validate-all-plugins.shfor structural validation (plugin.json, file refs, permissions)validate-skills-schema.pyfor content validation with 100-point grading
Prerequisites
- Python 3 with
pyyamlinstalled jqavailable on PATH- Run from the claude-code-plugins repository root
Instructions
- Identify the target plugin directory (must contain
.claude-plugin/plugin.json) - Run structural validation:
./scripts/validate-all-plugins.sh <plugin-directory>
- Run content validation on any SKILL.md files found:
python3 scripts/validate-skills-schema.py --verbose <path-to-SKILL.md>

python3 scripts/validate-skills-schema.py --verbose
- Report the combined results with per-skill 100-point grades

Structural Validation:
- plugin.json: PASS/FAIL (list any invalid fields)
