Is the Keras3 (R) skill free?

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

What is the Keras3 (R) 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 Keras3 (R)?

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 Keras3 (R) 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)

Baseline R code used the keras2-era `layer_input()` (not exported by keras3, would error at runtime) and `%>%`/c()-based tensor merging; the skill's own patterns correctly use `keras_input()`, `layer_add(list(...))`, and named callback constructors — a real, verifiable correctness fix, not just style.

What Keras3 (R) does

Reference skill for building deep learning models with the keras3 R package. Covers the three model-building APIs, the audio/image/text preprocessing layer ecosystem, 30+ pretrained applications, multi-backend (TensorFlow/JAX/PyTorch) switching, and correct R-idiomatic function names. Triggers on keras3-specific terms like 'Functional API', 'layer_*', 'JAX backend', or 'custom training loop'.

How to install Keras3 (R)

git clone https://github.com/GiulSposito/r-claude-skills.git
mkdir -p ~/.claude/skills
cp -r r-claude-skills/.claude/skills/keras3 ~/.claude/skills/keras3

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

Commands — how to trigger Keras3 (R)
