Critical
Do not install without reviewing
Security
3 findings: 2 critical severity, 1 medium severity. Installing this skill is not recommended: please review these findings carefully if you do intend to do so.
E005: Suspicious download URL detected in skill instructions.
What this means
Detected a suspicious URL in the skill instructions that could lead the agent to download and execute malicious scripts or binaries. This includes links to executables from untrusted sources, typosquatting of official packages, URL shorteners that obscure the destination, and personal file hosting services.
Why it was flagged
Multiple entries are GitHub repositories and a personal download page hosting offensive EDR-bypass/PoC tools from low-reputation or clearly offensive handles (and a non-official executable host), which are high-risk download sources that could be used to distribute malware.
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 content is explicit offensive red-team tooling and playbooks describing EDR bypass (AMSI/ETW patching, ntdll unhooking/indirect syscalls/HWBP, PPID spoofing, implant/beacon callback, LSASS dump), which enable backdoors, remote code execution, credential theft and system compromise.
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
This skill explicitly instructs the agent to bypass EDR protections and modify system-level telemetry and binaries (AMSI/ETW/ntdll/kernel callbacks), and to run/install tooling and deployment actions that change the host's security state and require elevated privileges.
Low
Low-risk findings.
1 low severity finding. Worth noting, but not necessarily harmful.
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
I flagged https://github.com/klezVirus/SysWhispers3 because the skill explicitly instructs to "git clone https://github.com/klezVirus/SysWhispers3" and run its Python script at runtime (references/unhook-techniques.md:63-66 and SKILL.md:174), which fetches and executes remote code that the skill relies on.
