Security Scan

The skill's requirements and instructions are consistent with its stated purpose (upload a PDF and password to pdfapihub.com to get an unlocked PDF), but it does involve sending user files and passwords to a third-party service — review privacy before use.

Purpose & Capability

Name, description, SKILL.md and skill.json consistently describe using PDFAPIHub's /unlockPdf endpoint to remove PDF passwords. The skill does not request unrelated binaries, environment variables, or system access.

Instruction Scope

Runtime instructions are narrowly scoped to sending a PDF (via URL, base64, or multipart) and the password to https://pdfapihub.com/api/v1/unlockPdf with a CLIENT-API-KEY header. This is coherent for the stated purpose but explicitly transmits the PDF and password to a third party — a privacy risk the SKILL.md itself warns about.

Install Mechanism

No install spec or code is included (instruction-only). Nothing is written to disk or downloaded during install by the skill package itself.

Credentials

The skill requires an API key sent in the CLIENT-API-KEY header (skill.json marks auth required). The registry metadata shows no required environment variables; this is acceptable for an instruction-only skill, but users must supply/store the API key externally (no env var is pre-declared). No unrelated credentials or secrets are requested.

Persistence & Privilege

always:false and no install/update behavior. The skill does not request persistent presence, nor does it modify other skills or system settings. disable-model-invocation is false (normal), meaning the agent may call the skill autonomously if allowed.

Assessment

This skill appears to do what it says: it uploads your encrypted PDF and the provided password to pdfapihub.com and returns an unlocked PDF. Before installing or using it: (1) confirm you trust PDFAPIHub and read their privacy/retention policy (SKILL.md claims files are auto-deleted after 30 days); (2) do NOT send highly sensitive documents or passwords reused elsewhere; (3) use a throwaway password or a copy of the document when testing; (4) store your API key securely (the skill expects a CLIENT-API-KEY header but does not declare an env var — you will need to provide the key at call time); (5) consider local alternatives for decrypting highly sensitive PDFs if you cannot trust a third party. If you need more assurance, ask the skill publisher for a company homepage, privacy policy, and security contact before use.

What It Does

Removes password protection from an encrypted PDF via the PDFAPIHub hosted API. Your PDF file and the decryption password are uploaded to PDFAPIHub servers, where the service decrypts the document and returns the unlocked PDF.

When to Use

• Decrypt a password-protected PDF for further processing
• Remove read restrictions from a PDF you own

Required Inputs

• password — the password to unlock the PDF
• Plus one of: url, base64_pdf, or multipart file upload

Authentication

This skill calls the PDFAPIHub hosted API at https://pdfapihub.com/api. Your PDF and password are sent to PDFAPIHub servers for decryption.

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

Security & Privacy:

• Your PDF file and decryption password are transmitted to PDFAPIHub's cloud service over HTTPS
• Do not send highly sensitive documents or passwords you use elsewhere without understanding this risk
• Files are auto-deleted from PDFAPIHub servers after 30 days
• PDFAPIHub does not store or log passwords after processing

Use Cases

• Legacy Document Access — Unlock old password-protected PDFs when you have the password
• Workflow Automation — Decrypt PDFs in an automated pipeline before merging, splitting, or parsing
• Print Enablement — Remove print restrictions from PDFs you own for printing
• Content Extraction — Unlock PDFs before running OCR or text extraction
• Pre-Processing — Decrypt encrypted PDFs before further PDF operations (merge, compress, watermark)
