Why this score

This repo hosts 31 subagents, so its 41,963 stars are split between them (about 1,354 each) for scoring.

Security

Scanned Oct 21, 2026 at commit 0e0115935db9, with Cisco's open-source skill-scanner.

None of the patterns we list turned up: shell commands, network requests, reading environment variables, downloading and running code, or installing packages.

A scan lists patterns in the code. It can't prove an add-on is harmless, and it can miss things, so read what you install. How we scan
