Currency Forecast

Security checks for vulnerabilities and agentic risk

Overview

This currency-analysis skill is purpose-aligned and does not show hidden, destructive, persistent, or credential-seeking behavior, though its claimed forecasting capability is overstated by the included stub script.

Install only if you are comfortable with currency-analysis requests potentially using external API and web-search services. Treat outputs cautiously because the included script does not currently perform real exchange-rate analysis or forecasting.

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

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
88% confidence
Finding

The skill exposes broad natural-language invocation examples like 'Analyze AUD/CNY exchange rate' and 'Check if AUD/CNY is below 4.82' without defining tighter activation boundaries or requiring explicit user confirmation before tool use. In agent ecosystems, this can cause over-triggering or accidental activation from conversational text, which may lead to unintended external API calls or web searches.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The skill states it uses Frankfurter API and web_search but does not warn users that their prompts, currency pairs, thresholds, or related context may be transmitted to third-party services. This creates a privacy and data-handling risk because users may unknowingly provide sensitive business, trading, or proprietary financial intent information that is sent externally.

Description-Behavior Mismatch

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The manifest describes a tool that provides technical analysis, market research, and predictive insights for currency pairs. In contrast, analyze_currency returns a static skeleton response with all analytical fields set to None, so the implemented behavior does not match the claimed capability.

Intent-Code Divergence

Low
Category
Not specified by scanner
Confidence
88% confidence
Finding

The comments suggest expected operational behavior—fetching exchange-rate data from an API—but the code immediately returns a stub object without any fetch or computation. This is an intent-code divergence because the documentation implies a behavior the implementation does not perform.
