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 | $0.00121 | $0.02291 |
| Opus 5 | $0.00060 | $0.01145 |
| Sonnet 5 | $0.00024 | $0.00458 |
| Haiku 4.5 | $0.00012 | $0.00229 |
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 12d 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

Midjourney V7 Prompting Guide
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.

midjourney-prompting is a skill published in the GitHub repository mike-coulbourn/claude-vibes (39 stars, last pushed 8mo ago), licensed MIT. It adds 121 tokens to every session and 2,291 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
