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.

Prompt capture

ScheduleWakeup tool description

27 model strings share this prompt, byte for byte.

1Schedule when to resume work in /loop dynamic mode — the user invoked /loop without an interval, asking you to self-pace iterations of a specific task.
3Pass the same /loop prompt back via `prompt` each turn so the next firing repeats the task. For an autonomous /loop (no user prompt), pass the literal sentinel `<<autonomous-loop-dynamic>>` as `prompt` instead — the runtime resolves it back to the autonomous-loop instructions at fire time. (There is a similar `<<autonomous-loop>>` sentinel for CronCreate-based autonomous loops; do not confuse the two — ScheduleWakeup always uses the `-dynamic` variant.) Omit the call to end the loop.
5## Picking delaySeconds
7The Anthropic prompt cache has a 5-minute TTL. Sleeping past 300 seconds means the next wake-up reads your full conversation context uncached — slower and more expensive. So the natural breakpoints:
9- **Under 5 minutes (60s–270s)**: cache stays warm. Right for active work — checking a build, polling for state that's about to change, watching a process you just started.
10- **5 minutes to 1 hour (300s–3600s)**: pay the cache miss. Right when there's no point checking sooner — waiting on something that takes minutes to change, or genuinely idle.
12**Don't pick 300s.** It's the worst-of-both: you pay the cache miss without amortizing it. If you're tempted to "wait 5 minutes," either drop to 270s (stay in cache) or commit to 1200s+ (one cache miss buys a much longer wait). Don't think in round-number minutes — think in cache windows.
14For idle ticks with no specific signal to watch, default to **1200s–1800s** (20–30 min). The loop checks back, you don't burn cache 12× per hour for nothing, and the user can always interrupt if they need you sooner.
16Think about what you're actually waiting for, not just "how long should I sleep." If you kicked off an 8-minute build, sleeping 60s burns the cache 8 times before it finishes — sleep ~270s twice instead.
18The runtime clamps to [60, 3600], so you don't need to clamp yourself.
20## The reason field
22One short sentence on what you chose and why. Goes to telemetry and is shown back to the user. "checking long bun build" beats "waiting." The user reads this to understand what you're doing without having to predict your cadence in advance — make it specific.
