Security audit

tdd-spec

Security checks for vulnerabilities and agentic risk

Overview

This is a transparent TDD workflow skill with ordinary code-editing and test-running guidance, plus a non-security language preference issue.

Install this if you want a SPEC-driven TDD workflow and are comfortable with it asking questions and reporting progress in Portuguese. Expect it to modify project code/tests and run normal validation commands when you invoke it for implementation work.

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
Category
Not specified by scanner
Confidence
97% confidence
Finding

The description states that user-facing questions and recommendations must be in Portuguese (pt-BR), which imposes a fixed language policy. The rule allows locale constraints only when the user is given a choice or when the constraint is clearly documented and justified as region-specific, neither of which appears here.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
98% confidence
Finding

This line explicitly forces a specific language for all user-facing communication. That is a natural-language policy violation under the stated rules because it does not offer the user a language choice and does not justify the restriction as a region-specific requirement.
