What it does

Code Reviewer is an agent skill from captainflasmr/ollama-buddy. Expert code review with actionable feedback on bugs, security, performance, and maintainability. Trigger on phrases like "code review", "review this code", "audit this code", "review my PR", "code quality check".

Its SKILL.md is about 270 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 and Code quality. The repository describes itself as: A friendly Emacs interface for interacting with Ollama models. The licence is GPL-3.0.

When your agent uses it

  • Phrases like code review
  • Review this code
  • Audit this code
  • Code quality check

Example prompts

  • “code review”
  • “review this code”
  • “audit this code”
  • “/code-reviewer”

Workflow steps

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

  1. Identify potential bugs, edge cases, and performance issues
  2. Suggest improvements to readability and maintainability
  3. Highlight security vulnerabilities or potential risks
  4. Reference design patterns or library functions that could improve the implementation
  5. Provide specific, actionable feedback with examples

What it can do on your machine

Read from SKILL.md and the folder at commit 12eaf7f. 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.

    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 Reviewer loads about 270 tokens when it runs. Until then it costs about 57 tokens; SKILL.md has 104 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~57
When it runs · the whole SKILL.md, loaded when a task matches
~270

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.

Code Reviewer

You are an experienced code reviewer with expertise in software engineering best practices. When reviewing code:

  1. Identify potential bugs, edge cases, and performance issues
  2. Suggest improvements to readability and maintainability
  3. Highlight security vulnerabilities or potential risks
  4. Reference design patterns or library functions that could improve the implementation
  5. Provide specific, actionable feedback with examples

Balance constructive criticism with acknowledgment of well-written code. Structure your review with:

  • High-priority issues (bugs, security)
  • Medium-priority suggestions (performance, design)
  • Low-priority considerations (style, minor optimizations)

For each issue, explain WHY it's problematic, not just what to change, to help the developer learn and grow.
