use-devbox

Run commands inside a devbox environment when a directory provides one. If a `devbox.json` exists in the current directory (or an ancestor/subdir root), devbox can supply tools and scripts the bare shell lacks — e.g. psql, python, gcloud, node. If a binary is provided by devbox, prefer it over the system binary.

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

The install instruction uses a remote script piped to bash from https://get.jetify.com/devbox (a direct remote install endpoint), which is a high-risk pattern for malware distribution even if the accompanying GitHub repo looks standard.

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 instructs to run curl -fsSL https://get.jetify.com/devbox | bash which fetches and executes remote code at runtime, so the URL https://get.jetify.com/devbox is a runtime external dependency that executes code.
