What Validate Plugin by athola is

Validate Plugin by athola is a slash command published in the athola/claude-night-market repository on GitHub, which has about 339 stars. The repository describes itself as: “23 Claude Code plugins: TDD enforcement hooks, git/PR workflows, spec-driven development, code review, project lifecycle, fix-from-error, maintenance automation, context optimization, research, and multi-LLM delegation. 186 skills, 128 commands, 54 agents.”

A slash command is a reusable prompt saved as a markdown file and run by typing its name after a slash. In Claude Code, custom commands have been merged into skills: a file in .claude/commands/ and a skill folder in .claude/skills/ both create the same kind of command, and existing command files keep working.

Validate Plugin gives you a repeatable way to run the same instructions without retyping them, optionally with arguments.

How to install Validate Plugin by athola

Claude Code

Download validate-plugin.md from the repository.
Save it to ~/.claude/commands/ (all projects) or .claude/commands/ (one project). As a skill, you can instead save it as ~/.claude/skills/<name>/SKILL.md.
Run it by typing / followed by its name.

Claude Cowork

Turn the command into a skill: create a folder with the file saved as SKILL.md and zip it.
In Customize → Skills, click +, then upload the ZIP.
Run it from any task with / and the skill name.

What It Checks

The validator performs detailed checks:

Critical Requirements

.claude-plugin/plugin.json exists and is valid JSON
Required name field is present
Plugin name follows kebab-case convention
Referenced files and paths exist
Directories are in correct locations (not nested in .claude-plugin/)

Warnings

Path format (should be relative with ./)
Semantic versioning format
Directory structure matches references

Recommendations

Recommended metadata fields (version, description, author, license)
Enhanced Claude configuration options
Skill frontmatter completeness

Examples

Validate Current Plugin

cd ~/claude-night-market/plugins/archetypes
/validate-plugin

Batch Validate Multiple Plugins

for plugin in ~/claude-night-market/plugins/*; do
  /validate-plugin "$plugin"
done

Implementation

Run the Python validation script:

python3 ${CLAUDE_PLUGIN_ROOT}/scripts/validate_plugin.py "${1:-.}"

Before you install

Read the whole file first. Skills, commands, and subagents are instructions Claude will follow, so make sure they match what you want.
Check which tools, scripts, or MCP servers it uses. Local servers and scripts run with your permissions.
Try it in a test project or a copy of your files before pointing it at real work.
Pin the version you tested, and review changes before updating.
Watch for instructions that fetch web content or run shell commands; those are where prompt injection risks start. See our prompt injection guide.
