E006: Malicious code pattern detected in skill scripts.
What this means
Detected high-risk code patterns in the skill content — including its prompts, tool definitions, and resources — such as data exfiltration, backdoors, remote code execution, credential theft, system compromise, supply chain attacks, and obfuscation techniques.
Why it was flagged
The file instructs executing remote install scripts via "curl ... | sh" and "irm ... | iex", which enables remote code execution and is a high-risk supply-chain / backdoor vector.
W013: Attempt to modify system services in skill instructions.
What this means
The skill prompts the agent to compromise the security or integrity of the user’s machine by modifying system-level services or configurations, such as obtaining elevated privileges, altering startup scripts, or changing system-wide settings.
Why it was flagged
The skill instructs running remote install scripts (curl ... | sh and irm ... | iex) and explicitly uses PowerShell's ExecutionPolicy ByPass, which directs the agent to bypass security mechanisms and modify the machine's state.
W012: Unverifiable external dependency detected (runtime URL that controls agent).
What this means
The skill fetches instructions or code from an external URL at runtime, and the fetched content directly controls the agent’s prompts or executes code. This dynamic dependency allows the external source to modify the agent’s behavior without any changes to the skill itself.
Why it was flagged
The skill's setup instructs fetching and executing remote install scripts at runtime (curl -LsSf https://astral.sh/uv/install.sh | sh and irm https://astral.sh/uv/install.ps1 | iex), so these URLs directly execute remote code required to install the dependency.
