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• Outdated packages: !npm outdated 2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/dev/null || pip list --outdated 2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 Dependency Analysis - Audit current versions, identify outdated packages, assess security vulnerabilities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.
