Pin the download to a specific version tag or commit hash. Verify the downloaded file's checksum before using it. Avoid piping curl output directly to a shell.

Likely FP if downloading from an official, well-known domain (e.g., deno.land, rustup.rs) with HTTPS, though this pattern remains risky even with trusted sources.

Replace direct shell script execution with a language-native implementation or a sandboxed executor. If shell scripts must run, restrict them to a vetted allowlist with integrity checks.

Likely FP if the match references running a script that is part of the skill's own repository (e.g., ./setup.sh) with clear, auditable contents.
