schematic-design

EVERY KiCad operation has a corresponding MCP tool. Do NOT claim a tool does not exist without first listing all available tools. Key tools that MUST be used instead of file writes:

• add_symbol — create custom symbol definitions in .kicad_sym files
• create_symbol_library — create new .kicad_sym library files
• create_schematic — create new .kicad_sch files
• create_project — create new .kicad_pro project files If you find yourself thinking "there's no MCP tool for this," you are wrong. Check the tool list again.

KiCad Schematic Design — Plan Executor

This skill executes schematic plans mechanically. All intelligence (component selection, coordinate calculation, wiring decisions) happened in prior phases. This skill reads a plan and executes it.

Response Format

When this skill activates, announce the mode:

• Plan mode: Print exactly: "Using schematic-design to execute the placement plan."
• Modification mode: Print exactly: "Using schematic-design to modify the existing schematic."

Then proceed directly to the pre-flight checks for the appropriate mode. Do not ask the user what to do — the plan or user instructions are the input. Report progress as each placement/wiring step completes, but keep updates brief (one line per step).

Two Modes

Plan Mode (new designs)

Reads specs/schematic-plan.md and executes mechanically. The plan file is the sole source of truth — ignore prior conversation context about how the plan was created. Read the plan, execute the plan.

Pre-flight checks:

1. Verify specs/schematic-plan.md exists and its reviewer returned APPROVED
2. Read page size from plan, call set_page_size immediately if not A4
3. Verify project/schematic files exist (create if needed)
4. If plan references custom symbol library, verify it exists via list_lib_symbols
