Security audit

Skill Optimizer

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed, read-first skill audit tool that only recommends skill cleanup actions unless the user later chooses changes.

Install this if you want help auditing and cleaning up local skills. Expect it to inspect the current thread and visible skill directories, and review any proposed Fix, Merge, or Delete action before authorizing changes.

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
  • 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
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Vague Triggers

Medium

Not specified by scanner
Confidence
88% confidence
Finding

The manifest description says to use the skill whenever the user wants to "audit, optimize, clean up, consolidate, or improve" skill-related quality. These are broad, everyday terms and the file does not provide explicit trigger phrases, exclusions, or negative examples to limit when the skill should activate.

Vague Triggers

Confidence
85% confidence
Finding

The default prompt describes activation as auditing the current conversation and local skills, but it does not define specific trigger phrases, scope limits, or exclusion conditions. Terms like "audit" and "generate an actionable cleanup plan" are broad enough that the skill could be invoked for general review requests rather than a narrowly defined context.

Vague Triggers

Confidence

Finding

The prompt asks to audit 'current workspace' skills and infer missed triggers from conversation evidence, but it does not define clear activation boundaries or user-consent constraints. In a skill-routing system, broad language like this can cause over-triggering, unnecessary inspection of local skills, and expansion of scope beyond what the user explicitly intended.

Vague Triggers

Confidence
90% confidence
Finding

The request for a 'governance-style audit report' is ambiguous about whether it should analyze only the current thread, all installed skills, or broader local state. That ambiguity is risky because it can lead the skill to activate in contexts where the user did not clearly authorize broad inspection, increasing privacy and overreach concerns.

Vague Triggers

Category
Not specified by scanner
Confidence
89% confidence
Finding

The action-queue prompt uses very common operational language like 'fix, merge, delete, or keep and skip' without strong trigger specificity, which increases the chance that ordinary user requests could invoke this skill unintentionally. While the output is constrained, accidental activation could still steer users toward sensitive skill-management actions based on incomplete or incidental context.
