Summary

Add an init command for guided setup, config test for connectivity verification, and config clear to remove all stored credentials.

Current State

• Has: config show, config set-api-key, config set-account-id, config set-region, config delete-api-key, config delete-account-id, config fix-permissions
• Missing: guided init wizard, config test, config clear (clear all at once)

Commands to Add

1. newrelic-cli init

Interactive setup wizard:

$ newrelic-cli init
New Relic CLI Setup

API Key (NRAK-...): ****
Account ID: 12345
Region (US/EU) [US]: US

Testing connection...
✓ API key valid
✓ Account 12345 accessible

Configuration saved.

Try it out:
  newrelic-cli apps list
  newrelic-cli nrql query "SELECT count(*) FROM Transaction"

Features:

• Interactive prompts for API key, account ID, region
• Connectivity verification (unless --no-verify)
• Existing config detection with overwrite prompt
• Secure storage (Keychain on macOS, config file on Linux)
• Optional: --api-key, --account-id, --region flags for non-interactive use

2. newrelic-cli config test

Explicit connectivity test:

$ newrelic-cli config test
Testing connection to New Relic (US region)...
✓ API key valid
✓ Account 12345 accessible
✓ NerdGraph API responding

Account: My Account (12345)
Region: US

On failure:

$ newrelic-cli config test
Testing connection to New Relic (US region)...
✗ API key invalid or expired

Check your credentials with: newrelic-cli config show
Reconfigure with: newrelic-cli init

3. newrelic-cli config clear

Remove all stored credentials at once:

$ newrelic-cli config clear
Cleared API key from keychain
Cleared account ID
Cleared region setting

Note: Environment variables (NEWRELIC_*) will still be used if set.

This is simpler than running config delete-api-key + config delete-account-id separately.

Implementation Notes

• Can use NerdGraph introspection query or simple account query to verify connectivity
• init should call the same verification logic as config test
• Consider charmbracelet/huh for TUI prompts or simple stdin prompts
