The skill

The flue skill lets a coding agent drive desktop software such as Blender, Photoshop, Premiere and Unity from the shell through a small bridge that returns JSON, for people who want app control without MCP servers.

Only when you ask.

The habit

Desktop app edits, one step.

↻ Runs by itselfyou request an edit

How the habit works.
You don't have to.

Three questionsWhen does it start? How does it check its work? What does it remember?

01

It starts by itself

you request an edit. Runs in Claude Code.

  • ↻ you request an edit
  • manual request naming the app and the change

02

It checks its work

JSON success + you confirm. If a check fails, it stops.

  • ✓flue version answers before any script
  • ✓bridge script returns JSON on stdout
  • ✓JSON result reports success, not failure

03

It remembers

step log. The next run reads it first: app, last script and any quirks met.

loops/flue-desktop-step-loop/steps.md

One run, step by step.
Then it stops.

Stop ruleStops after one small script per run and at most one retry.

  1. 01

    Check Flue

    Run flue version, and if it is missing stop and tell the human that Flue is not installed.

  2. 02

    Read the adapter

    Open adapters/<app>/APP.md and search adapters/<app>/docs/api-index.txt with rg for the symbols you need.

  3. 03

    Inspect live state

    Use python3 -m flue.cli context <app> to see what the running app holds now.

  4. 04

    Run one script

    Send a small, bounded script through python3 -m flue.cli run <app> --stdin.

  5. 05

    Read the JSON

    Check that the result on stdout reports success and matches the change you asked for.

  6. 06

    Ask before saving

    Ask the human before any save, close, export, render or destructive operation.

  7. 07

    Log the step

    Write the app, the script purpose and the result into the step log.

What it may do.
Nothing more.

Safe by defaultIt writes only in its own folder and asks you before anything goes out.

Is it for you?
Use it when it fits.

Quick checkRead both lists. If the left one sounds like you, the Flue skill helps.

Use it when

  • ✓ You want an agent to edit a Blender scene
  • ✓ You script Photoshop or Premiere from the shell
  • ✓ You need live app state as JSON

Skip it when

  • – The app has no Flue adapter
  • – You want large unattended batch jobs

Questions

Flue skill, answered.
