Prompt Optimizer

Security checks for vulnerabilities and agentic risk

Overview

This prompt-optimization skill is coherent and locally scoped, with no evidence of hidden execution, persistence, exfiltration, or destructive behavior.

Before using this skill, avoid putting API keys, passwords, personal data, regulated records, or confidential business material into prompts unless you intend that information to be processed by the model or downstream tools. The skill itself appears locally scoped and non-persistent.

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
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Anti-Refusal Statement

Anti-Refusal
Confidence
85% confidence
Finding

Skill instructs the agent to omit warnings, disclaimers, or ethical commentary. Stripping safety caveats hides risk from the user and is a common jailbreak preamble.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
90% confidence
Finding

The skill description uses very broad activation phrases such as 'improve, optimize, or analyze a prompt' and 'better clarity, specificity, or structure,' which can match a large share of ordinary user requests. In an agentic system, this increases the chance of accidental invocation, unnecessary access to user content, or routing conflicts where this skill intercepts requests not meant for it.

Missing User Warnings

Confidence
96% confidence
Finding

The Knowledge Injection section encourages users to supply domain-specific facts, including potentially proprietary information, but does not warn against pasting secrets, personal data, or confidential business material into prompts. In a prompt-optimization skill, this omission is more dangerous because users are explicitly being guided to enrich prompts with extra context, which can normalize unsafe disclosure of sensitive data to the model or downstream systems.

Vague Triggers

Confidence
84% confidence
Finding

The manifest description says the skill can "evaluate, optimize, and enhance prompts" but does not define specific trigger phrases, scope limits, or exclusion conditions. In a manifest file, this kind of broad capability wording can contribute to ambiguous or overly broad activation behavior if used for routing or invocation.

Missing User Warnings

Confidence
80% confidence
Finding

This markdown file describes techniques like Chain of Thought and later metacognitive prompting as generally applicable patterns, but it does not warn users that asking for detailed internal reasoning may be unsuitable in some environments or policy contexts. Because this is a user-facing reference file, a brief caution would help prevent misuse or misunderstanding of model behavior expectations.
