Usage Guidance
This skill forwards whatever images you provide to pdfapihub.com. Before using it, verify you trust that service: read its privacy policy and retention terms, avoid uploading sensitive documents (medical, ID, financial) unless you're comfortable with third-party storage/processing, and use a dedicated or limited-scope API key if possible. Because the skill is instruction-only, it won't install code on your system, but it will transmit your data over the network — confirm the HTTPS endpoints and test with non-sensitive images first.
Capability Analysis
Type: OpenClaw Skill
Name: img-to-pdf
Version: 1.0.0
The skill is a standard API wrapper for a third-party service (pdfapihub.com) that converts images to PDF documents. The implementation in skill.json and SKILL.md is consistent with its stated purpose, using standard API key authentication and providing clear parameters for image processing without any signs of malicious intent, data exfiltration, or prompt injection.
Capability Tags
Capability Assessment
Purpose & Capability
Name/description (combine images to PDF) align with the contents of SKILL.md and skill.json. The skill requires an API key sent in the CLIENT-API-KEY header and accepts image URLs, base64 images, or multipart files — all coherent with a hosted PDF conversion service.
Instruction Scope
Instructions explicitly tell the agent to POST image data (URLs, base64, or files) to https://pdfapihub.com/api/v1/convert/image/pdf. This is expected for the described function, but it means user data (images) will be transmitted to a third party; the SKILL.md does not attempt to access unrelated system files or environment variables.
Install Mechanism
No install spec and no code files — the skill is instruction-only and does not write code or binaries to disk. This minimizes install-time risk.
Credentials
The skill does not declare required environment variables but requires an API key header at runtime (skill.json declares apiKey auth). This is proportionate to the purpose; users must supply a service API key. There are no unrelated credential requests.
Persistence & Privilege
always is false and the skill does not request persistent system privileges or modify other skill/system configs. Autonomous invocation is allowed (platform default) but is not combined with elevated privileges here.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install img-to-pdf - After installation, invoke the skill by name or use
/img-to-pdf - Provide required inputs per the skill's parameter spec and get structured output
