PDF Editor — PDF Document Processing CLI Tool
Platform Detection (Agent must execute automatically)
Before running any CLI command, the Agent must automatically detect the platform (read env.platform: win32→Windows, darwin→Mac; or run uname -s). Do NOT ask the user about their platform.
| Variable | [Windows] | [Mac] |
|---|
<CLI> | {skill_root}/scripts/win/compdf_cli.exe | {skill_root}/scripts/mac/compdf_cli |
<LICENSE_PATH> | {skill_root}/scripts/win/license_key_windows.xml | {skill_root}/scripts/mac/license_key_mac.xml |
<LICENSE_API_BODY> | {"email":"<email>"} | {"email":"<email>"} |
<ICC_SRGB> | {skill_root}/scripts/win/PDFA/sRGB2014.icc | {skill_root}/scripts/mac/PDFA/sRGB2014.icc |
<ICC_FOGRA> | {skill_root}/scripts/win/PDFA/CoatedFOGRA39.icc | {skill_root}/scripts/mac/PDFA/CoatedFOGRA39.icc |
| Shell syntax | cmd + REM | bash + # |
{skill_root} = the absolute path of the directory containing this SKILL.md.
CLI Download & Installation (Required on first use)
The CLI binary is not included in the Skill package. It is downloaded from the official ComPDFKit distribution server (download.compdf.com) operated by PDF Technologies, Inc. The Agent must complete the following steps before the first execution:
- Check whether
<CLI> exists → skip if it does
- Inform the user that the CLI binary will be downloaded from
download.compdf.com (official ComPDFKit CDN)
- Download the appropriate archive for the platform:
- [Windows]:
https://download.compdf.com/skills/winCLI/win.zip
- [Mac]:
https://download.compdf.com/skills/macCLI/mac.zip
- Extract the archive to the
{skill_root}/scripts/ directory (the zip already contains a win/ or mac/ prefix, so the correct directory structure is formed automatically after extraction)
- [Mac] After extraction, run:
chmod +x {skill_root}/scripts/mac/compdf_cli
- Verify: run
<CLI> --help to confirm the binary is executable
Download is performed once on first use only; no re-download is needed on subsequent runs.
License Activation (Required on first use)
- Check whether
<LICENSE_PATH> exists → skip if it does
- Ask the user for their email address (explain: the email is sent to the official ComPDFKit license server to obtain a free trial license; no other data is transmitted)
- After the user confirms, send
POST https://wms.compdf.com/api/license/skillsTrial, Body: <LICENSE_API_BODY>
code=200: write the data.license XML to <LICENSE_PATH>code=500: prompt the user to retry with a different email address
- Run
<CLI> --help to verify activation

Usage Patterns (Agent quick reference)
| User says | Command |
|---|
| "Split into single pages" | <CLI> split "input.pdf" --mode all --overwrite |
| "Merge PDFs" | <CLI> merge "a.pdf" "b.pdf" --output "merged.pdf" --overwrite |
| "Extract pages X to Y" | <CLI> extract "input.pdf" --range X-Y --output "out.pdf" --overwrite |
| "Convert to PDF/A" | <CLI> convert "input.pdf" --standard pdfa-1a --overwrite |
| "Compress PDF" | <CLI> optimize "input.pdf" --compress-images --image-quality 50 --overwrite |
| "Compare two PDFs" | <CLI> compare "old.pdf" "new.pdf" --overwrite |
| "Add text watermark" | <CLI> watermark-text "input.pdf" --text "CONFIDENTIAL" --overwrite |
| "Add image watermark" | <CLI> watermark-image "input.pdf" --image "logo.png" --overwrite |
| "Remove watermark" | <CLI> watermark-delete "input.pdf" --overwrite |
| "Rotate pages" | <CLI> rotate "input.pdf" --pages X-Y --angle 90 --overwrite |
| "Delete page X" | <CLI> delete "input.pdf" --pages X --overwrite |
| "Insert pages" | <CLI> insert "target.pdf" --source "src.pdf" --pages X --at N --overwrite |
| "Insert image" | <CLI> insert "target.pdf" --image "img.png" --at N --width 595 --height 842 --overwrite |
⚠️ Mac watermark commands require --full-screen to be passed explicitly (when tiling is desired).
Limitations
- Page ranges only support
"N" or "N-M"; comma-separated values are not supported
- Except for
merge (which skips encrypted files automatically), encrypted PDFs will cause an error and exit
- Wildcards, output path equal to input path, and multi-threaded parallel execution are not supported
- Results of standard format conversion and optimization depend on the content of the input PDF
watermark-delete removes all watermarks; selective removal is not supportedcompare performs visual overlay comparison and does not output a structured diff list
Troubleshooting
Security & Privacy
All PDF processing is performed locally. No file content is uploaded.
| External Endpoint | Purpose | Data Sent | When | User Consent |
