CAUTION

Publisher claims: "The AI-native operational layer for HubSpot. Free tier: 9 tools (5 GTM OS builders + 4 HubSpot audit tools — lifecycle stages, pipeline hygiene, AI readiness, property governance). Pro tier: live HubSpot revenue intelligence (RFM, ICP triangulation, pipeline health) gated by Lemon Squeezy." Observed in sandbox: no network, touches nothing outside the project, writes no memory.

KillerSkills ran it in the KillerSkills honeypot sandbox (2 scenarios) on 2026-10-27 and scored it 63/100 (Caution). It is not known to be malicious, but it has behaviour or code a security policy should decide on before install. Notable findings: Prompt injection; Prompt injection; Pipe-to-shell pattern. Summary: no network, touches nothing outside the project, writes no memory.
