Security audit

Feedback Controller

Security checks for vulnerabilities and agentic risk

Overview

This is a lightweight feedback and correction workflow skill with no code execution, data access, persistence, or hidden behavior.

Before installing, understand that this skill may be invoked automatically for correction or quality-control situations and may steer the agent into a six-part diagnostic format. It does not appear to run commands, access private data, install dependencies, or persist 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
Category
Not specified by scanner
Confidence
90% confidence
Finding

The trigger list includes generic conditions such as 'an output exists but does not meet the brief' and 'quality checks after writing, analysis, or workflow automation,' which could match many ordinary interactions. The file does not provide explicit exclusions or narrower constraints to distinguish when this skill should activate versus when a general response would suffice.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The skill enables allow_implicit_invocation without any visible trigger scope, allowlist, or contextual constraints. That makes it easier for the agent runtime to invoke this skill unexpectedly based on loose relevance matching, which can alter execution flow, override user expectations, or be abused by prompt-manipulation to route tasks into this controller when it was not explicitly requested.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
92% confidence
Finding

The manifest sets 'language: en', which indicates a fixed language preference. There is no accompanying opt-in, alternative language support, or justification that this skill must be English-only for a region-specific or compliance reason.
