Is the Framework Builder skill free?

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

What is the Framework Builder SkillProof Score?

9.6/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 9/10, docs & honesty 5/5.

How do I install Framework 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 Framework 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.

A/B'd a 'systematize my customer onboarding' request: the unguided baseline was a 6-bullet checklist with tips like 'be friendly'; the skill run produced named, falsifiable mechanisms (e.g. a champion who onboards a second teammate is quantified as 4x more likely to expand seats, with the reasoning why) plus explicit failure signals — the exact gap the skill claims to close.

What Framework Builder does

Converts a person's ad-hoc recurring process (onboarding, triage, competitive analysis, etc.) into a structured markdown framework with five mandatory layers: evidence-backed principles, a reasoning-based methodology, named force multipliers, positive/negative success metrics, and edge-case implementation guidance. Triggers on 'systematize this', 'build a framework for X', or 'I keep doing the same thing'; gates itself with four threshold questions before proceeding so one-off tasks don't get the heavyweight treatment.

How to install Framework Builder

git clone https://github.com/framework-creator/framework-builder.git
mkdir -p ~/.claude/skills
cp -r framework-builder ~/.claude/skills/framework-builder

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