Overview

This skill is a broad external API gateway that can process private content and send email/SMS/OTP messages, but its guardrails and disclosure are too thin for those high-impact actions.

Install only if you intentionally want a broad remote automation/API gateway, not just a project-context skill. Use a limited or test API key where possible, avoid confidential documents/audio or regulated data unless approved, and require manual review before any email, SMS, OTP, scraping, batch messaging, or smart-routed provider call.

Vulnerability Patterns

• Data Exfiltration: External Transmission, Env Variable Harvesting, File System Enumeration
• Excessive Agency: Unrestricted Tool Access, Autonomous Decision Making, Scope Creep
• Prompt Injection: Instruction Override, Hidden Instructions, Exfiltration Commands
• Privilege Escalation: Excessive Permissions, Sudo/Root Execution, Credential Access
• Supply Chain: Unpinned Dependencies, External Script Fetching, Obfuscated Code

Findings (32)

Context-Inappropriate Capability

Medium

• Confidence: 92% confidence
• Finding: The skill is presented as 'knowledge management' but also exposes outbound email and SMS/OTP actions, which materially expand its capability into external communications and account-verification workflows. That mismatch increases the risk of misuse for spam, phishing, unauthorized notifications, or social-engineering operations, especially because the documentation provides ready-to-run examples without any gating or justification tied to the stated purpose.

Scope Creep

High

• Confidence: 97% confidence
• Finding: The skill declares only Bash and Read as allowed tools, yet the documentation instructs network API calls and includes a file write (`curl ... -o sunset.png`). This creates a dangerous capability mismatch: operators or enforcement systems may underestimate what the skill does, while the examples encourage external transmission and local artifact creation beyond the declared scope.

Missing User Warnings

Medium

• Confidence: 95% confidence
• Finding: The documentation includes email sending and SMS verification flows but does not warn that these actions contact third parties, may message real users, and may process personal data such as phone numbers and email addresses. Absent notice and consent guidance, users may trigger privacy-impacting or irreversible outbound actions without understanding the consequences.

Missing User Warnings

Medium

• Confidence: 94% confidence
• Finding: The skill describes uploading audio, documents, search queries, URLs, and other user-provided content to external services for transcription, parsing, search, scraping, and media processing, but it provides no warning that sensitive content leaves the local environment. This omission can lead to unintentional disclosure of confidential data, regulated content, or proprietary materials to third-party providers.
