Orientation

Use when: scheduling a recurring or one-off remote agent run (cron-style, outside the current session). Don't use when: repeating work within the current session (use /loop); continuous unattended campaigns (use /daemon).

Default execution path (READ FIRST)

/schedule add does NOT call CronCreate by default. It shells out to node scripts/local-schedule.js which installs a native OS entry (Windows Task Scheduler or Unix cron). Only pass --remote to use Anthropic's routine system, and only after explicit user confirmation.

Why: CronCreate counts against the account-wide 15 routine runs / 24h cap; every fire of the scheduled task counts. See docs/ROUTINE-QUOTA.md.

Default flow — /schedule add "<expr>" "<command>" (no --remote)

Run:

node scripts/local-schedule.js add "<expr>" "<command>" --confirm

Before running, show the cadence, project, prompt and persistence and obtain approval to create the OS task. Normal Claude permissions remain enabled. Do not add a bypass flag to make unattended execution succeed.

Then report the returned ID and the removal command. This survives session end, machine reboot, and consumes zero routine quota. Use /schedule list and /schedule remove {id} (which also shell out to local-schedule.js) by default. Remove tasks before uninstalling. New jobs require their .citadel/schedules/<id>.json record; deleting it disables execution but leaves an inert OS entry. Existing jobs retain their old bypass flags until explicitly removed and recreated. See runner safety and migration.

Codex automation lane

When running in Codex and the user wants the schedule to survive the current terminal session, create a Codex Automation plan instead of a local OS entry:

node scripts/codex-automation.js plan --type schedule --cadence "<expr>" --command "<command>" --write

Give the returned prompt to the Codex app automation surface and keep the generated .planning/codex-automations/{id}.json as the durable Citadel record.

If .planning/ does not exist, create it before writing automation state.

Opt-in routine flow — /schedule add --remote ...

Only when --remote is explicitly passed:

  1. Confirm: "This will use CronCreate, which counts against your 15 routine runs / 24h quota and is cleared at session end. Continue? (y/N)"
  2. On confirmation, run the CronCreate-based flow documented below.

The rest of the protocol documents the full CronCreate flow for reference and for --remote invocations.

When to Route Here

  • "run pr-watch every hour"
  • "check my PRs automatically"
  • "schedule a thing"
  • "remind me to run tests every 30 minutes"
  • "set up a recurring task"
  • "list my scheduled tasks"
  • "cancel the PR check"
  • Any mention of "schedule", "recurring", "every N minutes/hours", "cron"

Protocol

/schedule list

List all currently scheduled tasks using CronList.

Output format:

Active schedules (N):
  [id] {description} — {cron expression} — next run: {time}

No schedules active.

If CronList is not available: output a helpful error (see Fringe Cases).


/schedule add "{description}" {/skill-or-command}

Create a recurring task.

Steps:

  1. Parse the user's description to extract:
    • Natural language interval: "every 30 minutes", "hourly", "every day at 9am"
    • The skill or command to run: /pr-watch, /do status, etc.
  2. Convert natural language to a cron expression (see Conversion Table below)
  3. Confirm with user: "I'll run {command} {natural-language-interval} (cron: {expression}). OK?"
  4. If confirmed: call CronCreate with the expression and command
  5. Output: "Scheduled. ID: {id}. Use /schedule remove {id} to cancel."

Cron Expression Conversion Table:

Natural LanguageCron Expression
every minute* * * * *
every 5 minutes*/5 * * * *
every 15 minutes*/15 * * * *
every 30 minutes*/30 * * * *
every hour / hourly0 * * * *
every 2 hours0 */2 * * *
every 6 hours0 */6 * * *
every day / daily0 9 * * * (default 9am)
every day at {H}am/pm0 {H} * * *
every weekday0 9 * * 1-5
every Monday0 9 * * 1

If the user provides a raw cron expression directly, use it as-is without converting. Validate it has 5 fields before accepting.


/schedule remove {id}

Remove a scheduled task by ID using CronDelete.

If the user doesn't know the ID: run /schedule list first, show the list, and ask which one to remove.

Output: "Removed schedule {id} ({description})."


/schedule status

Show all active schedules and their next run times. Equivalent to /schedule list with additional context about what each task does and when it last ran (if available).


Session-Scoped vs. Cloud-Persistent Scheduling

Session-Scoped (CronCreate)

CronCreate schedules tasks that run during the current Claude Code session only. When the session ends (Claude Code closes or the conversation is reset), all session-scoped schedules are cleared.

Use session-scoped when:

  • Running checks during an active work session ("remind me every 30min to commit")
  • Polling for PR feedback while you're at the computer
  • Triggering skill runs during a long coding session

Cloud-Persistent (RemoteTrigger)

For tasks that need to survive machine sleep, network drops, or session restarts, use RemoteTrigger — a one-off cloud trigger that fires from Anthropic's infrastructure rather than your local session.

Use cloud-persistent when:

  • The task needs to run overnight or while you're away
  • You want notifications when you return to your machine
  • The interval spans multiple days or calendar dates

How to set up a one-off cloud trigger:

  1. Call RemoteTrigger with the desired delay and the command to run
  2. Claude Code registers the trigger in Anthropic's cloud scheduler
  3. When the trigger fires, it wakes a new Claude Code session and runs the command
  4. Results are delivered as a notification

Note: RemoteTrigger requires Claude Code with cloud features enabled (Pro or Team plan). CronCreate works on all plans but is session-scoped only.


Fringe Cases

CronCreate not available: Output error; suggest OS cron/Task Scheduler. Never fail silently. Ambiguous interval: Ask for clarification before proceeding. Raw cron expression: Accept without conversion; validate 5 fields. Every-minute schedule: Warn about 60 fires/hour; suggest 5m or 15m instead. No schedules when listing: "No active schedules. Use /schedule add to create one." Pause requested: Explain pause isn't supported; remove and recreate instead.


Contextual Gates

Disclosure: "Creating schedule: {command} at {cron expression}. OK?" Reversibility: amber — creates OS cron entries or CronCreate sessions (side effects outside the repo); undo with /schedule remove {id} Trust gates:

  • Any: confirms before creating; shows cron expression before accepting

Quality Gates

  • Always confirm before creating (CronCreate is a side effect)
  • Always show the cron expression alongside the natural-language description
  • Always provide the ID after creation so the user can remove it
  • Never leave a user unable to remove a schedule they created

Exit Protocol

/schedule does not produce a HANDOFF block. After each action, output a concise confirmation or list and wait for the next command.

  • After add: "Scheduled. ID: {id}. Use /schedule remove {id} to cancel."
  • After remove: "Removed schedule {id}."
  • After list or status: the active schedule list (or "No active schedules.")
  • After any error: a clear message and actionable suggestion.
