codewise

LLM-agnostic code review, security scanning, test generation, and documentation — as CLI, MCP server, GitHub Action, or git hook.

Works with any LLM provider: OpenAI, Anthropic, Google Gemini, Ollama, Azure OpenAI, AWS Bedrock — powered by litellm.

🎬 Demo

codewise reviewing code, scanning for vulnerabilities, and generating tests — all from the CLI

Configuration

Create .codewise.yaml in your repo root:

model: gpt-4o-mini
temperature: 0.1
min_severity: low
fail_on: high
output_format: terminal

rules:
  enable_packs:
    - python-best-practices
    - security-basics

  custom:
    - id: no-debug-flags
      pattern: "DEBUG\\s*=\\s*True"
      file_pattern: "*.py"
      severity: high
      message: "Remove debug flags before merging."

    - id: require-error-handling
      llm_check: "Ensure all HTTP calls have try/except."
      file_pattern: "*.py"
      severity: high

    - id: no-fixme-on-main
      pattern: "FIXME|HACK"
      file_pattern: "*.py"
      severity: medium
      branches: [main, master]

hooks:
  pre_commit:
    enabled: true
    fail_on: high
  pre_push:
    enabled: true
    fail_on: high
    max_files: 20
    timeout: 120

Rule Types

Standard Rule Packs

Git Hooks

# Install pre-commit + pre-push hooks
codewise hooks install

# Check status
codewise hooks status

# Remove hooks
codewise hooks uninstall

The pre-push hook reviews all commits being pushed vs the remote branch. It blocks the push if findings exceed the configured severity threshold. Users can always bypass with git push --no-verify.

Configure hook behavior in .codewise.yaml:

hooks:
  pre_push:
    enabled: true
    review: true
    security: true
    fail_on: high
    max_files: 20     # Skip if too many files (avoid slow pushes)
    timeout: 120      # Max seconds

LLM Providers

codewise uses litellm — any model it supports works:

# OpenAI (default)
export CODEWISE_API_KEY=sk-...
codewise review

# Anthropic
codewise review --model claude-sonnet-4-20250514
export ANTHROPIC_API_KEY=sk-ant-...

# Google Gemini
codewise review --model gemini/gemini-2.0-flash
export GEMINI_API_KEY=...

# Ollama (local, free)
codewise review --model ollama/llama3.1

# Azure OpenAI
codewise review --model azure/gpt-4o-mini
export AZURE_API_KEY=...
export AZURE_API_BASE=https://your-deployment.openai.azure.com

# AWS Bedrock
codewise review --model bedrock/anthropic.claude-sonnet-4-20250514-v2:0

MCP Server

Use codewise from any MCP-compatible editor:

# stdio transport (for VS Code / Cursor)
codewise mcp

# SSE transport (for web clients)
codewise mcp --transport sse --port 3000

MCP Tools

VS Code MCP Config

{
  "mcpServers": {
    "codewise": {
      "command": "codewise",
      "args": ["mcp"]
    }
  }
}
