type AntigravityAgentConfig 

type AntigravityAgentConfig struct {
	Type           string `json:"type"`
	Model          string `json:"model,omitempty"`
	MaxTotalTokens int    `json:"max_total_tokens,omitempty"`
}

AntigravityAgentConfig selects the managed agent's underlying model and optional total-token budget.

type AntigravityClient 

type AntigravityClient struct {
	// contains filtered or unexported fields
}

func NewAntigravityClient 

func NewAntigravityClient(config AntigravityClientConfig) (*AntigravityClient, error)

func (*AntigravityClient) Cancel 

func (c *AntigravityClient) Cancel(ctx context.Context, interactionID string) (*AntigravityInteraction, error)

Cancel stops a still-running background interaction using the documented POST /interactions/{id}/cancel endpoint.

func (*AntigravityClient) Create 

func (c *AntigravityClient) Create(ctx context.Context, request AntigravityLifecycleRequest) (*AntigravityInteraction, error)

Create starts an interaction. Background executions return quickly with an in_progress resource; callers can use Get or Poll for state transitions.

func (*AntigravityClient) Delete 

func (c *AntigravityClient) Delete(ctx context.Context, interactionID string) error

Delete removes a stored interaction. It is separate from Cancel: cancelling stops execution while deleting removes the provider-side record.

func (*AntigravityClient) Get 

func (c *AntigravityClient) Get(ctx context.Context, interactionID string) (*AntigravityInteraction, error)

Get retrieves the current interaction state. It does not persist the body; callers decide which fields to expose or log.

func (*AntigravityClient) Poll 

func (c *AntigravityClient) Poll(ctx context.Context, interactionID string, interval time.Duration, attempts int) (*AntigravityInteraction, error)

Poll waits for a terminal state with bounded attempts. It is intentionally opt-in so a background request never consumes a worker indefinitely.

type AntigravityClientConfig 

type AntigravityClientConfig struct {
	BaseURL     string
	APIKey      string
	APIRevision string
	HTTPClient  *http.Client
}

AntigravityClientConfig contains connection settings only. APIKey is held in memory for the request and is never included in an error, response, or persisted model.

type AntigravityConfig 

type AntigravityConfig struct {
	BaseURL        string
	Agent          string
	Environment    string
	Model          string
	MaxTotalTokens int
}

AntigravityConfig contains non-secret connection and agent settings. The API key remains in the channel credential and is never copied here.

func (AntigravityConfig) BuildInteractionRequest 

func (c AntigravityConfig) BuildInteractionRequest(input string) ([]byte, error)

BuildInteractionRequest validates and serializes a text/image-free prompt. The current relay boundary only accepts text; multimodal and stateful continuation need explicit lifecycle handling before being enabled.

func (AntigravityConfig) Endpoint 

func (c AntigravityConfig) Endpoint() (string, error)

Endpoint returns the Interactions API URL after validating the configured base. Credentials and query parameters are deliberately rejected.

func (AntigravityConfig) Validate 

func (c AntigravityConfig) Validate() error

type AntigravityGroundingToolCount 

type AntigravityGroundingToolCount struct {
	Type  string `json:"type,omitempty"`
	Count int64  `json:"count,omitempty"`
}

type AntigravityHTTPError 

type AntigravityHTTPError struct {
	StatusCode int
	Code       string
}

AntigravityHTTPError deliberately omits response bodies. Upstream errors can contain prompt fragments or provider metadata, and returning only the status/code keeps them out of logs and API error strings.

func (*AntigravityHTTPError) Error 

func (e *AntigravityHTTPError) Error() string

type AntigravityInteraction 

type AntigravityInteraction struct {
	ID                    string                        `json:"id,omitempty"`
	Object                string                        `json:"object,omitempty"`
	Status                string                        `json:"status,omitempty"`
	Agent                 string                        `json:"agent,omitempty"`
	Model                 string                        `json:"model,omitempty"`
	EnvironmentID         string                        `json:"environment_id,omitempty"`
	PreviousInteractionID string                        `json:"previous_interaction_id,omitempty"`
	OutputText            string                        `json:"output_text,omitempty"`
	Usage                 *AntigravityUsage             `json:"usage,omitempty"`
	Errors                []AntigravityInteractionError `json:"errors,omitempty"`
}

AntigravityInteraction is the safe, typed subset returned by create/get/ cancel. Steps and output text are intentionally represented only as fields needed by the caller; this client does not store or log them.

type AntigravityInteractionError 

type AntigravityInteractionError struct {
	Code    string `json:"code,omitempty"`
	Message string `json:"message,omitempty"`
}

type AntigravityInteractionRequest 

type AntigravityInteractionRequest struct {
	Agent       string                  `json:"agent"`
	Input       string                  `json:"input"`
	Environment string                  `json:"environment,omitempty"`
	AgentConfig *AntigravityAgentConfig `json:"agent_config,omitempty"`
}

AntigravityInteractionRequest is the minimal request supported by the managed Antigravity agent. Additional tools and stateful continuation are intentionally not represented until the relay lifecycle supports them.

type AntigravityLifecycleAgentConfig 

type AntigravityLifecycleAgentConfig struct {
	Type           string `json:"type,omitempty"`
	MaxTotalTokens int    `json:"max_total_tokens,omitempty"`
}

AntigravityLifecycleAgentConfig contains the small, explicitly supported dynamic-agent subset. The relay does not accept arbitrary tool, safety, or generation configuration until each field has a policy and billing model.

type AntigravityLifecycleRequest 

type AntigravityLifecycleRequest struct {
	Agent                 string                           `json:"agent"`
	Input                 string                           `json:"input"`
	Environment           string                           `json:"environment,omitempty"`
	Background            bool                             `json:"background,omitempty"`
	PreviousInteractionID string                           `json:"previous_interaction_id,omitempty"`
	AgentConfig           *AntigravityLifecycleAgentConfig `json:"agent_config,omitempty"`
}

AntigravityLifecycleRequest is the first-phase create payload. It is kept separate from the normal Gemini request DTO so this endpoint cannot silently inherit GenerateContent fields or route through the regular Gemini path.

Environment accepts the documented "remote" value or a provider environment ID when continuing a prior interaction. Local files, credentials, and process state are never mounted by this client.

func (AntigravityLifecycleRequest) Validate 

func (r AntigravityLifecycleRequest) Validate() error

type AntigravityModalityTokens 

type AntigravityModalityTokens struct {
	Modality string `json:"modality,omitempty"`
	Tokens   int64  `json:"tokens,omitempty"`
}

AntigravityModalityTokens and AntigravityGroundingToolCount model the provider usage response without retaining the full upstream payload.

type AntigravityUsage 

type AntigravityUsage struct {
	CachedTokensByModality []AntigravityModalityTokens     `json:"cached_tokens_by_modality,omitempty"`
	InputTokensByModality  []AntigravityModalityTokens     `json:"input_tokens_by_modality,omitempty"`
	OutputTokensByModality []AntigravityModalityTokens     `json:"output_tokens_by_modality,omitempty"`
	TotalCachedTokens      int64                           `json:"total_cached_tokens,omitempty"`
	TotalInputTokens       int64                           `json:"total_input_tokens,omitempty"`
	TotalOutputTokens      int64                           `json:"total_output_tokens,omitempty"`
	TotalThoughtTokens     int64                           `json:"total_thought_tokens,omitempty"`
	TotalToolUseTokens     int64                           `json:"total_tool_use_tokens,omitempty"`
	TotalTokens            int64                           `json:"total_tokens,omitempty"`
	GroundingToolCount     []AntigravityGroundingToolCount `json:"grounding_tool_count,omitempty"`
}

type GeminiModelsResponse 

type GeminiModelsResponse struct {
	Models        []dto.GeminiModel `json:"models"`
	NextPageToken string            `json:"nextPageToken"`
}
