Obsidian Cli Tool

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward Obsidian CLI command reference, with expected note-management and plugin-development capabilities but no hidden execution, persistence, or bundled code.

Install this only if you want an agent to help operate Obsidian through the Obsidian CLI. Before allowing delete, move, frontmatter removal, screenshot, DOM inspection, or plugin eval commands, make sure the target vault/note and intended change are explicit, because those actions can expose private vault content or change/delete notes.

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
Confidence
95% confidence
Finding
The skill description is broad enough to trigger on many ordinary note-taking or file-management requests, which can cause the agent to invoke a powerful skill in situations where the user did not explicitly ask for Obsidian-specific actions. Because the skill includes write, delete, and code-execution capabilities, over-broad routing increases the chance of unintended destructive actions or unnecessary exposure of vault contents.

Missing User Warnings

Medium
Confidence
92% confidence
Finding
The documentation advertises destructive operations such as moving and deleting notes without any warning, confirmation guidance, or backup/recovery advice. In agentic use, this raises the likelihood of accidental data loss because an automated system may treat those commands as routine and execute them without highlighting their irreversible or disruptive effects.
