## Cross-Project Patterns
### Networking & Connectivity

- **Reusability**: **HIGH** (directly reusable)
- **Transfer to**:
- ✅ All ESP32 PlatformIO projects
- ✅ ESP8266 PlatformIO projects (similar process)
- ⚠️ Other embedded platforms (different tools, same concepts)
- **Key Learnings**: Permission issues, port conflicts, upload protocol selection
#### `esp32-flatbuffers-schema-sync-workflow`
- **Applies to**: Any FlatBuffers project
- **Reusability**: **HIGH** (language/framework agnostic)
- **Transfer to**:
- ✅ All FlatBuffers projects (C++, Python, TypeScript, etc.)
- ✅ Protocol buffer projects (similar concepts)
- ✅ Code generation workflows (general pattern)
- **Key Learnings**: Schema-to-code sync, regeneration triggers, validation
### Infrastructure & Data Management
#### `mcp-server-file-storage-index-sync`
- **Applies to**: Any file-based storage with index
- **Reusability**: **HIGH** (universal pattern)
- **Transfer to**:
- ✅ All MCP servers with file storage
- ✅ Database index synchronization
- ✅ Search index maintenance (Elasticsearch, etc.)
- ✅ Package manager metadata (npm, pip, etc.)
- **Key Learnings**: Index corruption detection, regeneration strategies, prevention
### Memory & Performance
#### `embedded-audio-fft-memory-constraints`
- **Applies to**: ESP32 audio processing
- **Reusability**: **LOW** (specific to ESP32 + audio)
- **Transfer to**:
- ⚠️ Raspberry Pi audio (different memory constraints, similar concepts)
- ⚠️ Other embedded audio (different platforms, same principles)
- ✅ General embedded memory optimization (principles apply)
- **Key Learnings**: Pre-allocation, float32 usage, heap monitoring, fragmentation prevention
## Reuse Opportunities by Project
### ESP32 Projects
**High Reuse** (5 prompts):

- ✅ `esp32-platformio-serial-upload-debugging`
- ✅ `esp32-flatbuffers-schema-sync-workflow`
- ✅ `esp32-mcp-server-http-api-integration`
- ✅ `embedded-audio-fft-memory-constraints`
### MCP Server Projects
**High Reuse** (1 prompt):
- ✅ `mcp-server-file-storage-index-sync`
### Raspberry Pi Projects (mia)
**Medium Reuse** (3 prompts):
- ⚠️ `esp32-mcp-server-http-api-integration` (adapt HTTP library)
- ⚠️ `mcp-server-file-storage-index-sync` (direct reuse)
- ⚠️ `embedded-audio-fft-memory-constraints` (adapt memory constraints)
### General Embedded Projects
**Medium Reuse** (2 prompts):
- ⚠️ `esp32-platformio-serial-upload-debugging` (adapt toolchain)
- ⚠️ `esp32-flatbuffers-schema-sync-workflow` (direct reuse)
### Web/Backend Projects
**Medium Reuse** (1 prompt):
- ⚠️ `esp32-mcp-server-http-api-integration` (adapt framework)
- ⚠️ `mcp-server-file-storage-index-sync` (direct reuse)
## Confidence Levels
| Prompt | Confidence | Success Count | Ready for Reuse |
|--------|-----------|---------------|-----------------|
| `esp32-network-ap-mode-configuration` | low | 1 | ⚠️ Needs validation |
| `esp32-platformio-serial-upload-debugging` | medium | 1 | ✅ Ready |
| `esp32-flatbuffers-schema-sync-workflow` | high | 1 | ✅ Ready |
| `esp32-mcp-server-http-api-integration` | low | 1 | ⚠️ Needs validation |
| `mcp-server-file-storage-index-sync` | medium | 1 | ✅ Ready |
| `embedded-audio-fft-memory-constraints` | medium | 1 | ✅ Ready |
## Next Actions for Cross-Project Transfer
### Week 2: Apply to `mia` Project
1. **Test `mcp-server-file-storage-index-sync`** on mia's infrastructure
- Expected: Direct reuse (same pattern)
- Action: Apply index regeneration script to mia's prompt storage
2. **Adapt `esp32-mcp-server-http-api-integration`** for Raspberry Pi
- Expected: Use FastAPI instead of AsyncWebServer
- Action: Create `raspberry-pi-fastapi-mcp-integration` prompt
3. **Extract Raspberry Pi-specific patterns**
- Expected: GPIO control, systemd service patterns
- Action: Create new prompts from mia project learnings
### Week 3: Generalize High-Reuse Patterns
1. **Create generic `platformio-upload-debugging`** prompt
- Remove ESP32-specific details
- Add platform selection logic
2. **Create generic `file-storage-index-sync`** prompt
- Remove MCP-specific details
- Make framework-agnostic
## Success Metrics
- **Cross-Project Reuse**: 3+ prompts successfully applied to other projects
- **Confidence Improvement**: 2+ prompts upgraded from "low" to "medium/high"
- **New Prompts Created**: 2-3 prompts from cross-project learnings
- **Time Saved**: 30% reduction in setup time for new projects
## Knowledge Gaps Identified
### Missing Patterns
1. **Raspberry Pi Networking** - Need AP mode equivalent for RPi
2. **Docker-based MCP Servers** - Containerization patterns
3. **Multi-Device Deployment** - Deploying to multiple ESP32s simultaneously
4. **CI/CD Integration** - Automated testing and deployment
### Low Confidence Areas
- ESP32 AP mode (needs more validation)
- HTTP API integration (needs production testing)
