# Update Dependencies

Update and modernize project dependencies with safety checks: **$ARGUMENTS**

## Current Dependencies State

- Package manager: @package.json or @requirements.txt or @Cargo.toml (detect package manager)
- Outdated packages: !`npm outdated 2>/dev/null || pip list --outdated 2>/dev/null || echo "Manual check needed"`
- Security issues: !`npm audit --audit-level=moderate 2>/dev/null || pip check 2>/dev/null || echo "Run security audit"`
- Lock files: @package-lock.json or @poetry.lock or @Cargo.lock

## Task

Systematically update project dependencies with comprehensive testing and compatibility validation:

**Update Strategy**: Use $ARGUMENTS to specify patch updates, minor updates, major updates, or security-only updates

**Update Process**:
1. **Dependency Analysis** - Audit current versions, identify outdated packages, assess security vulnerabilities
2. **Impact Assessment** - Check changelogs, breaking changes, deprecation warnings, compatibility matrix
3. **Staged Updates** - Apply patch updates first, then minor, finally major versions with testing between stages
4. **Testing & Validation** - Run full test suite, build verification, integration testing, performance checks
5. **Rollback Strategy** - Document changes, create restore points, maintain rollback procedures
6. **Documentation Updates** - Update README, dependencies list, migration guides, team notifications

**Safety Features**: Automated testing between updates, dependency conflict resolution, security vulnerability prioritization.

**Output**: Updated dependency manifest with comprehensive testing results, security audit report, and upgrade documentation.
