Security audit

Conversion Signal Qa

Security checks for vulnerabilities and agentic risk

Overview

This skill is a marketing measurement QA checklist/spec builder that uses user-provided analytics exports and only saves memory after explicit user approval.

Before installing, expect to provide GA4 traffic/conversion exports and possibly ecommerce/order data. Review the optional save prompt carefully, avoid including PII in UTMs or pasted exports, and use API connectors only if you deliberately want that convenience.

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
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
  • 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

Autonomous Decision Making

Excessive Agency
Confidence
75% confidence
Finding

Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.

## Save Results

After delivering, ask "Save these results for future sessions?" If yes, write the pre-flight report and the reusable UTM/event spec to `memory/ad/conversion-signal-qa/YYYY-MM-DD-<topic>.md`, promote signal-integrity blockers and the spec to `memory/hot-cache.md`, and add unresolved fixes to `memory/open-loops.md`. Do not write memory without asking.
