Mindmap Generator

• Outcome: Review
• Latest audit: May 27, 2026 at 10:45 PM UTC
• Version:
  1.0.0

Overview

The skill does what it advertises, but it can send private conversation, calendar, memory, and meeting-note content to Telegram without a clear per-send consent or local-only option.

Install only if you are comfortable sending generated mindmaps, including possible meeting notes, priorities, calendar-derived context, or memory-derived context, through Telegram. Use a dedicated Telegram bot token limited to the intended chat, verify chat_id carefully, avoid regulated or confidential material unless Telegram is approved for that use, and prefer preinstalling a pinned Mermaid CLI instead of relying on runtime npx installation.

Vulnerability Patterns

• Data Exfiltration: External Transmission, Env Variable Harvesting, File System Enumeration
• Supply Chain: Unpinned Dependencies, External Script Fetching, Obfuscated Code
• 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

Findings (7)

Context-Inappropriate Capability

Medium

• Confidence: 96% confidence
• Finding: The script falls back to `npx -y @mermaid-js/mermaid-cli`, which can download and immediately execute code from the network at runtime. That behavior exceeds the core need of rendering a mindmap image and creates supply-chain and unexpected network-execution risk, especially if the package version changes or a compromised dependency is served.

Missing User Warnings

Medium

• Confidence: 93% confidence
• Finding: The README explicitly states that generated mindmaps are delivered through Telegram, which means conversation content, goals, decisions, or meeting notes may be transmitted to an external third-party service. Because the documentation does not clearly warn about this data flow, privacy implications, or data sensitivity, users may unknowingly send confidential information off-platform.

Missing User Warnings

Medium

• Confidence: 93% confidence
• Finding: The skill instructs the agent to transmit a rendered image based on conversation, memory, or meeting-note content to Telegram without an explicit warning or consent step. This is dangerous because mindmaps may condense sensitive personal, business, or meeting information and send it to an external messaging platform, creating privacy and data-handling risks.

Natural-Language Policy Violations

Medium

• Confidence: 91% confidence
• Finding: The skill's 'Always send the mindmap as a PNG image in Telegram' requirement forces a specific external channel regardless of user preference or sensitivity of the content. This increases risk by removing an opportunity to keep outputs local or text-only and can cause unnecessary disclosure of confidential material to Telegram infrastructure.

Missing User Warnings

Medium

• Confidence: 92% confidence
• Finding: The guidance explicitly encourages using memory and messages as fallback inputs for generating mindmaps, but it does not require user awareness, consent, or filtering for sensitive data. In a personal-assistant context, this can cause the agent to surface private conversations, calendar details, or stored personal information into an image or caption that the user did not expect, increasing the risk of privacy leakage.

Missing User Warnings

Medium

• Confidence: 90% confidence
• Finding: On render failure, the script sends the raw Mermaid input to Telegram as a text message without any user confirmation or redaction. That can leak sensitive conversation notes, goals, decisions, or priorities to an external service in a way that is less obvious than the normal image-delivery path, especially because failure handling often receives less scrutiny.

Missing User Warnings

Medium

• Confidence: 98% confidence
• Finding: The `npx -y` path performs automatic package download and execution without explicit notice or consent, so a normal render operation can unexpectedly trigger network activity and run newly fetched code. In an agent skill context, this is more dangerous because execution may occur in automation or server environments where users do not expect outbound fetches or dynamic code installation.
