Code Reviewer

Q: 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.

Q: How do I install Code Reviewer in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/claude-world/director-mode-lite/tree/main/skills/code-reviewer. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Q: 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.

Q: 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.

Q: Is the Code Reviewer AI skill free?

Yes. It is published on GitHub by claude-world under the MIT license. You only pay your own AI provider for the tokens you use.

Q: 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.

Q: 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.

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 claude-world 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.

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.

Open the app and go to Plugins → Skills.
Choose "Install from GitHub".
Paste the skill folder URL below and confirm.
https://github.com/claude-world/director-mode-lite/tree/main/skills/code-reviewer
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.

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/claude-world/director-mode-lite.git /tmp/director-mode-lite
mkdir -p .claude/skills
cp -r /tmp/director-mode-lite/skills/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.

Review Checklist

Canonical checklist for reviewing code changes. Work through every section.

1. Code Quality

Clear, descriptive naming for functions and variables
Proper function/method length (< 30 lines), focused and single-purpose
Single responsibility principle
No code duplication (DRY)
Code is simple, readable, and self-documenting
Comments explain "why", not "what"

2. Security (OWASP Top 10)

Input validation at system boundaries
SQL injection prevention (parameterized queries)
XSS prevention
Command injection prevention
No exposed secrets, API keys, or credentials
Authentication/Authorization checks
Sensitive data handled securely (no data exposure)

3. Error Handling

Appropriate error handling for edge cases
Meaningful error messages
Graceful degradation where appropriate
No silent failures

4. Performance

No N+1 queries; efficient database queries
Efficient algorithms
Proper caching where beneficial
Memory leak prevention
No unnecessary loops or computations

5. Testing

Tests exist for new code
Happy path and edge cases covered
Test names clearly describe what is being tested

6. Documentation

Complex logic is commented
Public APIs are documented
README updated if needed

Review Process


Step 1: Read the code changes
Step 2: Run through the checklist
Step 3: Provide feedback with:
        - Category (Quality/Security/Error Handling/Performance/Testing/Docs)
        - Severity (Critical/Major/Minor/Suggestion)
        - Specific line reference
        - Suggested fix

Output Format

  - Suggested fix: Use parameterized queries

### Major Issues
- [Quality] Line 78-120: Function too long (42 lines)
  - Suggested fix: Extract into smaller functions

### Minor Issues
- [Docs] Line 10: Missing JSDoc for public function

### Suggestions
- Consider adding input validation at line 23

### Approved
- [ ] Ready to merge (no critical/major issues)
