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 | $0.00064 | $0.02415 |
| Opus 5.5 | $0.00026 | $0.00966 |
| Sonnet 5.5 | $0.00013 | $0.00483 |
| Haiku 4.5 | $0.00006 | $0.00242 |
Grade A, and why
app-store-screenshots 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 2mo 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 — 293 lines — stays where its author put it; the contents beside it link to each section on GitHub.

The First 3 Rule
80% of App Store impressions show only the first 3 screenshots (before the user scrolls). These three must:
- Communicate the core value proposition
- Show the best feature/outcome
- Differentiate from competitors
Screenshot Gallery Order
| Position | Content | Purpose |
|---|---|---|
| 1 | Hero -- core value, best feature | Stop the scroll, communicate what the app does |
| 2 | Key differentiator | What makes you unique vs competitors |
| 3 | Most popular feature | The thing users love most |
| 4 | Social proof or outcome | Ratings, results, testimonials |
| 5-8 | Additional features | Supporting features, settings, integrations |
| 9-10 | Edge cases | Specialized features for niche users |
What ships with it
3 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.
