Is the Happy Image Gen skill free?

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

What is the Happy Image Gen SkillProof Score?

8.0/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 5/10, docs & honesty 5/5.

How do I install Happy Image Gen?

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 Happy Image Gen 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: Works with setup
Score: 8.0/10
Tested: Jul 31, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · 0d76de7

Cloned the repo and ran the CLI with Bun 1.x locally. `--help` printed full usage; a no-key run emitted the exact 'config: No provider selected...' error documented in SKILL.md Step 4; a run with a fake OPENAI_API_KEY reached the real OpenAI API and returned the documented '[openai] OpenAI images API 401' error, confirming the code path is live. I could not produce an actual image (no valid provider API key), so OUTPUT vs baseline is unmeasured. Source scanned clean: all base64 is image encode/decode, keys read only from standard env vars and sent only to each provider's own endpoint; paths resolve via import.meta.url with no hardcoded machine paths.

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

Installs cleanly 5/5
Triggers reliably 5/5
Output vs. baseline 5/10
Docs & honesty 5/5

What Happy Image Gen does

A text-to-image and image-to-image generation skill that wraps eight providers (OpenAI gpt-image/DALL-E, Google Gemini/Imagen, Replicate Flux/SDXL, Stability, FAL, Ark Seedream, Bailian qwen/wanx, SiliconFlow) behind a single Bun CLI, selecting a provider from an EXTEND.md config or available API keys. It triggers when the user asks to generate, draw, illustrate, render, or synthesize an image from a text prompt or reference image, including model-family names like Flux, SDXL, or Imagen. It defers to happy-dreamina when the user explicitly names Dreamina, 即梦, or Jimeng.

How to install Happy Image Gen

git clone --depth 1 https://github.com/iamzhihuix/happy-claude-skills.git /tmp/happy-image-gen-src
mkdir -p ~/.claude/skills
cp -R /tmp/happy-image-gen-src/skills/happy-image-gen ~/.claude/skills/happy-image-gen
# Requires Bun (https://bun.sh) — CLI runs as: bun scripts/main.ts ...
# Requires at least ONE provider API key in env, e.g. export OPENAI_API_KEY=sk-...
#   (or GOOGLE_API_KEY/GEMINI_API_KEY, REPLICATE_API_TOKEN, STABILITY_API_KEY, FAL_KEY,
#    ARK_API_KEY, DASHSCOPE_API_KEY, SILICONFLOW_API_KEY)
# Optional: run `bun scripts/main.ts --setup` to create an EXTEND.md default-provider config

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