Daily Digest

Security checks for vulnerabilities and agentic risk

Overview

This skill reads dated memory notes and writes a daily digest file, which matches its stated purpose and shows no hidden network, credential, destructive, or privilege behavior.

Install only if you are comfortable with the skill reading your dated memory notes and writing daily Markdown summaries under journals/digest. If you schedule it with cron, expect a new digest file to be created each day it runs.

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

Finding

The generated digest uses fixed French section titles such as "Résumé", "Décisions", and "Prochaines étapes". This enforces a specific language/locale in the skill's behavior, and the file does not indicate that the user can choose the language or that the French-only output is required for a documented regional context.

Missing User Warnings

Low
Category

Confidence
90% confidence
Finding

This markdown file explains that the skill saves a digest under journals/digest and can be scheduled via cron, but it does not include any explicit user warning about ongoing file creation or accumulation. Because markdown files should disclose behaviors that affect user data or system state, the missing warning about repeated file writes is a valid documentation gap.
