The adapter omits the seam's reasoning field whenever a model carries no reasoning metadata, which is the model's own property and says nothing about where the model came from. Both the JSDoc and the Agent Note read as though only hand-declared models were meant, so a reader would infer that the 251 installed-catalog models pi-ai marks as non-reasoning still offer their single off level. They do not, and that is the point: a picker holding only off misrepresents a provider that thinks by default, because off dispatches the same bytes as naming no effort at all. Behavior is unchanged; only the prose that describes it was narrower than the contract. adapter.spec.ts already pins the catalog case through openai/gpt-4.1 and catalog.spec.ts pins the hand-declared one.
llm/ — LLM capability family
English | 中文
The LLM seam and its provider adapters. The interface package (llm) owns the abstract service, the content-block vocabulary, and the stream-chunk assembler; the adapters are concrete implementations that register on ctx.llm. All product packages.
| Package | Role | ctx key |
|---|---|---|
llm/ |
LLM service and shared streaming vocabulary | ctx.llm |
token-meter/ |
Replay-aware token measurement | ctx.tokenMeter |
llm-retry/ |
Provider-scoped retry policy | listens to agent/request-error |
llm-deepseek/ |
Direct DeepSeek adapter | registers on ctx.llm |
llm-pi-ai/ |
Multi-provider pi-ai adapter | registers on ctx.llm |
Adapters register provider routes on the seam; retry and token measurement remain separate consumers. The child READMEs own routing, metadata, replay, and provider-wire details; the LLM architecture decisions own the rationale.
