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). The URL points to a personal GitHub repository that includes install/run scripts and instructions to execute code (node/bash), which makes it potentially risky because code from an unvetted individual repo can contain malicious payloads even though GitHub itself is a common hosting platform.
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 Phase 1 instructions (phases/01-install-claude-md.md) explicitly mandate running a script that downloads the canonical CLAUDE.md (with a GitHub raw fallback URL: https://raw.githubusercontent.com/Yeachan-Heo/oh-my-claudecode/main/docs/CLAUDE.md), and that externally fetched CLAUDE.md (which includes <remember> tags and configuration) is ingested and applied to agent/config behavior, so untrusted third‑party content can materially influence 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 flow can fetch the canonical CLAUDE.md at runtime (fallback: https://raw.githubusercontent.com/Yeachan-Heo/oh-my-claudecode/main/docs/CLAUDE.md), and that fetched README includes <remember>/context-persistence instructions that directly inject prompts/instructions into agent sessions while the skill requires that external content for installation—posing a high-risk remote-instruction dependency.
