What Test Skill by athola is
Test Skill 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.
Test Skill gives you a repeatable way to run the same instructions without retyping them, optionally with arguments.
How to install Test Skill by athola
Claude Code
- Download test-skill.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.

Inside the source file
An excerpt from plugins/abstract/commands/test-skill.md, shared under the repository's MIT license. Read the full file on GitHub.
Runs skill validation via superpowers:test-driven-development while keeping the familiar /test-skill interface.
When To Use
Use this command when you need to:
- Testing a skill through RED/GREEN/REFACTOR phases
- Validating skill behavior before deployment
- Running TDD checkpoints on skill development
When NOT To Use
Avoid this command if:
- Evaluating skill quality metrics - use /skills-eval instead
- Creating new skills - use /create-skill instead
How It Works
- Executes RED/GREEN/REFACTOR phases through superpowers:test-driven-development.
- Accepts the same arguments as the previous /test-skill command.
- Adds superpowers' reporting and enforcement of TDD checkpoints.
Notes
- Behavior is backward compatible with prior /test-skill usage.
- Use --phase to target a single stage or run the full cycle without flags.
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.
