Nano Banana Image Workflow Helper

Security checks for vulnerabilities and agentic risk

Overview

This is a documentation-only image workflow helper with some overly broad trigger metadata but no evidence of data access, code execution, persistence, or destructive behavior.

Installers should be aware that the skill may activate more often than intended in environments that honor the broad Chinese trigger metadata or implicit invocation. Its actual behavior is limited to producing image-workflow guidance, prompts, QA checks, and retry plans.

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

High
Category
Not specified by scanner
Confidence
97% confidence
Finding

The trigger keyword list is excessively broad, including generic terms like "nano", "banana", "pro", "generate", "edit", and "images" that commonly appear in ordinary user requests. This can cause unintended activation of the skill, leading to prompt-routing hijacks, inappropriate context injection, and unreliable agent behavior when unrelated tasks are misclassified as matching this skill.

Vague Triggers

High
Category
Not specified by scanner
Confidence
98% confidence
Finding

The trigger sentence begins with a very broad everyday phrase ('Help me ...'), which can cause the skill to activate during ordinary conversation even when the user did not intend to invoke this specific skill. In an agent environment, unintended invocation can misroute tasks, override more appropriate skills, or cause workflow execution on irrelevant inputs, reducing reliability and potentially exposing downstream systems to unnecessary processing.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
92% confidence
Finding

The invocation description says to use the skill when users mention broad terms or need general practical support around the demand, but it does not clearly bound what requests are in-scope. This ambiguity increases the chance that orchestration logic will activate the skill for loosely related prompts, causing overreach, incorrect tool selection, and accidental insertion of unrelated workflow guidance into normal conversations.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
91% confidence
Finding

The example trigger phrases are written as broad natural-language requests that resemble ordinary user speech and repeat generalized demand statements rather than precise invocation patterns. This trains or encourages matching systems to fire on common phrasing, which can amplify false positives and make the skill easier to trigger accidentally across unrelated requests.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
89% confidence
Finding

The skill enables implicit invocation without any visible trigger constraints, scoping rules, or confirmation requirements. That increases the chance the agent will auto-select this skill in loosely related contexts, causing unintended prompt-generation behavior, possible context leakage into the skill, and expanded attack surface for prompt-injection or workflow manipulation.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

This trigger remains overly generic ('I need a practical workflow ...') and lacks specific conditions that distinguish intentional invocation from normal user requests. Because the skill is a general productivity helper, broad matching makes accidental activation more likely and increases the chance that unrelated user prompts are captured by this skill instead of a safer or more suitable one.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
88% confidence
Finding

The entire skill description is written only in Simplified Chinese, including the title and usage guidance, with no indication that users may choose another language or locale. This can violate language-choice policy when a skill implicitly constrains interaction to one language without explicit opt-in or justification.
