  1. 01

    Install

    Run the command in your project. The CLI asks which agents to install for.

  2. 02

    Describe the task

    Ask your agent for something this skill covers. It loads cli-anything-gimp automatically when relevant.

  3. 03

    Review the result

    The agent follows the SKILL.md steps, scripts and references bundled with the skill.

The instructions your agent reads when the skill is triggered.

cli-anything-gimp

A stateful command-line interface for image editing, built on Pillow. Designed for AI agents and power users who need to create and manipulate images without a GUI.

Installation

This CLI is installed as part of the cli-anything-gimp package:

pip install cli-anything-gimp

Prerequisites:

  • Python 3.10+
  • gimp is recommended for native batch rendering, but layered compositions can still render through the built-in Pillow path when GIMP is unavailable or when deferred draw operations are present

Usage

Basic Commands

# Show help
cli-anything-gimp --help

# Start interactive REPL mode
cli-anything-gimp

# Create a new project
cli-anything-gimp project new -o project.json

# Run with JSON output (for agent consumption)
cli-anything-gimp --json project info -p project.json

REPL Mode

When invoked without a subcommand, the CLI enters an interactive REPL session:

cli-anything-gimp
# Enter commands interactively with tab-completion and history

Command Groups

redoRedo the last undone operation
historyShow undo history

Draw

Drawing operations (applied at render time).

CommandDescription
textDraw text on a layer (by converting it to a text layer)
rectDraw a rectangle (stored as drawing operation)

Examples

Create a New Project

Create a new gimp project file.

cli-anything-gimp project new -o myproject.json
# Or with JSON output for programmatic use
cli-anything-gimp --json project new -o myproject.json

Interactive REPL Session

Start an interactive session with undo/redo support.

cli-anything-gimp
# Enter commands interactively
# Use 'help' to see available commands
# Use 'undo' and 'redo' for history navigation

Export Project

Export the project to a final output format.

cli-anything-gimp --project myproject.json export render output.png --overwrite

Layered Composition Workflow

For overlay-heavy compositions:

cli-anything-gimp --project poster.gimp-cli.json layer set 0 offset_x -48
cli-anything-gimp --project poster.gimp-cli.json layer set 0 offset_y 24
cli-anything-gimp --project poster.gimp-cli.json draw text --layer 0 --text "Launch Night" --x 96 --y 120 --size 72 --color "#f6f1e8"
cli-anything-gimp --project poster.gimp-cli.json export render output.png --overwrite

Notes:

  • layer set now accepts negative offset_x and offset_y values in both command mode and REPL mode.
  • draw text and draw rect are render-time operations. Treat the exported image, not only the project JSON, as the thing to review.
  • For projects with deferred draw ops, expect the Pillow render path to be the stable default even if GIMP is installed.

State Management

The CLI maintains session state with:

  • Undo/Redo: Up to 50 levels of history
  • Project persistence: Save/load project state as JSON
  • Session tracking: Track modifications and changes

Output Formats

All commands support dual output modes:

  • Human-readable (default): Tables, colors, formatted text
  • Machine-readable (--json flag): Structured JSON for agent consumption
# Human output
cli-anything-gimp project info -p project.json

# JSON output for agents
cli-anything-gimp --json project info -p project.json

For AI Agents

When using this CLI programmatically:

  1. Always use --json flag for parseable output
  2. Check return codes - 0 for success, non-zero for errors
  3. Parse stderr for error messages on failure
  4. Use absolute paths for all file operations
  5. Verify outputs exist after export operations
  6. Review rendered outputs after offset, draw, blend-mode, or filter changes instead of trusting saved project state alone

google/agents-cli

This skill should be used when the user wants to "publish an agent", "publish my ADK agent", "register an agent with Gemini", "publish to Gemini" (formerly Gemini Enterprise), or needs guidance on the agents-cli publish gemini command. Also use when the user wants to "manage agents in Agent Registry", "list/update/delete registered agents", or "register an MCP server". Covers ADK vs A2A registration modes, programmatic and interactive usage, flag reference, auto-detection from deployment metadata, Agent Registry fleet management, and troubleshooting. Part of the agents-cli skills suite. Do NOT use for deployment (use google-agents-cli-deploy).

Covers eval metrics, dataset schema, LLM-as-judge scoring, and common failure causes. Applies to any agents-cli project, whatever framework the agent is written in. Do NOT use for agent API code patterns (ADK: use google-agents-cli-adk-code), deployment (use google-agents-cli-deploy), or project scaffolding (use google-agents-cli-scaffold).

codex-pet

prime-skills/runcomfy-agent-skills

Codex Pet generator on RunComfy. Build a Codex-compatible Codex Pet spritesheet.webp + pet.json from a single reference image, drop it into ${CODEXHOME:-$HOME/.codex}/pets/ / and Codex picks it up as a custom Codex Pet next to the 8 built-ins. This skill produces the exact Codex Pet atlas Codex expects (1536x1872 PNG/WebP, 8 cols x 9 rows, 192x208 cells, 9 animation states — idle, running-right, running-left, waving, jumping, failed, waiting, running, review). Calls OpenAI GPT Image 2 edit ONCE via the local RunComfy CLI as runcomfy run openai/gpt-image-2/edit to produce a canonical Codex Pet pose, then assembles all 9 animation rows programmatically with ImageMagick micro-transforms — no Codex Pro, no $imagegen, no OPENAIAPIKEY required, only RUNCOMFYTOKEN. Triggers on "codex pet", "create codex pet", "make codex pet", "hatch codex pet", "/hatch image", "desktop pet codex", "codex pets", "spritesheet.webp", or any explicit ask to build a custom pet for OpenAI Codex.
