+# Rust MCP Client Refactor - Handoff Prompt
+
+**For:** Fresh Claude agent
+**Project:** LIFE-PLANNER
+**Date:** 01/08/2026
+
+---
+
+## Context
+
+We successfully built a high-performance iMessage CLI using the **Rust client + Python daemon** pattern, achieving **19x faster performance** than the original MCP-based approach (40ms vs 763ms per operation).
+
+The architecture:
+- **Rust CLI** (`wolfies-imessage`): Fast ~3ms spawn, sends requests via Unix socket
+- **Python daemon** (`imessage_daemon.py`): Warm process handling iMessage operations
+- **Protocol**: JSON-RPC over Unix socket at `~/.wolfies-imessage/daemon.sock`
+
+This is now distributed via Homebrew (`brew install wolfiesch/executive-function/wolfies-imessage`).
+
+---
+
+## Task: Extend Pattern to Other MCP Servers
+
+Three Python MCP servers currently exist that could benefit from Rust CLI wrappers:
+
+| Module | Current Location | MCP Tools |
+|--------|-----------------|-----------|
+| **Gmail** | `src/integrations/gmail/server.py` | list_emails, get_email, search_emails, send_email, get_unread_count |
+| **Calendar** | `src/integrations/google_calendar/server.py` | list_events, get_event, create_event, find_free_time |
+| **Reminders** | `Reminders/mcp_server/server.py` | create_reminder, list_reminders, complete_reminder, delete_reminder, list_reminder_lists |
+
+---
+
+## Reference Implementation
+
+Study these files to understand the pattern:
+
+### Rust Client (shared library + iMessage binary)
+```
+Texting/gateway/wolfies-client/
+├── Cargo.toml                    # Workspace definition
+├── crates/
+│   ├── wolfies-core/             # Shared library
+│   │   ├── src/lib.rs           # Protocol, client, response types
+│   │   └── Cargo.toml
+│   └── wolfies-imessage/         # iMessage-specific binary
+│       ├── src/main.rs          # CLI entry point
+│       └── Cargo.toml
+```
+
+### Python Daemon
+```
+Texting/gateway/
+├── imessage_daemon.py           # Unix socket server, handles JSON-RPC
+├── imessage_daemon_client.py    # Python client for testing
+└── output_utils.py              # Shared output formatting
+```
+
+### Key Files to Read
+1. `Texting/gateway/wolfies-client/crates/wolfies-core/src/lib.rs` - Protocol definition
+2. `Texting/gateway/wolfies-client/crates/wolfies-imessage/src/main.rs` - CLI structure
+3. `Texting/gateway/imessage_daemon.py` - Daemon architecture
+4. `Plans/Rust_Gateway_Framework_2026-01-08.md` - Original implementation plan
+
+---
+
+## Benchmarking Approach
+
+We used a normalized workload benchmark to compare implementations:
+
+### Benchmark Script
+`Texting/benchmarks/normalized_workload_benchmarks.py`
+
+### Workloads Tested
+1. **recent** - Get recent messages (light read)
+2. **unread** - Get unread messages (light read)
+3. **find** - Search messages (medium read)
+4. **send** - Send message (write operation)
+5. **contacts** - List contacts (metadata read)
+
+### Metrics Captured
+- Cold start time (first request)
+- Warm request time (subsequent requests)
+- P50, P95, P99 latencies
+- Memory usage
+- Throughput (requests/second)
+
+### Before/After Comparison
+Create baseline benchmarks BEFORE implementing Rust clients, then compare after.
+
+---
+
+## Proposed Phases
+
+### Phase 1: Gmail Rust Client
+1. Create `wolfies-gmail` crate in workspace
+2. Convert `gmail/server.py` to daemon mode (Unix socket)
+3. Implement Rust CLI with subcommands: `list`, `search`, `read`, `send`, `unread`
+4. Benchmark before/after
+5. Update Homebrew formula
+
+### Phase 2: Calendar Rust Client
+1. Create `wolfies-calendar` crate
+2. Convert `google_calendar/server.py` to daemon mode
+3. Implement Rust CLI: `list`, `get`, `create`, `free-time`
+4. Benchmark before/after
+5. Update Homebrew formula
+
+### Phase 3: Reminders Rust Client
+1. Create `wolfies-reminders` crate
+2. Convert `Reminders/mcp_server/server.py` to daemon mode
+3. Implement Rust CLI: `create`, `list`, `complete`, `delete`, `lists`
+4. Benchmark before/after
+5. Update Homebrew formula
+
+---
+
+## Questions to Consider
+
+1. **Is Rust worth it for these?** iMessage benefited because it's used for quick lookups (`unread`, `recent`). Gmail/Calendar/Reminders are primarily MCP servers for Claude Code - direct CLI use is less common. Benchmark first to see if there's a real bottleneck.
+
+2. **Daemon vs Direct?** iMessage uses a daemon because the database reads are expensive to initialize. Gmail/Calendar use OAuth which has its own warm-up cost. Profile to see where time is spent.
+
+3. **Shared credentials?** Gmail and Calendar could share OAuth tokens. Consider a unified Google daemon.
+
+---
+
+## Quick Start Commands
+
+```bash
+# Read the iMessage implementation
+cat Plans/Rust_Gateway_Framework_2026-01-08.md
+
+# Check the Rust workspace structure
+ls -la Texting/gateway/wolfies-client/crates/
+
+# Read the core library
+cat Texting/gateway/wolfies-client/crates/wolfies-core/src/lib.rs
+
+# Run existing benchmarks
+python3 -m Texting.benchmarks.normalized_workload_benchmarks --help
+
+# Check current MCP servers
+cat src/integrations/gmail/server.py | head -100
+cat src/integrations/google_calendar/server.py | head -100
+cat Reminders/mcp_server/server.py | head -100
+```
+
+---
+
+## Success Criteria
+
+- [ ] Baseline benchmarks for each MCP server
+- [ ] Rust CLI achieving <50ms for common operations
+- [ ] Homebrew formulas updated with Rust binaries
+- [ ] Before/after performance comparison documented
+- [ ] All existing functionality preserved
+
+---
+
+## Notes
+
+- The Homebrew tap is at `wolfiesch/homebrew-executive-function`
+- Release workflow at `.github/workflows/release.yml` handles multi-module builds
+- Current version is v0.2.0
