cron

cron is a skill for Claude Code, Codex from CES-Ltd/TitanX. It costs 21 tokens per session (1,524 once invoked), scanned A, original, Apache-2.0.

A guide for managing scheduled tasks that run operations automatically at specified times. It defines the required process for checking existing tasks, creating a task, and handling replacement or deletion.

In plain words
What is it for?
Use it to create, inspect, replace, or delete automated scheduled tasks while following the required confirmation and command format.
Why use it?
It prevents accidental duplicate schedules or deletion of an existing task. It also enforces a step-by-step workflow when task state or user confirmation matters.

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.

Security

Grade A, and why

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 5d 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.

Scheduled Task Skill

You can manage scheduled tasks to automatically execute operations at specified times.

IMPORTANT RULES

  1. ONE task per conversation - Each conversation can only have ONE scheduled task
  2. Query and WAIT for result - Before creating a task, output [CRON_LIST] and WAIT for the system to return the result
  3. NEVER combine commands - Do NOT output [CRON_LIST] and [CRON_CREATE] in the same message. Query first, wait for result, then decide.
  4. ASK before delete - If a task exists, you MUST ask the user whether to replace it or keep it. NEVER delete without user's explicit confirmation.
  5. ALWAYS include closing tags - [CRON_CREATE] MUST end with [/CRON_CREATE]
  6. Output commands directly - Do NOT wrap commands in markdown code blocks

Workflow for Creating a Task

CRITICAL: This is a multi-turn workflow. Do NOT skip steps or combine them.

Step 1: Query existing tasks (STOP and wait) Output ONLY [CRON_LIST] and nothing else. The system will return the current task status. DO NOT proceed to Step 2 until you see the system response.

Step 2: Review the result and ask user (STOP and wait for user response) After receiving the [CRON_LIST] result:

  • If "No scheduled tasks" → proceed to Step 3
  • If a task already exists → You MUST ask the user what they want to do:
    • Option A: Delete the existing task and create a new one
    • Option B: Keep the existing task and cancel creating a new one
    • NEVER delete the existing task without explicit user confirmation
    • Wait for the user's response before proceeding

Step 3: Execute user's decision

  • If user chose to replace: First delete the old task with [CRON_DELETE: <job-id>], wait for confirmation, then create new task
  • If user chose to keep: Do NOT create a new task, inform user the existing task is retained

Step 4: Create the new task (only if no task exists or user confirmed deletion) Only after confirming no task exists (or after successfully deleting), output the [CRON_CREATE] block.

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.
