Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00085 | $0.02956 |
| Opus 5.5 | $0.00034 | $0.01182 |
| Sonnet 5.5 | $0.00017 | $0.00591 |
| Haiku 4.5 | $0.00009 | $0.00296 |
Grade A, and why
midjourney-prompting 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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 327 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Midjourney prompting guide
Version note, last verified September 2026. The current default is V8.2, and this guide covers V7, V8.1, V8.2, and Niji 7. Midjourney ships new versions a few times a year, so if the user names a newer one, or a parameter behaves unexpectedly, check https://docs.midjourney.com with WebSearch before relying on a version-specific claim here.
Quick reference: prompt structure
A Midjourney prompt has up to four parts:
/imagine [description] [image URLs] [parameters]
Key Principle: Short, specific prompts work best. Describe what you want to see, not abstract concepts.
The 7-element framework
Build complete prompts systematically:
| Element | Question | Examples |
|---|---|---|
| Subject | Who/what is in the image? | A weathered fisherman, a cyberpunk samurai |
| Medium | What art form? | Oil painting, photograph, 3D render |
| Environment | Where is this? | Stormy harbor, neon-lit alley, misty forest |
| Lighting | How is it lit? | Golden hour, dramatic backlighting, soft diffused |
| Color | What palette? | Muted blues, warm earth tones, high contrast |
| Mood | What feeling? | Melancholic, triumphant, eerie |
| Composition | How is it framed? | Rule of thirds, centered, wide shot |
Example:
A weathered fisherman, oil painting, stormy harbor at dawn,
dramatic backlighting, muted blues and grays, melancholic,
rule of thirds composition --ar 3:2

What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
