Wraps @anthropic-ai/claude-agent-sdk so Claude Pro/Max subscribers (who
do not have a console API key) can use this library by authenticating
through the local `claude` CLI. Subscribers run `claude login` once and
the provider picks up the credentials automatically.
Provider behavior:
- query() is invoked in single-turn mode (maxTurns: 1, allowedTools: [])
to behave as plain text completion by default. Both knobs are
configurable for agentic use cases.
- Conversation history is flattened to a single prompt with role labels.
- doStream() emits text deltas as the SDK yields successive assistant
messages. doComplete() accumulates and returns the final result.
- SDKAssistantMessageError codes (authentication_failed, billing_error,
rate_limit, model_not_found, ...) map to AIErrorType variants.
- ClaudeCodeConfig.apiKey is optional — when omitted the SDK falls back
to ANTHROPIC_API_KEY or local subscription credentials. The base
validator is overridden to allow this.
Tradeoffs:
- Requires the `claude` CLI installed and logged in on the host. This
is not suitable for typical server-side production deployments; it is
the official path for subscription accounts.
- Higher latency (CLI process spawn) than the direct Anthropic API.
- The agent SDK is heavy. Bundle grows ~750KB; bun build now uses
--target node so the SDK's Node built-in imports resolve correctly.
Wired into PROVIDER_REGISTRY ('claude-code'), createClaudeCodeProvider,
SUPPORTED_PROVIDERS, and re-exported from the package entry.
The @google/generative-ai SDK has been deprecated by Google. This switches
to the successor @google/genai package and rewrites the Gemini provider
against the new stateless models/chats API.
BREAKING CHANGE: GeminiConfig.safetySettings now uses the SafetySetting
type from @google/genai. Consumers passing this field must update their
import from '@google/generative-ai' to '@google/genai'. The shape of the
type is similar but not identical.
Notable simplifications enabled by the new SDK:
- No per-model client caching: generateContent specifies model per-call
- Single code path for both single- and multi-turn (full contents array
is passed to generateContent directly; no more startChat branching)
- Stream chunks expose .text as a property (was .text() method)
- Stream iteration is direct on the response (no .stream sub-property)
Default model bumped from gemini-1.5-flash to gemini-2.5-flash.
- Add typescript ^6.0.0 as devDependency for verified builds
- Widen peerDependency to ^5 || ^6 to keep TS 5 consumers supported
- tsconfig.build.json: set explicit rootDir (required by TS 6 when outDir is set)
- tsconfig.build.json: replace deprecated moduleResolution "node" with "bundler"
Also refreshes bun.lock to pick up @anthropic-ai/sdk 0.65.0 and
@types/node 24.12.4 within existing version ranges. All bumps stay
within the same major to avoid breaking changes.
