Skill for using the command-line tool pdftk (PDFtk Server) for working with PDF files. Use when asked to merge PDFs, split PDFs, rotate pages, encrypt or dec...
Usage Guidance
This skill is a helpful reference for using the pdftk CLI and appears internally consistent. Before using: (1) Install pdftk from your OS package manager or the vendor site and verify the binary (do not download from untrusted URLs). (2) Avoid putting PDF passwords on the command line — prefer protected inputs or interactive prompts to prevent leakage via process lists/shell history. (3) Be mindful that pdftk operates on local files: ensure you only process files you have permission to handle and that you protect sensitive PDFs. (4) If you plan to redistribute pdftk binaries, review the licensing notes included in the references.
Capability Analysis
Type: OpenClaw Skill
Name: pdftk-server
Version: 1.0.1
The OpenClaw AgentSkills bundle for 'pdftk-server' is benign. All files, including SKILL.md and reference documentation, consistently describe the installation and usage of the legitimate command-line tool PDFtk for PDF manipulation. The installation instructions in SKILL.md and references/download.md use standard package managers (winget, brew, apt-get, dnf) or direct downloads via `curl -LO` from official sources (e.g., `pdflabs.com`) for the tool's installer or source code. There is no evidence of data exfiltration, malicious execution, persistence mechanisms, prompt injection with harmful objectives, obfuscation, or other indicators of malicious intent. All actions are aligned with the stated purpose of enabling PDF processing.
Capability Assessment
Purpose & Capability
The name/description promise PDF manipulation via PDFtk Server and the SKILL.md contains only pdftk usage, examples, and platform package-manager install suggestions — all directly relevant. No unrelated binaries, env vars, or network endpoints are requested.
Instruction Scope
Instructions are narrowly scoped to running pdftk on local files (merge, split, encrypt, stamp, etc.). A security note: many examples show passwords provided on the command line (owner_pw, user_pw, input_pw), which can be exposed via process lists or shell history; users should avoid embedding secrets in command-line arguments when handling sensitive PDFs.
Install Mechanism
No install spec is embedded in the skill (instruction-only). The included references recommend platform package managers (winget, brew, apt, dnf) and a source archive; these are standard. Verify you install pdftk from official distro/package sources or the vendor site if you need the binary.
Credentials
The skill requests no environment variables, secrets, or config paths. The only sensitive items referenced are passwords shown as pdftk command arguments in examples — these are user-supplied at runtime and not declared env requirements.
Persistence & Privilege
always is false and the skill is user-invocable; it does not request persistent or elevated platform privileges and does not modify other skills or system-wide agent settings.
How to Use
