Cron Health Monitor

Security checks across malware telemetry and agentic risk

Overview

This cron repair skill appears purpose-aligned, but it can change and run scheduled jobs without clearly requiring user approval.

Review before installing if your cron jobs affect production, business records, or external systems. Use it for diagnosis freely, but require explicit approval before updating, running, disabling, or creating cron jobs, and keep backups or rollback notes for any changed schedules or payloads.

Findings (6)

Context-Inappropriate Capability

Medium

Confidence: 93% confidence
Finding: The playbook recommends modifying cron payloads to include shell execution (`exec(mkdir -p)`) and file-writing behavior, which expands the skill from health monitoring into operational command execution. This is dangerous because it normalizes a repair path that can alter the filesystem and job behavior without explicit safety constraints, increasing the chance of unintended system modification or abuse through prompt/payload tampering.

Context-Inappropriate Capability

Low

Confidence: 85% confidence
Finding: The playbook instructs writing department repair logs and escalating to the CEO, which extends the skill beyond core cron monitoring into organizational record modification and authority-routing. While not directly code-executing, these actions create unnecessary capability scope and persistent side effects that could be misused or triggered inappropriately by an automated repair workflow.

Vague Triggers

Medium

Confidence: 92% confidence
Finding: The trigger phrase 'fix cron' is broad enough to match ordinary troubleshooting requests, which can cause this skill to activate in contexts where the user did not explicitly intend automated cron analysis or repair. Because the skill includes update and auto-repair workflows, accidental invocation could lead to unintended changes to scheduled jobs or related files.

Missing User Warnings

Medium

Confidence: 95% confidence
Finding: The skill explicitly promotes automatic repair delegation and includes examples that update cron payloads, yet it provides no safety warning, approval gate, or change-management guidance before making impactful modifications. In a DevOps context, silent or semi-automated changes to cron jobs can disable business-critical automation, alter job behavior, or overwrite diagnostic outputs without the user's informed consent.

Missing User Warnings

Medium

Confidence: 91% confidence
Finding: The repair instructions direct operators to add command execution and file-writing steps without any warning that these actions can change the host environment or persist data. In a troubleshooting context, lack of impact disclosure makes risky changes appear routine, which increases the likelihood of unsafe execution and reduces operator scrutiny over potentially destructive side effects.

Missing User Warnings

Low

Confidence: 82% confidence
Finding: The playbook tells operators to write a repair log to persistent storage without warning that this modifies files and may affect organizational records. Although low severity, undocumented persistent writes broaden the operational footprint of the skill and can lead to accidental data handling or audit-trail issues.
