Avoid duplicating logic across the codebase. Instead, extract common functionality into well-named helper functions or standalone utilities. This improves code readability, simplifies maintenance, and centralizes logic for easier updates.

Examples where this applies:

Before:

if (provider.toLowerCase() === "githubcopilot" && !apiKey) {
  apiKey = await fetchGithubCopilotApiKey();
  // Additional logic for handling the API key...
} else if (cli.flags.login) {
  if (provider.toLowerCase() === "githubcopilot") {
    apiKey = await fetchGithubCopilotApiKey();
    // Duplicate logic...
  }
}

After:

function handleGithubCopilotLogin() {
  // Centralized login logic
}

if (provider.toLowerCase() === "githubcopilot" && !apiKey) {
  apiKey = await handleGithubCopilotLogin();
} else if (cli.flags.login) {
  if (provider.toLowerCase() === "githubcopilot") {
    apiKey = await handleGithubCopilotLogin();
  }
}
