Get Candid running with your Python project.

Initialize Standards

/candid-init --template python

This generates a Technical.md with Python-specific rules.

Recommended Rules for Python

Add these to your Technical.md:

## Python Code
 
- Functions under 50 lines (split if larger)
- Type hints on all public function signatures
- No mutable default arguments (use None and check)
- Context managers for file and connection handling
 
## Error Handling
 
- Specific exceptions caught (never bare except)
- Custom exceptions inherit from appropriate base class
- Error messages include context for debugging
- Failed operations logged before re-raising
 
## Security
 
- User input sanitized before use
- SQL queries use parameterized statements
- No secrets in code (use environment variables)
- File paths validated against traversal attacks
 
## Testing
 
- New features require pytest tests
- Test files named test_*.py or *_test.py
- Fixtures used for common test setup
- Mocks used for external dependencies

Focus Modes for Python

Security audit

/candid-review --focus security

Check for SQL injection, secret exposure, and input validation issues.

Before code review

/candid-review --focus edge-case

Find unhandled exceptions, missing error states, and boundary conditions.

Run Your First Review

Make some changes and run:

/candid-review

Candid will analyze your Python code against your Technical.md standards.
