Security checks for vulnerabilities and agentic risk

Overview

This skill estimates septic water use locally without accessing accounts, transmitting data, or changing your system.

Requires Python 3. Treat results as estimates and recheck any redistributed schedule. Follow the documented guidance to contact a septic professional for persistent slow drains or sewage backup.

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

Skill instructs the agent to omit warnings, disclaimers, or ethical commentary. Stripping safety caveats hides risk from the user and is a common jailbreak preamble.

## Why it matters

- Drainfield replacement is among the most expensive single-family repair outside the foundation; spacing water use is free.
- The failure is cumulative and invisible: bio-mat clogging gives no warning until slow drains, then soggy lawn, then backup.
- Guest weekends and laundry catch-up days are exactly when systems take their worst hits — and exactly when this tool earns its keep.
