Is the Doc Writing skill free?

Yes. The skill itself is free from huangjia2019/claude-code-engineering. SkillProof publishes the install command and an independent test verdict at no cost.

What is the Doc Writing 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 Writing?

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 Writing 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 13, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · 90f7af3

Fed it a 3-route manifest across 2 source files: it correctly split output into products-api.md and categories-api.md following the bundled endpoint-doc.md template (with a real 🔒 auth marker and parameter/response tables) plus a machine-readable files_generated manifest for the next pipeline stage — a baseline pass produced one flat, ungrouped file with no manifest.

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

What Doc Writing does

Generates grouped Markdown API documentation from a JSON route manifest (method/path/file/line/middleware/type), filling in a fixed endpoint-doc.md template with parameter and response tables and an auth lock icon. Built as stage 2 of a 3-stage teaching pipeline (route-scanner to doc-writer to quality-checker) from a Claude Code course repo, so it triggers specifically once a route manifest already exists rather than for open-ended 'write my docs' requests.
