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 | $0.00132 | $0.02558 |
| Opus 5.5 | $0.00053 | $0.01023 |
| Sonnet 5.5 | $0.00026 | $0.00512 |
| Haiku 4.5 | $0.00013 | $0.00256 |
Grade A, and why
zyte-ecommerce-products-compare-skill 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 — 271 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Zyte E-Commerce Products Compare Skill
Compare products from any e-commerce site by extracting structured data via the Zyte API, building a normalized comparison table, and recommending the best option.
Skill structure
zyte-ecommerce-products-compare-skill/
├── SKILL.md ← Workflow and instructions (you are here)
├── scripts/
│ ├── fetch_products.py ← Parallel fetcher (2–20+ URLs, rate-limit aware)
│ └── parse_product.py ← Response parser (handles edge cases in Zyte output)
└── references/
└── zyte-api-notes.md ← API reference notes and known gotchas
When to read what:
scripts/fetch_products.py— always. This is the primary data fetching tool.scripts/parse_product.py— always. Run it on each fetched response file.references/zyte-api-notes.md— when you hit unexpected errors or need to understand a parsing edge case.
Prerequisites
python3(3.8+, stdlib only — no pip installs required)ZYTE_API_KEYset in the environment
Input
Gather from the user:
| Field | Required | Description |
|---|---|---|
urls |
Yes | List of product page URLs (at least 1, ideally 2+) |
intent |
No | What the user cares about (e.g. "best value", "most durable") |
api_key |
Yes | Zyte API key (prefer $ZYTE_API_KEY from env) |
Workflow
Step 1 — Validate inputs
- Confirm at least one URL is provided. If only one URL is given, extract and present its data but note that comparison requires 2+.
- Each URL must start with
http://orhttps://. - Verify
ZYTE_API_KEYis set:
If empty, ask the user to export it.echo "$ZYTE_API_KEY" | head -c 4; echo "..." - If URLs span very different product categories (e.g. footwear and electronics), warn the user and ask for confirmation before proceeding.
What ships with it
6 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.
