* feat: add context window usage display to task session
- Add TokenUsageDisplay component showing context window usage as a horizontal progress bar
- Add useSessionContextWindow hook with proper Zustand reactivity (subscribe to primitives)
- Add ContextWindowState to store with setContextWindow action
- Backend: propagate context_window data through orchestrator, watcher, and lifecycle events
- WebSocket handler extracts context_window from session.state_changed metadata
- Display positioned on left side of action bar, updates in real-time
* refactor: remove agent stream event WebSocket broadcasting
Agent stream events (message_chunk, tool_call, etc.) are now handled
internally by the lifecycle manager rather than being broadcast to
the frontend. Messages are accumulated and flushed as comments at
step boundaries.
* feat: session resumption with ACP session ID support
- Add useSessionResumption hook for automatic session recovery on page reload
- Fix ACPSessionID not being set on AgentInstance in Launch() and createInstance()
- Add task.session.status and task.session.resume WebSocket actions
- Fix shell terminal retry logic for resumed sessions
- Fix taskSessionState reading from Zustand store instead of local state
- Remove dead code: unused stream handling functions in lifecycle/manager.go
- Fix test mock interfaces (CleanupStaleInstanceByTaskID, NewManager signature)
- Add enhanced logging for session resumption debugging
- Simplify page-client.tsx state merging logic
* refactor: remove unused AgentController (dead code)
- Delete agent_controller.go - entirely unused duplicate of Manager methods
- Remove agentController field from Manager struct
- Remove AgentController initialization in NewManager
The AgentController duplicated StartAgentProcess, initializeACPSession, and
PromptAgent from Manager but was never called. All agent control operations
go through Manager's own methods.
* refactor: remove unused MemoryRepository (dead code)
- Delete memory.go - entire MemoryRepository implementation unused
(replaced by SQLite repository)
- Delete memory_test.go - tests for removed MemoryRepository
Found via 'deadcode' tool analysis.
* refactor: consolidate agentctl packages into server/client structure
Reorganize the confusing dual agentctl packages:
- internal/agentctl/* → internal/agentctl/server/
- internal/agent/agentctl/* → internal/agentctl/client/
Structure is now:
internal/agentctl/
├── client/ - HTTP client for talking to agentctl servers
│ ├── client.go
│ ├── standalone.go
│ ├── acp.go
│ └── launcher/
├── server/ - agentctl server implementation (runs in containers)
│ ├── api/
│ ├── adapter/
│ ├── acp/
│ ├── config/
│ ├── instance/
│ ├── process/
│ └── shell/
└── types/ - Shared types used by both client and server
Also consolidated shared types (GitStatusUpdate, FileInfo, etc.) from
process/types.go into the shared types/ package.
* refactor: rename AgentInstance to AgentExecution for clarity
Rename AgentInstance -> AgentExecution across the entire codebase to better
reflect what it represents: an agent actively working on a task, not just
a generic 'instance'.
Changes:
- AgentInstance struct -> AgentExecution
- InstanceStore -> ExecutionStore (new file: execution_store.go)
- RecoveredInstance -> RecoveredExecution
- All method names: GetInstance* -> GetExecution*, ListInstances -> ListExecutions, etc.
- All parameters: instanceID -> executionID
- All local variables: instance -> execution
- DTOs and JSON tags: agent_instance_id -> agent_execution_id
- Database columns: agent_instance_id -> agent_execution_id
Also consolidates duplicate prompt logic:
- Merge sendInitialPrompt and SendPrompt into single SendPrompt method
- Add validateStatus parameter to differentiate initial vs follow-up prompts
Also extracts ACP session management to session.go:
- Move initializeACPSession logic to SessionManager.InitializeAndPrompt
- Move PromptAgent logic to SessionManager.SendPrompt
- Manager now delegates to SessionManager for all prompt operations
Also removes duplicate event publishing:
- Remove 9 duplicate m.publish*() methods from manager.go
- Use existing EventPublisher methods via m.eventPublisher.Publish*()
Also extracts types to dedicated file:
- Move AgentExecution, LaunchRequest, PromptResult, etc. to types.go
Net reduction: ~600 lines removed from manager.go through deduplication
and better separation of concerns.
* fix(backend): Docker runtime now creates instance via ControlServer
The Docker runtime was incorrectly creating an agentctl.Client pointing
directly to port 9999 (the ControlServer port), then trying to call
instance-specific APIs like /api/v1/agent/configure which only exist
on per-instance servers.
Fixed by making Docker runtime follow the same flow as standalone mode:
- LaunchContainer now uses StandaloneCtl to create an instance via the
control API, then creates Client pointing to the instance port
- RecoverInstances queries the ControlServer to get the instance port
- Added waitForHealth helper to wait for agentctl to be ready
Also improved HTTP error handling in agentctl client:
- All client methods now check HTTP status codes before JSON decoding
- Better error messages include status code and response body
* fix: restore session resumption imports and variables
* fix: add sessionId prop back to TaskLayout
