DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Claude Code v2.1.119

Catch-Up Routine

What

A periodic ambient awareness system that checks on tracked priorities every 2 hours during work hours.

Details
  • Fires every 2 hours via cron (0 /2 )
  • Respects configurable quiet hours (default: 9am-5pm Mon-Fri) — silently exits outside that window
  • Maintains a persistent priority list in .claude/catch-up-state.json tracking: priorities, lastSnapshot, lastRunAt, and noiseFloor
  • On first run, bootstraps 2-3 priorities from CLAUDE.md and connected tools
  • For each priority: checks if state has changed since last snapshot across source control, chat, email, calendar, docs, and issue tracking
  • Triages findings into: assistant-can-act, user-should-act, FYI, or suppress
  • When calendar events are found, dynamically schedules one-shot /pre-meeting-checkin tasks 2-15 minutes before each event
  • If nothing is actionable, outputs "Nothing actionable." and the main agent won't relay it
  • Learns over time: promotes new items, prunes resolved ones, demotes unchanged items
Evidence

Catch-up routine (search for "catch-up-state.json", "/catch-up")

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
