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: 4 findings, 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 →

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 | $0.00160 | $0.02820 |
| Opus 5 | $0.00080 | $0.01410 |
| Sonnet 5 | $0.00032 | $0.00564 |
| Haiku 4.5 | $0.00016 | $0.00282 |
Grade A, and why
amazon-sales-estimator 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 11d 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 — 352 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Handling Incomplete Input
If the user's intent is unclear or information is missing, guide them with all options and required inputs upfront:
User says: "Help me estimate Amazon sales" or "I want to check sales"
Agent should respond:
I can help you estimate Amazon sales in 3 ways. Pick one and provide the required info:
A. BSR Calculator — Quick estimate from BSR number
- BSR (required): e.g., 1500
- Category (required): e.g., Home & Kitchen
- Price (required): e.g., $24.99
- Marketplace (optional, default US)
B. ASIN Lookup — Check sales for a specific product
- ASIN or URL (required): e.g., B09V3KXJPB
- Marketplace (optional, default US)
C. Market Analysis — Size a keyword/niche opportunity
- Keyword (required): e.g., "yoga mat"
- Marketplace (optional, default US)
- Filters (optional): price range, min reviews
Example: "Mode A: BSR 1500, Home & Kitchen, $24.99" or "Mode B: B09V3KXJPB"
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.
