metaschedule is a skill for Claude Code, Codex from xvirobotics/metabot. It costs 61 tokens per session (1,158 once invoked), scanned A, original, MIT.

A persistent scheduler for running one-time delayed tasks or recurring cron tasks on a server. Cron is a standard format for specifying repeated times, such as every day or every Monday.

In plain words
What is it for?
Use it to add, list, pause, resume, or cancel delayed and recurring tasks with the MetaBot command-line tool.

  • medium Rogue Agent · line 26
    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.
  • medium Data Exfiltration · line 44
    Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.
    Fix: Verify the destination URL is trusted and necessary. Remove or replace with documented APIs. Ensure no secrets, tokens, or PII are transmitted.

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

metaschedule scanned grade A with 1 finding 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 11d 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.

MetaBot Scheduler

Persistent server-side scheduler. Use this when:

  • The schedule needs to outlive the current Claude session.
  • Another bot or operator may need to list, pause, or cancel it.
  • You want it to run inside MetaBot's PM2 process (not Claude's).

For ad-hoc, session-scoped scheduling, prefer the Claude Code native tools CronCreate and /loop instead — they're faster, in-process, and need no MetaBot server call.

Quick Commands (metabot CLI)

The metabot CLI is pre-installed and handles auth automatically.

# One-time delayed tasks
metabot schedule list                                       # List all scheduled tasks
metabot schedule add <bot> <chatId> <delaySec> <prompt>     # Schedule a one-time future task
metabot schedule cancel <id>                                # Cancel a scheduled task

# Recurring (cron)
metabot schedule cron <bot> <chatId> '<cronExpr>' <prompt>  # Create recurring task
metabot schedule pause <id>                                 # Pause a recurring task
metabot schedule resume <id>                                # Resume a paused recurring task

Cron format: minute hour day month weekday (5 fields). Examples:

  • 0 8 * * * → daily at 8am
  • 0 8 * * 1-5 → weekdays at 8am
  • */30 * * * *→ every 30 minutes Default timezone: Asia/Shanghai.

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.
