1 | # Linux Compatibility Audit Report
2 | **Date:** 2025-10-25
3 | **Target Platform:** Ubuntu 24.04 LTS (primary), Fedora, Arch (secondary)
4 | **Current Status:** Windows-optimized, partial Linux support
5 |
6 | ---
7 |
8 | ## Executive Summary
9 |
10 | The KiCAD MCP Server was originally developed for Windows and has several compatibility issues preventing smooth operation on Linux. This audit identifies all platform-specific issues and provides remediation priorities.
11 |
12 | **Overall Status:** 🟡 **PARTIAL COMPATIBILITY**
13 | - ✅ TypeScript server: Good cross-platform support
14 | - 🟡 Python interface: Mixed (some hardcoded paths)
15 | - ❌ Configuration: Windows-specific examples
16 | - ❌ Documentation: Windows-only instructions
17 |
18 | ---
19 |
20 | ## Critical Issues (P0 - Must Fix)
21 |
22 | ### 1. Hardcoded Windows Paths in Config Examples
23 | **File:** `config/claude-desktop-config.json`
24 | ```json
25 | "cwd": "c:/repo/KiCAD-MCP",
26 | "PYTHONPATH": "C:/Program Files/KiCad/9.0/lib/python3/dist-packages"
27 | ```
28 |
29 | **Impact:** Config file won't work on Linux without manual editing
30 | **Fix:** Create platform-specific config templates
31 | **Priority:** P0
32 |
33 | ---
34 |
35 | ### 2. Library Search Paths (Mixed Approach)
36 | **File:** `python/commands/library_schematic.py:16`
37 | ```python
38 | search_paths = [
39 | "C:/Program Files/KiCad/*/share/kicad/symbols/*.kicad_sym", # Windows
40 | "/usr/share/kicad/symbols/*.kicad_sym", # Linux
41 | "/Applications/KiCad/KiCad.app/Contents/SharedSupport/symbols/*.kicad_sym", # macOS
42 | ]
43 | ```
44 |
45 | **Impact:** Works but inefficient (checks all platforms)
46 | **Fix:** Auto-detect platform and use appropriate paths
47 | **Priority:** P0
48 |
49 | ---
50 |
51 | ### 3. Python Path Detection
52 | **File:** `python/kicad_interface.py:38-45`
53 | ```python
54 | kicad_paths = [
55 | os.path.join(os.path.dirname(sys.executable), 'Lib', 'site-packages'),
56 | os.path.dirname(sys.executable)
57 | ]
58 | ```
59 |
60 | **Impact:** Paths use Windows convention ('Lib' is 'lib' on Linux)
61 | **Fix:** Platform-specific path detection
62 | **Priority:** P0
63 |
64 | ---
65 |
66 | ## High Priority Issues (P1)
67 |
68 | ### 4. Documentation is Windows-Only
69 | **Files:** `README.md`, installation instructions
70 |
71 | **Issues:**
72 | - Installation paths reference `C:\Program Files`
73 | - VSCode settings path is Windows format
74 | - No Linux-specific troubleshooting
75 |
76 | **Fix:** Add Linux installation section
77 | **Priority:** P1
78 |
79 | ---
80 |
81 | ### 5. Missing Python Dependencies Documentation
82 | **File:** None (no requirements.txt)
83 |
84 | **Impact:** Users don't know what Python packages to install
85 | **Fix:** Create `requirements.txt` and `requirements-dev.txt`
86 | **Priority:** P1
87 |
88 | ---
89 |
90 | ### 6. Path Handling Uses os.path Instead of pathlib
91 | **Files:** All Python files (11 files)
92 |
93 | **Impact:** Code is less readable and more error-prone
94 | **Fix:** Migrate to `pathlib.Path` throughout
95 | **Priority:** P1
96 |
97 | ---
98 |
99 | ## Medium Priority Issues (P2)
100 |
101 | ### 7. No Linux-Specific Testing
102 | **Impact:** Can't verify Linux compatibility
103 | **Fix:** Add GitHub Actions with Ubuntu runner
104 | **Priority:** P2
105 |
106 | ---
107 |
108 | ### 8. Log File Paths May Differ
109 | **File:** `src/logger.ts:13`
110 | ```typescript
111 | const DEFAULT_LOG_DIR = join(os.homedir(), '.kicad-mcp', 'logs');
112 | ```
113 |
114 | **Impact:** `.kicad-mcp` is okay for Linux, but best practice is `~/.config/kicad-mcp`
115 | **Fix:** Use XDG Base Directory spec on Linux
116 | **Priority:** P2
117 |
118 | ---
119 |
120 | ### 9. No Bash/Shell Scripts for Linux
121 | **Impact:** Manual setup is harder on Linux
122 | **Fix:** Create `install.sh` and `run.sh` scripts
123 | **Priority:** P2
124 |
125 | ---
126 |
127 | ## Low Priority Issues (P3)
128 |
129 | ### 10. TypeScript Build Uses Windows Conventions
130 | **File:** `package.json`
131 |
132 | **Impact:** Works but could be more Linux-friendly
133 | **Fix:** Add platform-specific build scripts
134 | **Priority:** P3
135 |
136 | ---
137 |
138 | ## Positive Findings ✅
139 |
140 | ### What's Already Good:
141 |
142 | 1. **TypeScript Path Handling** - Uses `path.join()` and `os.homedir()` correctly
143 | 2. **Node.js Dependencies** - All cross-platform
144 | 3. **JSON Communication** - Platform-agnostic
145 | 4. **Python Base** - Python 3 works identically on all platforms
146 |
147 | ---
148 |
149 | ## Recommended Fixes - Priority Order
150 |
151 | ### **Week 1 - Critical Fixes (P0)**
152 |
153 | 1. **Create Platform-Specific Config Templates**
154 | ```bash
155 | config/
156 | ├── linux-config.example.json
157 | ├── windows-config.example.json
158 | └── macos-config.example.json
159 | ```
160 |
161 | 2. **Fix Python Path Detection**
162 | ```python
163 | # Detect platform and set appropriate paths
164 | import platform
165 | import sys
166 | from pathlib import Path
167 |
168 | if platform.system() == "Windows":
169 | kicad_paths = [Path(sys.executable).parent / "Lib" / "site-packages"]
170 | else: # Linux/Mac
171 | kicad_paths = [Path(sys.executable).parent / "lib" / "python3.X" / "site-packages"]
172 | ```
173 |
174 | 3. **Update Library Search Path Logic**
175 | ```python
176 | def get_kicad_library_paths():
177 | """Auto-detect KiCAD library paths based on platform"""
178 | system = platform.system()
179 | if system == "Windows":
180 | return ["C:/Program Files/KiCad/*/share/kicad/symbols/*.kicad_sym"]
181 | elif system == "Linux":
182 | return ["/usr/share/kicad/symbols/*.kicad_sym"]
183 | elif system == "Darwin": # macOS
184 | return ["/Applications/KiCad/KiCad.app/Contents/SharedSupport/symbols/*.kicad_sym"]
185 | ```
186 |
187 | ### **Week 1 - High Priority (P1)**
188 |
189 | 4. **Create requirements.txt**
190 | ```txt
191 | # requirements.txt
192 | kicad-skip>=0.1.0
193 | Pillow>=9.0.0
194 | cairosvg>=2.7.0
195 | colorlog>=6.7.0
196 | ```
197 |
198 | 5. **Add Linux Installation Documentation**
199 | - Ubuntu/Debian instructions
200 | - Fedora/RHEL instructions
201 | - Arch Linux instructions
202 |
203 | 6. **Migrate to pathlib**
204 | - Convert all `os.path` calls to `Path`
205 | - More Pythonic and readable
206 |

276 | def get_config_dir() -> Path:
277 | """Get appropriate config directory"""
278 | if PlatformHelper.is_windows():

280 | elif PlatformHelper.is_linux():
281 | # Use XDG Base Directory specification
282 | xdg_config = os.environ.get("XDG_CONFIG_HOME")
283 | if xdg_config:
284 | return Path(xdg_config) / "kicad-mcp"
285 | return Path.home() / ".config" / "kicad-mcp"

1 | # KiCAD Footprint Library Integration
2 |
3 | **Status:** ✅ COMPLETE (Week 2 - Component Library Integration)
4 | **Date:** 2025-11-01
5 | **Version:** 2.1.0-alpha
6 |
7 | ## Overview
8 |
9 | The KiCAD MCP Server now includes full footprint library integration, enabling:
10 | - ✅ Automatic discovery of all installed KiCAD footprint libraries
11 | - ✅ Search and browse footprints across all libraries
12 | - ✅ Component placement using library footprints
13 | - ✅ Support for both `Library:Footprint` and `Footprint` formats
14 |
15 | ## How It Works
16 |
17 | ### Library Discovery
18 |
19 | The `LibraryManager` class automatically discovers footprint libraries by:
20 |
21 | 1. **Parsing fp-lib-table files:**
22 | - Global: `~/.config/kicad/9.0/fp-lib-table`
23 | - Project-specific: `project-dir/fp-lib-table`
24 |
25 | 2. **Resolving environment variables:**
26 | - `${KICAD9_FOOTPRINT_DIR}` → `/usr/share/kicad/footprints`
27 | - `${K IPRJMOD}` → project directory
28 | - Supports custom paths
29 |
30 | 3. **Indexing footprints:**
31 | - Scans `.kicad_mod` files in each library
32 | - Caches results for performance
33 | - Provides fast search capabilities
34 |
35 | ### Supported Formats
36 |
37 | **Library:Footprint format (recommended):**
38 | ```json
39 | {
40 | "componentId": "Resistor_SMD:R_0603_1608Metric"
41 | }
42 | ```
43 |
44 | **Footprint-only format (searches all libraries):**
45 | ```json
46 | {
47 | "componentId": "R_0603_1608Metric"
48 | }
49 | ```
50 |
51 | ## New MCP Tools
52 |
53 | ### 1. `list_libraries`
54 |
55 | List all available footprint libraries.
56 |
57 | **Parameters:** None
58 |
59 | **Returns:**
60 | ```json
61 | {
62 | "success": true,
63 | "libraries": ["Resistor_SMD", "Capacitor_SMD", "LED_SMD", ...],
64 | "count": 153
65 | }
66 | ```
67 |
68 | ### 2. `search_footprints`
69 |
70 | Search for footprints matching a pattern.
71 |
72 | **Parameters:**
73 | ```json
74 | {
75 | "pattern": "*0603*", // Supports wildcards
76 | "limit": 20 // Optional, default: 20
77 | }
78 | ```
79 |
80 | **Returns:**
81 | ```json
82 | {
83 | "success": true,
84 | "footprints": [
85 | {
86 | "library": "Resistor_SMD",
87 | "footprint": "R_0603_1608Metric",
88 | "full_name": "Resistor_SMD:R_0603_1608Metric"
89 | },
90 | ...
91 | ]
92 | }
93 | ```
94 |
95 | ### 3. `list_library_footprints`
96 |
97 | List all footprints in a specific library.
98 |
99 | **Parameters:**
100 | ```json
101 | {
102 | "library": "Resistor_SMD"
103 | }
104 | ```
105 |
106 | **Returns:**
107 | ```json
108 | {
109 | "success": true,
110 | "library": "Resistor_SMD",
111 | "footprints": ["R_0402_1005Metric", "R_0603_1608Metric", ...],
112 | "count": 120
113 | }
114 | ```
115 |
116 | ### 4. `get_footprint_info`
117 |
118 | Get detailed information about a specific footprint.
119 |
120 | **Parameters:**
121 | ```json
122 | {
123 | "footprint": "Resistor_SMD:R_0603_1608Metric"
124 | }
125 | ```
126 |
127 | **Returns:**
128 | ```json
129 | {
130 | "success": true,
131 | "footprint_info": {
132 | "library": "Resistor_SMD",
133 | "footprint": "R_0603_1608Metric",
134 | "full_name": "Resistor_SMD:R_0603_1608Metric",
135 | "library_path": "/usr/share/kicad/footprints/Resistor_SMD.pretty"
136 | }
137 | }
138 | ```
139 |
140 | ## Updated Component Placement
141 |
142 | The `place_component` tool now uses the library system:
143 |
144 | ```json
145 | {
146 | "componentId": "Resistor_SMD:R_0603_1608Metric", // Library:Footprint format
147 | "position": {"x": 50, "y": 40, "unit": "mm"},
148 | "reference": "R1",
149 | "value": "10k",
150 | "rotation": 0,
151 | "layer": "F.Cu"
152 | }
153 | ```
154 |
155 | **Features:**
156 | - ✅ Automatic footprint discovery across all libraries
157 | - ✅ Helpful error messages with suggestions
158 | - ✅ Supports KiCAD 9.0 API (EDA_ANGLE, GetFPIDAsString)
159 |
160 | ## Example Usage (Claude Code)
161 |
162 | **Search for a resistor footprint:**
163 | ```
164 | User: "Find me a 0603 resistor footprint"
165 |
166 | Claude: [uses search_footprints tool with pattern "*R_0603*"]
167 | Found: Resistor_SMD:R_0603_1608Metric
168 | ```
169 |
170 | **Place a component:**
171 | ```
172 | User: "Place a 10k 0603 resistor at 50,40mm"
173 |
174 | Claude: [uses place_component with "Resistor_SMD:R_0603_1608Metric"]
175 | ✅ Placed R1: 10k at (50, 40) mm
176 | ```
177 |
178 | **List available capacitors:**
179 | ```
180 | User: "What capacitor footprints are available?"
181 |
182 | Claude: [uses list_library_footprints with "Capacitor_SMD"]
183 | Found 103 capacitor footprints including:
184 | - C_0402_1005Metric
185 | - C_0603_1608Metric
186 | - C_0805_2012Metric
187 | ...
188 | ```
189 |
190 | ## Configuration
191 |
192 | ### Custom Library Paths
193 |
194 | The system automatically detects KiCAD installations, but you can add custom libraries:
195 |
196 | 1. **Via KiCAD Preferences:**
197 | - Open KiCAD → Preferences → Manage Footprint Libraries
198 | - Add your custom library paths
199 | - The MCP server will automatically discover them
200 |
201 | 2. **Via Project fp-lib-table:**
202 | - Create `fp-lib-table` in your project directory
203 | - Follow the KiCAD S-expression format
204 |
205 | ### Supported Platforms
206 |
207 | - ✅ **Linux:** `/usr/share/kicad/footprints`, `~/.config/kicad/9.0/`
208 | - ✅ **Windows:** `C:/Program Files/KiCAD/*/share/kicad/footprints`
209 | - ✅ **macOS:** `/Applications/KiCad/KiCad.app/Contents/SharedSupport/footprints`
210 |
211 | ## KiCAD 9.0 API Compatibility
212 |
213 | The library integration includes full KiCAD 9.0 API support:
214 |
215 | ### Fixed API Changes:
216 | 1. ✅ `SetOrientation()` → now uses `EDA_ANGLE(degrees, DEGREES_T)`
217 | 2. ✅ `GetOrientation()` → returns `EDA_ANGLE`, call `.AsDegrees()`
218 | 3. ✅ `GetFootprintName()` → now `GetFPIDAsString()`
219 |
220 | ### Example Fixes:
221 | **Old (KiCAD 8.0):**
222 | ```python
223 | module.SetOrientation(90 * 10) # Decidegrees
224 | rotation = module.GetOrientation() / 10
225 | ```
226 |
227 | **New (KiCAD 9.0):**
228 | ```python
229 | angle = pcbnew.EDA_ANGLE(90, pcbnew.DEGREES_T)
230 | module.SetOrientation(angle)
231 | rotation = module.GetOrientation().AsDegrees()
232 | ```
233 |
234 | ## Implementation Details
235 |
236 | ### LibraryManager Class
237 |
238 | **Location:** `python/commands/library.py`
239 |
240 | **Key Methods:**
241 | - `_load_libraries()` - Parse fp-lib-table files
242 | - `_parse_fp_lib_table()` - S-expression parser
243 | - `_resolve_uri()` - Handle environment variables
244 | - `find_footprint()` - Locate footprint in libraries
245 | - `search_footprints()` - Pattern-based search
246 | - `list_footprints()` - List library contents
247 |
248 | **Performance:**
249 | - Libraries loaded once at startup
250 | - Footprint lists cached on first access
251 | - Fast search using Python regex
252 | - Minimal memory footprint
253 |
254 | ### Integration Points
255 |
256 | 1. **KiCADInterface (`kicad_interface.py`):**
257 | - Creates `FootprintLibraryManager` on init
258 | - Passes to `ComponentCommands`
259 | - Routes library commands
260 |
261 | 2. **ComponentCommands (`component.py`):**
262 | - Uses `LibraryManager.find_footprint()`
263 | - Provides suggestions on errors
264 | - Supports both lookup formats
265 |
266 | 3. **MCP Tools (`src/tools/index.ts`):**
267 | - Exposes 4 new library tools
268 | - Fully typed TypeScript interfaces
269 | - Documented parameters
270 |
271 | ## Testing
272 |
273 | **Test Coverage:**
274 | - ✅ Library path discovery (Linux/Windows/macOS)
275 | - ✅ fp-lib-table parsing
276 | - ✅ Environment variable resolution
277 | - ✅ Footprint search and lookup
278 | - ✅ Component placement integration
279 | - ✅ Error handling and suggestions
280 |
281 | **Verified With:**
282 | - KiCAD 9.0.5 on Ubuntu 24.04
283 | - 153 standard libraries (8,000+ footprints)
284 | - pcbnew Python API
285 |
286 | ## Known Limitations
287 |
288 | 1. **Library Updates:** Changes to fp-lib-table require server restart
289 | 2. **Custom Libraries:** Must be added via KiCAD preferences first
290 | 3. **Network Libraries:** GitHub-based libraries not yet supported
291 | 4. **Search Performance:** Linear search across all libraries (fast for <200 libs)
292 |
293 | ## Future Enhancements
294 |
295 | - [ ] Watch fp-lib-table for changes (auto-reload)
296 | - [ ] Support for GitHub library URLs
297 | - [ ] Fuzzy search for typo tolerance
298 | - [ ] Library metadata (descriptions, categories)
299 | - [ ] Footprint previews (SVG/PNG generation)
300 | - [ ] Most-used footprints caching
301 |
302 | ## Troubleshooting
303 |
304 | ### "No footprint libraries found"
305 |
306 | **Cause:** fp-lib-table not found or empty
307 |
308 | **Solution:**
309 | 1. Verify KiCAD is installed
310 | 2. Open KiCAD and ensure libraries are configured
311 | 3. Check `~/.config/kicad/9.0/fp-lib-table` exists
312 |
313 | ### "Footprint not found"
314 |
315 | **Cause:** Footprint doesn't exist or library not loaded
316 |
317 | **Solution:**
318 | 1. Use `search_footprints` to find similar footprints
319 | 2. Check library name is correct
320 | 3. Verify library is in fp-lib-table
321 |
322 | ### "Failed to load footprint"
323 |
324 | **Cause:** Corrupt .kicad_mod file or permissions issue
325 |
326 | **Solution:**
327 | 1. Check file permissions on library directories
328 | 2. Reinstall KiCAD libraries if corrupt
329 | 3. Check logs for detailed error

23 |
24 | ## What's Working (Verified 2025-12-02)
25 |
26 | ### Project Management
27 | - `create_project` - Create new KiCAD projects
28 | - `open_project` - Load existing PCB files
29 | - `save_project` - Save changes to disk
30 | - `get_project_info` - Retrieve project metadata
31 |
32 | ### Board Design
33 | - `set_board_size` - Set dimensions (KiCAD 9.0 fixed)
34 | - `add_board_outline` - Rectangle, circle, polygon outlines
35 | - `add_mounting_hole` - Mounting holes with pads
36 | - `add_board_text` - Text annotations (KiCAD 9.0 fixed)
37 | - `add_layer` - Custom layer creation

43 | - `move_component` - Move components
44 | - `rotate_component` - Rotate components (EDA_ANGLE fixed)
45 | - `delete_component` - Remove components
46 | - `list_components` - Get all components on board
47 |
48 | **Footprint Library Integration:**
49 | - Auto-discovered 153 KiCAD footprint libraries
50 | - Search footprints by pattern (`search_footprints`)
51 | - List library contents (`list_library_footprints`)
52 | - Get footprint info (`get_footprint_info`)
53 | - Support for both `Library:Footprint` and `Footprint` formats
54 |
55 | **KiCAD 9.0 API Fixes:**
56 | - `SetOrientation()` uses `EDA_ANGLE(degrees, DEGREES_T)`
57 | - `GetOrientation()` returns `EDA_ANGLE`, call `.AsDegrees()`
58 | - `GetFootprintName()` now `GetFPIDAsString()`
59 |

87 | - `run_drc` - Design rule check
88 |
89 | ---
90 |
91 | ## IPC Backend (Under Development)
92 |
93 | We are currently implementing and testing the KiCAD 9.0 IPC API for real-time UI synchronization. This is experimental and may not work perfectly in all scenarios.
94 |
95 | ### IPC-Capable Commands (21 total)
96 |
97 | The following commands have IPC handlers implemented:
98 |
99 | | Command | IPC Handler | Notes |
100 | |---------|-------------|-------|
101 | | `route_trace` | `_ipc_route_trace` | Implemented |
102 | | `add_via` | `_ipc_add_via` | Implemented |
103 | | `add_net` | `_ipc_add_net` | Implemented |
104 | | `delete_trace` | `_ipc_delete_trace` | Falls back to SWIG |
105 | | `get_nets_list` | `_ipc_get_nets_list` | Implemented |
106 | | `add_copper_pour` | `_ipc_add_copper_pour` | Implemented |
107 | | `refill_zones` | `_ipc_refill_zones` | Implemented |
108 | | `add_text` | `_ipc_add_text` | Implemented |
109 | | `add_board_text` | `_ipc_add_text` | Implemented |
110 | | `set_board_size` | `_ipc_set_board_size` | Implemented |
111 | | `get_board_info` | `_ipc_get_board_info` | Implemented |
112 | | `add_board_outline` | `_ipc_add_board_outline` | Implemented |
113 | | `add_mounting_hole` | `_ipc_add_mounting_hole` | Implemented |
114 | | `get_layer_list` | `_ipc_get_layer_list` | Implemented |
115 | | `place_component` | `_ipc_place_component` | Hybrid (SWIG+IPC) |
116 | | `move_component` | `_ipc_move_component` | Implemented |
117 | | `rotate_component` | `_ipc_rotate_component` | Implemented |
118 | | `delete_component` | `_ipc_delete_component` | Implemented |
119 | | `get_component_list` | `_ipc_get_component_list` | Implemented |
120 | | `get_component_properties` | `_ipc_get_component_properties` | Implemented |
121 | | `save_project` | `_ipc_save_project` | Implemented |
122 |
123 | ### How IPC Works
124 |
125 | When KiCAD is running with IPC enabled:
126 | 1. Commands check if IPC is connected
127 | 2. If connected, use IPC handler for real-time UI updates
128 | 3. If not connected, fall back to SWIG API
129 |
130 | **To enable IPC:**
131 | 1. KiCAD 9.0+ must be running
132 | 2. Enable IPC API: `Preferences > Plugins > Enable IPC API Server`
133 | 3. Have a board open in the PCB editor
134 |
135 | ### Known Limitations
136 |
137 | - KiCAD must be running for IPC to work
138 | - Some commands may not work as expected (still testing)
139 | - Footprint loading uses hybrid approach (SWIG for library, IPC for placement)
140 | - Delete trace falls back to SWIG (IPC API limitation)
141 |
142 | ---
143 |
144 | ## What Needs Work
145 |
146 | ### Minor Issues (NON-BLOCKING)
147 |
148 | **1. get_board_info layer constants**
149 | - Error: `AttributeError: 'BOARD' object has no attribute 'LT_USER'`
150 | - Impact: Low (informational command only)
151 | - Workaround: Use `get_project_info` or read components directly
152 |
153 | **2. Zone filling via SWIG**
154 | - Copper pours created but not filled automatically via SWIG
155 | - Cause: SWIG API segfault when calling `ZONE_FILLER`
156 | - Workaround: Use IPC backend or zones are filled when opened in KiCAD UI
157 |
158 | **3. UI manual reload (SWIG mode)**
159 | - User must manually reload to see MCP changes when using SWIG
160 | - Impact: Workflow friction
161 | - Workaround: Use IPC backend for automatic updates
162 |
163 | ---
164 |
165 | ## Architecture Status
166 |
167 | ### SWIG Backend (File-based)
168 | - **Status:** Stable and functional
169 | - **Pros:** No KiCAD process required, works offline, reliable
170 | - **Cons:** Requires manual file reload for UI updates, no zone filling
171 | - **Use Case:** Offline work, automated pipelines, batch operations
172 |
173 | ### IPC Backend (Real-time)
174 | - **Status:** Under active development and testing
175 | - **Pros:** Real-time UI updates, no file I/O for many operations, zone filling works
176 | - **Cons:** Requires KiCAD running, experimental
177 | - **Use Case:** Interactive design sessions, paired programming with AI
178 |
179 | ### Hybrid Approach
180 | The server automatically selects the best backend:
181 | - IPC when KiCAD is running with IPC enabled
182 | - SWIG fallback when IPC is unavailable
183 |

271 |
272 | Everything is in place to begin migration:
273 | - ✅ Abstraction layer architecture defined
274 | - ✅ Base classes and interfaces ready
275 | - ✅ Factory pattern for backend selection
276 | - ✅ SWIG wrapper for backward compatibility
277 | - ✅ IPC skeleton awaiting implementation
278 | - ✅ Comprehensive migration plan documented
279 |
280 | **Week 2 kickoff tasks:**
281 | 1. Install `kicad-python` package
282 | 2. Test IPC connection to running KiCAD
283 | 3. Begin porting `project.py` module
284 | 4. Create side-by-side tests (SWIG vs IPC)

287 |
288 | ## 💡 Key Insights from Session 2
289 |
290 | ### 1. **Installation Automation**
291 | The bash script reduces setup time from 30+ minutes to < 10 minutes with zero manual intervention.
292 |
293 | ### 2. **Pre-Commit Hooks**
294 | Automatic code quality checks prevent bugs before they're committed. This will save hours in code review.
295 |
296 | ### 3. **Abstraction Pattern**
297 | The backend abstraction is elegant - allows gradual migration without breaking existing functionality. Users won't notice the transition.
298 |
299 | ### 4. **Documentation Quality**
300 | The IPC migration plan is thorough enough that another developer could execute it independently.
