🟢 Trusted
No high-risk patterns surfaced by the deep scan — automated capability review, not behavioral proof.

A CTF solver orchestration skill that routes challenges to sub-skills (web, pwn, misc, reverse) and uses standard CTF tooling (pwntools, requests, gdb, radare2); its stated purpose of capturing CTF flags is a legitimate security competition activity.

⚠ Flagged for review — coarse, uncorroborated signal, not a confirmed exploit. Review the config yourself before installing.

Automated static analysis — not a human review. Caveat flags capabilities, not confirmed intent, and can produce false positives. Disagree with this verdict? Use Dispute below.
