Security audit

update-readme

Security checks for vulnerabilities and agentic risk

Overview

This skill is a README-refresh workflow that reads repository context, researches examples, and edits documentation, with no evidence of hidden persistence, credential access, exfiltration, or destructive behavior.

Install this when you want an agent to revise README structure with repo inspection and web-based exemplar research. Review any external plugin dependencies separately, and invoke it explicitly for README updates because some trigger words are broader than the workflow itself.

A.I.G

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

Finding

Skill manipulates agent memory, state, or stored context. Memory corruption can alter personality, override safety rules, or cause unpredictable behavior.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The trigger list is broad enough to match common documentation-related requests such as 'readme', 'documentation', and 'structure', which can cause the skill to activate in situations beyond a narrowly intended README refresh workflow. Overbroad activation increases the chance of unintended tool use, unnecessary web research, or silent influence over unrelated documentation tasks, especially in agentic environments where triggers are used automatically.
