Dependency Checker

Validate dependencies declared in extends-plugin.json files against installed and enabled plugins.

Usage

• /utils:dependency-checker - Check all enabled plugins
• /utils:dependency-checker --installed - Check all installed plugins
• /utils:dependency-checker --all - Check all plugins in all marketplaces
• /utils:dependency-checker --plugin <name> - Check specific plugin

Workflow

Step 1: Determine Flags

Parse the user's request to determine appropriate flags:

• Default (no args): Check enabled plugins only
• "check installed": Use --installed
• "check all": Use --all
• "check <plugin-name>": Use --plugin <name>

Step 2: Generate CPR Resolver

First, generate the Claude Plugin Root resolver:

# Invoke the find-claude-plugin-root skill to create /tmp/cpr.py
Skill(skill="utils:find-claude-plugin-root")

Step 3: Execute Scripts

# Get plugin root
PLUGIN_ROOT=$(python3 /tmp/cpr.py utils)

# Run dependency checker
python3 "$PLUGIN_ROOT/scripts/dependency-checker.py" [FLAGS] > /tmp/dependency-check.json

# Render tables
python3 "$PLUGIN_ROOT/scripts/table-renderer.py" /tmp/dependency-check.json

# Show resolution steps
python3 "$PLUGIN_ROOT/scripts/resolution-steps.py" /tmp/dependency-check.json

Step 4: Interpret Results

After displaying tables and resolution steps, provide a summary including:

• Total dependencies checked
• Satisfied vs unsatisfied count
• Priority order for fixes (required before optional)
• Additional context from the JSON data

Error Handling

If scripts fail:

1. Verify Python 3 is available
2. Confirm plugin paths exist
3. Check extends-plugin.json for valid JSON syntax
