Validate Plugin

Name: validate-plugin
Author: jeremylongshore

Full plugin directory validator combining structural checks and content grading.

Overview

Runs the complete validation pipeline against any plugin directory:

validate-all-plugins.sh for structural validation (plugin.json, file refs, permissions)
validate-skills-schema.py for content validation with 100-point grading

Prerequisites

Python 3 with pyyaml installed
jq available 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>

If the plugin has commands or agents, validate those too:
```
python3 scripts/validate-skills-schema.py --verbose
```
Report the combined results with per-skill 100-point grades

Output

Present results in this format:

Structural Validation:

plugin.json: PASS/FAIL (list any invalid fields)
File references: PASS/FAIL
Script permissions: PASS/FAIL

Content Validation (per SKILL.md):

Grade: A-F (score/100)
Errors: list
Warnings: list

Summary:

Total errors / warnings
Overall verdict: PASS or FAIL

Error Handling

If plugin directory doesn't exist, report and exit
If plugin.json is missing, report as structural failure
If Python or jq not available, report as environment issue
Continue validating remaining files even if one fails

Examples

Example 1: Validate a specific plugin

/validate-plugin plugins/skill-enhancers/skill-creator/

Example 2: Validate current directory

validate this plugin
