A scheduler for recurring agent tasks using Holix's built-in gateway. It runs tasks on a schedule for a selected profile, such as a daily report or weekly summary.

Use it to create and inspect scheduled tasks, verify that the gateway is running, and review job definitions and execution logs.

It automates repeated agent work without requiring operating-system cron jobs or custom scripts that run continuously. The gateway provides the execution environment and run history.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.

Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00025	$0.01296
Opus 5	$0.00013	$0.00648
Sonnet 5	$0.00005	$0.00259
Haiku 4.5	$0.00003	$0.00130

Security

Grade A, and why

holix-cron scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 135 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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

Gateway must be running (scheduler lives inside gateway):
- holix gateway start (background) or holix gateway start -f (foreground)
- holix gateway status — verify running
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 * * * *

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
