var ErrCapacityExceeded = errors.New("acp instance capacity exceeded")

var ErrInvalidRequest = errors.New("invalid acp request")

ErrInvalidRequest marks a client-correctable problem with a session or transcript request (a disabled service, a cwd outside allowed_roots, or a missing session id). Callers map it to HTTP 400; service-not-found maps to 404 and unwrapped agent/transport failures map to 502.

var ErrPermissionNotFound = fmt.Errorf("acp permission request not found")

ErrPermissionNotFound reports a decision for a permission request that is unknown, already answered, or expired (the in-agent wait timed out and failed closed).

Types

type ActivityTracker 

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

func NewActivityTracker 

func NewActivityTracker() *ActivityTracker

func (*ActivityTracker) Begin 

func (t *ActivityTracker) Begin(scope string) (func(), error)

func (*ActivityTracker) IsActive 

func (t *ActivityTracker) IsActive(scope string) bool

func (*ActivityTracker) List 

func (t *ActivityTracker) List() []InFlightTurn

type EventSink 

type EventSink func(TurnEvent) error

type InFlightTurn 

type InFlightTurn struct {
	Scope string `json:"scope"`
}

type ListSessionsRequest 

type ListSessionsRequest struct {
	CWD    string `json:"cwd,omitempty"`
	Cursor string `json:"cursor,omitempty"`
}

type ListSessionsResponse 

type ListSessionsResponse struct {
	Sessions   []SessionInfo `json:"sessions"`
	NextCursor string        `json:"next_cursor,omitempty"`
}

type Manager 

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

func NewManager 

func NewManager(services *acpservice.Manager) *Manager

func (*Manager) Close 

func (m *Manager) Close()

Close stops the janitor and tears down every pooled instance, killing the underlying agent subprocesses. It is safe to call more than once.

func (*Manager) CloseScope 

func (m *Manager) CloseScope(scope string) bool

CloseScope tears down the pooled instance for an exact scope, returning whether one was closed. An in-flight turn on that scope will fail on its next request.

func (*Manager) CloseService 

func (m *Manager) CloseService(serviceID string) int

CloseService tears down every pooled instance for a service and returns the count closed. This is used after process-affecting service config changes so the next turn starts an agent with the latest launch environment.

func (*Manager) CloseThread 

func (m *Manager) CloseThread(serviceID, threadID string) int

CloseThread tears down every pooled instance for a service+thread and returns the count closed. Intended as an operator escape hatch for a wedged thread.

func (*Manager) ListInFlight 

func (m *Manager) ListInFlight() []InFlightTurn

func (*Manager) ListInstances 

func (m *Manager) ListInstances() []PooledInstanceInfo

ListInstances returns an operator-facing snapshot of the pooled instances, including each instance's cached session metadata, sorted by scope.

func (*Manager) ListPendingPermissions 

func (m *Manager) ListPendingPermissions() []PendingPermissionInfo

ListPendingPermissions returns the in-flight interactive permission requests awaiting a decision.

func (*Manager) ListSessions 

func (m *Manager) ListSessions(ctx context.Context, serviceID string, req ListSessionsRequest) (ListSessionsResponse, error)

func (*Manager) LoadTranscript 

func (m *Manager) LoadTranscript(ctx context.Context, serviceID string, req TranscriptRequest) (TranscriptResponse, error)

func (*Manager) ResolvePermission 

func (m *Manager) ResolvePermission(decision PermissionDecision) error

ResolvePermission answers one pending interactive permission request. The outcome must be the ACP discriminator "selected" (with the chosen option id exactly as offered by the agent) or "cancelled".

func (*Manager) ServeTurn 

func (m *Manager) ServeTurn(ctx context.Context, serviceID string, req TurnRequest, emit EventSink) error

type PendingPermissionInfo 

type PendingPermissionInfo struct {
	RequestID string          `json:"request_id"`
	ServiceID string          `json:"service_id"`
	SessionID string          `json:"session_id,omitempty"`
	CreatedAt time.Time       `json:"created_at"`
	Data      json.RawMessage `json:"data,omitempty"`
}

PendingPermissionInfo describes one in-flight interactive permission request. Data carries the raw ACP session/request_permission params (tool call context plus the agent's permission options and their exact ids).

type PermissionDecision 

type PermissionDecision struct {
	RequestID string `json:"request_id"`
	Outcome   string `json:"outcome"`
	OptionID  string `json:"option_id,omitempty"`
}

PermissionDecision is the north-side answer to a pending interactive permission request. Outcome follows the ACP RequestPermissionOutcome discriminators: "selected" (with the chosen option id) or "cancelled".

type PooledInstanceInfo 

type PooledInstanceInfo struct {
	Scope     string          `json:"scope"`
	SessionID string          `json:"session_id,omitempty"`
	Alive     bool            `json:"alive"`
	Active    bool            `json:"active"`
	LastUsed  time.Time       `json:"last_used"`
	IdleTTL   time.Duration   `json:"idle_ttl,omitempty"`
	Metadata  SessionMetadata `json:"metadata"`
}

PooledInstanceInfo is the operator-facing view of one pooled agent instance.

type SessionInfo 

type SessionInfo struct {
	SessionID string          `json:"session_id"`
	CWD       string          `json:"cwd"`
	Title     string          `json:"title,omitempty"`
	UpdatedAt *time.Time      `json:"updated_at,omitempty"`
	Meta      json.RawMessage `json:"_meta,omitempty"`
}

type SessionMetadata 

type SessionMetadata struct {
	ConfigOptions     json.RawMessage `json:"config_options,omitempty"`
	AvailableCommands json.RawMessage `json:"available_commands,omitempty"`
	SessionInfo       json.RawMessage `json:"session_info,omitempty"`
	Mode              json.RawMessage `json:"mode,omitempty"`
	Usage             json.RawMessage `json:"usage,omitempty"`
}

SessionMetadata is the cached structured state of one pooled session. Every field carries the raw ACP update object of its kind (config_option_update, available_commands_update, session_info_update, current_mode_update, usage_update).

type TranscriptMessage 

type TranscriptMessage struct {
	Role string `json:"role"`
	Text string `json:"text"`
}

TranscriptMessage is one coalesced replayed message. Role is one of user, assistant, or reasoning.

type TranscriptRequest 

type TranscriptRequest struct {
	SessionID string `json:"session_id"`
	CWD       string `json:"cwd,omitempty"`
}

type TranscriptResponse 

type TranscriptResponse struct {
	SessionID string              `json:"session_id"`
	Messages  []TranscriptMessage `json:"messages"`
}

type TurnEvent 

type TurnEvent struct {
	Event      string          `json:"-"`
	SessionID  string          `json:"session_id,omitempty"`
	RequestID  string          `json:"request_id,omitempty"`
	Text       string          `json:"text,omitempty"`
	StopReason string          `json:"stop_reason,omitempty"`
	Message    string          `json:"message,omitempty"`
	Data       json.RawMessage `json:"data,omitempty"`
}

type TurnRequest 

type TurnRequest struct {
	ThreadID        string            `json:"thread_id"`
	SessionID       string            `json:"session_id,omitempty"`
	Input           string            `json:"input"`
	CWD             string            `json:"cwd,omitempty"`
	Model           string            `json:"model,omitempty"`
	FreshSession    bool              `json:"fresh_session,omitempty"`
	ConfigOverrides map[string]string `json:"config_overrides,omitempty"`
