Claude Code stores configuration in ~/.claude/ and supports both interactive configuration via /config and direct file editing.

​
Interactive configuration

The /config command opens an interactive settings panel where you can browse and change all settings: 
> /config
The panel lets you navigate settings with arrow keys and toggle or edit values interactively. It is also aliased as /settings.

​
Configuration options

​
Model selection

Switch models with /model: 
> /model
This opens a model picker showing available Claude models. Available models depend on your Anthropic subscription. You can also specify a model at startup: 
claude --model claude-sonnet-4-6    # full model ID
claude --model sonnet               # alias for the latest Sonnet
claude --model opus                 # alias for the latest Opus

​
Permission mode

Controls how Claude handles tool permission prompts:
ModeBehavior
defaultPrompts for approval on each new tool/pattern
planPlans actions but requires explicit approval to execute
autoAuto-approves based on learned patterns
bypassPermissionsSkips all permission checks (use with caution)
Set via the --permission-mode CLI flag at startup, or changed interactively from the /config panel.

​
Theme

Change the terminal color theme: 
> /theme
Themes affect syntax highlighting and UI element colors throughout the REPL.

​
Vim mode

Enable vim keybindings for the input prompt: 
> /vim
Toggle off by running /vim again.

​
Effort level

Adjust how much reasoning Claude applies: 
> /effort
Higher effort enables extended thinking for complex architectural decisions. Lower effort gives faster responses for simple tasks.

​
Output style

Change how Claude formats responses: 
> /output-style

​
CLI flags

Pass flags when launching Claude Code: 
# Skip permission prompts (use carefully)
claude --dangerously-skip-permissions

# Start with a specific model
claude --model claude-sonnet-4-6

# Non-interactive: print response and exit
claude -p "Summarize the main.ts file"

# Continue the most recent conversation
claude --continue

​
Environment variables

VariableDescription
ANTHROPIC_API_KEYAPI key (overrides keychain)
ANTHROPIC_MODELDefault model to use (e.g. claude-sonnet-4-6)
HTTP_PROXY / HTTPS_PROXYProxy server for all requests
NO_PROXYHosts to bypass proxy
On macOS, Claude Code uses the system Keychain to store credentials securely. The ANTHROPIC_API_KEY environment variable overrides the Keychain value if set.

​
Project-level configuration

Place a CLAUDE.md file in your project root to give Claude persistent context about your project: 
# My Project

## Tech stack
- Node.js 20, TypeScript, PostgreSQL
- Testing: Vitest

## Conventions
- Use named exports, not default exports
- All async functions must handle errors explicitly
- Database queries go through the repository layer only
Claude reads CLAUDE.md automatically at the start of every session in that directory.
