Paste into your client configuration file (e.g. ~/Library/Application Support/Claude/claude_desktop_config.json on macOS or %APPDATA%/Claude/claude_desktop_config.json on Windows).
05 // Step-by-Step Installation
Verified Process- 1
Clone yanliudesign/mono-color-skill from GitHub
- 2
Install dependencies with pip install -r requirements.txt (or uv sync)
- 3
Copy .env.example to .env and add your API keys
- 4
Run the skill server and connect your AI client via stdio or HTTP
06 // Execution Boundaries & Security Safeguards
● Context Protection
Keeps heavy parsing and raw file structures external to the LLM. Only sanitized excerpts and structured returns are injected into agent memory turns.
● Directory Allowlisting
Enforce explicit directory allowlists and permission scopes in client configuration to ensure autonomous tool calls never breach system boundaries.
● Process Isolation
Executes in an isolated local child process communicating strictly over JSON-RPC via stdio with explicit process timeouts.
07 // Frequently Asked Questions
FAQ Schema IncludedWhat is Mono Color Skill and how does it empower AI agents?
Mono Color Skill is an open-source design capability designed for AI clients and autonomous agents. One-ink editorial print image skill — warm paper, halftone photography, active negative space, and restrained typography.
How do I install and configure Mono Color Skill?
Follow the step-by-step installation: 1) Verify your runtime (Python 3.10+), 2) Add the configuration snippet into your AI client settings (e.g. claude_desktop_config.json), 3) Restart the client to initialize tool execution.
Which AI clients and developer harnesses support Mono Color Skill?
Mono Color Skill is compatible with all AI tools supporting tool-calling and the Model Context Protocol (MCP), including Claude Desktop, Cursor, Claude Code CLI, Windsurf, OpenCode, and custom agent runtimes.
What security boundaries and sandboxing safeguards does Mono Color Skill enforce?
Mono Color Skill executes locally with strict directory allowlists and permission scopes. Heavy parsing and raw file structures stay external to the LLM context window to prevent memory saturation and unauthorized access.
Is Mono Color Skill free and open source?
Yes, Mono Color Skill is published under the MIT open-source license. You can inspect the source code and contribute on GitHub at https://github.com/yanliudesign/mono-color-skill.
