Renderful AI

Generate images and videos via renderful.ai API (FLUX, Kling, Sora, WAN, etc.) with crypto payments. Use when the user wants to create AI images, videos, or needs a crypto-friendly generation service. Triggers: renderful, renderful.ai, generate image, generate video, crypto payment generation

Security Scan

The skill's instructions match its stated purpose (AI image/video generation) but the package metadata omits the sensitive environment variables the SKILL.md requests and the instructions explicitly encourage agent-held crypto payment credentials — a risky, unexplained combination.

Purpose & Capability

The name/description (renderful.ai image & video generation with crypto payments) aligns with the SKILL.md content: all API endpoints, models, and examples are consistent with that purpose. However, the skill metadata lists no required environment variables or primary credential even though the runtime instructions require an API key and optionally an agent wallet for x402 payments — this metadata omission is an inconsistency.

Instruction Scope

The instructions themselves stay focused on the renderful.ai API (generate, status endpoints) and do not instruct reading unrelated system files. The main concern is the explicit guidance to set an agent wallet (RENDERFUL_X402_WALLET) and to enable RENDERFUL_PREFER_X402 so "Agent can pay directly without human approval" — that gives the agent the ability to perform crypto payments if those env vars are present, which is a scope expansion beyond simple image generation.

Install Mechanism

This is an instruction-only skill with no install spec or code files; nothing is written to disk and no external packages are pulled. That reduces installation risk.

Credentials

The SKILL.md requires an API key (RENDERFUL_API_KEY) and optionally sensitive payment-related env vars (RENDERFUL_X402_WALLET, RENDERFUL_PREFER_X402). The registry metadata claims no required env vars or primary credential — this mismatch is concerning because sensitive crypto wallet credentials are implicitly requested but not declared. An agent wallet env var would grant on-platform autonomous payment capability, which is high privilege for a content-generation skill.

Persistence & Privilege

The skill is not forced-always and model invocation is allowed (default). While autonomous invocation by itself is normal, combining that with instructions to set an agent-held crypto wallet (and a flag to prefer x402 payments) materially increases risk: an autonomously-invoked agent with a funded wallet could make payments without explicit human approval. The skill also has unknown source/homepage which increases the risk of misuse.

What to consider before installing

The skill appears to do what it says (call renderful.ai to make images/videos) but the SKILL.md asks you to provide an API key and—optionally—an agent-held crypto wallet that lets the agent pay autonomously. Before installing: 1) Verify the skill's origin (there's no homepage/source listed). 2) Do not place a funded wallet (private key or wallet credential) in global agent env vars unless you fully trust the skill and platform; prefer a limited-spend or empty wallet. 3) Prefer manual approval for payments (do not set RENDERFUL_PREFER_X402=true or agent wallet env) unless you intend autonomous payments. 4) Create a dedicated renderful API key you can revoke, and monitor usage/transactions. 5) Ask the publisher to update registry metadata to declare required env vars explicitly. If you cannot verify the author or do not accept autonomous payments, consider not installing or using the skill without modifying its behavior to require human confirmation for any payment flow.

# Agent can pay directly without human approval
export RENDERFUL_X402_WALLET="your_agent_wallet"
export RENDERFUL_PREFER_X402="true"

Tips

• Use detailed prompts for better results
• Include style descriptors ("cinematic", "photorealistic", "anime")
• Negative prompts help avoid unwanted elements
• Check status for video generation (takes 30-120s)
