Security checks for vulnerabilities and agentic risk

Overview

The skill is not malicious, but it needs review because it can send profile and chat data and perform social actions through an arbitrary external API without clear consent safeguards.

Install only if you trust the social API endpoint you will configure. Review SOCIAL_API_BASE before use, avoid sending unnecessary personal or recovery information, store tokens securely, and require confirmation before the agent sends messages, likes profiles, changes relationships, or runs daily maintenance actions.

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

Intent-Code Divergence

Medium
Category
Not specified by scanner
Confidence
76% confidence
Finding

L041-L042 explicitly state that batch operations and multi-agent coordination are not available in the free version. Elsewhere, the generic capability text presents the skill as supporting broad operational modes such as create/query/export and modify/reset/import without tying them to the documented free-version limits, creating contradictory intent signals in the documentation.

Description-Behavior Mismatch

Medium
Category
Not specified by scanner
Confidence
89% confidence
Finding

The manifest and surrounding documentation describe a limited free social-networking toolkit focused on registration, matching, swiping, chat, notifications, and relationship management. However, the generic sections at L052, L060, and L068 claim support for broader create/query/export, modify/reset/import, and export/save/convert operations, which are not part of the declared free-edition feature set and suggest extra functionality not justified elsewhere in the file.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The skill declares an overly broad activation scope using a long keyword list with generic terms such as 'Use', 'when', 'LLM', and similar catch-all phrases. This increases the chance the skill is invoked in unrelated contexts and may cause an agent to perform external social-network actions or data handling when the user did not intend to use this skill.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
94% confidence
Finding

The skill instructs the agent to transmit sensitive profile, personality, interest, chat, and relationship data to an external API without a clear user-facing consent, privacy notice, or trust-boundary warning. In an agent setting, this can lead to silent disclosure of behavioral and personal data to third-party services, especially if the agent auto-executes curl commands via exec-enabled workflows.

External Transmission

Medium
Category
Data Exfiltration
Confidence
96% confidence
Finding

The skill explicitly directs external transmission of detailed agent profile data, including personality traits, interests, bio text, and potentially recovery email, to a remote API endpoint. In this context the transmission is core functionality, but it remains security-relevant because the skill has exec capability and does not enforce user confirmation, endpoint validation, or data minimization before sending potentially sensitive information off-platform.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
83% confidence
Finding

The visible natural-language description and operational guidance are entirely in Chinese, with no indication that users may choose another language or locale. Under the stated policy, forcing a specific language without opt-in is a natural-language policy issue unless clearly justified as region-specific.
