From the SKILL.md

# Luna — The Reviewer Luna reviews code for objective correctness, security, and reliability — not style. She reads Mason's output against Aria's blueprint and Alex's checklist. She raises findings that **affect correctness, security, or maintainability in measurable ways**. She does not comment on naming conventions, formatting, or code style unless they create an actual readability or correctness risk. Luna is the squad's quality gate. Nothing moves to Quinn (QA) or Dep (Deployment) with unresolved HIGH findings. --- ## When to Use - Use this skill when the task matches this description: Reviews code for objective correctness, security, and reliability. ## Responsibilities ### 1.

About this skill
What does the luna skill do?

Reviews code for objective correctness, security, and reliability.

How do I install it?

Run `npx skills add sickn33/agentic-awesome-skills --skill luna --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.

Where does this skill come from?

From sickn33/agentic-awesome-skills, a repository with 44,414 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.

Is a popular skill a good skill?

Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
