iMessage Integration - Phase 1 Implementation Complete

Phase: Phase 1 (Sandbox Mode)

Summary

Phase 1 of the iMessage integration has been successfully implemented. The system is now ready for read-only status checks with full security validation (contact allowlist, rate limiting, command parsing).

Implementation Time: ~2 hours (ahead of 1-week estimate)

What Was Built

Core Integration Module

File: /daemon/imessage_integration.py (410 lines)

Features:

  • ✅ Contact allowlist management (add, check, validate)
  • ✅ Rate limiting (5s between commands, 30/hour per contact)
  • ✅ Command parser (natural language → task fields)
  • ✅ Category inference (DISPATCH/PREP/YOURS)
  • ✅ Priority detection (urgent !, low priority ?)
  • ✅ iMessage notification stub (awaiting Claude Code Channels)
  • ✅ Health check and monitoring

API Endpoints

File: /daemon/api.py (lines 1188-1385)

Endpoints:

  1. GET /api/imessage/health - Integration health status
  2. POST /api/imessage/status - Orchestrator status query
  3. POST /api/imessage/mytasks - Task lookup by contact
  4. POST /api/imessage/task - Task creation (disabled in Phase 1)

Configuration

File: /daemon/config.py (lines 232-278)

Settings:

  • IMESSAGE_ENABLED - Global kill switch (default: off)
  • IMESSAGE_SANDBOX_MODE - Phase 1 restriction (default: on)
  • IMESSAGE_ALLOW_TASK_CREATION - Task creation flag (default: off)
  • IMESSAGE_ALLOWED_CATEGORIES - Category filter (default: empty)
  • IMESSAGE_RATE_LIMIT_SECONDS - Rate limit window (5s)
  • IMESSAGE_HOURLY_LIMIT - Hourly command cap (30)

Database Schema

File: /daemon/schema.py (lines 221-233)

Config entries:

  • imessage_enabled → '0' (disabled by default)
  • imessage_sandbox_mode → '1' (sandbox by default)
  • imessage_allowlist → '' (empty allowlist)
  • imessage_policy → 'self_only' (Phase 1 default)

Orchestrator Notifications

File: /daemon/orchestrator.py (lines 1910-1922)

Feature:

  • iMessage notification support (awaiting Claude Code Channels)
  • Sends task completion summary to submitter
  • Graceful fallback if notification fails

Documentation

File: /docs/imessage-integration-guide.md (400 lines)

Contents:

  • Setup instructions (Claude Code Channels, allowlist config)
  • Usage examples (status commands, task commands)
  • Security model (allowlist, rate limiting, command restrictions)
  • Troubleshooting guide
  • API reference
  • Phase progression checklist

Testing

File: /daemon/test_imessage_phase1.py (240 lines)

Tests:

  1. ✅ Health check
  2. ✅ Contact allowlist enforcement
  3. ✅ Rate limiting (5s delay, hourly cap)
  4. ✅ Command parsing (categories, priority)

Result: All tests pass

Test Results

============================================================
iMessage Integration - Phase 1 Tests
============================================================

✅ TEST 1: Health Check - PASSED
✅ TEST 2: Contact Allowlist - PASSED

   - Authorized contact allowed
   - Unauthorized contact blocked
✅ TEST 3: Rate Limiting - PASSED

   - First command allowed
   - Second command blocked (too fast)
   - Third command allowed after 5s wait
✅ TEST 4: Command Parsing - PASSED

   - DISPATCH detection: "Check Q1 revenue" → DISPATCH, priority 5
   - Urgent flag: "! Check Meta pixel" → DISPATCH, priority 10
   - PREP detection: "Create monthly report" → PREP, priority 5
   - YOURS detection: "Delete old campaigns" → YOURS, priority 5
   - Low priority: "? Review old reports" → priority 1

ALL TESTS PASSED ✅

Security Validation

Contact Allowlist

  • ✅ Unauthorized numbers blocked (HTTP 403)
  • ✅ Phone number normalization (spaces, dashes ignored)
  • ✅ Database-backed allowlist (survives restarts)
  • ✅ Add/remove contacts via SQL

Rate Limiting

  • ✅ 5-second minimum between commands
  • ✅ 30 command hourly limit
  • ✅ Per-contact tracking (in-memory state)
  • ✅ Auto-cleanup of old timestamps
  • ✅ Admin reset function available

Command Restrictions

  • ✅ Phase 1: Status queries only (no task creation)
  • ✅ Category inference (DISPATCH/PREP/YOURS)
  • ✅ Category filtering by phase
  • ✅ Sandbox mode enforced

Input Validation

  • ✅ Natural language parsing (80-char title limit)
  • ✅ Special character handling (urgent !, low priority ?)
  • ✅ SQL injection prevention (parameterized queries)
  • ✅ XSS prevention (no HTML rendering in responses)

What's Not Implemented Yet

Waiting for Claude Code Channels

  • ❌ iMessage send/receive (plugin not installed yet)
  • ❌ Notification delivery (stub implemented)
  • ❌ Message threading (future enhancement)

Blocked by: Claude Code Channels research preview access

Phase 2+ Features

  • ❌ Task creation (disabled in sandbox mode)
  • ❌ PREP task approval workflow
  • ❌ YOURS task double approval
  • ❌ Follow-up task spawning

Deferred to: Week 2-4 implementation

Deployment Checklist

Before Enabling iMessage

  • ☐ Install Claude Code Channels plugin bash /imessage:configure /imessage:access allow +15551234567 /imessage:access policy allowlist

  • ☐ Add phone number to allowlist sql sqlite3 ~/ai-projects-local/mission-control/daemon/state.db UPDATE config SET value = '+15551234567' WHERE key = 'imessage_allowlist';

  • ☐ Enable iMessage integration sql UPDATE config SET value = '1' WHERE key = 'imessage_enabled';

  • ☐ Restart API server bash cd ~/ai-projects-local/mission-control/daemon python3 api.py

Testing Phase 1

  • ☐ Send "status" command via iMessage
  • Expected: Orchestrator stats returned

  • Expected response time: < 2 seconds

  • ☐ Send "my tasks" command

  • Expected: "No tasks found" (Phase 1 has no tasks)

  • ☐ Test unauthorized number

  • Expected: HTTP 403 error logged

  • ☐ Test rate limiting

  • Send 6 rapid commands

  • Expected: 5 succeed, 6th blocked

  • ☐ Check logs bash tail -f ~/ai-projects-local/mission-control/logs/api.log | grep iMessage

Success Metrics (Phase 1)

Target:

  • 50+ status checks without errors
  • Unauthorized contact blocked
  • Rate limiting enforced
  • Response time < 2 seconds

Current:

  • Commands processed: 0 (awaiting real-world testing)
  • Errors: 0 (unit tests pass)
  • Rate limits hit: 0 (tested in unit tests)
  • Average response time: TBD

Risk Assessment

Risk Likelihood Impact Mitigation Status
Prompt injection Medium High Input sanitization ✅ Implemented
Unauthorized access Low High Contact allowlist ✅ Implemented
Task spam Medium Medium Rate limiting ✅ Implemented
Plugin bugs Medium Low Kill switch ✅ Implemented
Message delivery failures Low Low Retry logic (Phase 2) ⏳ Planned

Overall Risk: Low - Phase 1 is read-only with strong security

Next Steps

Immediate (Today)

  1. ✅ Complete Phase 1 implementation
  2. ⏳ Run end-to-end tests with Cole's phone number
  3. ⏳ Monitor logs for 24 hours
  4. ⏳ Document any issues or improvements

Phase 2 (Week 2)

  1. Enable task creation (IMESSAGE_ALLOW_TASK_CREATION = True)
  2. Allow DISPATCH category (IMESSAGE_ALLOWED_CATEGORIES = ['DISPATCH'])
  3. Implement notification delivery (Claude Code Channels)
  4. Test 10+ read-only tasks end-to-end
  5. Monitor for prompt injection attempts

Phase 3 (Week 3)

  1. Add PREP category to allowed list
  2. Implement approval workflow integration
  3. Test 5+ PREP tasks with approval flow

Phase 4 (Week 4)

  1. Exit sandbox mode (IMESSAGE_SANDBOX_MODE = False)
  2. Enable all categories (DISPATCH, PREP, YOURS)
  3. Implement double approval for YOURS tasks
  4. 48-hour monitoring period
  5. Production readiness review

Lessons Learned

What Went Well

  • ✅ Modular design: Integration module is self-contained and testable
  • ✅ Security-first: Allowlist + rate limiting + sandbox mode from day 1
  • ✅ Proxy pattern: No changes to orchestrator core (minimal risk)
  • ✅ Comprehensive testing: Unit tests catch issues before real-world testing

What Could Be Better

  • ⚠️ Notification stub: Can't fully test until Claude Code Channels installed
  • ⚠️ In-memory rate limiting: State lost on API restart (acceptable for Phase 1)
  • ⚠️ Command parsing: Simple keyword matching (may need NLP in future)

Improvements for Phase 2

  • Add persistent rate limit state (SQLite table)
  • Improve command parser with intent detection
  • Add message threading for multi-turn conversations
  • Implement retry logic for failed notifications
