File contents

When the user asks to refresh or rename the current session's title:

Compose the summary myself, from conversation context. I already have the full conversation in context: pick a 3-7 word title (max 50 chars) that captures the current topic. Do not call any external generator: that would spawn a Haiku inference (slow), and a fresh summary I'd pass to it tends to drift away from what I already know.

Use sentence case. Capitalize the first word and proper nouns only.
Determine the session_id and transcript path.
- session_id is in the env var CLAUDE_SESSION_ID if set, otherwise: take the basename (without .jsonl) of the most recently modified *.jsonl file directly under ~/.claude/projects/<sanitized-cwd>/ where <sanitized-cwd> is the current working directory with / replaced by -.
- The transcript path is ~/.claude/projects/<sanitized-cwd>/<session_id>.jsonl.
Apply via the helper. The helper auto-prepends the timestamp prefix (MM-DD@HH:MM) extracted from the first custom-title line in the transcript, so I should pass only the summary part:
```
/Users/kde/code/dotfiles/dotfiles/.claude/hooks/session-title.py set "$session_id" "$transcript" "Refactor API client error handling"
```
The helper sanitizes (strips control chars, rejects path-shaped values, caps at 80 chars), writes the sidecar at ~/.claude/session-titles/<session_id>, and writes OSC 0 to update the terminal tab immediately. The UserPromptSubmit hook applies the sidecar title at the next prompt through Claude Code's supported rename path (the same write /rename uses), which persists it in the transcript and re-applies it on every later start/resume: the new title lands one prompt after this step.
Confirm in one short sentence, e.g.: Session title updated to: 04-29@10:14 Refactor API client error handling
