Claude Code Mod Categories

UI mods change what you see in Claude Code. They open panes beside the transcript, place bands above the prompt, restyle tool rows and the spinner, or switch the whole theme. Drawing shows in the terminal and the Desktop app's Code tab, not in the VS Code chat panel.

Prompt mods work on what you send to Claude. They read or rewrite submitted prompts, add sections to the system prompt, or route a prompt to a different model or effort level.

Tool mods step into Claude's tool calls. They can block a risky command, rewrite arguments, trim a noisy result before the model reads it, or register new tools Claude can call.

Command mods add slash commands that run your code at once, even while Claude is working, without spending a Claude turn.

Workflow mods manage how a session runs: compaction and context size, subagents, model routing and spending. Several call models on your plan, so check their access report.
