Is the Doc Builder skill free?

Yes. The skill itself is free from naggarwal1/doc-builder. SkillProof publishes the install command and an independent test verdict at no cost.

What is the Doc Builder 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 Doc Builder?

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 Doc Builder 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.

Test report

Verdict: Tested · Works
Score: 9.2/10
Tested: Jul 16, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · b4a0531

Built a real Q1 investor-update doc from the skill's rules and it correctly withheld the TOC because the filled content came in under its own 400-word threshold — a concrete case of the skill applying its stated 'word count comes first' rule rather than mechanically adding a TOC whenever 3+ h2 sections exist, something the freeform baseline had no equivalent logic for.

Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

What Doc Builder does

Converts a rough draft, outline, or bullet list into a branded, responsive, single-file HTML document (pitch deck, investor update, sales proposal, one-pager, article, or generic memo) with a table of contents, collapsibles, slide nav, or paged layout as appropriate. Triggers on "interactive doc," "HTML doc," "turn this into a doc," "make this look good," "style this," or any request for a document instead of a PDF.

How to install Doc Builder

git clone https://github.com/naggarwal1/doc-builder
