Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.

Draw Mermaid diagrams for the user in the thread (flowcharts, sequence, class, state, ER, Gantt, pie, mind maps, timelines, git graphs and more), with pan and zoom, the source, and SVG/PNG export. Use when the user asks for a diagram, a chart of a flow, a schema, an architecture or sequence drawing, a plan on a timeline, or when a picture of how things connect explains better than text.

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=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/gvergnaud/bise' "$d" && git -C "$d" checkout --quiet 'eec6ca08f9451afa7b87a2b105fe9ceab60d0cb7' -- 'plugins/mermaid/skills/mermaid' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/mermaid/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.
