Dependency Analyzer Skill

Purpose

The Dependency Analyzer skill provides comprehensive dependency analysis capabilities for Python projects. It parses dependency configuration files (requirements.txt, pyproject.toml), builds dependency trees, detects version conflicts, and checks compatibility constraints.

Key Functions:

• Parse and analyze current project dependencies
• Identify new dependencies required for features
• Build visual dependency trees
• Detect version conflicts and incompatibilities
• Check compatibility across Python versions
• Generate structured dependency reports

When to Use

Use this skill when you need to:

• Analyze current project dependencies before adding new features
• Identify all dependencies required for a new feature implementation
• Detect version conflicts between dependencies
• Build dependency trees to understand package relationships
• Verify compatibility of new dependencies with existing ones
• Generate dependency reports for documentation

Typical Scenarios:

• Phase 2 design (dependency analysis for PRP)
• Pre-implementation dependency planning
• Dependency upgrade planning
• Conflict resolution
• Security vulnerability assessment (dependency version analysis)

Workflow

1. Parse Current Dependencies

Action: Read and parse all dependency configuration files in the project

# Check for requirements.txt
if [ -f requirements.txt ]; then
  echo "Found requirements.txt"
  cat requirements.txt
fi

# Check for pyproject.toml
if [ -f pyproject.toml ]; then
  echo "Found pyproject.toml"
  grep -A 30 "dependencies\|requires" pyproject.toml
fi

# Check for setup.py
if [ -f setup.py ]; then
  echo "Found setup.py"
  grep -A 20 "install_requires\|extras_require" setup.py
fi

Output: Inventory of current dependencies with versions

2. Build Dependency Tree

Action: Use dependency-checker script to build complete dependency tree

  --analyze \
  --project-root . \
  --output-format tree
