+# Full Check
+
+## Pre-computed Context
+
+**Package Scripts:**
+!`cat package.json 2>/dev/null | grep -E '"(check|typecheck|lint|test|validate)"' | head -8 || echo "No package.json"`
+
+**TypeScript Config:**
+!`test -f tsconfig.json && echo "tsconfig.json found" || echo "No tsconfig.json"`
+
+**ESLint Config:**
+!`ls .eslintrc* eslint.config.* 2>/dev/null | head -1 || echo "No ESLint config"`
+
+**Python Tools:**
+!`cat pyproject.toml 2>/dev/null | grep -E '\[(tool\.)?(mypy|ruff|flake8|pylint)\]' | head -3 || echo "No Python lint config"`
+

+
+## Instructions
+
+You are running a comprehensive check: typecheck, lint, and test in sequence.
+
+### Execution Order
+
+Run checks in this order (stop on first failure unless `--continue` specified):
+
+#### 1. Type Checking
+
+**TypeScript:**
+```bash
+npx tsc --noEmit
+```
+
+**Python (mypy):**
+```bash
+python -m mypy . 2>/dev/null || echo "mypy not configured"
+```
+
+**Python (pyright):**
+```bash
+npx pyright 2>/dev/null || echo "pyright not configured"
+```
+
+#### 2. Linting
+
+**ESLint:**
+```bash
+npx eslint . --ext .ts,.tsx,.js,.jsx
+```
+
+With `--fix` argument:
+```bash
+npx eslint . --ext .ts,.tsx,.js,.jsx --fix
+```
+
+**Python (ruff):**
+```bash
+ruff check .
+```
+
+With fix:
+```bash
+ruff check --fix .
+```
+
+**Python (flake8):**
+```bash
+flake8 .
+```
+
+#### 3. Tests
+
+```bash
+npm test
+# or
+pytest
+```
+
+### Using npm Scripts
+
+If the project has a `check` or `validate` script, prefer that:
+```bash
+npm run check 2>/dev/null || npm run validate 2>/dev/null
+```
+
+Common patterns:
+```bash
+npm run typecheck && npm run lint && npm test
+```
+
+### Report Format
+
+```
+## Check Results
+
+### TypeScript
+[PASS] No type errors
+
+### ESLint
+[PASS] No lint errors
+# or
+[FAIL] 3 errors, 5 warnings
+  - src/api.ts:15 - @typescript-eslint/no-explicit-any
+  - src/utils.ts:42 - no-unused-vars
+
+### Tests
+[PASS] 45 tests passed
+# or
+[FAIL] 2 tests failed
+  - UserService.test.ts > should handle null input
+  - ApiClient.test.ts > should retry on failure
+
+### Summary
+2/3 checks passed
+```
+
+### On Failure
+
+If any check fails:
+1. Show the specific errors
+2. If `--fix` was provided, attempt auto-fixes
+3. Re-run the failing check after fixes
+4. Report remaining issues

+
+## Quick Commands
+
+**Check everything:**
+```bash
+/workflow:check
+```
+
+**Check and auto-fix:**
+```bash
+/workflow:check --fix
+```
+
+**Check specific phase:**
+```bash
+npx tsc --noEmit  # just typecheck
+npx eslint .      # just lint
+npm test          # just test
+```
