StudioClaude Mods: Flipping the Harness Inside Out
Dan McAteer writes in Latent Space about Claude Code's Claude Mods, which use TypeScript/JavaScript functions to hook into events like prompts, tool calls, and UI rendering in CLI and Desktop environments, allowing customization of agent behavior and interface. Anthropic has built-in six mods; the author highlights 'You Should Know' and a custom-built 'Next Steps Supervisor,' comparing them with ChatGPT's Intelligent UI and Cursor's PR Routing & Approval. While the latter two feature vendor-designed attention interfaces, Claude Mods are co-authored by users and Claude. The article also notes risks regarding noise, cost (approximately 5–6k input-equivalent tokens per check), and trust due to unsandboxed mods.
Based on practical experience with self-built mods and an analysis of noise, cost, and trust implications, the author compares the ownership of design rights across three attention interfaces, offering direct reference for customizing agent workflows.
