About
From README.md in 0.1.3.
Shared Cordis service for model-role routing, bounded auxiliary calls, cancellation, and usage receipts. It is a supporting service, not a user-facing feature. Loading it does not start inference.
Install
Requires Node.js ≥22 and DSH 0.1.7-rc.2. The host must provide llm, storageDomain, connection, and webServer.
dsh plugin --profile web add @klarkxy/dsh-ai-services
DSH Editor includes this package as a locked core service. Feature plugins call ctx.aiServices.activate(plugin) when they need a model; this package never calls the model by itself.
Routing
Roles weak, normal, strong, and fantasy represent Quick, Chat, Thinking, and Fantasy (the Haiku, Sonnet, Opus, and Fable tiers respectively). They can bind models from any provider. Built-in plugins never default to Fantasy; it is reserved for explicit user selection. Unbound tiers inherit Chat, falling back to the host default chat model if Chat is unset. The host default is read on each call, so standalone plugins need no Editor initialization. A missing default chat model fails visibly. An explicit invalid provider/model/reasoning choice fails without switching to another route. Session targets use the native Host projection, the request header, and the host default model; they do not call the removed session.models RPC.
Policy is one storage-domain record with compare-and-swap revision. It does not copy provider credentials. Host compatibility imports use importPurposes to persist missing defaults and a one-time marker atomically.
Auxiliary calls are plain text with no tools. Limits cap input size, output tokens, wall time, attempts, and per-provider concurrency. Interactive work is queued ahead of background work. Native agent-loop requests, when present, occupy the same provider's foreground so background jobs wait. run({ insert: { maxChars } }) supports bounded text candidates; other auxiliary calls still require a successful complete stream.
Usage receipts store token counts when the adapter reports them. Cost is null when unknown. Prompts and secrets are not stored.
Host RPC is /dsh-ai-services (status, update, resolve, usage) and requires the host authorization policy.
