dancing-bear: Skill for Claude Code

Install tmux Session Auto-Namer

Installs the Claude Code hook that automatically renames your tmux session to a short AI-generated summary of what you're working on, updated every 20 prompts.

Step 0: Disclose what the hook captures, and get consent

This hook records prompt text. Do not install it without telling the user first and getting an explicit yes.

What it does on every prompt (configs/llm/tmux-session-namer.py:50-95):

• Appends the first 120 characters of the prompt to $XDG_CACHE_HOME/claude/prompts-<session-id>.txt, falling back to ~/.cache/claude/... when XDG_CACHE_HOME is unset (tmux-session-namer.py:51). Trimmed to the last 200 lines. The directory is created 0700 and the file opened 0600, so it is user-private — but it is still prompt text at rest on disk.

  Resolve the real path before asking, so consent names the actual location. This must match the hook's own fallback exactly (tmux-session-namer.py:70-73): an empty XDG_CACHE_HOME counts as unset per the XDG spec, and a set-but-relative value is rejected too, since joining it would land under the current working directory rather than the user's home:

  python3 -I -S -c "import os; _xdg = os.environ.get('XDG_CACHE_HOME') or ''; _xdg = _xdg if os.path.isabs(_xdg) else os.path.expanduser('~/.cache'); print(os.path.join(_xdg, 'claude'))"
  

• Every 20th prompt, sends the last 20 recorded lines to claude -p to generate the session name. That is an outbound model call containing those prompt fragments.

Prompts from unrelated work can contain credentials, tokens, customer data or other PII, and this capture does not distinguish them. Say this plainly, in these terms, and install only on an explicit yes:

This hook saves the first 120 characters of every prompt to /prompts-*.txt and sends the last 20 of them to claude -p every 20th prompt, to generate the session name. Prompt text can include secrets or personal data. Install it? (y/n)
