/setup-updates

Generate a minimal /update-app command that updates dependencies and fixes deprecations.

Step 1: Detect Project Type

Check for config files:

• package.json → JavaScript/TypeScript (npm/yarn/pnpm/bun)
• pyproject.toml or requirements.txt → Python (pip/poetry)
• go.mod → Go
• Cargo.toml → Rust
• composer.json → PHP

Step 2: Detect Package Manager

For JavaScript/TypeScript: Check for lock files:

• package-lock.json → npm
• yarn.lock → yarn
• pnpm-lock.yaml → pnpm
• bun.lockb → bun

For Python: Check for:

• poetry.lock → poetry
• Otherwise → pip

Step 3: Generate /update-app Command

Create .claude/commands/update-app.md:

---
name: update-app
description: Update dependencies, fix deprecations and warnings
---

# Dependency Update & Deprecation Fix

## Step 1: Check for Updates

[INSERT CHECK COMMAND]

## Step 2: Update Dependencies

[INSERT UPDATE COMMAND]

## Step 3: Check for Deprecations & Warnings

Run installation and check output:
[INSERT INSTALL COMMAND]

Read ALL output carefully. Look for:
- Deprecation warnings
- Security vulnerabilities
- Peer dependency warnings
- Breaking changes

## Step 4: Fix Issues

For each warning/deprecation:
1. Research the recommended replacement or fix
2. Update code/dependencies accordingly
3. Re-run installation
4. Verify no warnings remain

## Step 5: Run Quality Checks

[INSERT QUALITY CHECK COMMANDS]

Fix all errors before completing.

## Step 6: Verify Clean Install

Ensure a fresh install works:
1. Delete dependency folders/caches
2. Run clean install
3. Verify ZERO warnings/errors
4. Confirm all dependencies resolve correctly

Step 4: Customize by Project Type

Replace placeholders with actual commands:

JavaScript/TypeScript (npm):

## Step 1: Check for Updates
```bash
npm outdated

Step 2: Update Dependencies

npm update
npm audit fix

Step 3: Check for Deprecations & Warnings

rm -rf node_modules package-lock.json
npm install

Step 5: Run Quality Checks

npm run lint
npm run typecheck

Step 6: Verify Clean Install

rm -rf node_modules package-lock.json
npm install

### JavaScript/TypeScript (yarn):
```markdown
## Step 1: Check for Updates
```bash
yarn outdated

Step 2: Update Dependencies

yarn upgrade
yarn audit

Step 3: Check for Deprecations & Warnings

rm -rf node_modules yarn.lock
yarn install

### Python (pip):
```markdown
## Step 1: Check for Updates
```bash
pip list --outdated

Step 2: Update Dependencies

pip install --upgrade -r requirements.txt

Step 3: Check for Deprecations & Warnings

pip install -r requirements.txt

Step 5: Run Quality Checks

mypy .
pylint src/

### Python (poetry):
```markdown
## Step 1: Check for Updates
```bash
poetry show --outdated

Step 2: Update Dependencies

poetry update

Step 3: Check for Deprecations & Warnings

poetry install

### Go:
```markdown
## Step 1: Check for Updates
```bash
go list -u -m all

Step 2: Update Dependencies

go get -u ./...
go mod tidy

Step 3: Check for Deprecations & Warnings

go mod download

Step 5: Run Quality Checks

go vet ./...
gofmt -l .

### Rust:
```markdown
## Step 1: Check for Updates
```bash
cargo outdated

Step 2: Update Dependencies

cargo update

Step 3: Check for Deprecations & Warnings

cargo check

Step 5: Run Quality Checks

cargo clippy
cargo fmt --check

## Step 5: Confirm Completion

Tell the user:
- ✅ `/update-app` created
- 🔄 Updates: [package manager commands]
- ⚠️ Zero-tolerance for deprecations/warnings
- 🛡️ Security audit included
- ✨ Clean install verification enabled
