What is the HTML Express SkillProof Score?

9.2/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 8/10, docs & honesty 5/5.

How do I install HTML Express?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use HTML Express with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Verdict: Tested · Works
Score: 9.2/10
Tested: Jul 16, 2026
Environment: Claude Code 2.x (agent harness)

Real A/B on a 3-vendor comparison report: the skill version inlines all CSS into one file, highlights the best option per row with the design-token accent colors, and adds a 'verify before quoting' data-provenance footer per its own no-invented-metrics rule — the naive baseline HTML table has none of that.

What HTML Express does

Assembles a single-file, inline-CSS HTML report (comparison tables, checklists, timelines, metric cards) from a reusable Warm Paper component set instead of dumping information into Markdown. Triggers when a user asks for an HTML report, dashboard, comparison page, or a one-file webpage they can open locally; explicitly steps aside for landing pages, PDFs, or short answers.

How to install HTML Express

git clone https://github.com/zjp1997720/html-express.git
mkdir -p ~/.claude/skills
cp -r html-express ~/.claude/skills/html-express

Skills live in ~/.claude/skills/ (global) or .claude/skills/ (per-project). Restart Claude Code after installing.
