Daily Note Helper (Trial 2026-08-06)

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward daily note helper that writes local note files as part of its stated purpose, with no evidence of hidden, remote, destructive, or deceptive behavior.

Install this only if you want the agent to create and update local Markdown notes under `memory/` and possibly store durable facts in `MEMORY.md`. Review note contents before sharing the workspace because daily logs may contain sensitive work details.

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

Undeclared Tool Scope

Medium
Category
MCP Least Privilege
Confidence
93% confidence
Finding

The skill clearly instructs the agent to read and write files (memory/YYYY-MM-DD.md, MEMORY.md, and references/note-template.md) but does not declare any explicit tool scope such as allowed tools or path restrictions. This creates unnecessary ambiguity around filesystem access and can permit broader file operations than intended if the execution environment relies on declared scope for enforcement or review.

Missing User Warnings

Low
Category
Not specified by scanner
Confidence
92% confidence
Finding

This markdown file describes creating new daily note files, appending entries, and creating the memory/ directory if needed, but it does not explicitly warn the user that the skill will write to the filesystem. For markdown files, SQP-2 applies when behaviors affecting user data or system integrity are described without a user-facing warning.
