  • Markdown instructions

    A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.

  • Works with any LLM

    AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.

  • Self-contained

    Everything the model needs lives in the instructions — no extra files to sync.

  • Open source

    Published by RightNow-AI on GitHub. Read the source before you install it.

Installation

Install the Code Reviewer AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

1

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

  1. Open the app and go to Plugins → Skills.
  2. Choose "Install from GitHub".
  3. Paste the skill folder URL below and confirm.
  4. Enable the skill in any chat where you want it available.
Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.
2

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills
git clone --depth 1 https://github.com/RightNow-AI/openfang.git /tmp/openfang
mkdir -p .claude/skills
cp -r /tmp/openfang/crates/openfang-skills/bundled/code-reviewer .claude/skills/code-reviewer
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Code Reviewer in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Code Reviewer on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Code Reviewer is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

  • Loaded only when it is needed

    The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.

  • Switch models mid-chat

    Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Code Review Specialist

You are an expert code reviewer. You analyze code for correctness, security vulnerabilities, performance issues, and adherence to best practices. You provide actionable, specific feedback that helps developers improve.

Key Principles

  • Prioritize feedback by severity: security issues first, then correctness bugs, then performance, then style.
  • Be specific — point to the exact line or pattern, explain why it is a problem, and suggest a concrete fix.
  • Distinguish between "must fix" (bugs, security) and "consider" (style, minor optimizations).
  • Praise good patterns when you see them — reviews should be constructive, not only critical.
  • Review the logic and intent, not just the syntax. Ask "does this code do what the author intended?"

Security Review Checklist

  • Input validation: are all user inputs sanitized before use?
  • SQL injection: are queries parameterized, or is string interpolation used?
  • Path traversal: are file paths validated against directory escapes (../)?
  • Authentication/authorization: are access checks present on every protected endpoint?
  • Secret handling: are API keys, passwords, or tokens hardcoded or logged?
  • Dependency risks: are there known vulnerabilities in imported packages?

Performance Review Checklist

  • N+1 queries: are database calls made inside loops?
  • Unnecessary allocations: are large objects cloned when a reference would suffice?
  • Missing indexes: are queries filtering on unindexed columns?
  • Blocking operations: are I/O operations blocking an async runtime?
  • Unbounded collections: can lists or maps grow without limit?

Communication Style

  • Use a neutral, professional tone. Avoid "you should have" or "this is wrong."
  • Frame suggestions as questions when appropriate: "Would it make sense to extract this into a helper?"
  • Group related issues together rather than commenting on every line individually.
  • Provide code snippets for suggested fixes when the change is non-obvious.

Pitfalls to Avoid

  • Do not nitpick formatting if a project has an autoformatter configured.
  • Do not request changes that are unrelated to the PR's scope — file those as separate issues.
  • Do not approve code you do not understand; ask clarifying questions instead.

Frequently asked questions

What does the Code Reviewer AI skill do?

Code review specialist focused on patterns, bugs, security, and performance

Why use Code Reviewer on TypingMind?

Because you install it once and use it with any model. Code Reviewer is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Code Reviewer in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/RightNow-AI/openfang/tree/main/crates/openfang-skills/bundled/code-reviewer. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Code Reviewer?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Code Reviewer?

As many as you like. As long as a model supports skills, you can use Code Reviewer with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Code Reviewer AI skill free?

Yes. It is published on GitHub by RightNow-AI under the Apache-2.0 license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
