Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

happy-image-gen scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

The scan reads SKILL.md. This mod also ships 12 executable files (scripts/main.ts, scripts/providers/ark.ts, scripts/providers/bailian.ts, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 100 lines — stays where its author put it; the contents beside it link to each section on GitHub.

happy-image-gen

Generates still images across 8 providers through one CLI: bun scripts/main.ts .... The same CLI handles text-to-image and image-to-image (reference-driven) edits.

Quick usage

bun scripts/main.ts --prompt "A calico cat on green grass, cinematic light" --ar 16:9 --image ./out.png

When to invoke this skill

Invoke this skill whenever the user:

  • Asks to generate, create, draw, render, illustrate, or synthesize an image from text.
  • Asks to restyle or transform an existing image they provide a path to.
  • Names any image-generation model (DALL·E, gpt-image, Flux, SDXL, Gemini Image, Imagen, Seedream, Kolors, Wanx, Stable Diffusion) without specifying 即梦/Dreamina/Jimeng.

Route to happy-dreamina instead when the user explicitly names 即梦, Jimeng, or the dreamina CLI.

Step 0: Preflight (BLOCKING — run before any generation)

Run these checks:

  1. Locate EXTEND.md config. Check in order:

    • ./.happy-skills/happy-image-gen/EXTEND.md (project)
    • $XDG_CONFIG_HOME/happy-skills/happy-image-gen/EXTEND.md
    • ~/.happy-skills/happy-image-gen/EXTEND.md (user)

    If none exist, run bun scripts/main.ts --setup and follow references/config/first-time-setup.md to create one. Do not proceed to generation until the user has at least one provider configured.

  2. Verify a provider is usable. Confirm either an env var is set (e.g., OPENAI_API_KEY) or EXTEND.md references an api_key_env / api_key_source that resolves. If nothing resolves, loop back to setup.

  3. Verify Bun is available. Run command -v bun. If missing, fall back to npx -y bun scripts/main.ts ....

Step 1: Choose a provider

Pick in this order of preference:

  1. --provider <id> explicitly passed by the user.
  2. The default_provider in EXTEND.md.
  3. The first provider whose API key is present in the environment. Priority when auto-detecting: openai → google → replicate → stability → fal → ark → bailian → siliconflow.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
