Is the Flowi skill free?

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

What is the Flowi SkillProof Score?

9.2/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 9/10, docs & honesty 4/5.

How do I install Flowi?

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 Flowi 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 · f64bc5b

Ran the bundled server for real on a written auth-flow JSON: it rendered a correctly color-coded, draggable SVG flowchart (green start pill, amber decision diamond, purple IO parallelogram) matching the schema exactly — a real, working visual planning tool, not vaporware.

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

What Flowi does

Flowi has Claude write structured JSON diagram files to a .flowi/ directory instead of drawing ASCII art. A tiny bundled Node server renders them as interactive, color-coded, drag-and-editable flowcharts at localhost:3333 with live-reload, and Claude can read back the user's visual edits. Triggers on architecture planning, user-flow mapping, state machines, and UI mockup requests.

How to install Flowi

git clone https://github.com/aiaiohhh/claude-skills-library
mkdir -p ~/.claude/skills
cp -r claude-skills-library/skills/flowi ~/.claude/skills/flowi

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

Commands — how to trigger Flowi

/flowi Writes JSON flowcharts Claude and the user can co-edit live in a local browser viewer.

It also activates on plain-language prompts like these:

Diagram this login flow so I can drag and edit it in the browser
Map out our auth state machine as an interactive flowchart
Sketch the user journey from signup to dashboard as a live diagram
