PDF Merge

合并多个 PDF 文件，支持压缩和元数据编辑（本地处理，隐私安全）

Security Scan

The skill's code, instructions, and requirements are consistent with a simple local PDF-merge utility and do not request unrelated credentials or network access.

Purpose & Capability

Name/description claim merging, compression, and metadata editing. The included index.js implements exactly those operations using pdf-lib and filesystem I/O; requiring node is appropriate.

Instruction Scope

SKILL.md and the CLI only instruct running node index.js on local PDF files. The code reads/writes local files and does not perform network calls, read other config, or access environment secrets.

Install Mechanism

No registry-level install spec was provided, but SKILL.md lists npm: pdf-lib which matches the code's require('pdf-lib'). This is a minimal, typical dependency; there are no downloads from arbitrary URLs. Ensure pdf-lib is installed in your environment before running.

Credentials

The skill declares no required environment variables or credentials, and the code does not read any env vars or external credentials. The requested environment access is proportional.

Persistence & Privilege

The skill is not forced-always, does not modify other skills, and has no special persistence or privileged behavior. Autonomous invocation is allowed by platform default but the skill itself does not escalate privileges.

Assessment

This appears to be a straightforward local PDF merge tool. Before installing or running: ensure you have Node and the pdf-lib package installed in the runtime environment; confirm that your execution environment will not automatically upload files or forward logs to external services (the code itself performs only local file I/O); note the skill has no homepage/source URL and the author identity is minimal—if you require provenance, ask the publisher for the source or run the code in an isolated environment first.
