket. The conclusion the sentence carries is unaffected -- 1 or 2 against a 182 cap -- so say "a bare TypedDict class name or dict[str, Any], neither of which carries a chain", in the JSDoc and the test comment that copied it. pyScalar's docstring said the subscript tool-name comment quotes "through the same call". It quotes through its own JSON.stringify call site in renderToolsSdkPy and never reaches pyScalar, which only takes const/enum scalars. Same function, different call site. The mode-'both' test attributed assembly.tools to the public schemas(). That projection is wireSchemas, wired at ctx.systemPrompt.tools.
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.
