`SDK_RENDERERS` and `RUN_CODE_FLAVORS` had to stay in step by review alone: the `Object.hasOwn` guards catch drift only once a runtime reporting the half-added language exists, which is the one case that cannot arise. Both tables are now `satisfies`-checked against a shared `CodeSdkLanguage` union, so a missing or extra entry fails `typecheck`. The declared `Record<string, …>` type stays, since `CodeRuntime.language` is an unconstrained `string`. The code-runtime seam's own README row and `CodeRuntime.language` JSDoc still named `'typescript'` as the sole well-known value; both now name `'python'` too and say only `'typescript'` has a published backend.
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.
