LLMService API contract — the correct signatures for complete(), stream(), embed(), and response types. Use when calling LLMService from any layer, writing reasoning strategies, or building LLM-dependent features.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# LLMService API Contract
The most common source of bugs in this codebase is calling `LLMService` incorrectly. This skill defines the exact API contract.
## Service Definition
```typescript
export class LLMService extends Context.Tag("LLMService")<
LLMService,
{
readonly complete: (
request: CompletionRequest,
) => Effect.Effect<CompletionResponse, LLMErrors>;
readonly stream: (
request: CompletionRequest,
) => Effect.Effect<Stream.Stream<StreamEvent, LLMErrors>, LLMErrors>;
readonly completeStructured: <A>(
request: StructuredCompletionRequest<A>,
) => Effect.Effect<A, LLMErrors>;
readonly embed: (
texts: readonly string[],
model?: string,
) => Effect.Effect<readonly number[][], LLMErrors>;
readonly countTokens: (
messages: readonly LLMMessage[],
) => Effect.Effect<number, LLMErrors>;
readonly getModelConfig: () => Effect.Effect<ModelConfig, never>;
}
>() {}
```
## CompletionRequest — What You Send
```typescript
// Matches packages/llm-provider/src/types.ts — keep in sync
export type CompletionRequest = {
readonly messages: readonly LLMMessage[];
readonly model?: ModelConfig;

How to install
mdr add tylerjrbuell/reactive-agents-ts/llm-api-contract@sha256:0d0d279a875203fdThe line at the top of this page pins the label git:20260721.6379e94, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
