Write Mermaid diagrams that render on GitLab, GitHub, Linear and in IDE previews — whether a diagram is worth drawing at all, which type to pick, the syntax that survives both renderers, the size budget, and a render-and-look validation loop through a `diagrams:mermaid-validate` subagent. Use when a plan, MR description, review comment, ticket or doc would be clearer with a picture, or when an existing mermaid block has to be repaired.

Works with any agent that supports SKILL.md skills.

What this skill can do

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'mermaid' ] || [ -L ~/.agents/skills/'mermaid' ]; then echo 'A skill folder named mermaid already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/fprochazka/claude-code-plugins' "$d" && git -C "$d" checkout --quiet 'f8750c74a054b9b10b10838dc052cf0d898671b4' -- 'plugins/diagrams/skills/mermaid' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/diagrams/skills/mermaid' ~/.agents/skills/'mermaid' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'mermaid' ~/.claude/skills/'mermaid' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
