name	refer-chat
description	Fetch a specific past chat by timestamp. Triggers when the user pastes "refer-chat YYYY-MM-DDTHH:MMZ" — a minute-level ISO timestamp from their bookmarklet. Also triggers when the user asks how to install the chat timestamp bookmarklet or how to reference past chats precisely.

refer-chat

When the user pastes a timestamp

Example: refer-chat 2026-03-09T00:22Z

Action:

1. Call recent_chats(n=1, before="2026-03-09T00:22Z").
2. Check the result's updated_at — if it is within 2 minutes of the target timestamp, use it.
3. If the gap is larger than 2 minutes, the result is likely wrong due to a known backend pagination bug. Retry with recent_chats(n=10, before="2026-03-09T00:22Z") and pick the result whose updated_at is closest to (but before) the target timestamp.

Use the timestamp directly — it's already rounded up by the bookmarklet.

Bookmarklet setup

When the user asks about installation, read scripts/bookmarklet.js and guide them to create a bookmark with that code as the URL.

The bookmarklet extracts the current chat's updated_at from Claude.ai's React fiber tree, rounds up to the next minute, and copies refer-chat YYYY-MM-DDTHH:MMZ to clipboard. Works on claude.ai only.
