Security Scan

The skill's declared behavior, instructions, and required API usage are internally consistent: it is an instruction-only wrapper that sends HTML or a URL to a third‑party PDF generation API and does not request unrelated credentials or install anything.

Purpose & Capability

Name/description match the actual behavior: SKILL.md and skill.json both describe sending HTML or a public URL to pdfapihub.com for rendering. The required functionality (an external PDF API and an API key) is appropriate for the stated purpose.

Instruction Scope

Runtime instructions are narrowly scoped: they describe forming an HTTP POST to https://pdfapihub.com/api/v1/generatePdf with either html_content or url and an API key in the CLIENT-API-KEY header. The instructions do not ask the agent to read unrelated files, system config, or other environment variables.

Install Mechanism

No install spec or code is included (instruction-only). Nothing will be downloaded or written to disk by the skill itself, which lowers risk.

Credentials

The only auth artifact required by the skill is an API key for the external service (passed in the CLIENT-API-KEY header, and declared as apiKey in skill.json). The skill does not request unrelated secrets, environment variables, or config paths.

Persistence & Privilege

The skill is not marked always:true and does not request system-wide privileges or modify other skills. Autonomous invocation is allowed (default) but that is expected for skills of this type.

Assessment

This skill forwards your HTML or a public URL to a third‑party service (pdfapihub.com) and requires an API key. Before installing, confirm you trust that service and its privacy/retention policy (the docs mention files are deleted after 30 days). Do not send sensitive secrets or personal data in HTML_content or dynamic_params unless you accept third‑party processing. Also check pricing, page limits, and whether you prefer a local renderer (headless Chromium) if you need to keep data on‑prem.

Generate PDF

What It Does

Generates a PDF document from either raw HTML content or a public URL using a headless Chromium browser. The API renders the page and returns the result as a downloadable URL, base64 string, or raw PDF file.

When to Use

• Convert an HTML template (invoice, report, certificate) into a PDF
• Take a PDF snapshot of a live webpage
• Generate PDFs with dynamic data via placeholder substitution
• Create PDFs with custom fonts, margins, and page sizes

Required Inputs

You must provide one of:

• html_content — raw HTML string to render
• url — a public URL to convert

Authentication

Send your API key in the CLIENT-API-KEY header.
