Overview

This is a markdown-only workflow guide for safer long-running agent tasks, with disclosed checkpointing and no bundled executable code or hidden access behavior.

Safe to install as a workflow aid. For sensitive work, tell the agent where checkpoint files may be saved, avoid storing secrets in notes or screenshots, and review any subagent or external-system actions before they make changes.

Vulnerability Patterns

• Trigger Abuse: Overly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
• Prompt Injection: Instruction Override, Hidden Instructions, Exfiltration Commands
• Data Exfiltration: External Transmission, Env Variable Harvesting, File System Enumeration
• Privilege Escalation: Excessive Permissions, Sudo/Root Execution, Credential Access
• Supply Chain: Unpinned Dependencies, External Script Fetching, Obfuscated Code

Vague Triggers

Medium

• Confidence: 90% confidence
• Finding: The skill description is broad enough to trigger on many routine tasks, which can cause the agent to enter an expansive long-run workflow unnecessarily. In this context, that increases the chance of unnecessary file writes, subagent use, and external-system interaction beyond what the user likely intended, so the issue is a real safety and scope-control weakness even if not overtly malicious.

Missing User Warnings

Low

• Confidence: 82% confidence
• Finding: The skill instructs the agent to write checkpoint artifacts to disk but does not clearly require user awareness or consent before creating or modifying local files. In a long-running automation context, implicit disk writes can surprise users, overwrite existing workspaces, or leave sensitive intermediate artifacts behind, making this a real but relatively low-severity safety issue.
