🧹 Nitpick comments (24)
pkg/client/agent/v1/websocket/client_channel.go (2)
52-63: Ensure host field usage aligns with connection logic.
TheGetURLmethod currently takes ahostparameter but referencesc.cOptions.Hostinternally. Confirm that this logic is intentional (perhaps ignoring the passed-inhost), or adjust as needed to avoid confusion in future refactors.
64-84: Add error handling or fallback for keepalive activation.
Whenc.cOptions.EnableKeepAliveis set to true, a goroutine is spawned to repeatedly send keepalive messages. If this goroutine fails or panics, it only logs an error. Consider adding a fallback or escalation mechanism, especially if keepalive is critical to the session.pkg/api/agent/v1/websocket/chan_router.go (2)
19-30: Verify error handling for default channel handler creation.
NewChanWithDefaultstartschans.Run()in a separate goroutine, but any returned error is only logged. If the run loop is critical, consider providing a mechanism to retry or escalate the error if needed.
380-392: Return more descriptive errors for unhandled message types.
TheUnhandledMessagemethod logs an unknown event and returnsErrInvalidMessageType. You may consider embedding context (e.g., partial message content) in the error for better debugging.pkg/api/agent/v1/websocket/chan_default.go (1)
414-440: Double-check logs and user-facing output for error information.
The error channel prints details about the error, which is valuable for users. Ensure these logs do not inadvertently leak sensitive data or become noisy in production.pkg/client/agent/v1/websocket/constants.go (2)
11-21: LGTM! Consider adding documentation for external constants.The constants have reasonable default values. Consider adding documentation comments for the external constants to explain their purpose and any constraints.
Add documentation comments for
DefaultConnectRetry,ChunkSize, andTerminationSleepsimilar to howMessageTypeKeepAliveis documented.
28-32: Consider making internal constants private.Internal constants should follow Go's naming convention of using lowercase for package-private entities.
// internal constants for retry, waits, back-off, etc. const ( - flushPeriod = 500 * time.Millisecond - pingPeriod = 5 * time.Second + _flushPeriod = 500 * time.Millisecond + _pingPeriod = 5 * time.Second )pkg/api/agent/v1/websocket/interfaces/interfaces.go (1)
11-11: Fix typo in documentation.There's a typo in the comment: "notifcations" should be "notifications".
-// AgentMessageChan is a callback used to receive notifcations for platforms messages +// AgentMessageChan is a callback used to receive notifications for platform messagespkg/client/agent/v1/websocket/types.go (1)
25-35: Enhance struct documentation.While the struct design is good, consider adding documentation for each field to improve code maintainability.
// WSChannel is a struct representing the websocket client connection using channels type WSChannel struct { + // WSClient is the embedded base WebSocket client *common.WSClient + // ctx is the context for managing the WebSocket connection lifecycle ctx context.Context + // ctxCancel is the function to cancel the context ctxCancel context.CancelFunc + // cOptions contains client configuration options cOptions *interfaces.ClientOptions + // tOptions contains settings configuration options tOptions *interfaces.SettingsConfigurationOptions + // chans is a slice of message channels for handling agent messages chans []*msginterface.AgentMessageChan + // router handles message routing router *commoninterfaces.Router }pkg/client/agent/init.go (1)
11-11: Add a link to the referenced documentation.The comment references
pkg/common/init.gobut doesn't provide a direct link. Consider adding a package documentation link for better developer experience.pkg/api/agent/v1/websocket/interfaces/constants.go (2)
11-12: Add detailed documentation for TypeResponse.The TypeResponse type alias would benefit from more detailed documentation explaining its purpose and usage in the context of WebSocket message handling.
15-23: Fix alignment of constant declarations.The constant declarations have inconsistent alignment. Consider aligning them for better readability:
const ( - TypeSettingsConfiguration = "SettingsConfiguration" - TypeUpdateInstructions = "UpdateInstructions" - TypeUpdateSpeak = "UpdateSpeak" - TypeInjectAgentMessage = "InjectAgentMessage" - TypeFunctionCallResponse = "FunctionCallResponse" - TypeKeepAlive = "KeepAlive" - TypeClose = "Close" + TypeSettingsConfiguration = "SettingsConfiguration" + TypeUpdateInstructions = "UpdateInstructions" + TypeUpdateSpeak = "UpdateSpeak" + TypeInjectAgentMessage = "InjectAgentMessage" + TypeFunctionCallResponse = "FunctionCallResponse" + TypeKeepAlive = "KeepAlive" + TypeClose = "Close" )pkg/api/agent/v1/websocket/types.go (2)
14-16: Fix incorrect struct name in comment.The comment refers to "DefaultCallbackHandler" but the struct is named "DefaultChanHandler". Update the comment to match the actual struct name.
-// DefaultCallbackHandler is a default callback handler for live transcription +// DefaultChanHandler is a default channel handler for live transcription // Simply prints the transcript to stdout
17-33: Add documentation for debug fields and standardize channel naming.
- Add documentation explaining the purpose of
debugWebsocketanddebugWebsocketVerbosefields- Consider standardizing channel naming (some use "Chan" suffix, others use "Response" suffix)
type DefaultChanHandler struct { + // debugWebsocket enables basic websocket debugging debugWebsocket bool + // debugWebsocketVerbose enables detailed websocket debugging debugWebsocketVerbose bool binaryChan chan *[]byte openChan chan *interfaces.OpenResponse - welcomeResponse chan *interfaces.WelcomeResponse + welcomeChan chan *interfaces.WelcomeResponse - conversationTextResponse chan *interfaces.ConversationTextResponse + conversationTextChan chan *interfaces.ConversationTextResponse // ... similar changes for other channelspkg/client/interfaces/v1/types-agent.go (1)
13-84: Consider adding field validation and enhancing documentation.The structs would benefit from:
- Field validation using struct tags (e.g., for required fields, value ranges)
- More detailed documentation for complex fields
- Examples of valid configurations
Example improvements:
type SettingsConfigurationOptions struct { - Type string `json:"type"` + Type string `json:"type" validate:"required,oneof=agent"` Audio Audio `json:"audio"` Agent Agent `json:"agent"` Context *Context `json:"context,omitempty"` } +// Audio configures both input and output audio settings type Audio struct { - Input *Input `json:"input,omitempty"` + Input *Input `json:"input,omitempty" validate:"required"` Output *Output `json:"output,omitempty"` } +// Input defines the audio input configuration +// Example: +// Input{ +// Encoding: "wav", +// SampleRate: 16000, +// } type Input struct { - Encoding string `json:"encoding,omitempty"` + Encoding string `json:"encoding,omitempty" validate:"required,oneof=wav mp3"` - SampleRate int `json:"sample_rate,omitempty"` + SampleRate int `json:"sample_rate,omitempty" validate:"required,oneof=8000 16000 44100"` }pkg/api/version/version.go (2)
37-40: Consider enhancing the log message for better debugging.While the host override logic is correct, the log message could be more descriptive.
- klog.V(4).Infof("overriding with agent host\n") + klog.V(4).Infof("overriding default host %s with agent host %s\n", common.DefaultHost, common.DefaultAgentHost)
69-72: Consider enhancing the log message for better debugging.While the version override logic is correct, the log message could be more descriptive.
- klog.V(4).Infof("overriding agent version with empty string since API isn't versioned\n") + klog.V(4).Infof("overriding agent version from %s to empty string since API isn't versioned\n", version)pkg/client/agent/client.go (1)
5-8: Enhance package documentation.Consider adding more details to the package documentation, such as usage examples and common patterns.
/* -This package provides the agent client implementation for the Deepgram API +Package agent provides the client implementation for the Deepgram Agent API. + +It offers various ways to establish WebSocket connections with different configuration options: +- NewWSUsingChanForDemo: Quick setup for demonstration purposes +- NewWSUsingChanWithDefaults: Setup with default options +- NewWSUsingChan: Full control over connection options + +Example usage: + ctx := context.Background() + options := agent.NewSettingsConfigurationOptions() + ws, err := agent.NewWSUsingChanForDemo(ctx, options) */pkg/client/interfaces/v1/options.go (1)
134-163: Consider validating required fields in constructor.While the default values are appropriate, the constructor could validate or warn about required fields that are left empty.
func NewSettingsConfigurationOptions() *SettingsConfigurationOptions { + klog.V(4).Infof("Creating new SettingsConfigurationOptions. Note: Think.Provider.Type and Think.Model are required fields.") return &SettingsConfigurationOptions{ Type: TypeSettingsConfiguration, Audio: Audio{pkg/client/agent/v1/websocket/new_using_chan.go (2)
36-36: Remove unnecessary gocritic ignore comment.The gocritic ignore comment appears unnecessary as there's no apparent linting issue to suppress.
-func NewUsingChanWithDefaults(ctx context.Context, options *clientinterfaces.SettingsConfigurationOptions, chans msginterfaces.AgentMessageChan) (*WSChannel, error) { // gocritic:ignore +func NewUsingChanWithDefaults(ctx context.Context, options *clientinterfaces.SettingsConfigurationOptions, chans msginterfaces.AgentMessageChan) (*WSChannel, error) {
66-109: Enhance error handling and logging.While the error handling is generally good, consider adding more context to errors and logging connection details.
func NewUsingChanWithCancel(ctx context.Context, ctxCancel context.CancelFunc, apiKey string, cOptions *clientinterfaces.ClientOptions, tOptions *clientinterfaces.SettingsConfigurationOptions, chans msginterfaces.AgentMessageChan) (*WSChannel, error) { klog.V(6).Infof("agent.New() ENTER\n") + defer klog.V(6).Infof("agent.New() LEAVE\n") if apiKey != "" { cOptions.APIKey = apiKey } err := cOptions.Parse() if err != nil { - klog.V(1).Infof("ClientOptions.Parse() failed. Err: %v\n", err) - return nil, err + return nil, fmt.Errorf("failed to parse client options: %w", err) } err = tOptions.Check() if err != nil { - klog.V(1).Infof("TranscribeOptions.Check() failed. Err: %v\n", err) - return nil, err + return nil, fmt.Errorf("failed to validate transcribe options: %w", err) } + klog.V(4).Infof("Initializing WebSocket connection with host: %s", cOptions.Host)pkg/api/agent/v1/websocket/interfaces/types.go (1)
35-40: MoveFunctionCallResponseto the response types section.The
FunctionCallResponsestruct appears to be a response type but is placed in the request/input section. Consider moving it to the response types section for better organization and clarity.examples/agent/websocket/simple/README.md (2)
3-3: Improve readability with concise phrasing.Consider these style improvements:
- Replace "in order to" with "to" for conciseness.
- Avoid repetition of "makes use of" by using "uses" instead.
Apply these changes:

pkg/client/agent/v1/websocket/client_channel.go (3)
25-29: Consider verifying concurrency context usage.
TheConnectmethod reassignsc.ctxandc.ctxCancelwith a new context, which is also set inConnectWithCancel. Verify that no concurrent goroutines are using the old context or referencing the old cancel function, to avoid race conditions or unexpected cancellations.
113-167: Potential performance consideration in the Stream method.
TheStreammethod repeatedly reads from anio.Readerand writes chunks. If there's a need for higher throughput or partial reads, consider using a pooled buffer or an adaptive chunk size. Otherwise, this approach is straightforward and correct.
243-284: Validate recovered panic handling in ping() method.
The panic recovery logs the error and callsProcessError. However, subsequent logic within the same goroutine is terminated. Confirm that the overall WebSocket channel or main process can recover fully from these panics.pkg/api/agent/v1/websocket/chan_router.go (1)
149-164: ProcessGeneric function is well-structured.
The generic approach of taking a message type, printing debug info, and invoking a callback action is clear and maintainable. Good job keeping it consistently logged.pkg/client/interfaces/v1/constants.go (1)
15-17: LGTM!The constant follows Go naming conventions and is appropriately placed in the constants block.
pkg/client/interfaces/interfaces.go (1)

pkg/api/version/agent-version.go (2)
12-14: Address API versioning concern.The TODO comment raises a valid concern about the lack of API versioning. This could lead to breaking changes affecting clients in the future. Consider implementing proper versioning strategy.
30-32: Clarify commented code and add input validation.
- The commented-out
optionsparameter suggests incomplete implementation. Please clarify if this is intended for future use.- Consider adding input validation for
host,version, andpathparameters.func GetAgentAPI(ctx context.Context, host, version, path string /*options *interfaces.SettingsConfigurationOptions,*/, args ...interface{}) (string, error) { + if host == "" || version == "" || path == "" { + return "", fmt.Errorf("host, version, and path must not be empty") + } return getAPIURL(ctx, "agent", host, version, path, nil, args...) }pkg/api/version/constants.go (1)

🧹 Nitpick comments (9)
pkg/api/agent/v1/websocket/interfaces/types.go (3)
5-5: Consider a more specific package name.The package name
interfacesv1is quite generic. Consider usingagentinterfacesorwsinterfacesto better reflect its specific purpose within the Agent API WebSocket implementation.
35-40: Move FunctionCallResponse to the response section.The
FunctionCallResponsestruct is placed in the request/input section but represents a response type. Consider moving it to the response section for better code organization.
18-21: Add validation for required fields.Consider adding validation tags or implementing validation methods for required fields in request structs. This would help catch invalid requests early.
For example:
type UpdateInstructions struct { - Type string `json:"type,omitempty"` - Instructions string `json:"instructions,omitempty"` + Type string `json:"type" validate:"required"` + Instructions string `json:"instructions" validate:"required"` }Also applies to: 24-27, 30-33
pkg/client/interfaces/v1/types-agent.go (2)
13-18: Consider adding field documentation.The struct fields would benefit from documentation comments explaining their purpose and constraints. This is especially important for public APIs.
type SettingsConfigurationOptions struct { + // Type specifies the type of configuration message Type string `json:"type"` + // Audio contains the input/output audio configuration Audio Audio `json:"audio"` + // Agent contains the listen/think/speak configuration Agent Agent `json:"agent"` + // Context contains optional message handling and replay settings Context *Context `json:"context,omitempty"` }
78-82: Consider adding required tags for mandatory fields.The
Agentstruct's fields appear to be required based on the JSON structure, but this isn't reflected in the struct tags.type Agent struct { - Listen Listen `json:"listen"` - Think Think `json:"think"` - Speak Speak `json:"speak"` + Listen Listen `json:"listen" binding:"required"` + Think Think `json:"think" binding:"required"` + Speak Speak `json:"speak" binding:"required"` }pkg/api/agent/v1/websocket/interfaces/interfaces.go (1)
12-28: Consider adding method documentation.While the interface is well-structured, adding documentation for each method would improve usability. Consider documenting:
- Purpose of each method
- Expected usage patterns
- Why channels are returned as slices
type AgentMessageChan interface { + // GetBinary returns channels that receive raw binary messages GetBinary() []*chan *[]byte + // GetOpen returns channels that receive connection open events GetOpen() []*chan *OpenResponse // ... (add similar documentation for other methods) }pkg/api/agent/v1/websocket/interfaces/constants.go (1)
11-12: Consider improving type alias documentation.The TypeResponse type alias would benefit from more detailed documentation explaining its purpose and relationship to commoninterfaces.TypeResponse.
-// These are the message types that can be received from the live API +// TypeResponse represents the base type for all Agent API messages. +// It extends commoninterfaces.TypeResponse to maintain consistency +// across different parts of the SDK while allowing for agent-specific +// message handling. type TypeResponse commoninterfaces.TypeResponsepkg/api/agent/v1/websocket/chan_router.go (1)
402-413: Consider adding buffer size for binary channel.The
Binarymethod sends data to unbuffered channels which could block if receivers are slow. Consider adding a buffer to prevent potential deadlocks.Apply this diff to add buffering:
func (r *ChanRouter) Binary(byMsg []byte) error { klog.V(6).Infof("router.Binary ENTER\n") klog.V(5).Infof("Binary Message:\n%s...\n", hex.EncodeToString(byMsg[:20])) + // Use buffered channels to prevent blocking + const bufferSize = 10 + for _, ch := range r.binaryChan { + select { + case *ch <- &byMsg: + // Message sent successfully + default: + klog.V(1).Infof("Binary channel buffer full, dropping message\n") + } + } - for _, ch := range r.binaryChan { - *ch <- &byMsg - } klog.V(6).Infof("router.Binary LEAVE\n") return nil }pkg/api/agent/v1/websocket/chan_default.go (1)
157-170: Improve file handling in debug mode.The file handling in the binary channel processing could be improved to ensure proper cleanup and error handling.
Apply this diff to improve file handling:
if dch.debugWebsocketVerbose { fmt.Printf("Dumping to verbose.wav\n") - file, err := os.OpenFile("verbose.wav", os.O_APPEND|os.O_CREATE|os.O_WRONLY, 0o644) - if err != nil { - fmt.Printf("Failed to open file. Err: %v\n", err) - continue - } - - _, err = file.Write(*br) - file.Close() - - if err != nil { - fmt.Printf("Failed to write to file. Err: %v\n", err) - continue - } + func() { + file, err := os.OpenFile("verbose.wav", os.O_APPEND|os.O_CREATE|os.O_WRONLY, 0o644) + if err != nil { + klog.V(1).Infof("Failed to open file. Err: %v\n", err) + return + } + defer file.Close() + + if _, err = file.Write(*br); err != nil { + klog.V(1).Infof("Failed to write to file. Err: %v\n", err) + return + } + }() }

36-36: LGTM! Verify channel-based implementation across the codebase.The change to
NewWebSocketUsingChanaligns with the broader refactoring to standardize WebSocket client creation methods.Let's verify the consistency of this change across the codebase:
✅ Verification successful
✅ Channel-based WebSocket implementation verified across codebase
The migration to channel-based WebSocket client creation is complete and consistent. All relevant code paths are using the new methods with no remnants of the old implementation.
🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash # Description: Check for any remaining old WebSocket client creation methods # that haven't been migrated to the new channel-based approach # Search for old method names echo "Checking for old method usage..." rg "NewWebSocket[^U]" --type go # Search for new method names to confirm migration echo "Verifying new method adoption..." rg "NewWebSocketUsingChan|NewWSUsingChan" --type goLength of output: 7380

NewWebSocketUsingChanis consistent with the standardization effort while preserving the test's purpose of demonstrating retry behavior.tests/edge_cases/timeout/main.go (1)
31-31: Consider consistent naming across the codebase.While the change to channel-based implementation is good, the method name uses 'WS' instead of 'WebSocket' used in other files. Consider standardizing to either
NewWebSocketUsingChanWithDefaultsorNewWSUsingChanWithDefaultsacross all files for consistency.Let's check the naming patterns across the codebase:

144-144: LGTM! Method name change aligns with SDK's new WebSocket client creation pattern.The change from
NewWebSockettoNewWebSocketUsingCallbackmakes the callback-based nature of the client more explicit while maintaining the same functionality.Let's verify this change is consistent across the codebase:
✅ Verification successful
✅ Verified: WebSocket client creation methods are consistently updated across the codebase
The change from
NewWebSockettoNewWebSocketUsingCallbackis part of a complete and consistent update across the codebase. All WebSocket client instantiations now explicitly indicate their message handling approach (callback or channel-based).🏁 Scripts executed

52-66: LGTM! Well-documented message type discriminator.The
MessageTypestruct is well-documented with a clear example, making it easy to understand its purpose in message unmarshalling.
104-109: Address TODOs and improve type definitions for function calls.The function call related structs have undefined types marked with TODOs:
- In
FunctionCallRequestResponse,Inputis usingmap[string]string- In
FunctionCallingResponse,Outputis usingmap[string]stringConsider:
- Defining proper types for function inputs and outputs instead of using generic string maps
- Adding validation for required fields
- Adding documentation about expected input/output formats
Example improvement:
// FunctionInput represents the structured input for a function call type FunctionInput struct { Parameters map[string]interface{} `json:"parameters" validate:"required"` Schema string `json:"schema,omitempty"` } type FunctionCallRequestResponse struct { Type string `json:"type" validate:"required"` FunctionName string `json:"function_name" validate:"required"` FunctionCallID string `json:"function_call_id" validate:"required"` Input FunctionInput `json:"input" validate:"required"` }Would you like me to help define proper types for function inputs and outputs?

211-211: Fix grammar: Use "a URL" instead of "an URL".The article "an" is used before words that begin with a vowel sound. Since "URL" is pronounced starting with a consonant sound ("you"), it should be preceded by "a" instead of "an".
