SkillNet is infrastructure for finding, creating, evaluating, combining, and coordinating reusable capabilities for AI agents. Agent developers use it as a searchable and installable library of skills and as a system for selecting skills for particular tasks. The catalogue contains skills that can be discovered, installed, or used with SkillNet.
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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00085 | $0.00467 |
| Opus 5 | $0.00043 | $0.00234 |
| Sonnet 5 | $0.00017 | $0.00093 |
| Haiku 4.5 | $0.00009 | $0.00047 |
Grade A, and why
webshop-attribute-selector 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 2d 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.
What it actually says
Instructions
When to Use
Activate this skill when ALL of the following are true:
- You are on a product detail page (not a search results page).
- The observation contains configurable product options (e.g., "flavor", "size") listed as available actions.
- The user's instruction specifies required values for one or more of these attributes (e.g., "gluten free", "4 ounce (pack of 2)", "smoked peppered bacon").
Core Process
- Parse Requirements: From the user's instruction, extract the required attribute values (e.g., target flavor, size, dietary feature).
- Map to Options: Examine the list of available actions (clickables). Identify which clickable text corresponds to each required attribute value.
- Use exact or fuzzy matching (see
scripts/match_attribute.pyfor logic). - Prioritize exact matches. For dietary features like "gluten free" or "vegetarian," the product title or description may already confirm this; your goal is to select the correct flavor/size.
- Use exact or fuzzy matching (see
- Execute Selection: For each identified attribute option, perform a
click[value]action, wherevalueis the exact text of the matching clickable. - Finalize: After all required attributes are selected, if a "Buy Now" or similar action is available and the instruction implies a purchase, you may proceed to click it.
Important Notes
- Do not use this skill on search results pages. Use search actions there.
- If a required attribute cannot be matched to any available clickable, do not click. Re-evaluate the instruction or consider a different product.
- The observation may refresh after each click, showing the same page with selected options highlighted. Continue until all specified attributes are satisfied.
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.

webshop-attribute-selector is a skill published in the GitHub repository zjunlp/SkillNet (1,253 stars, last pushed yesterday), licensed MIT. It adds 85 tokens to every session and 467 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
