Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00045 | $0.01316 |
| Opus 5 | $0.00023 | $0.00658 |
| Sonnet 5 | $0.00009 | $0.00263 |
| Haiku 4.5 | $0.00005 | $0.00132 |
Grade A, and why
extension-assets 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 today.
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 — 156 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Workflow (Execute This)
Step 1: Generate or locate source icon
Ask user: "Do you have a source logo? (SVG or PNG, min 512x512)"
If no source — generate SVG directly: Create a clean, professional SVG icon. Design should be:
- Simple geometric shapes (recognizable at 16x16)
- Flat design, no gradients (clean at all sizes)
- Natural, hand-crafted look (NOT AI-generated style)
- 2-3 colors max, bold contrast
Save as icon.svg in project root.
Step 2: Convert SVG → PNG (Node.js script)
npm install -D sharp
node scripts/generate-icons.js
What ships with it
5 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.
