 | **[Clawvisor](https://github.com/clawvisor/clawvisor)** | AI agent gateway for purpose-based authorization, credential vaulting, and audit logging — agents declare task scope, humans approve once, Clawvisor enforces on every request without the agent ever seeing credentials | [![GitHub](https://img.shields.io/github/stars/clawvisor/clawvisor)](https://github.com/clawvisor/clawvisor) |
 | **[trentclaw](https://github.com/trnt-ai/trent-openclaw-security-assessment)** | Security assessment skill for OpenClaw environments: scans gateway config, skill permissions, MCP trust boundaries, and plugins, and correlates them into chained attack paths with severity-ranked remediation steps | [![GitHub](https://img.shields.io/github/stars/trnt-ai/trent-openclaw-security-assessment)](https://github.com/trnt-ai/trent-openclaw-security-assessment) |
 | **[Nobulex](https://github.com/arian-gogani/nobulex)** | Trust Capital scoring layer for AI agents: bilateral Ed25519 receipts (pre- and post-execution signatures), content-addressed via action_ref and hash-chained per RFC 8785, that accumulate into a published 300-850 reputation score gating agent autonomy. CTEF v0.3.2 14/14 conformance. Python + TypeScript SDKs.
