Agent Canvas Setup

Checks and installs dependencies for the agent-canvas visual editing skills (agent-eyes, agent-canvas, canvas-edit).

Quick Check

Run this first to see what's needed:

uv run .claude/skills/agent-canvas-setup/scripts/check_setup.py check

If all checks pass → Ready to use canvas skills.

If checks fail → Ask user about installation scope.

Installation Scopes

ALWAYS ask the user which scope they prefer before installing:

| Scope | What it does | Best for |

|-------|--------------|----------|

| temporary | Browsers installed globally, Python deps cached by uv on-demand (~/.cache/uv) | Most users - minimal footprint |

| local | Creates .venv in project with playwright installed | Projects wanting isolated deps |

| global | Installs browsers globally only (Python deps via uv) | Shared workstations |

Recommended Prompt to User

Agent Canvas needs some dependencies. How would you like to install them?

1. **temporary** (recommended) - Minimal footprint. Browsers installed to system cache, 
   Python packages managed on-demand by uv. Nothing added to your project.

2. **local** - Creates a .venv in this project with playwright. Good if you want 
   all dependencies tracked with the project.

3. **global** - Same as temporary. Browsers go to system cache.

Which do you prefer? (1/2/3 or temporary/local/global)

Multi-Agent Support

Agent Canvas can install skills for multiple AI agents. Use --agents to specify which agents:

| Agent | Skills Directory | Description |

|-------|------------------|-------------|

| claude | .claude/skills/ | Claude Code / Claude Desktop (default) |

| codex | .codex/skills/ | OpenAI Codex CLI |

| copilot | .github/skills/ | GitHub Copilot |

| cursor | .cursor/skills/ | Cursor IDE |

| windsurf | .windsurf/skills/ | Windsurf IDE |

| aider | .aider/skills/ | Aider |

Examples

# Install for Claude only (default)
uv run .claude/skills/agent-canvas-setup/scripts/check_setup.py install --scope temporary

# Install for Claude and Copilot
uv run .claude/skills/agent-canvas-setup/scripts/check_setup.py install --scope temporary --agents claude,copilot

# Install for all supported agents
uv run .claude/skills/agent-canvas-setup/scripts/check_setup.py install --scope temporary --agents claude,copilot,cursor,windsurf,aider

Install Commands

SKILL_DIR=".claude/skills/agent-canvas-setup/scripts"

# Temporary (recommended) - uv handles Python deps on-demand
uv run $SKILL_DIR/check_setup.py install --scope temporary

# With multi-agent support
uv run $SKILL_DIR/check_setup.py install --scope temporary --agents claude,copilot

# Local - creates .venv in project
uv run $SKILL_DIR/check_setup.py install --scope local

# Global - browsers only (Python via uv)
uv run $SKILL_DIR/check_setup.py install --scope global

What Gets Installed

Always Required

uv - Must be pre-installed by user (provides instructions if missing)
Python 3.10+ - Must be pre-installed

Installed by Setup

Playwright Chromium (~200MB) - Browser binary for automation
Location: ~/.cache/ms-playwright/ (Mac/Linux)
This is the main "weight" of the installation

Python Packages (handled by uv)

playwright - Browser automation
axe-playwright-python - Accessibility scanning

For temporary and global scopes, these are cached in ~/.cache/uv/ and loaded on-demand when running scripts.

For local scope, these are installed to .venv/ in the project.

Error Recovery

If canvas skills fail, run check first:

uv run .claude/skills/agent-canvas-setup/scripts/check_setup.py check --json

Common issues:

Playwright Chromium: not found → Run install with any scope
uv package manager: not found → User must install uv first
Python 3.10+: need 3.10+ → User must upgrade Python

Workflow Integration

Before running any canvas skill for the first time:

Run check_setup.py check
If not ready, ask user about preferred scope
Run check_setup.py install --scope <choice>
Verify with check_setup.py check again
Proceed to canvas skill

Ios Simulator Browser

by openai

vendor

Mirror an iOS Simulator into the Codex in-app browser and render SwiftUI previews from importable Swift packages in that simulator with hot reload. Use when a user wants to watch or interact with an iOS app in the browser, see a SwiftUI preview outside Xcode Canvas, iterate live on a preview, or capture browser-visible simulator proof.

Doc Screenshots

by WordPress

Annotate UI screenshots with documentation callouts in Fellyph's established visual style — uniform-width orange arrows with white halos, double-stroke target outlines, numbered callout cards, dim overlays and a framed canvas. Use this whenever the user asks to annotate a screenshot, add arrows or callouts to a screenshot, create documentation images, highlight UI controls in a capture, or produce docs/tutorial visuals for Playground, Studio or any web UI — even if they just say "add arrows to this" or "make a docs screenshot".

Goose Graphics Create Style

by gooseworks-ai

> End-to-end skill that turns a single reference image into a published Gooseworks style — analyzes the image, drafts the slim style spec, renders a hero example plus 2-3 additional formats via Playwright, writes the `gooseworks-style.json` manifest, and publishes via `npx gooseworks styles publish` so other agents can discover it. Mirrors goose-graphics-create-format but for styles.

How to use it

Copy the folder

Take majiayu000/agent-canvas-setup from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.
