ULPI API token
Coordination subscription active

Setup Steps:

Install ULPI Package

npm install -g ulpi

Run Guided Setup

ulpi setup

Select “Claude Code” when prompted.

╚══════════════════════════════════════════╝

Configuration

Claude Code hooks are configured in ~/.claude-code/hooks/ulpi.config.json:

{
  "apiToken": "ulpi_sk_...",
  "apiUrl": "https://api.ulpi.io",
  "hooks": {
    "sessionStart": { "enabled": true },
    "preEdit": { "enabled": true, "autoReserve": true },
    "postEdit": { "enabled": true },
    "preCompact": { "enabled": true, "createSnapshot": true },
    "userPrompt": { "enabled": true },
    "stop": { "enabled": true },
    "sessionEnd": { "enabled": true },
    "subagentStop": { "enabled": true }
  }
}

Performance

Claude Code has the best hook performance:

Hook	Latency	Notes
session-start	~130ms	Fastest (native integration)
pre-edit	~100ms	Fastest (local caching)
pre-compact	~180ms	Native compaction API
Overall	~115ms avg	Best-in-class

Troubleshooting

Hooks not showing on session start

Solution:

Check config exists: ls ~/.claude-code/hooks/ulpi.config.json
Verify API token: ulpi auth verify
Check logs: claude-code --debug-hooks
Reinstall: ulpi setup --force

Pre-compact hook not firing

Solution: Claude Code uses a different compaction trigger. Enable debug logging:

{ "debug": true, "hooks": { "preCompact": { "verbose": true } } }

Watch logs for compaction events.

Cursor Setup

Installation

Prerequisites:

Cursor installed (version ≥ 0.30.0)
ULPI API token
Coordination subscription active

Setup Steps:

Install ULPI Package

npm install -g ulpi

Run Guided Setup

ulpi setup

Select “Cursor” when prompted.

Reload Cursor Window

In Cursor:

Press Cmd+Shift+P (Mac) or Ctrl+Shift+P (Windows/Linux)
Type “Developer: Reload Window”
Press Enter

Verify Hooks Active

Open Cursor composer and check bottom-right status bar:

ULPI Hooks: 8/8 active ✓

Configuration

Cursor hooks are configured in ~/.cursor/hooks/ulpi.config.json:

{
  "apiToken": "ulpi_sk_...",
  "apiUrl": "https://api.ulpi.io",
  "hooks": {
    // Same as Claude Code config
  },
  "cursor": {
    // Cursor-specific settings
    "composerIntegration": true,  // Show hooks in composer
    "statusBarIcon": true          // Show status in status bar
  }
}

Cursor-Specific Features

Composer Integration: When using Cursor’s composer mode, hooks integrate seamlessly:

┌─────────────────────────────────────────┐
│  Cursor Composer                        │
├─────────────────────────────────────────┤
│  > Implement OAuth login                │
│                                         │
│  🔒 ULPI: auth/login.ts reserved by     │
│     Alice. Coordinate before editing?   │
│                                         │
│  [Proceed] [Message Alice] [Cancel]     │
└─────────────────────────────────────────┘

Multi-file edits: Cursor can edit multiple files at once. Pre-edit hook checks ALL files:

⚠️  Multi-File Edit Check

Files to edit: 5
├─ src/auth/login.ts (available ✓)
├─ src/auth/logout.ts (available ✓)
├─ src/auth/middleware.ts (RESERVED by Alice ⛔)
├─ tests/auth.test.ts (available ✓)
└─ docs/auth.md (available ✓)

1 file conflict detected. Coordinate with Alice?

[Edit Available Files] [Message Alice] [Cancel All]

Performance

Cursor has excellent hook performance:

Hook	Latency	Notes
session-start	~145ms	Fast startup
pre-edit	~110ms	Batch checks for multi-file
pre-compact	~190ms	Efficient compaction
Overall	~120ms avg	Very good

Troubleshooting

Status bar not showing hooks

Solution: Enable status bar icon in config:

{ "cursor": { "statusBarIcon": true } }

Then reload window.

Composer ignoring file reservations

Solution: Ensure composer integration enabled:

{ "cursor": { "composerIntegration": true } }

Windsurf Setup

Installation

Prerequisites:

Windsurf installed (version ≥ 1.0.0)
ULPI API token
Coordination subscription active

Setup Steps:

Install ULPI Package

npm install -g ulpi

Run Guided Setup

ulpi setup

Select “Windsurf” when prompted.

Restart Windsurf

Close and relaunch Windsurf.

Verify Hooks Active

Check Windsurf’s MCP panel:

MCP Servers:
├─ ULPI Coordination ✓
├─ ULPI Memory ✓
└─ ULPI Hooks (8/8 active) ✓

Configuration

Windsurf hooks are configured in ~/.windsurf/mcp-servers.json:

{
  "mcpServers": {
    "ulpi-hooks": {
      "command": "ulpi-mcp",
      "args": ["hooks"],
      "env": {
        "ULPI_API_TOKEN": "ulpi_sk_...",
        "ULPI_API_URL": "https://api.ulpi.io"
      }
    }
  }
}

Windsurf-Specific Features

👥 Collaboration Session

Participants:
- You (Windsurf-Alice) 🟢
- Bob (Windsurf-Bob) 🟢
- Charlie (Windsurf-Charlie) 🟢

File Reservations:
- auth.ts: Alice (exclusive)
- api.ts: Bob (shared)
- tests.ts: Charlie (shared)

All participants see live reservation updates.

Performance

Windsurf has excellent hook performance:

Hook	Latency	Notes
session-start	~140ms	MCP-native integration
pre-edit	~105ms	Very fast
pre-compact	~185ms	Efficient
Overall	~118ms avg	Excellent

Cline (VS Code Extension) Setup

Installation

Prerequisites:

VS Code installed
Cline extension installed from marketplace
ULPI API token

Setup Steps:

Install Cline Extension

In VS Code:

Press Cmd+Shift+X (Extensions)
Search “Cline”
Click “Install”

Install ULPI Package

npm install -g ulpi

Run Setup for Cline

ulpi setup

Select “Cline (VS Code)” when prompted.

Reload VS Code

Press Cmd+Shift+P → “Developer: Reload Window”

Verify Hooks

Open Cline panel. You should see:

ULPI Hooks: 6/8 active ⚠️
(Missing: pre-compact, subagent-stop)

Limitations

Cline supports 6 out of 8 hooks: ✅ Supported:

session-start
pre-tool-use:edit
post-tool-use:edit
user-prompt-submit
stop
session-end

❌ Not Supported:

pre-compact (Cline doesn’t expose compaction events)
subagent-stop (Cline doesn’t support subagents)

Workaround for pre-compact: Manually create memory snapshots:

# Create snapshot before long break
ulpi memory snapshot --create

Switching Between Assistants

Hooks work across assistants. You can use different assistants for different tasks: Example:

Morning: Use Claude Code for architecture planning
- session-start loads memories
- pre-compact saves decisions
Afternoon: Switch to Cursor for implementation
- session-start loads same memories
- pre-edit reserves files
Evening: Review with Windsurf in collaboration mode
- All file reservations visible to collaborators

All assistants share:

Same ULPI Memory
Same Coordination state
Same file reservations
Same agent messages

Best Practices

Use best assistant for each task

Recommendation:

Architecture/Planning: Claude Code (best context preservation)
Feature Implementation: Cursor (excellent composer mode)
Team Collaboration: Windsurf (real-time collaboration)
Quick Edits: Cline (lightweight, VS Code integrated)

Maintain consistent agent identity

Recommendation: Use same agent name across assistantsConfig:

{
  "agentName": "YourName",  // Same for all assistants
  "agentPrefix": "auto"      // Auto-detects assistant type
}

Result:

Claude-Code-YourName (when using Claude Code)
Cursor-YourName (when using Cursor)
Windsurf-YourName (when using Windsurf)

Benefit: Team knows it’s you regardless of assistant

Sync config across assistants

Recommendation: Use global config for consistencySetup:

# Use global config (applies to all assistants)
ulpi config set --global minImportance=0.5
ulpi config set --global autoReserve=true

Override per assistant if needed:

# Cursor-specific setting
ulpi config set --assistant cursor composerIntegration=true

Troubleshooting

General Issues

Hooks not working after setup

Diagnosis:

# Check hook status
ulpi hooks status

# Check configuration
ulpi config list

# Verify API token
ulpi auth verify

Solutions:

Ensure assistant is restarted after setup
Check API token is valid
Verify Coordination subscription active
Try re-running setup: ulpi setup --force

Some hooks work, others don't

Diagnosis:

# List hook execution history
ulpi hooks history --last 10

Solutions:

Check which hooks are failing
Enable debug mode: ulpi config set debug=true
Check assistant version (may need update)
Review assistant-specific limitations

Hook latency too high

Diagnosis:

# Check hook performance
ulpi hooks performance

Solutions:

Check network latency to ULPI API
Enable caching: ulpi config set cacheEnabled=true
Reduce session-start memory loading: min Importance=0.7
Disable non-critical hooks
