Security audit

Deslop the Copy

Security checks for vulnerabilities and agentic risk

Overview

This is a writing-editing skill with clear, local instructions and no evidence of hidden access, persistence, data collection, or unsafe execution.

Before installing, understand that this skill will shape rewritten text aggressively around its style rules, especially its zero-em-dash rule. From a security standpoint, the reviewed artifacts are local, disclosed, and proportionate to a writing assistant skill.

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs
Vulnerability Patterns
  • Rogue AgentSelf-Modification, Session Persistence
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Session Persistence

Medium
Category
Rogue Agent
Confidence
60% confidence
Finding

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.

Wikipedia's [WikiProject AI Cleanup](https://en.wikipedia.org/wiki/Wikipedia:WikiProject_AI_Cleanup) maintains a detailed guide called [Signs of AI writing](https://en.wikipedia.org/wiki/Wikipedia:Signs_of_AI_writing), cataloging patterns observed across thousands of AI-generated texts. NPR, TechCrunch, and FlowingData have all covered it as the best reference for spotting machine-written prose.

Existing tools use these patterns to detect and strip AI tells from text: banned phrases, structural cliches, and sentence-level habits. Detection and removal are useful, but an aggressive rewrite can erase the person along with the slop.

deslop-the-copy preserves the writer's vocabulary, cadence, bluntness, humor, uncertainty, digressions, and formality. It makes the minimum effective edit, leaves strong human sentences alone, and never invents facts or opinions to sound more alive.

Skill Enumeration

Medium
Category
Agent Snooping
Confidence
80% confidence
Finding

Skill enumerates or reads other installed skills. Access to other skills' SKILL.md files or the skills directory reveals prompt instructions, capabilities, and secrets that should be invisible to peer skills.
