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
Suspicious download URL detected (high risk: 0.70). This is a personal GitHub repository (unknown maintainer) that instructs running shell/install scripts from the repo—GitHub is better than anonymous file hosts but executing unvetted scripts from a low-profile account poses a meaningful malware/compromise risk.
W011: Third-party content exposure detected (indirect prompt injection risk)
What this means
The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.
Why it was flagged
Third-party content exposure detected (high risk: 0.90). The skill's Phase 1 explicitly instructs downloading and installing CLAUDE.md from a public GitHub raw URL (fallback: https://raw.githubusercontent.com/Yeachan-Heo/oh-my-claudecode/main/docs/CLAUDE.md) and also queries public npm/GitHub APIs, and the fetched CLAUDE.md (which includes context-persistence/<remember> tags) is installed and used to configure agent behavior — so untrusted third‑party content can be read and materially change the agent's actions.
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
Potentially malicious external URL detected (high risk: 0.90). The setup explicitly falls back to downloading the canonical CLAUDE.md at https://raw.githubusercontent.com/Yeachan-Heo/oh-my-claudecode/main/docs/CLAUDE.md during runtime, and that fetched file contains CLAUDE configuration and <remember>/prompting instructions that directly control agent behavior, making it a required external dependency.
