Plugin Toolkit

Tools for working with Claude Code plugins: analyze their structure, add standard polish, and manage features.

Commands

Command	Purpose
/plugin-toolkit:analyze <path>	Produce structured analysis documentation
/plugin-toolkit:polish <path>	Add standard utility commands (help, status, on/off)
/plugin-toolkit:feature <action> <path>	Add, remove, or modify plugin features

---

/plugin-toolkit:analyze

Produce comprehensive analysis of any Claude Code plugin.

Usage

/plugin-toolkit:analyze ~/path/to/plugin
/plugin-toolkit:analyze .  # Current directory

Output

Creates analysis/ directory with:

analysis/
├── ANALYSIS.md           # Architecture, data flow, components
├── RECOMMENDATIONS.md    # Prioritized improvements
├── INTEGRATION_WORKFLOWS.md  # Cross-plugin patterns
└── SKILL_REVIEW.md       # Quality ratings

Process

1. Scan plugin structure using plugin-scanner agent
2. Evaluate quality using quality-checker agent
3. Generate documentation using analysis-template reference

Analysis Criteria

From references/quality-checklist.md:

• Plugin metadata completeness
• Command consistency and coverage
• Hook implementation (opt-out exists?)
• Documentation quality
• Error handling
• Maintenance burden (duplication?)
• Integration potential

/plugin-toolkit:polish

Add standard utility infrastructure to any plugin.

Usage

/plugin-toolkit:polish ~/path/to/plugin
/plugin-toolkit:polish . --skip-changelog  # Skip CHANGELOG creation

What It Adds

Component	Description
/help command	Lists all commands with descriptions
/status command	Shows current plugin state
/off command	Disables auto-activation (if hooks exist)
/on command	Enables auto-activation
CHANGELOG.md	Version history (if missing)
Error handling	Adds to hook scripts

Smart Behavior

• Detects existing hooks and only adds on/off if relevant
• Scans existing commands to generate help content
• Idempotent - won't duplicate if already present
• Preserves existing file formatting

Process

1. Scan plugin using plugin-scanner agent
2. Check existing utilities - skip what's already present
3. Generate commands using command-template reference
4. Add hooks if plugin uses auto-activation
5. Create CHANGELOG if missing

/plugin-toolkit:feature

Add, remove, or modify plugin features.

Usage

/plugin-toolkit:feature add <path> command <name> "<description>"
/plugin-toolkit:feature add <path> hook <event> <script>
/plugin-toolkit:feature add <path> trait <name> "<description>"
/plugin-toolkit:feature add <path> agent <name> "<description>"

/plugin-toolkit:feature remove <path> command <name>
/plugin-toolkit:feature remove <path> hook <event>

/plugin-toolkit:feature change <path> command <name> --description "<new>"

Examples

Add a new command:

/plugin-toolkit:feature add ~/my-plugin command "review" "Review code for issues"

Add a hook:

/plugin-toolkit:feature add ~/my-plugin hook "UserPromptSubmit" "inject-context.sh"

Remove a command:

/plugin-toolkit:feature remove ~/my-plugin command "deprecated-cmd"

Modify a command:

/plugin-toolkit:feature change ~/my-plugin command "help" --description "Updated help text"

What It Handles

Add:

• Creates command/trait/agent markdown file
• Updates plugin.json if needed
• Creates hook script with boilerplate
• Updates SKILL.md references

Remove:

• Removes the file
• Cleans up plugin.json references
• Removes hook entries
• Warns about potential breakage

Change:

• Modifies existing files in place
• Updates related references

Composability

This skill uses shared components:

Agents

• plugin-scanner - Explores plugin structure, returns inventory
• quality-checker - Evaluates against checklist, returns ratings

References

• analysis-template.md - Structure for analysis docs
• command-template.md - Boilerplate for new commands
• quality-checklist.md - Evaluation criteria
• hook-patterns.md - Common hook implementations

Examples

Full Plugin Review Workflow

# 1. Analyze the plugin
/plugin-toolkit:analyze ~/claude/my-plugin

# 2. Review the analysis
cat ~/claude/my-plugin/analysis/RECOMMENDATIONS.md

# 3. Apply standard polish
/plugin-toolkit:polish ~/claude/my-plugin

# 4. Add any custom features
/plugin-toolkit:feature add ~/claude/my-plugin command "custom" "My custom command"

Quick Polish for New Plugin

# Just add utilities, skip analysis
/plugin-toolkit:polish ~/claude/my-plugin

Feature Management

# Add a debugging command
/plugin-toolkit:feature add . command "debug" "Show debugging information"

# Later, remove it
/plugin-toolkit:feature remove . command "debug"
