multi-search-engine

multi-search-engine is a skill for Claude Code, Codex from beita6969/ScienceClaw. It costs 46 tokens per session (988 once invoked), scanned A, original, MIT.

A search tool that sends queries to 17 domestic and international search engines, including Google, Bing, DuckDuckGo, Baidu, and WolframAlpha. It supports search operators, time filters, and site-specific searches.

In plain words
What is it for?
Use it to run web searches, search specific sites, apply time or advanced-query filters, compare regional engines, and send knowledge questions to WolframAlpha.
Why use it?
It lets you compare results from different search services instead of relying on one search index. This can help when coverage, privacy, regional results, or a specialized answer source matters.

Token cost

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.

Security

Grade A, and why

multi-search-engine 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 4d 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.

Changes

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.
