Obsidian Daily Note

• Outcome: Pass
• Latest audit: Sep 11, 2026 · 2:10 AM UTC
• Version: 1.1.0

Overview

This is a straightforward Obsidian daily-note helper that writes session summaries to a user-selected vault, with local persistence risks that are visible and purpose-aligned.

Install only if you want the agent to create or update Obsidian daily-note files from the current session. Before writing, confirm the vault path and review the proposed note content, especially if the conversation includes secrets, personal data, customer information, or work that syncs to a cloud-backed vault.

A.I.G

Vulnerability Patterns

• Skill Instruction Hijacking: Alters the agent's session goals or safety constraints when the skill loads
• Agent Memory Poisoning: Writes attacker-controlled rules into memory that affect later sessions
• Remote Payload Retrieval and Execution: Fetches external code whose behavior can change after review
• Embedded Malicious Code: Ships malicious scripts inside the skill and executes them locally
• Unauthorized Access and Privilege Escalation: Obtains permissions beyond the task's legitimate needs

Context Leakage

High

• Category: Data Exfiltration
• Confidence: 93% confidence

Finding

The phrase 'log session activities' encourages transferring conversational context into a persistent file, which creates a direct context-leakage path from the chat session into storage. This is especially risky because users may discuss credentials, internal project details, or other sensitive material during a session that should not be automatically memorialized.

# Obsidian Daily Note

Vague Triggers

Medium

• Category: Not specified by scanner
• Confidence: 91% confidence

Finding

The trigger phrases are broad enough to activate on ordinary requests like writing a summary or logging today's work, which can cause the skill to run in situations the user did not specifically intend. Because this skill performs file-writing behavior, overbroad activation increases the risk of unexpected persistence of user content into an Obsidian vault.

Missing User Warnings

Medium

• Category: Not specified by scanner
• Confidence: 88% confidence

Finding

The workflow instructs the agent to write a note into the user's vault, but the skill description does not clearly warn that it will create or modify files. Users may think they are only asking for a summary, while the skill persists data locally or into a synced vault, which can propagate unintended content across devices or services.

Ssd 3

Medium

• Category: Not specified by scanner
• Confidence: 95% confidence

Finding

The instruction to collect today's activities from session context and place them into a persistent daily note can capture sensitive information the user mentioned during the session but did not intend to store long-term. In an Obsidian vault, especially one synced via OneDrive, iCloud, or Obsidian Sync, this can turn transient chat context into durable, replicated data exposure.
