pdftk-server

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 decrypt PDFs, fill PDF forms, apply watermarks, stamp overlays, extract metadata, burst documents into pages, repair corrupted PDFs, attach or extract files, or perform any PDF manipulation from the command line.

This skill ships only metadata — no inline instructions. See the source repo for details.

Install this skill

One command (all agents)

Runs the npx skills CLI which auto-detects every AI coding agent you have installed (Claude Code, Cursor, Codex, OpenCode, Windsurf, Copilot, and 51 more).

npx skills add https://github.com/github/awesome-copilot/tree/HEAD/skills/pdftk-server

Alternative: shorthand form

npx skills add github/awesome-copilot --skill pdftk-server

Install to a specific agent

Pick the agent you use. The CLI writes the skill to that agent's standard skill directory.

npx skills add github/awesome-copilot --skill pdftk-server --agent claude-code

npx skills add github/awesome-copilot --skill pdftk-server --agent cursor

npx skills add github/awesome-copilot --skill pdftk-server --agent codex

npx skills add github/awesome-copilot --skill pdftk-server --agent opencode

npx skills add github/awesome-copilot --skill pdftk-server --agent github-copilot

npx skills add github/awesome-copilot --skill pdftk-server --agent windsurf

Manual install (no CLI)

Prefer to skip the CLI? Clone the repo and drop the skill folder into your agent's skills directory.

git clone https://github.com/github/awesome-copilot.git

cp -r awesome-copilot/skills/pdftk-server ~/.claude/skills/

For other agents, replace ~/.claude/skills/ with their skill directory — see the full list.

Use it

Once installed, ask your agent to "use the pdftk-server skill" or describe what you want (e.g. "Skill for using the command-line tool pdftk (PDFtk Server) for working with PDF"). Most agents auto-discover the skill from its SKILL.md description — no slash command needed.

Requires: Node.js 18+ for npx skills. Skill files are MIT-style permissive by default — check the source repo for the actual license.
