Claude Code 2.1.283 adds prompt-audit and exact model allowlists
Claude Code 2.1.283 (Sept 25) adds /doctor prompt-audit (alias /checkup prompt-audit) to flag outdated patterns in CLAUDE.md, skills, agents, and commands, plus managed availableModelsMatch: exact and deniedModels so new model versions stay blocked until an admin lists them. Opt-in gateway header x-claude-code-prompt-id groups multi-request prompts; the release also hardens MCP reconnect and plugin validation.
