Cron Helper

Security checks across malware telemetry and agentic risk

Overview

This skill is a transparent OpenClaw cron helper, but users should confirm scope and timezone before letting it edit scheduled jobs.

Install this if you specifically want help managing OpenClaw cron jobs. Before applying fixes, confirm which jobs will be changed, use the validation-backed or safe repair script, keep the generated backup, and replace Asia/Shanghai with the timezone you actually intend.

Vague Triggers

Medium

Confidence: 92% confidence
Finding: The activation description includes the catch-all phrase 'any time-based automation', which can cause the skill to trigger for a very broad set of unrelated requests. Over-broad routing increases the chance that users are pushed into cron-specific guidance when they did not ask for cron, leading to incorrect modifications of scheduler configuration or disclosure of cron-related operational details in the wrong context.

Vague Triggers

Low

Confidence: 81% confidence
Finding: Although the examples are concrete, the skill still lacks exclusion rules and boundary conditions, so ambiguous user requests may be interpreted as authorization to operate on cron jobs. In a skill that gives direct file paths and modification workflows for ~/.openclaw/cron/jobs.json, accidental activation can increase the risk of misconfiguration or unintended operational changes.
