OpenCode-Style Session Management Implementation Plan

For Claude: REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.

Goal: Transform Sessions view from duplicate command interface into a read-only project history browser that seamlessly integrates with Chat view.

Architecture:

• Backend: Add project filtering to sessions API, fix running status detection
• Frontend: Remove duplicate command input from Sessions view, add "Continue in Chat" action, implement read-only detail view
• Integration: Sessions view → Chat view switching with pending session detection

Tech Stack: Node.js, Express.js, WebSocket, Vanilla JavaScript, SQLite

---

Task 1: Backend - Add Project Filtering to Sessions API

Files:

• Modify: server.js:1029 (GET /claude/api/claude/sessions endpoint)

Step 1: Read current sessions endpoint implementation

Run: grep -n "app.get.*claude/sessions" server.js -A 20 Expected: Shows current implementation without project filtering

Step 2: Add project query parameter filtering

Find the sessions endpoint around line 1029 in server.js. Replace the endpoint with:

// GET /claude/api/claude/sessions?project=/encoded/path
app.get('/claude/api/claude/sessions', requireAuth, async (req, res) => {
  try {
    const { project } = req.query;

    let activeSessions = claudeService.listSessions();
    let historicalSessions = claudeService.loadHistoricalSessions();

    // PROJECT FILTERING
    if (project) {
      const projectPath = decodeURIComponent(project);
      console.log('[SESSIONS] Filtering by project path:', projectPath);

      activeSessions = activeSessions.filter(s => {
        const sessionPath = s.workingDir || '';
        return sessionPath.startsWith(projectPath) || sessionPath === projectPath;
      });

      historicalSessions = historicalSessions.filter(s => {
        const sessionPath = s.workingDir || '';
        return sessionPath.startsWith(projectPath) || sessionPath === projectPath;
      });

      console.log('[SESSIONS] Filtered to', activeSessions.length, 'active,', historicalSessions.length, 'historical');
    }

    res.json({
      active: activeSessions,
      historical: historicalSessions
    });
  } catch (error) {
    console.error('[SESSIONS] Error:', error);
    res.status(500).json({ error: error.message });
  }
});

Step 3: Test the endpoint manually

Run: curl -s "http://localhost:3010/claude/api/claude/sessions?project=%2Fhome%2Furoma" -H "Cookie: connect.sid=YOUR_SESSION_COOKIE" | jq '.active | length' Expected: Returns count of sessions from /home/uroma path

Step 4: Commit

git add server.js
git commit -m "feat(sessions): add project filtering to sessions API

Adds ?project query parameter to filter sessions by working directory.
This ensures Sessions view only shows relevant sessions for current project.

- Decode project parameter from URL
- Filter both active and historical sessions
- Add logging for debugging

Task 2: Backend - Fix Session Status Detection

Files:

• Modify: services/claude-service.js:446 (listSessions method)

Step 1: Read current listSessions implementation

Run: grep -n "listSessions()" services/claude-service.js -A 15 Expected: Shows current implementation that marks all sessions as "running"

Step 2: Update status detection logic

Find the listSessions() method around line 446. Replace the status logic:

listSessions() {
  return Array.from(this.sessions.values()).map(session => {
    const metadata = this.calculateSessionMetadata(session);

    // FIX: Only mark as running if process is actually alive
    const isRunning = session.status === 'running' &&
                      session.process &&
                      !session.process.killed;

    return {
      id: session.id,
      pid: session.pid,
      workingDir: session.workingDir,
      status: isRunning ? 'running' : 'stopped',
      createdAt: session.createdAt,
      lastActivity: session.lastActivity,
      metadata: session.metadata,
      ...metadata
    };
  });
}

Step 3: Test status detection

Run: curl -s "http://localhost:3010/claude/api/claude/sessions" -H "Cookie: connect.sid=YOUR_SESSION_COOKIE" | jq '.active[0].status' Expected: Returns "running" only if process alive, "stopped" otherwise

Step 4: Commit

git add services/claude-service.js
git commit -m "fix(sessions): correctly detect running session status

Only marks sessions as 'running' if the process is actually alive.
Historical sessions loaded from disk now correctly show as 'stopped'.

- Check process.killed flag
- Verify process exists before marking as running
- Fixes misleading status badges in UI

Task 3: Frontend - Update loadSessions() with Project Filtering

Files:

• Modify: public/claude-ide/ide.js:348 (loadSessions function)

Step 1: Read current loadSessions implementation

Run: grep -n "async function loadSessions()" public/claude-ide/ide.js -A 30 Expected: Shows current implementation that loads all sessions

Step 2: Replace loadSessions() with filtered version

Find the loadSessions() function around line 348. Replace entire function:

async function loadSessions() {
    const sessionsListEl = document.getElementById('sessions-list');

    try {
        // Get current project from URL
        const urlParams = new URLSearchParams(window.location.search);
        const projectPath = urlParams.get('project');

        // Build API URL with project filter
        let apiUrl = '/claude/api/claude/sessions';
        if (projectPath) {
            apiUrl += `?project=${encodeURIComponent(projectPath)}`;
            console.log('[Sessions] Loading sessions for project:', projectPath);
        }

        // Show loading state
        sessionsListEl.innerHTML = '<div class="loading">Loading sessions...</div>';

        const res = await fetch(apiUrl);

        // Handle HTTP errors
        if (!res.ok) {
            if (res.status === 401) {
                sessionsListEl.innerHTML = `
                    <div class="error-state">
                        <p>⚠️ Session expired</p>
                        <button class="btn-primary" onclick="location.reload()">Login Again</button>
                    </div>
                `;
                return;
            }
            throw new Error(`HTTP ${res.status}: ${res.statusText}`);
        }

        const data = await res.json();

        // Handle API errors
        if (data.error) {
            throw new Error(data.error);
        }

        const allSessions = [
            ...(data.active || []).map(s => ({...s, type: 'active'})),
            ...(data.historical || []).map(s => ({...s, type: 'historical'}))
        ];

        // Sort by last activity (newest first)
        allSessions.sort((a, b) => {
            const dateA = new Date(a.lastActivity || a.createdAt || a.created_at);
            const dateB = new Date(b.lastActivity || b.createdAt || b.created_at);
            return dateB - dateA;
        });

        // Empty state
        if (allSessions.length === 0) {
            const projectName = projectPath ? projectPath.split('/').pop() : 'this project';
            sessionsListEl.innerHTML = `
                <div class="empty-state">
                    <div class="empty-icon">📂</div>
                    <p>No sessions found for <strong>${escapeHtml(projectName)}</strong></p>
                    <button class="btn-primary" onclick="startNewChat()">Create New Session</button>
                </div>
            `;
            return;
        }

        // Render session list
        sessionsListEl.innerHTML = allSessions.map(session => {
            const isRunning = session.status === 'running' && session.type === 'active';
            const relativeTime = getRelativeTime(session);
            const messageCount = session.messageCount || session.metadata?.messageCount || 0;

            return `
                <div class="session-item ${session.type}" onclick="viewSessionDetails('${session.id}')">
                    <div class="session-header">
                        <div class="session-info">
                            <span class="session-id">${session.id.substring(0, 12)}...</span>
                            <span class="session-status ${isRunning ? 'running' : 'stopped'}">
                                ${isRunning ? '🟢 Running' : '⏸️ ' + (session.type === 'historical' ? 'Historical' : 'Stopped')}
                            </span>
                        </div>
                        <div class="session-time">${relativeTime}</div>
                    </div>
                    <div class="session-meta">
                        <div class="session-path">📁 ${escapeHtml(session.workingDir)}</div>
                        <div class="session-stats">
                            <span>💬 ${messageCount} messages</span>
                        </div>
                    </div>
                </div>
            `;
        }).join('');

    } catch (error) {
        console.error('[loadSessions] Error:', error);
        sessionsListEl.innerHTML = `
            <div class="error-state">
                <div class="error-icon">⚠️</div>
                <p>Failed to load sessions</p>
                <p class="error-message">${escapeHtml(error.message)}</p>
                <button class="btn-secondary" onclick="loadSessions()">Try Again</button>
            </div>
        `;
    }
}

Step 3: Add helper functions

Add these helper functions after loadSessions():

function getRelativeTime(session) {
    const date = new Date(session.lastActivity || session.createdAt || session.created_at);
    const now = new Date();
    const diffMins = Math.floor((now - date) / 60000);

    if (diffMins < 1) return 'Just now';
    if (diffMins < 60) return `${diffMins}m ago`;
    if (diffMins < 1440) return `${Math.floor(diffMins/60)}h ago`;
    return `${Math.floor(diffMins/1440)}d ago`;
}

function escapeHtml(text) {
    const div = document.createElement('div');
    div.textContent = text;
    return div.innerHTML;
}

Step 4: Test in browser

Open: http://localhost:3010/claude/ide?project=%2Fhome%2Furoma Click: Sessions tab Expected: Only shows sessions from /home/uroma, sorted by last activity

Step 5: Commit

git add public/claude-ide/ide.js
git commit -m "feat(sessions): add project filtering and improved UI

Sessions view now filters by current project from URL parameter.
Adds sorting, relative timestamps, and better error handling.

- Extract project from ?project query parameter
- Filter sessions by working directory
- Sort by last activity (newest first)
- Add relative time display (5m ago, 2h ago)
- Add empty state with 'Create New Session' button
- Add comprehensive error states
- XSS prevention with escapeHtml()

Task 4: Frontend - Replace viewSession() with viewSessionDetails()

Files:

• Modify: public/claude-ide/ide.js:380 (viewSession function)

Step 1: Read current viewSession implementation

Run: grep -n "async function viewSession" public/claude-ide/ide.js -A 50 Expected: Shows current implementation with duplicate command input

Step 2: Replace viewSession() with viewSessionDetails()

Find the viewSession() function around line 380. Replace entire function:

            </div>
        `;
    }
}

Step 3: Update session list onclick handler

In loadSessions(), change the onclick:

// Before: onclick="viewSession('${session.id}')"
// After:
onclick="viewSessionDetails('${session.id}')"

Step 4: Test in browser

Open: http://localhost:3010/claude/ide?project=%2Fhome%2Furoma Click: Sessions tab → click on a session Expected: Shows detail view with action buttons, NO command input

Step 5: Commit

git add public/claude-ide/ide.js
git commit -m "feat(sessions): transform to read-only detail view

Removes duplicate command input from Sessions view.
Transforms into history browser with 'Continue in Chat' action.

- Replace viewSession() with viewSessionDetails()
- Remove duplicate command input field
- Add action buttons: Continue, Duplicate, Terminate
- Show session metadata (created, last activity, messages)
- Show token usage progress bar
- Show output preview (first 50 entries)
- Add comprehensive error states (404, 500)
- Proper status badges (running vs stopped)

Task 5: Frontend - Add Session Action Functions

Files:

• Modify: public/claude-ide/ide.js (add after viewSessionDetails)

Step 1: Add continueSessionInChat() function

async function continueSessionInChat(sessionId) {
    console.log('[Sessions] Continuing session in Chat:', sessionId);

    try {
        showLoadingOverlay('Loading session...');

        const res = await fetch(`/claude/api/claude/sessions/${sessionId}`);
        if (!res.ok) {
            throw new Error(`HTTP ${res.status}`);
        }

        const data = await res.json();
        if (!data.session) {
            throw new Error('Session not found');
        }

        const session = data.session;

        // Check if session is runnable
        if (session.status === 'terminated' || session.status === 'stopped') {
            hideLoadingOverlay();

            if (confirm('This session has ended. Do you want to create a new session with the same working directory?')) {
                await duplicateSession(sessionId);
            }
            return;
        }

        // Store pending session and switch views
        window.pendingSessionId = sessionId;
        window.pendingSessionData = session;

        switchView('chat');

    } catch (error) {
        console.error('[continueSessionInChat] Error:', error);
        hideLoadingOverlay();
        showToast('❌ Failed to load session: ' + error.message, 'error');
    }
}

Step 2: Add duplicateSession() function

async function duplicateSession(sessionId) {
    try {
        const res = await fetch(`/claude/api/claude/sessions/${sessionId}`);
        const data = await res.json();

        if (!data.session) {
            throw new Error('Session not found');
        }

        const workingDir = data.session.workingDir;
        const projectName = workingDir.split('/').pop();

        showLoadingOverlay('Duplicating session...');

        const createRes = await fetch('/claude/api/claude/sessions', {
            method: 'POST',
            headers: { 'Content-Type': 'application/json' },
            body: JSON.stringify({
                workingDir,
                metadata: {
                    type: 'chat',
                    source: 'web-ide',
                    project: projectName,
                    duplicatedFrom: sessionId
                }
            })
        });

        if (!createRes.ok) {
            throw new Error(`HTTP ${createRes.status}`);
        }

        const createData = await createRes.json();

        hideLoadingOverlay();
        showToast('✅ Session duplicated!', 'success');

        loadSessions();

        setTimeout(() => {
            if (confirm('Start chatting in the duplicated session?')) {
                continueSessionInChat(createData.session.id);
            }
        }, 500);

    } catch (error) {
        console.error('[duplicateSession] Error:', error);
        hideLoadingOverlay();
        showToast('Failed to duplicate session: ' + error.message, 'error');
    }
}

Step 3: Add terminateSession() function

async function terminateSession(sessionId) {
    if (!confirm('Are you sure you want to terminate this session?')) {
        return;
    }

    try {
        showLoadingOverlay('Terminating session...');

        const res = await fetch(`/claude/api/claude/sessions/${sessionId}`, {
            method: 'DELETE'
        });

        if (!res.ok) {
            throw new Error(`HTTP ${res.status}`);
        }

        hideLoadingOverlay();
        showToast('✅ Session terminated', 'success');

        loadSessions();

        if (currentSession && currentSession.id === sessionId) {
            document.getElementById('session-detail').innerHTML = `
                <div class="placeholder">
                    <h2>Session Terminated</h2>
                    <p>Select another session from the sidebar</p>
                </div>
            `;
            currentSession = null;
        }

    } catch (error) {
        console.error('[terminateSession] Error:', error);
        hideLoadingOverlay();
        showToast('Failed to terminate session: ' + error.message, 'error');
    }
}

Step 4: Test actions in browser

Open: http://localhost:3010/claude/ide?project=%2Fhome%2Furoma Click: Sessions tab → click session → click "Continue in Chat" Expected: Switches to Chat view, session loads

Step 5: Commit

git add public/claude-ide/ide.js
git commit -m "feat(sessions): add session action functions

Add Continue, Duplicate, and Terminate actions for sessions.
Implements seamless Sessions → Chat view switching.

- continueSessionInChat(): Switch to Chat view with session
- duplicateSession(): Create new session with same workingDir
- terminateSession(): Stop running session with confirmation
- Store pending session for Chat view to pick up
- Handle terminated sessions gracefully

Task 6: Frontend - Chat View Integration

Files:

• Modify: public/claude-ide/chat-functions.js (update loadChatView)

Step 1: Read current loadChatView implementation

Run: grep -n "async function loadChatView()" public/claude-ide/chat-functions.js -A 5 Expected: Shows current loadChatView function

Step 2: Add pending session detection

At the START of loadChatView(), add this logic:

async function loadChatView() {
    console.log('[loadChatView] Loading Chat view');

    // Check if there's a pending session from Sessions view
    if (window.pendingSessionId) {
        console.log('[loadChatView] Detected pending session:', window.pendingSessionId);

        const sessionId = window.pendingSessionId;
        const sessionData = window.pendingSessionData;

        // Clear pending session (consume it)
        window.pendingSessionId = null;
        window.pendingSessionData = null;

        // Load the session
        await loadSessionIntoChat(sessionId, sessionData);
        return;
    }

    // ... rest of existing loadChatView() logic continues unchanged

Step 3: Add loadSessionIntoChat() function

Add this new function after loadChatView():

async function loadSessionIntoChat(sessionId, sessionData = null) {
    try {
        appendSystemMessage('📂 Loading session...');

        // If no session data provided, fetch it
        if (!sessionData) {
            const res = await fetch(`/claude/api/claude/sessions/${sessionId}`);
            if (!res.ok) {
                throw new Error(`HTTP ${res.status}`);
            }
            const data = await res.json();
            sessionData = data.session;
        }

        if (!sessionData) {
            throw new Error('Session not found');
        }

        // Set session IDs
        attachedSessionId = sessionId;
        chatSessionId = sessionId;

        // Update UI
        document.getElementById('current-session-id').textContent = sessionId;

        // Clear chat display
        clearChatDisplay();

        // Load session messages (both user and assistant)
        if (sessionData.outputBuffer && sessionData.outputBuffer.length > 0) {
            sessionData.outputBuffer.forEach(entry => {
                if (entry.role) {
                    appendMessage(entry.role, entry.content, false);
                } else {
                    // Legacy format - default to assistant
                    appendMessage('assistant', entry.content, false);
                }
            });
        }

        // Show success message
        const isRunning = sessionData.status === 'running';
        const statusText = isRunning ? 'Active session' : 'Historical session';
        appendSystemMessage(`✅ Loaded ${statusText} from ${new Date(sessionData.createdAt).toLocaleString()}`);

        if (!isRunning) {
            appendSystemMessage('ℹ️ This is a historical session. Messages are read-only.');
        }

        // Update chat history sidebar to highlight this session
        if (typeof loadChatHistory === 'function') {
            loadChatHistory();
        }

        // Subscribe to session for live updates (if running)
        if (isRunning) {
            subscribeToSession(sessionId);
        }

        // Focus input for active sessions
        if (isRunning) {
            setTimeout(() => {
                const input = document.getElementById('chat-input');
                if (input) input.focus();
            }, 100);
        }

    } catch (error) {
        console.error('[loadSessionIntoChat] Error:', error);
        appendSystemMessage('❌ Failed to load session: ' + error.message);
    }
}

Step 4: Test full workflow

Open: http://localhost:3010/claude/ide?project=%2Fhome%2Furoma Click: Sessions tab → click session → "Continue in Chat" Expected: Switches to Chat view, session loads with all messages

Step 5: Commit

git add public/claude-ide/chat-functions.js
git commit -m "feat(chat): add pending session detection

Detects and loads sessions continued from Sessions view.
Seamless integration between history browser and workspace.

- Check window.pendingSessionId on loadChatView()
- Add loadSessionIntoChat() to restore session messages
- Handle both active and historical sessions
- Subscribe to live updates for running sessions
- Update chat history sidebar to highlight active session
- Restore user and assistant messages correctly
