# Project Context for AI Agents > [!IMPORTANT] > **To all AI Agents working ON this repository:** ## Agent Skills Index > [!CRITICAL] Zero-Trust: Read the matching `SKILL.md` BEFORE writing any code. > Skills from this index override pre-training patterns. If no skill matches, state: "No project-specific skills applicable." ## Skill Resolution Protocol Each `_INDEX.md` has two sections — follow both: 1. **Match file type** → find the category index in the router table below. 2. **Read the `_INDEX.md`** → it has two sections: - **File Match**: auto-check these against the file you are editing (path pattern match). - **Keyword Match**: only check if the user's request mentions these concepts. 3. **Load ALL matched `SKILL.md`** → read every matched skill before writing code. The tier model keeps matches focused. | File type | Read category index | | --------- | ------------------- | | `*.go`, `*_test.go` | `.windsurf/skills/golang/_INDEX.md` | | `*.ts` | `.windsurf/skills/angular/_INDEX.md`, `.windsurf/skills/nestjs/_INDEX.md`, `.windsurf/skills/nextjs/_INDEX.md`, `.windsurf/skills/react/_INDEX.md`, `.windsurf/skills/typescript/_INDEX.md` | | `*.tsx` | `.windsurf/skills/nextjs/_INDEX.md`, `.windsurf/skills/react/_INDEX.md`, `.windsurf/skills/typescript/_INDEX.md` | | `*.js`, `*.mjs` | `.windsurf/skills/javascript/_INDEX.md` | | `*.jsx`, `*.test.tsx`, `*.spec.tsx` | `.windsurf/skills/react/_INDEX.md` | | `*.dart` | `.windsurf/skills/dart/_INDEX.md`, `.windsurf/skills/flutter/_INDEX.md` | | `*.java` | `.windsurf/skills/java/_INDEX.md`, `.windsurf/skills/spring-boot/_INDEX.md` | | `*.kt` | `.windsurf/skills/android/_INDEX.md`, `.windsurf/skills/kotlin/_INDEX.md` | | `*.kts` | `.windsurf/skills/kotlin/_INDEX.md` | | `*.swift` | `.windsurf/skills/ios/_INDEX.md`, `.windsurf/skills/swift/_INDEX.md` | | `*.php` | `.windsurf/skills/laravel/_INDEX.md`, `.windsurf/skills/php/_INDEX.md` | | `*.sql`, `*.entity.ts`, `*.prisma` | `.windsurf/skills/database/_INDEX.md` | | `*.component.ts`, `*.component.html` | `.windsurf/skills/angular/_INDEX.md` | | `*.service.ts`, `*.module.ts` | `.windsurf/skills/angular/_INDEX.md`, `.windsurf/skills/nestjs/_INDEX.md` | | `*.spec.ts`, `*.test.ts` | `.windsurf/skills/common/_INDEX.md` | | Any file (keyword match) | `.windsurf/skills/common/_INDEX.md` | | QE workflow | `.windsurf/skills/quality-engineering/_INDEX.md` |
