CLI-Anything Reference
Auto-generates production-ready, agent-controllable CLI interfaces for any GUI application with accessible source code. A 7-phase pipeline maps GUI actions to backend APIs and emits Click-based harnesses with --json output mode, interactive REPL, and pytest test suites.

Installing a Generated CLI
cd <software>/agent-harness
pip install -e .
# Verify PATH entry created
which cli-anything-gimp
cli-anything-gimp --help
Using Generated CLIs
All generated CLIs share a consistent interface pattern.
GIMP Example
# Help
cli-anything-gimp --help
# Create project
cli-anything-gimp project new --width 1920 --height 1080 -o poster.json
# Machine-readable JSON output (for agent consumption)
cli-anything-gimp --json layer add -n "Background" --type solid --color "#1a1a2e"
# Interactive REPL
cli-anything-gimp
# Stateful workflow with --project flag
cli-anything-gimp --project poster.json layer add -n "Logo" --type group
cli-anything-gimp --project poster.json export render output.png --format png
LibreOffice Example
# New document
cli-anything-libreoffice document new -o report.json --type writer
# Populate document
cli-anything-libreoffice --project report.json writer add-heading -t "Q1 Report" --level 1
cli-anything-libreoffice --project report.json writer add-table --rows 4 --cols 3
# Export
cli-anything-libreoffice --project report.json export render output.pdf -p pdf --overwrite
# JSON output
cli-anything-libreoffice --json document info --project report.json
Blender Example
cli-anything-blender scene new -o scene.json
cli-anything-blender --project scene.json object add --type mesh --mesh-type CUBE
cli-anything-blender --project scene.json render image output.png --engine CYCLES
cli-anything-blender --json scene info --project scene.json
Inkscape Example
cli-anything-inkscape document new --width 800 --height 600 -o design.json
cli-anything-inkscape --project design.json shape add rect --x 10 --y 10 --w 200 --h 100
cli-anything-inkscape --project design.json export render output.svg
cli-anything-inkscape --json document info --project design.json
Output Modes
Every command supports two output modes:
| Mode | Usage | Audience |
| ------------------------ | ---------------------------------------- | ------------------ |
| Human-readable (default) | cli-anything-gimp layer add ... | Terminal / humans |
| Machine-readable JSON | cli-anything-gimp --json layer add ... | AI agents, scripts |
The --json flag is always the first argument, before any subcommands.
Interactive REPL
Enter by running the CLI with no subcommands:
cli-anything-gimp
cli-anything-blender
cli-anything-libreoffice
REPL features:
- 50-level undo/redo stack
- Persistent command history
- ANSI 256-color output (software-specific accent colors)
- Table rendering, progress indicators
- All subcommands available interactively
Running Tests
# Standard pytest run
cd <software>/agent-harness
python3 -m pytest cli_anything/<software>/tests/ -v
# Validate the installed binary is invoked (not just the module)
CLI_ANYTHING_FORCE_INSTALLED=1 python3 -m pytest cli_anything/<software>/tests/ -v -s
# Coverage
python3 -m pytest cli_anything/<software>/tests/ --cov=cli_anything/<software>
# Per-software examples
cd gimp/agent-harness && python3 -m pytest cli_anything/gimp/tests/ -v
cd blender/agent-harness && python3 -m pytest cli_anything/blender/tests/ -v
cd libreoffice/agent-harness && python3 -m pytest cli_anything/libreoffice/tests/ -v
Environment Variables
| Variable | Purpose |
| -------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------ |
| CLI_ANYTHING_FORCE_INSTALLED=1 | Forces tests to use the real installed binary (validates which cli-anything-<software> resolves correctly, not just module import) |

The 7-Phase Pipeline (HARNESS.md)
What /cli-anything triggers under the hood:
| Phase | Name | What happens |
| ----- | ----------------------- | ---------------------------------------------------------------------------------------------------- |
| 1 | Source Acquisition | Accept local path or GitHub URL; clone if needed |
| 2 | Codebase Analysis | Map GUI actions → backend APIs; inventory existing CLI tools; document data model |
| 3 | CLI Architecture Design | Choose interaction model (stateful REPL + subcommand); define command groups; plan --json output |
| 4 | Implementation | Build Click-based CLI with cli_anything.<software> namespace; implement REPL via shared ReplSkin |
| 5 | Test Planning | Write TEST.md with planned test inventory before code |
| 6 | Test Implementation | Unit tests (synthetic data) + E2E tests (real software output) + subprocess tests |
| 7 | PyPI Publishing | setup.py with find_namespace_packages(); console_scripts entry points |
Fundamental Rule: The CLI MUST delegate rendering to the real software — never reimplement functionality in Python. The target software is a hard dependency.
Generated Harness Structure
Each generated CLI follows this layout (PEP 420 namespace packages):
<software>/agent-harness/
├── setup.py # find_namespace_packages(), entry_points
├── <SOFTWARE>.md # Software-specific SOP
└── cli_anything/ # NO __init__.py (namespace package)
└── <software>/
├── __init__.py
├── __main__.py
├── <software>_cli.py # Main Click entry point
├── core/ # Domain modules (project, session, export, ...)
├── utils/
│ └── repl_skin.py # Shared REPL UI (copied from plugin)
└── tests/
├── TEST.md # Test inventory (written in phase 5)
├── test_core.py # Unit tests
└── test_full_e2e.py # E2E + subprocess tests
Why namespace packages: cli_anything/ has no __init__.py, enabling multiple separately-installed CLIs to coexist under the same cli_anything.* namespace without conflict.
Output Verification Standards
Tests verify real output using magic bytes and content analysis:
| Output Type | Verification |
| -------------------- | ----------------------------------- |
| PDF | %PDF- magic bytes + non-zero size |
| OOXML (.docx, .xlsx) | ZIP structure validation |
| CSV | Data row count + column check |
| Images | Pillow pixel value analysis |
| Audio | RMS level check (non-silent) |
