InDesign

Bridges Claude into Adobe InDesign by piping ExtendScript commands through a local Python tool called Flue. You send shell commands, Flue translates them into ExtendScript, runs them inside the open InDesign document, and returns structured JSON. Useful when you need an agent to inspect or edit spreads, text frames, styles, or other layout elements that only exist inside InDesign's runtime. Part of a larger Flue ecosystem that covers most Adobe apps plus Blender, Houdini, and Office using the same stdin/stdout contract. The skill documentation is clear about staying cautious since you're acting inside professional production files. Has passed security audits from Gen Agent Trust Hub, Socket, and Snyk, with 1.8K installs and decent GitHub activity.

Install

$ npx -y skills add sfkislev/flue --skill InDesign --agent claude-code

Installs into .claude/skills of the current project.

Files

This skill lets a coding agent operate Adobe InDesign on the desktop through Flue, a local shell-to-application bridge. The agent pipes ExtendScript into indesign_bridge.py and gets structured JSON back.

agent shell -> indesign_bridge.py -> ExtendScript -> JSON result

When to use

The human requests work performed inside InDesign — inspect the open document, spreads, pages, frames, text flows, styles; make bounded edits; run small ExtendScript steps. A CLI agent cannot act inside InDesign without a bridge like Flue.

How to proceed

Read FLUE.md in this directory first. It explains how Flue works, the bridge contract, a worked ExtendScript example, and safety expectations.
If Flue is installed: also read C:\Users\fredd\.claude\skills\flue\SKILL.md and adapters/indesign_adapter/APP.md for the operational contract, then work from there.
If Flue is not installed: tell the human. The install command is pip install flue && flue setup. Do not install without explicit approval in the current session.
