cli-anything-freecad

Q: How do I install cli-anything-freecad?

Run npx skills add https://github.com/hkuds/cli-anything --skill cli-anything-freecad in your project. The skills CLI detects the agents you use and copies the skill into the right folder. For Claude Code you can also place the skill folder at ~/.claude/skills/cli-anything-freecad/ (personal) or .claude/skills/cli-anything-freecad/ (project).

Install

Works with every agent the skills CLI supports.

npx skills add https://github.com/hkuds/cli-anything --skill cli-anything-freecad

01
Install
Run the command in your project. The CLI asks which agents to install for.
02
Describe the task
Ask your agent for something this skill covers. It loads cli-anything-freecad automatically when relevant.
03
Review the result
The agent follows the SKILL.md steps, scripts and references bundled with the skill.

SKILL.md

The instructions your agent reads when the skill is triggered.

cli-anything-freecad

Complete CLI harness for FreeCAD — 258 commands across 17 groups covering ALL workbenches.

Prerequisites

FreeCAD must be installed: freecadcmd must be in PATH.

Installation

pip install -e freecad/agent-harness

Basic Usage

cli-anything-freecad --json <command>           # JSON output for agents
cli-anything-freecad --json -p proj.json <cmd>  # With project file
cli-anything-freecad                            # Interactive REPL

Preview, Live Preview, and Motion

FreeCAD is currently the deepest preview integration in this branch.

Preview commands:

# List preview recipes
cli-anything-freecad --json -p proj.json preview recipes

# Capture a real 4-view bundle
cli-anything-freecad --json -p proj.json preview capture --recipe quick

# Start poll-mode live preview
cli-anything-freecad --json -p proj.json preview live start --recipe quick --mode poll --source-poll-ms 500

# Query current live state without rendering
cli-anything-freecad --json -p proj.json preview live status --recipe quick

# Stop live preview publication
cli-anything-freecad --json -p proj.json preview live stop --recipe quick

Typical quick bundle artifacts:

hero.png
front.png
top.png
right.png

Live preview persists:

session.json
immutable bundle directories
trajectory.json

preview live status --json is intended for agents and includes a compact trajectory_summary in addition to _session_dir, current bundle refs, and _trajectory_path.

Viewer commands:

cli-hub previews inspect /path/to/bundle-or-session
cli-hub previews html /path/to/bundle-or-session -o page.html
cli-hub previews watch /path/to/session --open
cli-hub previews open /path/to/bundle-or-session

Motion commands remain separate from preview and are used for final truthful frame rendering and showcase videos:

cli-anything-freecad --json -p proj.json motion new --name spin --duration 6 --fps 24
cli-anything-freecad --json -p proj.json motion keyframe spin --time 0.0 --part 0 --position 0,0,0

Missing FreeCAD: Clear install instructions
Invalid types: Lists valid options
Index out of range: Reports valid range
File exists: Use --overwrite

Agent Preview Notes

Use preview capture --json whenever geometric changes need visual verification.
Use preview live start for iterative build loops; prefer poll mode when the project file is being saved repeatedly.
Use preview live status --json as the cheap status probe before reading the full trajectory.json.
Treat _bundle_dir as a single snapshot only; the stable live identity is _session_dir plus _trajectory_path.
Use cli-hub previews ... only to inspect/open already-published previews.
