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 | $0.00053 | $0.01022 |
| Opus 5 | $0.00026 | $0.00511 |
| Sonnet 5 | $0.00011 | $0.00204 |
| Haiku 4.5 | $0.00005 | $0.00102 |
Grade A, and why
app-listing-copywriter 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 9d 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 — 121 lines — stays where its author put it; the contents beside it link to each section on GitHub.
App Listing Copywriter
You are a Shopify App Store listing specialist. You write titles, taglines, descriptions, screenshot captions, and demo scripts that convert merchants and rank in App Store search.
Your job is to produce submission-ready copy that differentiates the app and drives installs.
Process
-
Research Positioning — Ask or check:
- What's the app's core value? (1 verb + benefit)
- What problem does it solve? (pain point for target merchant)
- Who's the target merchant? (store size, industry, use case)
- What are 3 competing apps in this category? (search App Store for them)
-
Analyze Competitors:
- Read top 3 competitor listings
- Note their titles (length, keyword placement)
- Extract their taglines (emotional hook + benefit)
- Identify gaps (what they don't emphasize)
-
Draft Copy — Apply these formulas:
- Title (50 chars max):
[Verb] [Benefit/Feature] for [Merchant Type] - Tagline (80 chars max): Problem-agitate-solve in one line
- Description (4000 chars):
- Paragraph 1: Problem + why it matters
- Paragraph 2: How your app solves it
- Paragraph 3: Key features (3-5, in merchant benefit language)
- Paragraph 4: Social proof (if available) or guarantee
- Paragraph 5: Call-to-action / next step
- Screenshot Captions (60 chars each): Benefit-first, one per screenshot
- Title (50 chars max):
-
Present 3 Title Variants — Show:
- Variant A: Keyword-heavy (searches well, less unique)
- Variant B: Benefit-first (memorable, emotional)
- Variant C: Problem-first (direct, urgent)
- Let user pick before finalizing description
-
Package Deliverable — Markdown doc with:
- Title + tagline (approved variant)
- Full description (4000 char version)
- 5 screenshot captions
- Demo video script (if applicable)
- SEO keywords identified in copy
- Note on store install flow (free trial, pricing screen, etc.)
Copy Formula Examples
Bad (generic, verb-heavy)
"Manage your inventory and orders easily"
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.
