* 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
* feat(agentctl): implement protocol adapter abstraction
- Add AgentAdapter interface for protocol-agnostic agent communication
- Create ACPAdapter implementation for ACP protocol (JSON-RPC over stdin/stdout)
- Add Protocol field to agent registry (AgentTypeConfig)
- Update process.Manager to use adapters instead of hardcoded ACP
- Update API layer to use adapter interface
- Pass protocol from registry to agentctl via CLI flag and env var
- Support protocol configuration in both Docker and standalone modes
This refactoring allows agentctl to support multiple protocols (ACP, REST, MCP)
via a pluggable adapter pattern. The backend remains protocol-agnostic,
always communicating with agentctl's HTTP API.
* refactor(agentctl): consolidate types and clean up code
- Create shared types package (internal/agentctl/types) for permission types
- Create shared protocol package (pkg/agent) for Protocol type
- Remove duplicate permission types from acp/client.go and adapter.go
- Make adapter the single source of truth for session ID
- Remove unused Command field from adapter.Config
- Remove passthrough wrapper function handleAdapterPermissionRequest
- Clean up extra empty lines in process/manager.go and acp_adapter.go
- Re-export permission types from adapter package for convenience
* fix(agent-session): rename AgentType to AgentProfileID for consistency
- Rename AgentSession.AgentType to AgentProfileID in models
- Update agent_sessions table schema column from agent_type to agent_profile_id
- Update all SQL queries in sqlite.go to use agent_profile_id
- Fix ToAPI() method to return agent_profile_id key
- Remove misleading comments in executor.go
Also adds comprehensive tests for affected areas:
- adapter package unit tests (SessionUpdate, PlanEntry, AgentInfo, Config)
- profile resolver unit tests with mock repository
- AgentSession CRUD tests in sqlite_test.go
* feat: replace agent_type with agent_profile_id
- Replace agent_type field with agent_profile_id across backend and frontend
- Add ProfileResolver interface and StoreProfileResolver implementation
- Update task creation/update to use agent_profile_id
- Change default agent runtime from docker to standalone
- Fix workspace state types to include all required fields
- Fix websocket handlers type mismatches for environments, executors, workspaces
- Update integration tests to use agent_profile_id
* feat: pass model as CLI argument to agents
- Add ModelFlag field to AgentTypeConfig for specifying the CLI flag
- Set ModelFlag to '--model' for all agents (auggie, claude, codex, gemini, opencode, copilot)
- Update launchStandalone to append model flag to agent command
- Update launchDocker/buildContainerConfig to append model flag to container command
- Model is passed when both agent supports ModelFlag and profile has Model configured
* fix: make WebSocket message handling async to prevent blocking
When a long-running handler like orchestrator.prompt was executing,
it blocked the ReadPump loop, preventing other requests (like
workspace.tree.get) from being processed until the handler completed.
Now each message is handled in its own goroutine, allowing concurrent
message handling so file tree requests work while the agent is working.
* feat: show task description as first message in chat
- Add 'Task' label with distinct styling (lighter background, border)
- Pass taskDescription from page to TaskChatPanel component
- Differentiate from regular user messages visually
* feat(web): add file browser with syntax-highlighted viewer
- Add file browser component in right panel to browse workspace files
- Open files in left panel tabs alongside Notes/Changes/Chat
- Color-coded dots for file types (TS, JS, Go, Python, etc.)
- Visual separator between main tabs and file tabs
- Folders sorted to top in file tree view
- LRU eviction for max 4 open file tabs
- Backend handlers for workspace file tree and content via WebSocket
* fix(web): refresh file tree on filesystem changes via fsnotify
- Subscribe to file change notifications from agentctl's fsnotify watcher
- Backend lifecycle manager now connects to file changes stream
- Publishes FileChangeNotified events to event bus
- WebSocket broadcasts workspace.file.changes to task subscribers
- Frontend file browser refreshes tree when changes detected
* perf(agentctl): use fsnotify instead of polling for git status
- Replace 2-second polling with fsnotify-triggered updates
- Add debouncing (300ms) to batch rapid file changes
- Git status updates now triggered by actual filesystem changes
- More efficient and responsive than periodic polling
* refactor(agentctl): consolidate fs events into single debounced trigger
- Single fsChangeTrigger channel for all filesystem events
- After 300ms debounce: update git status, files, and notify subscribers
- Removed per-file notifications in favor of single 'refresh' event
- Simpler and more efficient than separate triggers
* refactor(agentctl): simplify file API - use HTTP for tree/content
- Remove unused filesConn, fileTreeConn, fileContentConn from Client struct
- Convert RequestFileTree and RequestFileContent from WebSocket to HTTP GET
- Remove StreamFiles and CloseFilesStream (redundant with file changes stream)
- Keep only fileChangesConn for the debounced refresh notification
HTTP is simpler than WebSocket for request/response patterns.
* feat(web): switch to CodeMirror for file viewer
- Replace react-syntax-highlighter with @uiw/react-codemirror
- Add language extensions for JS/TS, Python, Go, Rust, Java, C++, CSS, HTML, JSON, Markdown, YAML
- Use VS Code dark theme for consistent look
- Enable code folding and read-only mode
- Better performance and features than syntax highlighter
* refactor: consolidate duplicated types and extract shared constants
- Re-export file types from process package in agentctl/client.go instead of duplicating
- Move OpenFileTab type to lib/types/backend.ts (shared by file-browser and page-client)
- Extract FILE_EXTENSION_COLORS constant for file type color indicators
- Remove console.log statement and unused imports in file-browser.tsx
- Add 'refresh' operation to FileChangeNotificationPayload type
* refactor(agentctl): move Close() method from acp.go to client.go
Close() is a general client cleanup method that closes all streams
(ACP, permissions, git status, file changes). It belongs in client.go
since acp.go should only contain ACP-specific communication logic.
* fix(web): remove unused cn import in file-browser
* refactor(agentctl): consolidate duplicated types into process/types.go
- Create process/types.go with all workspace-related types
- Remove duplicate GitStatusUpdate, FileInfo from workspace_tracker.go
- Remove duplicate GitStatusUpdate, FileInfo from api/workspace.go
- Re-export all types from agent/agentctl/client.go for convenience
Types are now defined once and imported everywhere.
* chore: remove package-lock.json, add to .gitignore
Project uses pnpm (pnpm-lock.yaml), not npm.
* fix(orchestrator): probe agent before returning stale execution state
When checking task.execution, the backend now probes the actual agent:
- For tracked instances: health check via agentctl
- For Docker: verify container is running
If the agent is not running but DB says 'running', the session is
marked as stopped and false is returned. This fixes the UI showing
agents as running after backend restart when they're actually dead.
Changes:
- Add IsAgentRunningForTask to AgentManagerClient interface
- Add IsContainerRunning to docker client
- Update GetExecution to verify agent is actually running
- Clean up stale sessions in database when agent not found
* fix(orchestrator): use agentctl status to verify agent is running
Simplified approach - probe agentctl's /api/v1/status endpoint to check
if agent process is running. Same check for both Docker and standalone.
- Add IsAgentRunning() helper to StatusResponse
- Simplify IsAgentRunningForTask to just use agentctl.GetStatus()
* fix(orchestrator): also verify agent running for in-memory executions
The previous fix only checked agent status when loading from DB. But if
an execution is cached in memory and the agent process stops (while
agentctl stays running), the stale state was still returned.
Now both paths verify the agent is actually running by probing agentctl.
If agent stopped, clean up in-memory state and update DB session.
* chore(web): remove unused react-syntax-highlighter
Switched to CodeMirror for code viewing, no longer needed.
* fix(tests): add IsAgentRunningForTask to mock agent managers
Add the new interface method to test mocks:
- mockAgentManager in scheduler_test.go
- SimulatedAgentManagerClient in orchestrator_test.go
