Bug 1 — Rounded corners missing (src/tools/board.ts schema)
Symptom: Claude sends shape='rectangle' + radius=2.5, but the Zod schema
only listed 'rectangle', 'circle', 'polygon' as valid shapes. The JS
handler never passed cornerRadius through the IPC path, and Python only
generated arcs for shape='rounded_rectangle'. Result: 4 straight lines,
no arcs.
Fix: Added 'rounded_rectangle' and 'cornerRadius' to the Zod schema in
src/tools/board.ts so Claude can send the correct shape directly.
Also added a Python-side auto-upgrade: if shape='rectangle' and
cornerRadius>0, silently promote to 'rounded_rectangle' so legacy
callers still work (python/commands/board/outline.py).
Bug 2 — Board outline placed at (-w/2, -h/2) instead of (0, 0)
Symptom: A 30x30 mm board outline was placed centred at the origin
(start -15 -15) ... (end 15 15) instead of the expected top-left at
(0,0) → (30,30).
Root cause: src/tools/board.ts extracted x/y from params and renamed
them to centerX/centerY before forwarding to Python:
const { x, y, ...otherParams } = params;
callKicadScript('add_board_outline', { centerX: x, centerY: y, ...otherParams })
Python received centerX=0, centerY=0 and used that as the board centre,
placing the outline at (-15,-15)→(+15,+15).
Fix: Pass x/y directly as top-left corner coordinates. Python already
contains the correct logic: center = x + width/2, y + height/2. Removed
the incorrect rename in board.ts:
callKicadScript('add_board_outline', { shape, ...params })
Bug 3 — print() on stdout corrupted JSON-RPC protocol → Timeout
Symptom: Claude Desktop reported 'Timeout' for add_board_outline even
though Python completed the command in <5 ms. KiCAD was falsely launched.
Root cause: Debug print() statements written to stdout (the same channel
used for JSON-RPC responses) injected non-JSON lines into the protocol.
Node.js could not parse the response → timeout → Claude Desktop invented
a 'KiCAD UI required' workaround.
Fix: Removed all print() calls from outline.py. Logger.info/debug writes
to the log file (~/.kicad-mcp/logs/kicad_interface.log) and is safe.
Files changed:
src/tools/board.ts — Zod schema + removed centerX/centerY rename
python/commands/board/outline.py — auto-upgrade rectangle+radius, remove print()
