+description: Run development verification checks (lint, build, and optionally e2e tests)
+argument-hint: "[e2e]"
+---
+
+## Development Test Suite
+
+Run comprehensive development verification checks for the Codu project.
+
+## Current Context
+
+Branch: !`git branch --show-current`
+Status: !`git status --short | head -10`
+
+## Task
+
+Run the following verification steps in order:
+
+### 1. Lint Check
+Run ESLint and verify there are **0 errors** (warnings are acceptable):
+```bash
+npm run lint
+```
+Report the error/warning counts.
+
+### 2. TypeScript Compilation
+Verify TypeScript compiles without errors:
+```bash
+npx tsc --noEmit
+```
+
+### 3. Build Check
+Verify the Next.js build completes successfully:
+```bash
+npm run build
+```
+
+### 4. E2E Tests (if requested)
+If `$ARGUMENTS` includes "e2e", also run E2E tests:
+```bash
+npm run test:e2e
+```
+
+## Output
+
+Provide a clear summary:
+- Lint: PASS/FAIL (X errors, Y warnings)
+- TypeScript: PASS/FAIL
+- Build: PASS/FAIL
+- E2E Tests: PASS/FAIL/SKIPPED
+
+If any check fails, provide details and suggest fixes.
