visual-explainer

An agent skill that turns complex terminal output into styled HTML pages you actually want to read.

Ask your agent to explain a system architecture, review a diff, or compare requirements against a plan. Instead of ASCII art and box-drawing tables, it generates a self-contained HTML page and opens it in your browser.

Why

Every coding agent defaults to ASCII art when you ask for a diagram. Box-drawing characters, monospace alignment hacks, text arrows. It works for trivial cases, but anything beyond a 3-box flowchart turns into an unreadable mess.

Tables are worse. Ask the agent to compare 15 requirements against a plan and you get a wall of pipes and dashes that wraps and breaks in the terminal. The data is there but it's painful to read.

This skill fixes that. Real typography, dark/light themes, interactive Mermaid diagrams with zoom and pan. No build step, no dependencies beyond a browser.

Install

Harness	Support	Install path / behavior
Claude Code	Marketplace plugin	Preserved marketplace shape with source at plugins/visual-explainer/
Pi	Package metadata plus installer	package.json advertises the skill and prompts; install-pi.sh installs to ~/.pi/agent/skills/visual-explainer and ~/.pi/agent/prompts/
Codex CLI	Native skill path plus optional prompts	Copy to ~/.codex/skills/visual-explainer; optional prompts go in ~/.codex/prompts/ if your Codex build supports them
OpenCode/opencode	Observed skill/command paths	Copy to ~/.config/opencode/skill/visual-explainer; optional commands go in ~/.config/opencode/command/
Cursor	Rules-based guidance	Add the supplied .mdc rule; Cursor is not treated as native Agent Skills support
OpenClaw	Lightweight AGENTS/rules guidance	Use the supplied AGENTS guidance with the canonical skill directory

Claude Code (marketplace):

/plugin marketplace add nicobailon/visual-explainer
/plugin install visual-explainer@visual-explainer-marketplace

Note: Claude Code plugins namespace commands as /visual-explainer:command-name.

Pi:

pi install git:github.com/nicobailon/visual-explainer

Or from a local checkout:

git clone --depth 1 https://github.com/nicobailon/visual-explainer.git
pi install ./visual-explainer

The package manifest advertises the canonical skill and command templates:

"pi": {
  "skills": ["./plugins/visual-explainer"],
  "prompts": ["./plugins/visual-explainer/commands"]
}

If you previously used the old curl/manual installer, remove those copied files before using pi install; otherwise Pi will report skill and prompt conflicts because the user-level copies shadow the package resources:

rm -rf ~/.pi/agent/skills/visual-explainer
rm -f ~/.pi/agent/prompts/{diff-review,fact-check,generate-slides,generate-visual-plan,generate-web-diagram,plan-review,project-recap,share-page}.md

The legacy installer still works if you prefer copied files over package management:

curl -fsSL https://raw.githubusercontent.com/nicobailon/visual-explainer/main/install-pi.sh | bash

Codex CLI:

git clone --depth 1 https://github.com/nicobailon/visual-explainer.git /tmp/visual-explainer

mkdir -p ~/.codex/skills ~/.codex/prompts
cp -R /tmp/visual-explainer/plugins/visual-explainer ~/.codex/skills/visual-explainer

# Optional, only if your Codex build supports prompt templates:
cp /tmp/visual-explainer/plugins/visual-explainer/commands/*.md ~/.codex/prompts/

rm -rf /tmp/visual-explainer

Invoke with $visual-explainer or ask Codex to use the visual-explainer skill. If prompts are installed and supported, use /prompts:diff-review, /prompts:plan-review, etc.

OpenCode/opencode:

git clone --depth 1 https://github.com/nicobailon/visual-explainer.git /tmp/visual-explainer

mkdir -p ~/.config/opencode/skill ~/.config/opencode/command
cp -R /tmp/visual-explainer/plugins/visual-explainer ~/.config/opencode/skill/visual-explainer

# Optional command templates:
cp /tmp/visual-explainer/plugins/visual-explainer/commands/*.md ~/.config/opencode/command/

rm -rf /tmp/visual-explainer

Activate it by asking OpenCode to use the visual-explainer skill. Command-template behavior depends on the installed OpenCode/opencode build.

Cursor:

Add configs/cursor/visual-explainer.mdc to your Cursor rules, or copy its contents into the project rules UI. This is rules-based guidance that points Cursor at the canonical skill; it does not claim native Agent Skills support.

OpenClaw:
