Security audit

summarize-file

Security checks for vulnerabilities and agentic risk

Overview

This is a disclosed local-file summarization skill with no executable code, network behavior, or persistence, though its triggers and Write permission are broader than ideal.

Install only if you want the agent to read and summarize local documents. Provide explicit file paths or selected files, avoid directing it at sensitive documents unless needed, and treat any file writing as something that should require your clear request. Review the licensing text because the package metadata and document-level license scope are not fully aligned.

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
Vulnerability Patterns
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The trigger keywords are very generic terms like "summarize" and "file", which can cause the skill to activate in contexts far broader than intended. In a skill that reads local files, overbroad activation increases the chance of unintended file-access workflows being invoked from ambiguous user prompts, which can expand data exposure risk even without malicious intent.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The manifest embeds a long trigger list containing broad natural-language phrases such as '读文件', '文件摘要', and '这个文件讲了什么', which are common user utterances and can cause the skill to activate in situations broader than intended. Because this skill reads local files, accidental invocation increases the chance of unnecessary access to sensitive local content or misrouting user requests to this capability without sufficiently explicit intent.

Natural-Language Policy Violations

Low
Category

Confidence
85% confidence
Finding

This file begins with a Chinese-language licensing/scope notice, while the rest of the license is in English, and it does not offer any language or locale choice to the user. Under the stated policy, forcing a specific language without opt-in can be a natural-language policy violation unless the locale constraint is clearly documented and justified.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
79% confidence
Finding

The skill description is written entirely in Chinese even though the metadata lists many supported languages, and the document does not tell users they can choose their preferred language for interaction or output. This can be read as a language-policy issue because the natural-language presentation defaults to a specific locale without opt-in.
