安全使用建议
This skill appears to do what it says: call pdfapihub.com to convert PDFs to images. Before installing, consider: (1) Privacy — PDFs you convert (possibly containing sensitive data) will be uploaded to a third‑party service; check pdfapihub.com's privacy policy and retention rules. (2) API key handling — the skill expects a CLIENT-API-KEY but the registry metadata doesn't declare how you'll supply it; confirm how your agent will store/provide the key securely. (3) Trustworthiness/provenance — source and homepage are missing; if you need guarantees, validate the service independently (domain, documentation, reputation). (4) Alternatives — if you must keep documents local, use a local tool (poppler/muPDF/ImageMagick) instead of an online API. If any of these are unacceptable, do not install or use the skill until you verify the provider and key storage.
功能分析
Type: OpenClaw Skill
Name: pdf-to-image
Version: 1.0.0
The skill is a standard API wrapper for a third-party PDF conversion service (pdfapihub.com). Its functionality, as defined in skill.json and SKILL.md, is limited to sending PDF data (via URL or base64) to a remote endpoint for image rendering. No evidence of malicious intent, prompt injection, or unauthorized data exfiltration was found.

Purpose & Capability
Name/description match the instructions and skill.json: the skill calls https://pdfapihub.com/api/v1/convert/pdf/image to convert PDF pages to images. No unrelated binaries, credentials, or platform components are requested.
Instruction Scope
SKILL.md instructs posting PDFs (by URL, base64, or multipart) to pdfapihub.com and sending an API key in the CLIENT-API-KEY header. That stays within the described conversion purpose, but it means user content (PDFs) and an API key are transmitted to an external service — a privacy/security consideration.
Install Mechanism
Instruction-only skill with no install spec or code files. Lowest-risk install posture (nothing is written to disk by the skill itself).
Credentials
The skill requires an API key (skill.json marks auth required and SKILL.md shows sending CLIENT-API-KEY), but the registry metadata lists no required env vars/credentials. This is a minor metadata mismatch: the service needs an API key but the skill manifest doesn't declare how it expects the agent to provide it (env var, config store, or runtime prompt).
Persistence & Privilege
always:false and no install actions. The skill does not request persistent or elevated privileges and does not modify other skills or system settings.
