Delay
Schedule the given instructions to fire exactly once at a future time in this session. Scheduling is the entire task of this turn — do NOT start executing the instructions now, even partially. That is the failure mode this skill exists to prevent: the task running immediately AND again at fire time.
Arguments: $ARGUMENTS
Steps
Parse arguments. Split at the first comma: everything before it is the time spec ("1 hour later", "in 30 min", "at 16:30", "tomorrow 9am"), everything after is the instructions to run later (pass through verbatim — including slash commands like
/x-wt-teams foo bar). If either part is missing or the time spec is ambiguous, ask instead of guessing.Compute the fire time. Run
date '+%Y-%m-%d %H:%M'for the current local time, then compute the target:
- Relative spec → add the delta to now.
- Absolute spec already past today → assume the next occurrence (tomorrow).
- Handle rollover: adding hours may cross midnight or month boundaries — the pinned day/month must match the actual target date.
- Create exactly one job with the CronCreate tool:
cron: fully pinned"M H DOM MON *"for the target time. Use the exact computed minute — don't round to :00/:30 (the harness fires those up to 90s early, and round marks cause fleet-wide load spikes).recurring: false. This makes the job auto-delete after firing. A recurring job (the default) stays alive and can fire again — the double-invoke bug.prompt: prefix the instructions so the future turn knows it is a scheduled firing, not a fresh request to schedule:[One-shot task scheduled earlier via /delay, firing now as planned. Do not reschedule or delay again — execute directly:] <instructions verbatim>
- Confirm to the user (and stop — no other tool calls after this):
- The exact fire time and job ID (cancelable via CronDelete by ID).
- The session must stay open — the job is in-memory and dies silently if Claude Code exits.
- The job fires only while the session is idle, so it may start a bit late if work is in progress at the target time.
Guardrails
- Exactly one CronCreate call per /delay invocation. Don't add wakeups, loops, or Monitor tasks alongside it.
- Never run any part of the instructions in the scheduling turn — not even "harmless prep" like a git pull.
- If the user actually wants a recurring cadence, hand off to /loop; if they need it to survive terminal close, hand it off to a cloud Routine (the Claude Code Remote
create_trigger/send_laterMCP tools), which persists server-side instead of dying with the session.
