Agent Daily Report (EN)

Security checks for vulnerabilities and agentic risk

Overview

This skill only instructs the agent to create honest daily work summaries from its own activity records, with no code execution or hidden access behavior found.

Before installing, consider whether daily reports may summarize sensitive session details such as files changed, retrieved information, or decisions. Use it where that reporting is appropriate, and ask for a different language or schedule if English or the default 21:00 America/Los_Angeles timing does not fit.

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

Natural-Language Policy Violations

Medium
Confidence
97% confidence
Finding
The skill name includes an explicit English locale suffix and the description/instructions specify a professional report format in English without indicating that users may choose another language. This creates a language-policy issue because the skill appears to enforce a specific language by default rather than offering user choice or documenting a justified locale restriction.

Natural-Language Policy Violations

Medium
Confidence
93% confidence
Finding
The manifest description says this is an "English self-reporting skill," and the skill name also encodes "-en," which indicates a fixed language constraint. For manifest files, this is a natural-language policy concern when a specific language is imposed without stating that the user can choose or opt in to that locale.
