Module oauth 

OAuth 2.0 authentication support for LLM providers

This module provides OAuth authentication support for various LLM providers, starting with Anthropic Claude Pro/Max subscriptions.

Architecture

• config: OAuth configuration types
• error: Error types for OAuth operations
• flow: OAuth 2.0 authorization code flow implementation
• pkce: PKCE (Proof Key for Code Exchange) implementation
• provider: OAuth provider trait and types
• providers: Concrete provider implementations
• registry: Provider registry for managing providers

Example

use stakpak_shared::oauth::{OAuthFlow, ProviderRegistry};

// Get the Anthropic provider
let registry = ProviderRegistry::new();
let provider = registry.get("anthropic").unwrap();

// Get OAuth config for Claude Pro/Max
let config = provider.oauth_config("claude-max").unwrap();

// Start the OAuth flow
let mut flow = OAuthFlow::new(config);
let auth_url = flow.generate_auth_url();

// User visits auth_url, gets code, then:
// let tokens = flow.exchange_code(code).await?;
// let auth = provider.post_authorize("claude-max", &tokens).await?;
