Install

Put Jetformat on the machine, then in the host

The Skill and Harness plugin do not convert files. They start the local CLI. No MCP, no upload.

CLI

Download the ready-to-run binary, put it on PATH, and sign in so local jobs can consume credits.

CLI

jetformat --help
jetformat convert report.docx -o report.pdf

Drop SKILL.md where Codex / ChatGPT loads skills. The model is instructed to run jetformat.

CLI

mkdir -p ~/.agents/skills
cp -R plugins/openai/skills/jetformat ~/.agents/skills/jetformat

Patch Harness. Tools spawn the same CLI for Office, HTML, text, validation, and PDF workflows.

CLI

dsh web --patch plugins/deepseek-harness/cordis.patch.yml

“Convert board-deck.pptx to PDF and show the first page.” The agent should call jetformat, not unzip the file.

Install the CLI, then the GPT Skill or DeepSeek Harness plugin. The model runs jetformat. The PDF lands on disk.
