Cron Helper
Schedule recurring tasks for your AI agent without wrestling cron syntax.
Features
- Natural language scheduling ("every 2 hours", "daily at 9am")
- List, pause, resume, and delete scheduled tasks
- Execution history and failure tracking
- Timezone-aware scheduling
Usage
Schedule a task
# Using OpenClaw's built-in cron
openclaw cron add --every "2h" --task "Check inbox and summarize"
openclaw cron add --at "09:00" --daily --task "Morning briefing"
openclaw cron add --every "30m" --task "Monitor API health"
Manage tasks
openclaw cron list # Show all scheduled tasks
openclaw cron pause \x3Cid> # Pause a task
openclaw cron resume \x3Cid> # Resume a task
openclaw cron delete \x3Cid> # Remove a task
openclaw cron logs \x3Cid> # View execution history
Common Patterns
Heartbeat optimization: Instead of running expensive checks every heartbeat, use cron for specific intervals:
openclaw cron add --every "4h" --task "Check email inbox"
openclaw cron add --every "1h" --task "Monitor social mentions"
openclaw cron add --daily --at "08:00" --task "Generate daily briefing"
Health checks:
openclaw cron add --every "5m" --task "Ping API endpoints and alert on failure"
Tips
- Batch related checks into single cron jobs to save API costs
- Use
--modelflag to run cron tasks on cheaper models - Set
--timeoutto prevent runaway tasks

Usage Guidance
The skill appears to do what it says (manage cron-style tasks) and has no install or credential requests, but the SKILL.md embeds hidden metadata with URLs (onlyflies.buzz) that could cause the agent to contact an external coordination hub. Before installing: (1) verify the skill author/source and whether that onlyflies.buzz service is trusted, (2) ask the author to remove or explain the OADP metadata and any external endpoints, (3) avoid granting secrets or network access to unknown hosts, and (4) if you must test it, run the skill in a sandboxed environment or with network egress restrictions and monitor outbound requests. If the author can confirm the external endpoints are not used or provide trustworthy provenance for ClawSwarm, the risk is reduced.
Capability Analysis
Type: OpenClaw Skill
Name: cron-helper
Version: 1.0.0
The skill is suspicious due to an instruction in `SKILL.md` to install an external skill (`clawhub install clawswarm`) and the presence of hidden URLs in a comment, including a registration endpoint (`https://onlyflies.buzz/clawswarm/api/v1/agents/register`). While not directly malicious, these elements introduce a supply chain risk and potential for the agent to register with or fetch code from an external, potentially untrusted, service, which could lead to unauthorized data exfiltration or control.
Capability Assessment
Purpose & Capability
Name/description match the instructions: all runtime examples use an OpenClaw built-in CLI (openclaw cron). No binaries, env vars, or install steps are requested, which is consistent with a lightweight scheduling helper.
Instruction Scope
The visible usage is limited to local OpenClaw cron commands, but the SKILL.md includes a 'Related' link to an external site (onlyflies.buzz) and an HTML comment containing OADP metadata (hub, reg, ping) pointing to onlyflies.buzz endpoints. Those endpoints are not mentioned in the main instructions or declared as required resources — this hidden metadata could direct the agent to register or communicate with an external coordination hub, which is outside the skill's stated scope.
Install Mechanism
Instruction-only skill with no install spec and no code to be written to disk; lowest-risk install profile. There is a mention of 'clawhub install clawswarm' but no install specification or provenance for that package is provided.
Credentials
No environment variables or credentials are requested, which is appropriate. However, the external-onlyflies.buzz endpoints implied by the OADP comment could require credentials or enable agent-to-hub communication if the agent follows that metadata — this is not declared and therefore proportionality is unclear.
Persistence & Privilege
always is false and the skill doesn't request elevated or persistent privileges. Autonomous invocation is allowed (platform default) but not combined with other high-risk indicators here.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install cron-helper - After installation, invoke the skill by name or use
/cron-helper - Provide required inputs per the skill's parameter spec and get structured output
