Agent Daily Planner

Security checks for vulnerabilities and agentic risk

Overview

This daily planner skill writes and updates local planning notes in disclosed paths, with no evidence of hidden execution or data theft.

Install this if you want an agent-managed local planning log. Be aware that commands such as `/plan today`, `/plan ship`, `/plan block`, `/plan week`, and `/plan priorities` can create or modify files under `memory/`, and `/plan priorities` overwrites that section for the current day.

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
Vulnerability Patterns
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep

Finding
The skill explicitly states that `/plan today` creates or updates `memory/YYYY-MM-DD.md` and that `/plan priorities` overwrites the "Priority Tasks" section, but it does not present a clear safety warning up front that user commands will write and overwrite local files. This can lead to unintended data loss or surprising file modifications, especially if an agent invokes the commands automatically without explicit user awareness.
