Claude Code changes

New Documents

Authentication [Source]

New comprehensive guide covering authentication methods for Claude Code. Documents three primary authentication approaches: Claude for Teams/Enterprise (recommended for organizations), Claude Console authentication (for API-based billing), and cloud provider authentication (Bedrock, Vertex AI, Microsoft Foundry). Includes detailed setup steps for each method, credential management details (macOS Keychain storage, supported auth types, custom credential scripts via apiKeyHelper), and refresh interval configuration via CLAUDE_CODE_API_KEY_HELPER_TTL_MS.

Permissions [Source]

New detailed documentation for Claude Code's permission system. Covers the tiered permission system (read-only, Bash commands, file modifications), permission modes (default, acceptEdits, plan, dontAsk, bypassPermissions), and comprehensive permission rule syntax including wildcard patterns. Documents tool-specific rules for Bash, Read/Edit (using gitignore patterns), WebFetch (domain-based), MCP tools, and Task subagents. Includes guidance on working directories, how permissions interact with sandboxing, managed settings for enterprise deployments, settings precedence, and example configurations.
