AgentClient is the low-level raw transport for talking to agentd through a running sandbox’s relay socket. Most applications should use Sandbox, Exec, and filesystem helpers instead. Use this API when you are building protocol-level tools or higher-level SDK helpers. All request bodies and response bodies are raw CBOR bytes. The SDK handles framing and correlation ids, but it does not encode or decode the CBOR message body for you. The raw body is the full CBOR-encoded protocol Message body: v, t, and p. It is not just the inner payload. 
import m "github.com/superradcompany/microsandbox/sdk/go"

client, err := m.ConnectAgentSandbox(ctx, "dev")
if err != nil {
    return err
}
defer client.Close()

ready, err := client.ReadyBytes()
if err != nil {
    return err
}
_ = ready

Constants

NameTypeDescription
FlagTerminal / FLAG_TERMINALuint8Last frame for a correlation id
FlagSessionStart / FLAG_SESSION_STARTuint8First frame of a streaming session
FlagShutdown / FLAG_SHUTDOWNuint8Shutdown frame

​
ConnectAgentSandbox()

func ConnectAgentSandbox(ctx context.Context, name string) (*AgentClient, error)
Connect to a running sandbox by name.

​
ConnectAgentPath()

func ConnectAgentPath(ctx context.Context, path string) (*AgentClient, error)
Connect to an agent relay socket by path.

​
Request()

func (c *AgentClient) Request(ctx context.Context, flags uint8, body []byte) (*RawFrame, error)
Send one raw frame and wait for one response frame.

​
Stream()

func (c *AgentClient) Stream(ctx context.Context, flags uint8, body []byte) (*AgentStream, error)
Open a raw streaming session. 
stream, err := client.Stream(ctx, m.FlagSessionStart, body)
if err != nil {
    return err
}
defer stream.Close(ctx)

for {
    frame, err := stream.Next(ctx)
    if err != nil {
        return err
    }
    if frame == nil || frame.Flags&m.FlagTerminal != 0 {
        break
    }
}

​
Send()

func (c *AgentClient) Send(ctx context.Context, id uint32, flags uint8, body []byte) error
Send a follow-up frame on an existing correlation id. Use this with the id returned by AgentStream.ID().

​
ReadyBytes()

func (c *AgentClient) ReadyBytes() ([]byte, error)
Return the cached handshake core.ready frame body as CBOR bytes.

​
Close()

func (c *AgentClient) Close() error
Release the client handle. Calling it more than once is safe.

​
CloseCtx()

func (c *AgentClient) CloseCtx(ctx context.Context) error
Release the client handle with a caller-controlled context.

​
RawFrame

type RawFrame struct {
    ID    uint32
    Flags uint8
    Body  []byte
}
ID is the protocol correlation id, Flags is the frame flag byte, and Body is the CBOR-encoded protocol message body.

​
AgentStream

func (s *AgentStream) ID() uint32
func (s *AgentStream) Next(ctx context.Context) (*RawFrame, error)
func (s *AgentStream) Close(ctx context.Context) error
ID() returns the protocol correlation id. Pass it to AgentClient.Send() for follow-up frames in the same session. Next() returns nil, nil at EOF.
