Variables ¶
var ErrClaudeStreamError = errors.New("claude stream error")
ErrClaudeStreamError marks a failure Anthropic reported mid-stream through an error event. The wrapping error carries the error type and message.

Types ¶
type Provider ¶
type Provider struct {
providers.BaseProvider
// contains filtered or unexported fields
}
Provider implements the Provider interface for Anthropic Claude
func NewProvider ¶
func NewProvider(id, model, baseURL string, defaults providers.ProviderDefaults, includeRawOutput bool) *Provider
NewProvider creates a new Claude provider
func NewProviderWithCredential ¶
func NewProviderWithCredential( id, model, baseURL string, defaults providers.ProviderDefaults, includeRawOutput bool, cred providers.Credential, platform string, platformConfig *providers.PlatformConfig, ) *Provider
NewProviderWithCredential creates a new Claude provider with explicit credential.
When baseURL is empty the URL is derived from platformConfig for the platforms that support it: Vertex (`publishers/anthropic/models`) and Azure (`openai/deployments/{deployment}`). Callers that pass an explicit baseURL always win.
func (*Provider) CalculateCost ¶
CalculateCost calculates detailed cost breakdown including optional cached tokens. Thin wrapper over costFromUsage, kept for the Provider interface's legacy signature (cachedTokens here means cache READS only — callers that also have cache-write counts, e.g. wire claudeUsage, should call costFromUsage directly instead so cache writes aren't dropped).
func (*Provider) GetMultimodalCapabilities ¶
func (p *Provider) GetMultimodalCapabilities() providers.MultimodalCapabilities
GetMultimodalCapabilities returns Claude's multimodal support capabilities. When the provider config declares its capabilities, the declaration is authoritative for which modalities are enabled; otherwise Claude's built-in defaults apply (images + documents, no audio/video).
func (*Provider) Predict ¶
func (p *Provider) Predict(ctx context.Context, req providers.PredictionRequest) (providers.PredictionResponse, error)
Predict sends a predict request to Claude
func (*Provider) PredictStream ¶
func (p *Provider) PredictStream( ctx context.Context, req providers.PredictionRequest, ) (<-chan providers.StreamChunk, error)
PredictStream performs a streaming prediction request to Claude. On Bedrock, falls back to non-streaming Predict since Bedrock uses binary event-stream encoding that requires AWS-specific parsing.
func (*Provider) SupportsPromptCaching ¶
SupportsPromptCaching reports whether prompt caching is active for this provider (supported and not disabled by config). The pipeline uses this to decide whether a zero-cache-read tool loop is worth warning about, so providers without caching don't produce false "caching not engaging" warnings.
type ToolProvider ¶
type ToolProvider struct {
*Provider
// contains filtered or unexported fields
}
ToolProvider extends ClaudeProvider with tool support
func NewToolProvider ¶
func NewToolProvider(id, model, baseURL string, defaults providers.ProviderDefaults, includeRawOutput bool) *ToolProvider
NewToolProvider creates a new Claude provider with tool support
func NewToolProviderWithCredential ¶
func NewToolProviderWithCredential( id, model, baseURL string, defaults providers.ProviderDefaults, includeRawOutput bool, cred providers.Credential, platform string, platformConfig *providers.PlatformConfig, ) *ToolProvider
NewToolProviderWithCredential creates a Claude tool provider with explicit credential.
func (*ToolProvider) BuildTooling ¶
func (p *ToolProvider) BuildTooling(descriptors []*providers.ToolDescriptor) (providers.ProviderTools, error)
BuildTooling converts tool descriptors to Claude format
func (*ToolProvider) PredictStreamWithTools ¶
func (p *ToolProvider) PredictStreamWithTools( ctx context.Context, req providers.PredictionRequest, tools interface{}, toolChoice string, ) (<-chan providers.StreamChunk, error)
PredictStreamWithTools performs a streaming predict request with tool support.
func (*ToolProvider) PredictWithTools ¶
func (p *ToolProvider) PredictWithTools( ctx context.Context, req providers.PredictionRequest, tools providers.ProviderTools, toolChoice string, ) (providers.PredictionResponse, []types.MessageToolCall, error)
PredictWithTools performs a predict request with tool support
