# extension-dev-skill AI Skill for EasyEDA Pro extension plugin development. Provides scenario-driven recipes, complete API reference, code generation standards, and debugging toolchain. ## Core Principles 1. **Never guess APIs** — Check `resources/references/` first; no matching doc = does not exist 2. **Verify mount path** — Class name ≠ eda property name. Always confirm via the mapping table below 3. **Verify return types** — `get()` and `getAll()` on the same class may return different interface types 4. **SCH modify ≠ PCB modify** — SCH uses class-level `modify()` method; PCB uses `setState_*().done()` chain 5. **Browser APIs forbidden in main process** — No `localStorage`, `window`, `document`; allowed inside iframe only 6. **Document type values** — SCH=1, PCB=3, FOOTPRINT=4 (PCB is NOT 2) 7. **console.log forbidden** — Only `console.warn` and `console.error` are allowed in generated code ## When to Use **Applicable:** - Creating or modifying EasyEDA Pro extension plugins - Querying API method signatures via `resources/` documentation - Configuring `extension.json`, locales i18n files, or build processes - Automating plugin import/debugging via `eext-dev-mcp` MCP tools **Not applicable:** - General TypeScript/JavaScript questions unrelated to EasyEDA Pro - Non-EasyEDA Pro EDA tools - Workspace has no `extension.json` and user did not request initialization --- ## Scenario Quick Reference (Recipes) When user intent matches a scenario below, **read the correspon
