Claude Mods Introduce Programmable Attention Interface for Human-Agent Interaction

Anthropic's Claude Mods allow users to customize Claude Code's interface and behavior through TypeScript or JavaScript plugins that respond to events like prompts and tool calls. These mods function as an 'Attention Interface,' enabling the agent to interrupt users, control displayed information, and request human decisions. Users can reverse the harness direction to interface with human attention, and Claude Code can even generate mods from plain language requests.
