Generate a concise, sentence-case title (3-7 words) that captures the main topic or goal of this coding session. The title should be clear enough that the user recognizes the session in a list. Use sentence case: capitalize only the first word and proper nouns.

Return JSON with a single "title" field.

Good examples:
{"title": "Fix login button on mobile"}
{"title": "Add OAuth authentication"}
{"title": "Debug failing CI tests"}
{"title": "Refactor API client error handling"}

Bad (too vague): {"title": "Code changes"}
Bad (too long): {"title": "Investigate and fix the issue where the login button does not respond on mobile devices"}
Bad (wrong case): {"title": "Fix Login Button On Mobile"}
