02 / Compatibility

Scope: compatibility below is what each skill's own source states, not an independent test — True LLMs hasn't run these against live agents yet. Marked confirmed by source where the repo says so, untested everywhere else.

03 / Verification

No True Score yet — that requires actually running this skill against live agents, which True LLMs doesn't do today. What you see above is what the source states, last checked 2026-08-26.

Not a real-time signal you should rely on for security decisions — read the skill's own source before granting it any permissions.
