What it does

Code Review is an agent skill from aide-family/moon. Reviews code for correctness and potential bugs, pinpoints bug locations by file and line, and suggests concrete fixes. Use when the user asks for a code review, wants to find bugs, or mentions reviewing code or changes.

Its SKILL.md is about 820 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Code review, Debugging and Monitoring and alerting. It works with Elasticsearch, Redis, Docker and Kubernetes. The repository describes itself as: Moon is a versatile monitoring and alerting platform designed for multiple domains, supporting various application scenarios such as cloud-native, Internet of Things (IoT), and…

When your agent uses it

  • The user asks for a code review
  • Wants to find bugs
  • Mentions reviewing code

Example prompts

  • “Use the code-review skill to review code for correctness and potential bugs, pinpoints bug locations by file and line, and suggests concrete fixes”
  • “/code-review”

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. Read the code in scope (file(s) or diff the user provided).
  2. Identify potential bugs, including
  3. For each finding: state file path, line number(s), and a short recommended solution.

What it can do on your machine

Read from SKILL.md and the folder at commit 50ece37. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Code Review loads about 815 tokens when it runs. Until then it costs about 58 tokens; SKILL.md has 309 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~58
When it runs · the whole SKILL.md, loaded when a task matches
~815

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 309 words (~815 tokens).

“Review the given code for correctness and potential bugs. For each issue found, report the exact location (file and line) and provide a recommended fix.”
