Security audit

Deep Thinking

Security checks for vulnerabilities and agentic risk

Overview

This skill is a plain Markdown reasoning guide with no code execution, data access, persistence, or hidden operational behavior.

Before installing, consider whether you want a broad reasoning-style skill to activate on many complex or ambiguous tasks. It appears operationally safe, but it may make responses more deliberative or verbose.

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
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access

Vague Triggers

Confidence

Finding

The skill description is written to auto-apply to a very wide range of situations such as multi-step problems, debugging, architectural decisions, ambiguous requirements, and any request to think carefully. That breadth can cause unintended invocation, increasing the chance this skill overrides more specific skills, adds unnecessary processing, or exposes users to behavior they did not explicitly request.

Missing User Warnings

Confidence

Finding

The skill explicitly instructs the model to produce 'inner monologue' style reasoning with examples of hidden deliberation phrasing. That creates risk of chain-of-thought elicitation or accidental exposure of internal reasoning, which can leak sensitive intermediate analysis, policy logic, or prompt details, especially in a deep-reasoning skill where users may probe for full thinking traces.

Autonomous Decision Making

Category
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.

- **Premature conclusions**: Settling on an answer before exploring alternatives
- **Overlooked alternatives**: Fixating on one approach because it's familiar
- **Logical inconsistencies**: Conclusions that contradict earlier findings
- **Unexamined assumptions**: Treating assumptions as facts without verification
- **Incomplete analysis**: Stopping at the first layer when deeper investigation is needed
- **Confirmation bias**: Only seeking evidence that supports your current theory
