Four review findings across the seam and both adapters. registerAdapter now returns a handle carrying replace(providers): the candidate route set is validated in full before anything moves, so a route another adapter owns leaves the previous registration intact, and the swap itself is one synchronous section with no observable gap. pi-ai uses it instead of dispose-then-register — the old shape dropped every route when the new set conflicted, and its facts cache could then equal the registry's, so reverting to a working configuration never re-applied. Its registration facts are also sorted by provider, so a settings document that merely reorders keys no longer triggers a swap. DeepSeek's per-request snapshot now carries the credential facts, and resolveApiKey receives it instead of re-reading the raw config: a settings generation the resolver rejects can no longer contribute its literal key to a request the previous generation's endpoint serves. pi-ai only defers to the SDK's provider-native discovery when a profile names no credential at all; a configured apiKeyEnv that misses now fails with MISSING_CREDENTIAL naming the route and the reference, instead of handing pi-ai undefined and letting it authenticate with an unrelated ambient key. The eager boot-time credential probe is gone: it could run before the credentials service mounted and reported every failure as a missing key. The route stays registered and browsable; the first request gives the accurate error, whose guidance now leads with the credential store and mentions a literal apiKey last.
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/ |
Abstract LLM service + content-block vocabulary + chunk assembler | ctx.llm |
token-meter/ |
Replay-aware request and surface token measurement | ctx.tokenMeter |
llm-retry/ |
Exact-provider normal or unbounded request retry policy | (listens to agent/request-error) |
llm-deepseek/ |
DeepSeek API adapter (direct fetch + eventsource-parser SSE) | (registers on ctx.llm) |
llm-pi-ai/ |
Multi-provider adapter via @earendil-works/pi-ai |
(registers on ctx.llm) |
The interface lives at llm/llm/; adapters, retry policy, and the reusable token meter are flat siblings under the group. Requests route by provider, while model is passed through to the selected adapter. The route-owning adapter supplies retry policy and resolves available exact-model identity, context capacity, and reasoning metadata; the retry executor and token meter remain provider-agnostic. A new provider adapter registers one or more provider routes on ctx.llm without touching the consumers. See twin LLM adapters for the two shipping implementations, the replay token meter Agent Note for measurement ownership, and the routed model context Agent Note for capacity and compaction-policy ownership.
