NEXUS Grammar Fix

Fix grammar, spelling, and improve writing

This skill is coherent with its stated purpose: it forwards text to a paid NEXUS grammar service and expects a payment-proof header. Before installing, verify you trust the endpoint (https://ai-service-hub-15.emergent.host) and the service terms. Use sandbox_test for trial runs instead of placing a real payment credential in NEXUS_PAYMENT_PROOF. If you must supply a real credential, use a payment-specific, revocable token (not a long-lived wallet private key) and be prepared to rotate/revoke it. If you need higher assurance, ask the publisher for formal documentation of the payment protocol, and validate the endpoints out-of-band. Confidence is medium because this is instruction-only (no code to audit) and the external host is not a widely-known vendor; access to the real service documentation or publisher identity would raise confidence.

Type: OpenClaw Skill Name: nexus-grammar-fix Version: 1.1.0 The nexus-grammar-fix skill is a wrapper for a third-party grammar-correction API hosted at ai-service-hub-15.emergent.host. It implements complex but legitimate blockchain-based payment protocols (x402, MPP, and Masumi) for Cardano and Stellar. The skill correctly limits its permissions to network access only, explicitly disabling filesystem and shell access in SKILL.md. While the documentation mentions non-existent future AI models (e.g., GPT-5.2), there is no evidence of malicious intent, data exfiltration, or prompt injection designed to compromise the agent.
