Cc Tab Titles — AI skill for Claude Code

cc-tab-titles

A Claude Code plugin that automatically sets your terminal tab title to an AI-generated summary of what you're working on.

**Before:** Every tab shows `Claude Code` **After:** Tabs show things like `Fixing sandbox hook exclusions` or `Building React dashboard`

How It Works

• SessionStart hook — claims tab ownership and sets an initial [slug] new session title.
• Stop hook — after each Claude response, generates a short [slug] objective summary using Haiku and sets the tab title via OSC escape sequences. Runs in the background so it doesn't block.
• UserPromptSubmit hook — restores the saved title a moment after you submit a message, preventing Claude Code from resetting the title while it's thinking.

Pinning a Title with `/rename`

Run Claude Code's built-in `/rename ` and automatic Haiku titles stop overriding the tab until you `/rename` to a different value. Use this whenever you want a stable, hand-picked label.

• In cmux, the renamed session is shown natively, so the plugin simply gets out of the way — it clears its own tab override and lets cmux display the name.
• In other terminals, the rename value is applied to the tab title directly.

Installation

/plugin marketplace add STRML/cc-tab-titles
/plugin install cc-tab-titles@STRML

Restart Claude Code after installing.

Requirements

• claude CLI in your PATH (used for Haiku summarization)
