Security checks for vulnerabilities and agentic risk

Overview

The skill is mainly a podcast downloader, but its routing text is much broader than its real purpose and could cause agents to use command and file-write tools in unrelated coding tasks.

Review before installing. Use this only for Xiaoyuzhou podcast downloads, set PODCAST_DIR to a directory you control, and do not rely on its broad coding/debugging/deployment routing text. The package also references files that are not included, so expect manual setup or missing-command failures.

Description-Behavior Mismatch

Medium
Category
Not specified by scanner
Confidence
94% confidence
Finding

The manifest describes a narrowly scoped podcast downloader, but the invocation text repurposes it for broad coding, debugging, and deployment tasks. This scope mismatch can cause an agent to select and run a skill with Bash/Write/Edit permissions in contexts unrelated to podcast downloading, increasing the chance of unintended command execution or file modification.

Vague Triggers

High
Category
Not specified by scanner
Confidence
96% confidence
Finding

The trigger keywords are overly broad and ambiguous, including generic terms that can match unrelated user requests. In an agent ecosystem, this can cause over-selection of a skill that has Bash, Read, Write, and Edit capabilities, making accidental execution in the wrong context significantly more dangerous than a mere documentation error.

Vague Triggers

High
Category
Not specified by scanner
Confidence
97% confidence
Finding

The invocation conditions claim the skill should be used for broad software-development tasks even though its real behavior is a specialized downloader. This materially increases the risk of agent misrouting: the skill may be invoked during unrelated requests and then perform network access, shell execution, and filesystem writes outside the user's expected workflow.
