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.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Excessive Agency · line 6 Skill selects an external model or provider that may use a different account or billing plan than the operator expects. Undisclosed model switches can cause unexpected cost or quota consumption.Fix: Remove the model/provider override or disclose it prominently and require explicit operator approval before invoking an external coding CLI or billed model.
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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00101 | $0.01029 |
| Opus 5 | $0.00051 | $0.00515 |
| Sonnet 5 | $0.00020 | $0.00206 |
| Haiku 4.5 | $0.00010 | $0.00103 |
Grade A, and why
image-prompt 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.

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.
Image Prompt Generator
Analyze the preceding text, article, or post and generate a detailed, platform-ready image prompt for AI text-to-image tools.
Process
- Identify the Central Idea - Distill the main concept or narrative into one sentence
- Extract Visual Elements - Find symbols, metaphors, settings, or scenarios that represent the content's essence
- Define the Mood - Match the emotional atmosphere: inspirational, urgent, contemplative, dynamic, warm, authoritative
- Construct the Prompt - Compose a 50-150 word description with subject, composition, lighting, color palette, atmosphere
Visual Element Selection for 31C Content
Match content type to visual language:
| Content Type | Visual Direction |
|---|---|
| Maritime/leadership metaphors | Sailing, navigation, open water, helm, compass, horizon |
| Product/technical | Networks, data flows, light particles, fiber optics, server rooms |
| Platform/building narrative | Architecture, bridges, foundations, construction, engineering |
| Expansion/market | Landscapes, coastlines, cities at dawn, maps, new horizons |
| Tribe/culture | Warm light, human silhouettes, collaborative spaces, depth |
| Sovereignty/independence | National landmarks, flags in wind, fortified structures, vaults |
| Speed/growth | Motion blur, launch trajectories, acceleration, time-lapse |
Default brand palette: deep blues, teals, warm amber accents.
Output Format
Deliver exactly this structure:
**Core Theme Identified:** [One sentence - the central idea of the source content]
**Image Prompt:**
[50-150 words. Specific, descriptive, platform-ready. Include: subject matter, composition,
lighting, color palette, atmosphere. Only tangible, photographable elements.]
**Parameters:**
- Aspect Ratio: 16:9
- Style: Photorealistic, high-resolution, natural lighting, authentic textures
- No text, typography, words, letters, numbers, or written elements
**Platform Suffix (Midjourney):** --ar 16:9 --v 6.1 --style raw --s 250
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.
