holix-cron

When to use this skill

The user wants a recurring or scheduled task (daily report, hourly check, weekly backup summary, etc.).

Always use Holix built-in cron — jobs stored in the profile and executed by the gateway scheduler with the same agent stack as chat.

Do NOT

• Do not create or edit system crontab, launchd plists, or systemd timers for Holix agent work.
• Do not write standalone Python/bash “scheduler” scripts that loop with sleep unless the user explicitly needs OS-level scheduling outside Holix.
• Do not suggest third-party job runners when holix gateway can run the task.

Prerequisites

1. Gateway must be running (scheduler lives inside gateway):
   • holix gateway start (background) or holix gateway start -f (foreground)
   • holix gateway status — verify running
2. Jobs are per profile (--profile / HOLIX_PROFILE).

Storage (read-only for debugging)

• Jobs: ~/.holix/profiles/<profile>/data/cron/jobs.json
• Run log: ~/.holix/profiles/<profile>/data/cron/runs.log

Prefer commands below; edit JSON only if the user insists.

How to create a job

Tell the user the slash command (TUI / Telegram) or run CLI yourself if you have shell access.

Slash (chat):

/cron add <schedule> :: <task description>

Examples:

• /cron add every day at 9 :: Summarize yesterday's git activity
• /cron add every 30 minutes :: Check disk space and alert if >90%
• /cron add 0 9 * * 1-5 :: Morning standup prep from open issues
• /cron add hourly :: Quick health check of gateway

CLI (terminal):

holix cron add "every day at 9 :: Summarize logs"
holix cron list
holix cron disable <job-id>
holix cron enable <job-id>
holix cron remove <job-id>

Schedule formats

• Natural language (parsed automatically): every day at 9:00, every 30 minutes, hourly, daily, weekly, weekdays, every 2 hours
• 5-field cron (minute hour day month weekday): 0 9 * * *, */15 * * * *

Task text after :: is the agent prompt for each run (be specific: what to check, output format, workspace assumptions).

Manage jobs

Job IDs are short strings shown in the list (prefix match works).

TUI opens a modal with enable/disable/delete. Telegram has inline buttons under /cron.

Execution behavior

• Scheduler tick runs inside gateway (~30s); due jobs start in the background.
• Each run uses conversation id cron-<job-id> (separate from the user's chat session).
• The runner prepends context that this is an automated run; the model should complete the task and summarize results.
• Status fields: last_run_at, last_status (success / error / running), next_run_at, run_count.

Auto-creation from chat

Holix automatically creates a cron job when the user writes a recurring request in natural language (Telegram, MAX, TUI), for example:

• «Присылай мне новости по теме X каждый день в 10 утра»
• «Send me a summary every day at 9»

No /cron add needed for clear schedule + task phrasing. The host replies with job id and next_run_at. Gateway must still be running for execution.

You can also call the schedule_cron tool (schedule + task) when auto-detection did not fire.

Workflow for the agent

1. Clarify what should run and how often (timezone: server UTC for croniter unless user specifies).
2. Draft a clear task prompt (one-shot instructions, no “ask me later”).
3. Prefer schedule_cron tool or let the host auto-create; otherwise /cron add … or holix cron add "…".
4. Remind to start gateway if not running: holix gateway start.
5. After creation, suggest /cron list to verify next_run_at.

Natural language → user request

If the user says “every Monday at 10 run X”, translate to:

/cron add every week :: X

(or 0 10 * * 1 :: X if they prefer explicit cron).

• /init — one-shot project analysis, not periodic
• holix hub — skills/plugins, not scheduling
