/install ntriq-x402-alt-text-batch
Description
Batch-generate WCAG-compliant alt text for up to 500 images in one call. Flat $3.00 USDC via x402.
Usage Guidance
Before installing or using this skill: (1) Clarify the apparent contradictions — ask the author whether inference is local or remote and how X-PAYMENT is generated and stored. (2) Treat image URLs and resulting uploads as potentially sensitive: do not send private or PII-containing images until you confirm the service's privacy policy and retention practices. (3) Request documentation or an SDK/example showing how to produce X-PAYMENT safely (ideally via a short-lived token or an env var the skill declares). (4) Test with a small non-sensitive dataset and confirm exact network behavior (does the endpoint fetch the images, or do you need to upload image bytes?). (5) If you require stronger guarantees, prefer a skill that documents authentication (explicit env var names) and does not claim contradictory execution modes (local vs remote).
Capability Analysis
Type: OpenClaw Skill
Name: ntriq-x402-alt-text-batch
Version: 1.0.0
The skill bundle consists of documentation for an API-based service that generates alt-text for images using the x402 payment protocol. It contains no executable code or malicious instructions, only standard API documentation for interacting with the endpoint https://x402.ntriq.co.kr/alt-text-batch. No evidence of prompt injection or unauthorized data access was found.

Capability Assessment
Purpose & Capability
Name/description (batch alt-text up to 500 images) align with the runtime instructions which call a remote API. However the SKILL.md also claims "100% local inference on Mac Mini," which contradicts the explicit POST to https://x402.ntriq.co.kr/alt-text-batch and payment flow — that's inconsistent.
Instruction Scope
The instructions require POSTing image URLs and an X-PAYMENT header to a third-party endpoint. That means image locations (and possibly image content if the service fetches them) and payment metadata will be transmitted externally. There are no instructions about how to build X-PAYMENT, how long it lives, or how to protect payment credentials. The SKILL.md does not instruct the agent to read local files or other system secrets, which is good, but it also lacks guidance about sensitive images or privacy.
Install Mechanism
Instruction-only skill with no install spec or downloaded code — lowest install risk.
Credentials
The service requires an X-PAYMENT header for a paid call, but the skill declares no required environment variables or primary credential. That mismatch is notable: a payment or signing secret is presumably necessary to call the API, yet the skill doesn't declare how that secret should be supplied or stored. No other unrelated credentials are requested.
Persistence & Privilege
always is false and the skill doesn't request persistent system privileges or modify other skills. Autonomous invocation is allowed (platform default) but not combined with other high privileges.
How to Use
