# Pre Push

> Run pre-push checks including tests and linting to ensure code is clean and ready to push. Automatically detects project type and available scripts. Runs independent checks in parallel using agents.

Run pre-push checks to ensure code quality before pushing to remote.

**Usage:**
- `/pre-push` - Run all pre-push checks for the current project

**Instructions:**

1. **Check for npm pre-push script:**
   - Look for `package.json` in the current directory
   - If found, check if it has a `pre-push` script in the `scripts` section
   - If the script exists, run `npm run pre-push` and report the results
   - If successful, inform the user and STOP here

2. **If no pre-push script exists, auto-detect and run checks in parallel:**

   a. **Identify project type:**
      - Check for `package.json` (Node.js/JavaScript/TypeScript project)
      - Check for `pyproject.toml`, `setup.py`, `requirements.txt` (Python project)
      - Check for `Cargo.toml` (Rust project)
      - Check for `go.mod` (Go project)
      - Check for other language-specific files

   b. **Detect available checks** (linting, tests, build) for the project type. Then **run independent checks in parallel** using the `Task` tool (`subagent_type: general-purpose`) with `run_in_background: true`:
      - Spawn one agent per independent check category (e.g., linting agent, test agent, build agent)
      - Checks that don't depend on each other should run concurrently — typically linting and tests are independent, while build may depend on type-checking

   c. **Linting checks:**
      - **Node.js/JavaScript/TypeScript:**
        - Check for ESLint: `eslint` in package.json scripts or `.eslintrc*` file
        - Check for Prettier: `prettier` in package.json scripts or `.prettierrc*` file
        - Check for TypeScript: `tsc` in package.json scripts or `tsconfig.json` file
        - Run: `npm run lint` or `npx eslint .` or `npm run type-check` or `npx tsc --noEmit`

      - **Python:**
        - Check for: `pylint`, `flake8`, `black`, `mypy`, `ruff`
        - Run available linters (e.g., `pylint src/`, `flake8 .`, `black --check .`, `mypy .`)

      - **Rust:**
        - Run: `cargo fmt --check` and `cargo clippy`

      - **Go:**
        - Run: `go fmt ./...` and `golint ./...` or `go vet ./...`

   d. **Test checks:**
      - **Node.js:** Check for test scripts in package.json
        - Run: `npm test` or `npm run test:ci` (if available)

      - **Python:**
        - Check for: `pytest`, `unittest`, `nose2`
        - Run: `pytest` or `python -m pytest` or `python -m unittest discover`

      - **Rust:**
        - Run: `cargo test`

      - **Go:**
        - Run: `go test ./...`

   e. **Build checks:**
      - If applicable, try building the project to ensure no compilation errors
      - **Node.js:** `npm run build` (if script exists)
      - **Rust:** `cargo build`
      - **Go:** `go build ./...`

3. **Report results:**
   - Wait for all parallel agents to complete and aggregate their results
   - Provide a clear summary of all checks performed
   - Report pass/fail status for each check
   - If any checks fail, show the errors and suggest fixes
   - Include the commands that were run for transparency
   - If all checks pass, confirm the code is ready to push

4. **Handle edge cases:**
   - If no tests or linting tools are detected, warn the user and ask if they want to proceed without checks
   - If commands fail due to missing dependencies, suggest installation commands
   - If in a monorepo or workspace, detect and handle appropriately

**Example output format:**

```
## Pre-Push Checks

### Linting
ESLint passed
Prettier check passed
TypeScript compilation passed

### Testing
All tests passed (24 tests, 0 failures)

### Build
Build successful

---

All pre-push checks passed! Code is ready to push.

Commands run:
- npm run lint
- npm test
- npm run build
```

**On failure:**

```
## Pre-Push Checks

### Linting
ESLint failed

Error in src/components/Button.tsx:
  15:7  error  'onClick' is missing in props validation  react/prop-types

### Testing
All tests passed

---

Pre-push checks failed. Please fix the issues above before pushing.
