PromptArmor understands what a Skill can actually do, checks it against your organization's rules, and maps the connectors it reaches.
Capability-level understanding
We model what each Skill can do and flag when a capability breaks a rule your organization set.
Undeclared behavior
We surface the network calls, file reads, and endpoints that never appear in its SKILL.md.
Connector access mapping
We track every connector a Skill calls and the access it grants, read, write, or egress.
PromptArmor covers everything a Skill can do, then translates those findings into the business risk and the security risk.
What it can do
Every capability the Skill has, mapped to the systems and data it touches.
Business risk
What a compromise would actually put at stake for the business.
Security risk
The threats the Skill introduces, from prompt injection to data exfiltration.
Run the Skill in an isolated sandbox and watch what it really does: which files it reads, what it writes, and every network call it makes. PromptArmor maps observed behavior against what the SKILL.md declares.
