Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed CONTRIBUTING.md generator that reads ordinary project configuration and writes one documentation file with overwrite confirmation.

Before installing, be aware that the activation phrases are broad, so review when the skill is invoked and confirm the generated CONTRIBUTING.md before accepting it, especially in multilingual repositories.

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

Vague Triggers

Medium
Category

Confidence
95% confidence
Finding

The skill description embeds multiple generic trigger phrases such as "init", "project init", and "initialize project", which are broad enough to match common user requests outside the narrow CONTRIBUTING.md generation use case. This can cause unintended activation of the skill in unrelated contexts, leading to overbroad repository analysis or file-generation behavior the user did not explicitly request.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
91% confidence
Finding

The trigger phrases are broad enough that normal user requests about contribution guidance could invoke this skill unexpectedly. Because the skill reads multiple project files and may write or overwrite CONTRIBUTING.md, accidental invocation can cause unintended file generation or prompt confusion, especially in larger agent workflows.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

Automatically matching the project language without explicit user choice can cause the skill to generate contributor documentation in a language the current requester did not intend. This is primarily an integrity and usability issue: it can lead to misleading or inaccessible documentation, especially in multilingual repositories or when project artifacts do not reflect contributor preferences.
