Scheduled Voice Briefing

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed voice-briefing configuration and example package with no evidence of hidden execution, credential use, network access, or persistence.

Install only if you want a configuration-and-example skill for voice briefing workflows. It does not provide a complete scheduler, voice engine, calendar/weather connector, or TTS provider, so review any runtime integration that supplies those capabilities separately.

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

Findings (8)

Tp4

High

Category: MCP Tool Poisoning
Confidence: 98% confidence
Finding: The skill description promises broad scheduling, task lifecycle management, and constrained data access, but the referenced implementation appears to do much less and still performs local file access via configuration input. This mismatch is dangerous because users or orchestrators may grant trust, permissions, or invoke the skill under false assumptions, increasing the risk of over-privileged deployment or unintended local data handling.
Content: No source excerpt is available for this finding.

Undeclared Tool Scope

Medium

Category: MCP Least Privilege
Confidence: 70% confidence
Finding: Without declared permissions the skill's intent is opaque and cannot be validated.
Content: No source excerpt is available for this finding.

Vague Triggers

Medium

Category: Not specified by scanner
Confidence: 90% confidence
Finding: The invocation text is very broad and covers many generic reminder, briefing, and configuration scenarios, which can cause the agent framework to activate this skill in situations beyond its real capabilities. Unintended activation can route user requests to a mismatched skill, causing incorrect handling of scheduling, privacy expectations, or downstream integrations.
Content: No source excerpt is available for this finding.

Natural-Language Policy Violations

Medium

Category: Not specified by scanner
Confidence: 95% confidence
Finding: The script embeds Chinese weekday names, weather descriptions, and briefing text templates, causing output to be produced in Chinese by default. This is a natural-language locale constraint with no user opt-in or configurable language selection visible in the file.
Content: No source excerpt is available for this finding.

Natural-Language Policy Violations

Medium

Category: Not specified by scanner
Confidence: 94% confidence
Finding: The default config sets the speaker language to "zh", which imposes a specific locale by default. Under the policy, forcing a language without user choice or clear region-specific justification is a natural-language policy violation.
Content: No source excerpt is available for this finding.

Natural-Language Policy Violations

Medium

Category: Not specified by scanner
Confidence: 96% confidence
Finding: The command-line interface defaults --language to "zh", meaning the skill will select a specific language unless the user overrides it. This is a locale-policy issue because no opt-in or documented justification is provided.
Content: No source excerpt is available for this finding.

Natural-Language Policy Violations

Low

Category: Not specified by scanner
Confidence: 83% confidence
Finding: The document is structured throughout as combined English/Chinese briefing guidance and examples, which can imply that generated briefings should include both languages by default. Because the file does not state that language choice is user-selectable or context-dependent, it risks violating a language/locale policy requiring user opt-in.
Content: No source excerpt is available for this finding.

Natural-Language Policy Violations

Low

Category: Not specified by scanner
Confidence: 84% confidence
Finding: This markdown file includes a natural-language/config example that sets "language": "zh" as the speaker language. Because the document does not indicate that language is user-selectable or that Chinese is merely one optional example, it can be read as prescribing a specific language without user opt-in.
Content: No source excerpt is available for this finding.
