Security checks for vulnerabilities and agentic risk

Overview

This skill contains no executable code, but its only instruction redirects users to another skill and asks the agent to delete the current skill.

Review this before installing or loading it as an agent skill. Treat the deletion and migration request as informational only unless you personally choose to remove the old skill and separately trust the replacement package.

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

Technical Analysis

The only instruction in the Skill attempts to change the agent's behavior by directing it to an externally hosted replacement and asking it to delete the current Skill. The deletion request is a destructive operation unrelated to a normal, inert deprecation notice.

The external resource is outside the audited package and may be updated independently after this review. Although the file does not itself retrieve or execute a remote payload, following its instructions could transfer trust to unaudited content. No scripts or direct mechanisms that automatically perform deletion, network retrieval, or code execution were present in the audited project.

Attack Path

  1. A user or agent loads SKILL.MD.
  2. The agent interprets the deprecation message as an operational instruction.
  3. The agent deletes the current Skill if it has sufficient filesystem permissions.
  4. The user or agent follows the external link and transfers trust to separately hosted, mutable Skill content.
  5. Any subsequent impact depends on the external content and the permissions granted to the agent; that content was not part of this audit.

Impact Assessment

Successful exploitation requires an agent that treats Skill text as authoritative and has permission to modify the Skill installation. In that context, the instruction could cause deletion of the local Skill and loss of its files or configuration. It may also move the user or agent to unaudited external instructions. No evidence establishes privilege escalation, persistence, automatic remote execution, ...[truncated 85 chars]

Remediation

Remediation Suggestions

  • Remove the instruction requesting deletion of the current Skill.
  • Replace the content with an inert deprecation notice that does not instruct an agent to perform filesystem operations.
  • Require explicit, informed user confirmation before deleting, replacing, downloading, or installing any Skill.
  • Present the replacement URL as informational text rather than an instruction that should be executed automatically.
  • Audit and pin the exact replacement package and version before recommending migration.
  • Restrict Skill execution contexts to least-privilege filesystem access so descriptive text cannot trigger unauthorized deletion.

Finding

The only user-facing text in the skill is written in Chinese and provides no alternative language or opt-in, which can violate a language/locale policy requiring user choice. There is no indication that the skill is region-specific or that the language restriction is justified.
