Feature Deep-Dives

Custom Rules (CodeRev Exclusive)

Define team-specific rules in .coderev-rules.yaml:

rules:
  - id: no-print-statements
    pattern: "print\\("
    message: "Use logging module instead of print()"
    severity: warning
    languages: [python]
    
  - id: require-error-handling
    description: "All API calls must have error handling"
    check: |
      async_http_calls_without_try_catch
    severity: error
    
  - id: max-function-length
    check: function_lines > 50
    message: "Functions should be under 50 lines"
    severity: info

No other tool offers this level of customizable rule definition.

Local Development Workflow

CodeRev is the only tool designed for local-first development:

# Review before you commit
coderev review src/new_feature.py

# Review staged changes
coderev diff --staged

# Interactive TUI mode
coderev review . --interactive

# Auto-fix issues
coderev review app.py --fix

Pre-commit Integration

# .pre-commit-config.yaml
repos:
  - repo: https://github.com/limem01/coderev
    rev: v1.0.0
    hooks:
      - id: coderev
        args: [--fail-on, high]

Catch issues before they reach PR review.
