llm/ — LLM capability family

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/ Abstract LLM service + content-block vocabulary + chunk assembler ctx.llm
llm-deepseek/ DeepSeek API adapter (hand-rolled fetch/SSE) (registers on ctx.llm)
llm-pi-ai/ DeepSeek adapter via @earendil-works/pi-ai (design twin) (registers on ctx.llm)

The interface lives at llm/llm/; adapters are flat siblings under the group. A new provider adapter joins here and registers on ctx.llm without touching the interface. See twin LLM adapters for why two adapters exist.
