@weavetab/plugin-auth BETA!!!!!!!!!!

Zero-Leak Enterprise Session & Cookie Vault for Weavetab.

Capture, encrypt, and inject authenticated browser sessions directly over the Chrome DevTools Protocol socket without exposing credentials or session tokens to agent prompt context.

The Problem

When AI coding and automation agents encounter OAuth flows, 2FA prompts, or SSO authentication barriers, they break. Passing raw cookies or credentials directly into LLM prompts creates severe security risks, prompt injection vulnerabilities, and token budget exhaustion.

The Architecture

@weavetab/plugin-auth solves authentication via Layer 0 CDP:

1. Snapshot (plugin_auth_capture): Extracts active cookies and origin storage from the developer's real browser session. The bundle is immediately encrypted on disk using AES-256-GCM with a local machine key (~/.weavetab/vault/<service>.enc).
2. Zero-Token Injection (plugin_auth_inject): When the agent operates on that service, it calls plugin_auth_inject({ service: "github" }). The plugin decrypts the bundle locally and writes cookies directly into the browser tab via CDP Network.setCookies.
3. Zero Credentials in Prompt Context: The LLM prompt context receives only execution metadata ({ success: true, service: "github", authenticated: true }). Raw tokens never touch agent conversation context.
