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.

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 | $0.00073 | $0.00473 |
| Opus 5 | $0.00036 | $0.00236 |
| Sonnet 5 | $0.00015 | $0.00095 |
| Haiku 4.5 | $0.00007 | $0.00047 |
Grade A, and why
webshop-product-search 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 7d 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
Skill: WebShop Product Search
Core Workflow
- Interpret Criteria: Extract key product attributes from the user's instruction (e.g., product type, features, price constraints).
- Formulate Query: Construct a concise search string prioritizing the core product type and critical attributes. Start broad; refine if results are poor.
- Execute Search: Use the
search[keywords]action to submit the query. Keywords must be a single string enclosed in brackets. - Validate Results: Success is marked by a "Page 1" observation containing product listings. If 0 results are returned, re-invoke with a broader or alternative query. If all results exceed the user's price constraint, refine with additional terms.
Key Decision Logic
- Trigger Condition: This skill is the entry point for a new product discovery task. Also activate when the observation contains "[SEP] Search" or "[SEP] Back to Search".
- Output Handoff: The search results page is passed to downstream skills (e.g.,
webshop-result-filter,webshop-product-evaluator) for individual product analysis.
Constraints
- Do not use this skill if no search action is available in the current state.
- Do not include multiple actions or extra formatting in the search keywords.
Example from Trajectory
Instruction: "i need a long clip-in hair extension which is natural looking, and price lower than 40.00 dollars" Skill Execution:
- Criteria identified:
product_type="clip-in hair extension",attribute="long",attribute="natural looking",budget="<40.00". - Query formulated: Prioritizes core product type and key attribute ->
"long clip-in hair extension". - Action:
search[long clip-in hair extension]
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-product-search is a skill published in the GitHub repository zjunlp/SkillNet (1,256 stars, last pushed 2d ago), licensed MIT. It adds 73 tokens to every session and 473 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.
