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

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 10d ago.

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.

Origin

This is a copy

91% identical to gen — 5 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Quick Generate

Generate an image immediately from the user's description. This is the fast path — skip exploration and go straight to generation.

Instructions

  1. Look at the user's prompt: $ARGUMENTS
  2. If the prompt is very short (under 10 words), call enhance_prompt first to enrich it, then use the enhanced result
  3. If the prompt is already detailed (10+ words), use it directly
  4. Delegate to the image-generator agent with the prompt (keeps base64 data out of main context)
  5. When the agent returns, show a brief one-line creative comment about the generation

Do NOT:

  • Ask for confirmation before generating
  • Suggest alternatives or options
  • Run search_gallery for references
  • Give lengthy explanations or describe the image
  • Call generate_image directly — always delegate to image-generator agent

This is a quick-fire command. Generate and show.

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.
