大藏经CBETA2026
Security checks for vulnerabilities and agentic risk
Overview
This is a documentation-only CBETA scripture lookup skill with disclosed MCP knowledge-base use and no hidden code, persistence, or destructive behavior.
Installers should understand that this skill is meant for CBETA-based Buddhist text lookup and citation checking. Confirm before allowing it to edit documents through Tencent Docs or local docx tooling, and treat its Simplified Chinese corpus as a disclosed coverage limitation.
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

- Confidence
- 93% confidence
- Finding
The trigger list includes many broad, common Buddhist-domain terms, which can cause the skill to activate in conversations that only tangentially mention Buddhism. Over-broad invocation increases the chance of context hijacking, unnecessary tool use, and the model being steered into this skill when a narrower or safer skill would be more appropriate.

Natural-Language Policy Violations

- Confidence
- 87% confidence
- Finding
The file repeatedly describes the skill as a “简体版” resource and presents that locale choice as mandatory behavior, but does not offer the user a language/script choice or explain a justified locale restriction. This can violate language/locale policy when users may prefer or require Traditional Chinese for Buddhist source work.

Description-Behavior Mismatch

- Confidence
- 84% confidence
- Finding
The manifest and overview frame the skill as a precise CBETA scripture retrieval and quotation-verification tool using a single subscribed knowledge base. However, the deep-research section says to extract '古代注释 + 近现代学者观点', which goes beyond scripture/CBETA retrieval and citation checking into generalized research synthesis not justified by the stated single-source purpose.

Intent-Code Divergence

- Not specified by scanner
- Confidence
- 88% confidence
- Finding
The document states the skill uses the subscribed CBETA knowledge base as its only data source and does not automatically search the web. Elsewhere it instructs use of '近现代学者观点', CBETA online link generation, and even recommends other tools such as python-docx and Tencent Docs, which contradict the strict 'only data source' framing rather than merely omitting details.
