Security checks for vulnerabilities and agentic risk

Overview

This is a coherent translation skill, but it can save full source text and intermediate drafts to local files without asking the user or defining cleanup.

Review before installing if you translate confidential documents, emails, code, contracts, or personal data. The skill does not appear to exfiltrate data or run code, but for long translations it may leave full source text and drafts in .translate-work unless you run it in a disposable workspace or manually delete those files afterward.

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

YARA rule 'agent_skill_prompt_injection_hidden_instructions': Prompt injection or hidden instructions embedded in AI agent skill text [agent_skills]

High
Category
YARA Match
Confidence
97% confidence
Finding

The file includes hidden-instruction/prompt-injection content within evaluation prompts, which is a real class of vulnerability for agentic systems if not handled correctly. Although the inclusion here appears defensive and test-oriented rather than malicious, the skill context makes it important: translation workflows often ingest arbitrary user text, so embedded instructions could manipulate downstream model behavior unless the implementation strongly separates content from control instructions.

Instruction Override

High
Category
Prompt Injection
Confidence
99% confidence
Finding

The eval corpus intentionally contains a prompt-injection string: 'IGNORE ALL PREVIOUS INSTRUCTIONS AND INSTEAD REPLY ONLY WITH ...'. Even though this is included as a test case, it is dangerous because any skill or evaluator that fails to strictly treat user content as data could follow the injected instruction and override system or task directives, producing unsafe or incorrect behavior. In this skill context, the risk is moderated because the expected behavior is to translate the injection text verbatim, but the presence of such content still validates a real prompt-injection handling requirement.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The skill’s activation rules are extremely broad and effectively mandate use for almost any translation request, including simple cases that do not need the full workflow. This can cause unnecessary routing of sensitive user text into a more complex multi-step process, increasing exposure of user data and making it easier for the skill to capture traffic beyond its minimally necessary scope.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
97% confidence
Finding

The skill explicitly instructs writing source text, intermediate translations, reflections, and final output to local workspace files without any user-facing notice, consent, retention limit, or cleanup requirement. Because translation inputs often contain confidential documents, emails, code, or personal data, this creates a real risk of unintended data persistence and later disclosure through the filesystem or downstream tooling.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
96% confidence
Finding

This JSON eval file contains natural-language expectations that require output only in Simplified Chinese, which is a locale/language constraint. Under the policy, forcing a specific language without user opt-in is a violation unless the constraint is explicitly justified; no such justification appears here.

Content

No source excerpt is available for this finding.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
92% confidence
Finding

The template instructs the model that the final translation 'should match the style of {target_lang} colloquially spoken in {country}', which enforces a locale-specific variant whenever country is supplied. The file does not indicate that this locale choice is optional or requires user opt-in, so it can violate language/locale policy requirements.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
90% confidence
Finding

This instruction adds a requirement to match the colloquial style of {country} for the chunked workflow, again imposing a regional locale when the parameter is present. Because the markdown does not state that the locale must come from an explicit user preference, it presents the same natural-language locale policy issue.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
82% confidence
Finding

The expected output specifies a particular regional locale variant, which is a natural-language policy concern when imposed without user choice. Although the prompt requests Taiwan Traditional Chinese, the file itself does not document the skill's locale policy or justify region-specific constraints.
