plan-build-verify

This Bash snippet is a thin, non-obfuscated installer wrapper that delegates to npx to download and install an unpinned upstream npm package (gannonh/skills) with non-interactive confirmation. While the wrapper contains no direct malware logic or data-exfiltration code, it introduces meaningful supply-chain risk because integrity/version pinning and lockfile-based verification are not enforced at this layer; a compromised upstream package or registry resolution could execute harmful code during installation.

No intrinsic malware behaviors (network exfiltration, persistence, obfuscated payloads, or self-modifying/dynamic execution) are present in this module. However, it is inherently security-sensitive because it implements an arbitrary command execution harness driven directly by user-controlled CLI arguments, passes through the full parent environment, and persists untrusted stdout/stderr and argv/command strings verbatim to disk (logs and evidence.json). If an attacker can influence the CLI inputs or where evidence artifacts are stored/shared, this can lead to credential/secret exposure and high-impact misuse.
