Plugin Optimization

Execute plugin validation and optimization workflow. Target: $ARGUMENTS

Background Knowledge

Load plugin-optimizer:plugin-best-practices skill using the Skill tool for component templates, tool invocation rules, and type classification.

Phase 1: Discovery & Validation

Goal: Validate structure and detect issues. Orchestrator MUST NOT apply fixes.

Actions:

Resolve path with realpath and verify existence
Validate .claude-plugin/plugin.json exists
Find component directories: commands/, agents/, skills/, hooks/
Validate components against ${CLAUDE_PLUGIN_ROOT}/examples/ templates
Assess architecture: if commands/ exists with .md files, use AskUserQuestion tool to ask about migrating to skills structure
Run validation: python3 ${CLAUDE_PLUGIN_ROOT}/scripts/validate-plugin.py "$TARGET"
- Options: --check=structure,manifest,frontmatter,tools,tokens
- JSON output: --json
- Verbose: -v, --verbose
Compile issues by severity (Critical, Warning, Info)

Phase 2: Agent-Based Optimization

Goal: Launch agent to apply ALL fixes. Orchestrator does NOT make fixes directly.

Condition: Always execute.

Actions:

Launch plugin-optimizer:plugin-optimizer agent with the following prompt content:
- Target plugin path (absolute path from Phase 1)
- Validation console output (issues list from Phase 1)
- Template validation results
- User decisions (migration choice if applicable)
- INSTRUCTION: Analyze the validation output to identify issues
Agent autonomously applies fixes (MUST use AskUserQuestion tool before applying template fixes, presenting violations with specific examples and before/after comparison)
Agent increments version in .claude-plugin/plugin.json after fixes:
- Patch (x.y.Z+1): Bug fixes
