Usage Guidance
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.
Capability Analysis
Type: OpenClaw Skill
Name: unlock-pdf
Version: 1.0.1
The skill is a transparent API wrapper for the PDFAPIHub service (pdfapihub.com) designed to decrypt PDF files. It clearly documents that both the PDF content and the decryption password are transmitted to the third-party service via HTTPS. There is no evidence of malicious intent, obfuscation, or unauthorized data exfiltration beyond the stated purpose of the tool.
Capability Tags
Capability Assessment
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.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install unlock-pdf - After installation, invoke the skill by name or use
/unlock-pdf - Provide required inputs per the skill's parameter spec and get structured output
