Description
Intelligent data quality checks and schema validation
Usage Guidance
This skill is a thin wrapper around a paid third-party API (ai-service-hub-15.emergent.host). Before installing: 1) Confirm you trust that domain and review its documentation. 2) Use the sandbox_test mode to verify behavior without payment. 3) Treat NEXUS_PAYMENT_PROOF as a secret — do not place private keys or wallet seeds there. 4) Be cautious about submitting signed Stellar XDRs to the sponsor endpoint (they may reveal transaction metadata). 5) If you want to avoid accidental charges, restrict autonomous invocation or require manual approval for any payment flow. If any of the above is unacceptable or the service/provider is unfamiliar, do not install.
Capability Analysis
Type: OpenClaw Skill
Name: nexus-data-validation
Version: 1.1.0
The skill is a legitimate interface for a third-party data validation API hosted at ai-service-hub-15.emergent.host. It follows a transparent HTTP 402 payment protocol for Cardano and Stellar blockchains and explicitly restricts its own permissions to network access only (disabling filesystem and shell access). No indicators of data exfiltration, malicious execution, or prompt injection were found.

Capability Assessment
Purpose & Capability
Name/description (data quality + schema validation) matches the SKILL.md and README: the skill forwards input to an external NEXUS data-validation API. The declared requirement (a payment-proof credential) aligns with the documented paywalled API behavior. Nothing required (binaries/config paths) is unrelated to the stated purpose.
Instruction Scope
The SKILL.md instructs the agent to POST inputs to a remote endpoint and to follow several payment flows (x402, MPP, legacy X-Payment-Proof). It does not direct filesystem access or shell execution. It does require contacting third-party endpoints (ai-service-hub-15.emergent.host) and, in the Stellar sponsorship flow, posting signed XDRs — which could reveal transaction details. These network actions are consistent with a paid external API but mean your data (and potentially payment metadata) will leave the agent.
Install Mechanism
No install spec and no code files — this is instruction-only. That minimizes local write/execution risk. There is no downloading of arbitrary archives or external installers.
Credentials
The skill requires a single environment variable: NEXUS_PAYMENT_PROOF (declared as primaryEnv). That is proportionate for a paywalled API. However, this value is a sensitive payment credential; users should ensure they do not store private keys or account secrets there. The SKILL.md also encourages posting signed Stellar XDRs to a sponsor endpoint — this is not expressed as an env var requirement but is sensitive operationally.
Persistence & Privilege
always is false and the skill is user-invocable; disable-model-invocation is false (normal). The skill does not request persistent installation-wide privileges or attempt to modify other skills or system config. Note: because the agent may invoke the skill autonomously, it could make paid requests if triggered — ensure you control invocation policies if unwanted charges are a concern.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install nexus-data-validation - After installation, invoke the skill by name or use
/nexus-data-validation - Provide required inputs per the skill's parameter spec and get structured output
