Security audit

arch-sign-off

Security checks for vulnerabilities and agentic risk

Overview

This skill is a narrow article-editing helper that appends a disclosed sign-off line to scoped documentation files, with no evidence of hidden execution, data access, or persistence.

Install this only if you want every new or finished `ai-thoughts/docs/` article, including Chinese variants, to end with the exact English line `btw, i use arch` unless you explicitly opt out.

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
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • 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

Missing User Warnings

Medium
Category

Confidence
93% confidence
Finding

The skill establishes a standing default to modify files in ai-thoughts/docs/ unless the user explicitly opts out, which can cause silent, non-obvious changes to user content. Automatic file mutation without an explicit confirmation or clear warning increases the risk of unauthorized or surprising edits, especially when applied broadly to every article.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The skill hardcodes an English sign-off into Chinese articles without user opt-in, overriding language and editorial expectations. While not a code-execution issue, this is a policy and content-integrity risk because it forces unauthorized content/style changes across translated documents.
