What it does

Cron Scheduler is an agent skill from inbrainfun/inbrain. Schedule management with staggering, quiet hours, and wake-up override. Validates schedules, prevents collisions, and gates delivery during quiet hours.

Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Productivity & Automation, covering Scheduled and recurring tasks.

When your agent uses it

  • Tasks that involve Scheduled and recurring tasks

Example prompts

  • “/cron-scheduler”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Define job. Name, schedule (cron expression), skill to run, timeout.
  2. Validate schedule. Check no collision with existing jobs (5-minute offset rule).
  3. Check quiet hours. Default: 11 PM - 8 AM local time.
  4. Register with host scheduler. OpenClaw cron, Railway cron, crontab, or process manager. Each registered entry should execute via Minions…
  5. Write thin prompt. Job prompt is one line: "Read skills/{name}/SKILL.md and run it."

What it can do on your machine

Read from SKILL.md and the folder at commit 5231990. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are cron).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Cron Scheduler loads about 1k tokens when it runs. Until then it costs about 42 tokens; SKILL.md has 498 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~42
When it runs · the whole SKILL.md, loaded when a task matches
~1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 498 words (~1,046 tokens).
