Pattern: Claude Code Hook System Reaches Enterprise Maturity — Conditional Logic, OAuth Federation, and Plugin Governance Ship in v2.1.85

Releasebot / Claude Code Docs·medium signal

v2.1.85 delivers three enterprise-grade hook capabilities simultaneously: conditional `if` fields using permission rule syntax for selective hook firing, MCP OAuth following RFC 9728 for federated authorization server discovery, and organization-level plugin installation policies. Combined with PreToolUse hooks now satisfying AskUserQuestion for custom UI integration, this represents the hook system graduating from 'developer convenience' to 'enterprise governance primitive.' The pattern: Claude Code's permission and hook architecture is becoming the control plane for organizational AI agent policy.
