ScheduleWakeup: Cache-TTL-Aware Delay Guidance

What

The ScheduleWakeup tool's ## Picking delaySeconds instructions are now context-aware, giving different guidance based on the session's prompt-cache TTL.

Details
  • Sessions with a 1-hour TTL (Claude.ai subscriber sessions) receive guidance that ignores cache-window considerations — any delay in [60, 3600] is warm, so just pick based on what you're polling.
  • Sessions with the default 5-minute TTL receive the classic "don't pick 300s" guidance.
  • Sessions where the TTL is unknown receive a combined explanation covering both regimes.
Evidence

Context-aware delay guidance (search for "1-hour Anthropic prompt-cache TTL")

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