Description
Fix grammar, spelling, and improve writing
Usage Guidance
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.
Capability Analysis
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.

Capability Assessment
Purpose & Capability
Name/description (grammar/spelling fixer) align with the SKILL.md and README: the skill calls an external NEXUS grammar-fix API and charges per request. Requiring a payment proof credential (NEXUS_PAYMENT_PROOF) is consistent with a paid external service.
Instruction Scope
Instructions are narrowly scoped to calling the external API (https://ai-service-hub-15.emergent.host) with payment headers. They do not request filesystem or shell access. However the runtime instructions explicitly tell the agent to include a payment proof header (which the skill declares as an env var) — that means a secret-like value will be transmitted to the external host as part of normal operation.
Install Mechanism
This is an instruction-only skill with no install spec or code to download, so nothing is written to disk by an installer. Lower risk from install mechanism.
Credentials
Only one required env var (NEXUS_PAYMENT_PROOF) is declared and is used to authorize payment. That is proportionate to a paid external API. It is nevertheless sensitive: the skill will send that value to the external service, so provide a least-privileged/payment-specific credential (or use sandbox_test for trials).
Persistence & Privilege
The skill does not request persistent/always-on privileges, does not modify other skills, and does not ask to write agent config. Default autonomous invocation is enabled (normal), but always:false limits forced inclusion.
How to Use
