From bc77da30f6b8ac8cd3fc328a02a0472a81e036ef Mon Sep 17 00:00:00 2001 From: Shane Neuville Date: Fri, 6 Feb 2026 11:52:00 -0600 Subject: [PATCH] Persistent sessions, streaming fixes, stop button, settings page MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Features: - Persistent Copilot sessions that survive app restarts (headless TCP server mode) - ServerManager: spawn/detect/stop detached copilot --headless servers with PID tracking - Settings page: toggle between Embedded and Persistent connection modes - Stop button to abort running chat responses (SDK AbortAsync) - Session reconnection with 'πŸ”„ Session reconnected' indicator - Auto-restore previous sessions on app launch Streaming & rendering fixes: - Fix message duplication: deduplicate AssistantMessageEvent by MessageId (SDK fires events N times for sessions resumed N times) - Fix per-turn delta tracking: HasReceivedDeltasThisTurn flag prevents double-append when both delta and full message events fire - Fix streaming content lifecycle: accumulate across turns, clear only when full response completes (no more vanishing messages) - Remove tool call/reasoning cards from chat history (caused hundreds of thin green lines filling the screen). Show single inline tool indicator for currently running tool instead - Add explicit color: white to assistant message text and markdown body (fixes invisible text from Bootstrap color override on dark background) UI improvements: - System message type and styling for reconnection indicators - Enter key fix: JS interop prevents default on Enter without Shift - Connection mode indicator in sidebar (Persistent/Embedded) - Settings tab in sidebar navigation New files: - Models/ConnectionSettings.cs - Connection mode enum and settings persistence - Services/ServerManager.cs - Server lifecycle management with PID files - Components/Pages/Settings.razor - Connection settings UI - README.md - Comprehensive project documentation --- Components/Layout/SessionSidebar.razor | 10 +- Components/Pages/Dashboard.razor | 13 +- Components/Pages/Home.razor | 224 ++++++----------- Components/Pages/Home.razor.css | 36 +++ Components/Pages/Settings.razor | 162 ++++++++++++ Components/Pages/Settings.razor.css | 332 +++++++++++++++++++++++++ MauiProgram.cs | 30 +++ Models/ChatMessage.cs | 6 +- Models/ConnectionSettings.cs | 51 ++++ README.md | 270 ++++++++++++++++++++ Services/CopilotService.cs | 223 ++++++++++++++--- Services/ServerManager.cs | 211 ++++++++++++++++ wwwroot/index.html | 10 + 13 files changed, 1389 insertions(+), 189 deletions(-) create mode 100644 Components/Pages/Settings.razor create mode 100644 Components/Pages/Settings.razor.css create mode 100644 Models/ConnectionSettings.cs create mode 100644 README.md create mode 100644 Services/ServerManager.cs diff --git a/Components/Layout/SessionSidebar.razor b/Components/Layout/SessionSidebar.razor index 10f81d96a3..241b5fbf10 100644 --- a/Components/Layout/SessionSidebar.razor +++ b/Components/Layout/SessionSidebar.razor @@ -8,11 +8,19 @@

AutoPilot provides a native GUI for creating, orchestrating, and interacting with parallel Copilot agent sessions β€” acting as a multi-agent control plane. + +## What Problem It Solves + +Working with GitHub Copilot CLI is powerful, but limited to a single terminal session at a time. AutoPilot lets you: + +- Run **multiple Copilot sessions in parallel**, each with its own model, working directory, and conversation history +- **Orchestrate agents** from a dashboard β€” broadcast the same prompt to all sessions at once +- **Resume sessions** across app restarts β€” sessions persist to disk and can be picked up later +- **Choose connection modes** β€” from simple embedded stdio to a persistent server that outlives the app + +## Features + +### Multi-Session Management +Create named sessions with different models and working directories. Sessions appear in a sidebar and can be switched between instantly. Each session maintains its own conversation history and processing state. + +### Chat Interface +Full chat UI with streaming responses, real-time activity logging, Markdown rendering (code blocks, inline code, bold), and auto-scrolling. Shows typing indicators and tool execution status as Copilot works. + +### Session Orchestrator Dashboard +A grid view of all active sessions showing their last messages, streaming output, and processing state. Includes per-card message input and a **Broadcast to All** feature to send the same prompt to every idle session simultaneously. + +### Real-Time Activity Log +During processing, the UI displays a live activity feed showing Copilot's intent (`πŸ’­ Thinking...`), tool calls (`πŸ”§ Running bash...`), and completion status (`βœ… Tool completed`). This gives full visibility into multi-step agent workflows. + +### Session Persistence & Resume +- **Active sessions** are saved to `~/.copilot/autopilot-active-sessions.json` and automatically restored on app relaunch +- **All Copilot sessions** persisted in `~/.copilot/session-state/` can be browsed and resumed from the sidebar's "Saved Sessions" panel +- Conversation history is reconstructed from the SDK's `events.jsonl` files on resume +- Sessions display their first user message as a title for easy identification + +### UI State Persistence +The app remembers which page you were on (Chat, Dashboard, or Settings) and which session was active, restoring both on relaunch via `~/.copilot/autopilot-ui-state.json`. + +### Auto-Reconnect +If a session disconnects during a prompt, the service automatically attempts to resume the session by its GUID and retry the message. + +### Per-Session Working Directory +Each session can target a different directory on disk. A native macOS folder picker (via `UIDocumentPickerViewController`) is available for browsing. + +### Model Selection +Sessions can be created with any of the supported models: +`claude-opus-4.6`, `claude-sonnet-4.5`, `claude-sonnet-4`, `claude-haiku-4.5`, `gpt-5.2`, `gpt-5.1`, `gpt-5`, `gpt-5-mini`, `gemini-3-pro-preview` + +### System Instructions +Automatically loads project-level instructions from `.github/copilot-instructions.md` and appends them to every session's system message. When a session targets the AutoPilot project directory, it also injects build/relaunch instructions. + +### Crash Logging +Unhandled exceptions and unobserved task failures are caught globally and written to `~/.copilot/autopilot-crash.log`. + +## Connection Modes + +AutoPilot supports three transport modes, configurable from the Settings page: + +| Mode | Transport | Lifecycle | Best For | +|------|-----------|-----------|----------| +| **Embedded** (default) | stdio | Dies with app | Simple single-machine use | +| **TCP Server** | SDK-managed TCP | Dies with app | More stable long sessions | +| **Persistent Server** | Detached TCP server | Survives app restarts | Session continuity across relaunches | + +### Embedded (stdio) +The SDK spawns a Copilot CLI process and communicates via stdin/stdout. Simplest setup β€” no port configuration needed. The process terminates when the app closes. + +### TCP Server +The SDK spawns and manages a Copilot CLI process using TCP transport internally. More stable for long-running sessions, but the server still dies when the app exits. + +### Persistent Server +The app spawns a **detached** Copilot CLI server process (`copilot --headless --port 4321`) that runs independently. The server's PID and port are tracked in `~/.copilot/autopilot-server.pid`. On relaunch, the app detects the existing server and reconnects. You can start/stop the server from the Settings page. + +## Architecture + +``` +β”Œβ”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β” +β”‚ AutoPilot.App β”‚ +β”‚ (.NET MAUI Blazor Hybrid) β”‚ +β”‚ β”‚ +β”‚ β”Œβ”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β” β”Œβ”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β” β”Œβ”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β” β”‚ +β”‚ β”‚ SessionSidebarβ”‚ β”‚ Home.razorβ”‚ β”‚ Dashboard.razorβ”‚ β”‚ +β”‚ β”‚ (create/ β”‚ β”‚ (chat UI) β”‚ β”‚ (orchestrator) β”‚ β”‚ +β”‚ β”‚ resume) β”‚ β”‚ β”‚ β”‚ β”‚ β”‚ +β”‚ β””β”€β”€β”€β”€β”€β”€β”¬β”€β”€β”€β”€β”€β”€β”€β”˜ β””β”€β”€β”€β”€β”€β”¬β”€β”€β”€β”€β”€β”€β”˜ β””β”€β”€β”€β”€β”€β”€β”€β”¬β”€β”€β”€β”€β”€β”€β”€β”€β”˜ β”‚ +β”‚ β”‚ β”‚ β”‚ β”‚ +β”‚ β””β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”Όβ”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”˜ β”‚ +β”‚ β”‚ β”‚ +β”‚ β”Œβ”€β”€β”€β”€β”€β”€β”€β”€β”€β–Όβ”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β” β”‚ +β”‚ β”‚ CopilotService β”‚ (singleton) β”‚ +β”‚ β”‚ β”Œβ”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β” β”‚ β”‚ +β”‚ β”‚ β”‚ SessionState β”‚ β”‚ ConcurrentDict β”‚ +β”‚ β”‚ β”‚ β”œβ”€ Session β”‚ β”‚ of named sessions β”‚ +β”‚ β”‚ β”‚ β”œβ”€ Info β”‚ β”‚ β”‚ +β”‚ β”‚ β”‚ └─ Response β”‚ β”‚ β”‚ +β”‚ β”‚ β””β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”˜ β”‚ β”‚ +β”‚ β””β”€β”€β”€β”€β”€β”€β”€β”€β”€β”¬β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”˜ β”‚ +β”‚ β”‚ β”‚ +β”‚ β”Œβ”€β”€β”€β”€β”€β”€β”€β”€β”€β–Όβ”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β” β”‚ +β”‚ β”‚ CopilotClient β”‚ (GitHub.Copilot.SDK)β”‚ +β”‚ β””β”€β”€β”€β”€β”€β”€β”€β”€β”€β”¬β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”˜ β”‚ +β”‚ β”‚ β”‚ +β”‚ β”Œβ”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”Όβ”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β” β”‚ +β”‚ β”‚ stdio β”‚ TCP β”‚ TCP (remote)β”‚ +β”‚ β–Ό β–Ό β–Ό β”‚ +β”‚ β”Œβ”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β” β”Œβ”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β” β”Œβ”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β” β”‚ +β”‚ β”‚ copilot β”‚ β”‚ copilot β”‚ β”‚ Persistent β”‚ β”‚ +β”‚ β”‚ (child) β”‚ β”‚ (child) β”‚ β”‚ Server β”‚ β”‚ +β”‚ β””β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”˜ β””β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”˜ β”‚ (detached) β”‚ β”‚ +β”‚ β””β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”˜ β”‚ +β”‚ β–² β”‚ +β”‚ β”Œβ”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”˜ β”‚ +β”‚ β”Œβ”€β”€β”€β”€β”€β”€β”΄β”€β”€β”€β”€β”€β”€β”€β”€β” β”‚ +β”‚ β”‚ ServerManager β”‚ (PID file tracking) β”‚ +β”‚ β””β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”˜ β”‚ +β””β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”˜ +``` + +### Key Components + +- **`CopilotService`** β€” Singleton service wrapping the Copilot SDK.

The SDK spawns/connects to Copilot and returns a `CopilotSession`. + +2. **Chat**: User types a message β†’ `SendPromptAsync` adds it to history, calls `session.SendAsync`, and awaits a `TaskCompletionSource` that completes when `SessionIdleEvent` fires. Streaming deltas are emitted to the UI in real time. + +3. **Persist**: After every session create/close, the active session list is written to disk. The Copilot SDK independently persists session state in `~/.copilot/session-state//`. + +4. **Resume**: On relaunch, `RestorePreviousSessionsAsync` reads the active sessions file and calls `ResumeSessionAsync` for each. Conversation history is reconstructed from the SDK's `events.jsonl`. Users can also manually resume any saved session from the sidebar. + +5. **Close**: `CloseSessionAsync` disposes the `CopilotSession`, removes it from the dictionary, and updates the active sessions file. + +### Event Handling + +All SDK events are received on background threads. `CopilotService` captures the UI `SynchronizationContext` during initialization and uses `_syncContext.Post` to marshal event callbacks to the Blazor UI thread, where components call `StateHasChanged()` to re-render. + +### Reconnect on Failure + +If `SendAsync` throws (e.g., the underlying process died), the service attempts to resume the session by its persisted GUID and retry the prompt once. This is transparent to the user β€” they see a "πŸ”„ Reconnecting session..." activity indicator. + +### Persistent Server Detection + +On startup in Persistent mode, `ServerManager.DetectExistingServer()` reads `autopilot-server.pid`, checks if the process is alive via TCP connect, and reuses it if available. Stale PID files are cleaned up automatically. + +## NuGet Dependencies + +| Package | Version | Purpose | +|---------|---------|---------| +| `GitHub.Copilot.SDK` | 0.1.22 | Copilot CLI client (ACP protocol) | +| `Microsoft.Maui.Controls` | (MAUI SDK) | .NET MAUI framework | +| `Microsoft.AspNetCore.Components.WebView.Maui` | (MAUI SDK) | Blazor WebView for MAUI | +| `Microsoft.Extensions.Logging.Debug` | 10.0.0 | Debug logging | + +> **Note**: The csproj includes `` to prevent the linker from stripping SDK event types needed for runtime pattern matching.
