Configuration

Enhance works with zero config. But you can customize it per-project with a config file.

Config file

Create a .enhancerc.json file in your project root:

.enhancerc.json

{
  "provider": "claude",
  "model": "claude-sonnet-4-6",
  "maxContextTokens": 3000,
  "customInstructions": "Always use React Query for data fetching. Prefer named exports."
}

Also supported: .enhancerc, .enhancerc.yaml, enhance.config.js, or a "enhance" key in package.json.

Options

Key	Type	Default	Description
provider	string	claude	AI provider: claude \| codex \| opencode
model	string	claude-sonnet-4-6	Model ID to use
maxContextTokens	number	3000	Max characters of project files to include as context
customInstructions	string	—	Extra instructions injected into every enhanced prompt

API key

Set via environment variable. Never hardcode in the config file.

Terminal

# Add to ~/.zshrc or ~/.bashrc to make permanent
export ANTHROPIC_API_KEY=sk-ant-...

# Reload shell
source ~/.zshrc

Security note

Never commit API keys to git. The config file is for provider/model preferences only. Keys always come from environment variables.
