## How It Works

Same mechanism as the Outlook hack:

1. Teams stores an MSAL refresh token in `localStorage`
2. This token is exchanged for a Graph API access token using Teams' first-party client ID
3. The client ID (`5e3ce6c0-2b1f-4285-8d4b-75ee78787346`) has pre-authorized Graph scopes
4. Token auto-rotates on each use — perpetual access as long as it's used within 90 days

## Shared Token Architecture

Both skills read from the same file:

Extract the token once → both `outlook` and `teams` CLIs work. If either skill refreshes the token, the other benefits.

## Sibling Skill: Outlook Hack

This skill shares the same MSAL refresh token with [**outlook-hack**](https://clawhub.com/globalcaos/outlook-hack). **One extraction covers both.** Extract the token once → get full chat access (this skill) AND email access (Outlook Hack).

Both skills read and write to the same credentials file:

(() => {
  const keys = Object.keys(localStorage).filter(
    (k) => k.includes("refreshtoken") || k.includes("RefreshToken"),
  );
  const results = keys.map((k) => {
    const parsed = JSON.parse(localStorage.getItem(k));
    return { key: k, secret: parsed.secret, client_id: parsed.client_id };
  });
  // Also get tenant ID
  const accountKeys = Object.keys(localStorage).filter((k) => {
    try {
      return JSON.parse(localStorage.getItem(k)).tenantId;
    } catch {
      return false;
    }
  });
  let tenantId = null;
  for (const k of accountKeys) {
    try {
      tenantId = JSON.parse(localStorage.getItem(k)).tenantId;
      break;
    } catch {}
  }
  return { tokens: results, tenantId };
})();
