Multi Search Engine 2.1.3

Multi search engine integration with 16 engines (7 CN + 9 Global). Supports advanced search operators, time filters, site search, privacy engines, and Wolfra...

Security Scan

The skill's requirements and runtime instructions are internally consistent with a multi‑engine search aggregator: it requests no credentials, has no install, and describes only web fetches to listed search engines.

Purpose & Capability

Name/description (multi search engine aggregator) align with the actual artifacts: config.json lists 16 search engines and SKILL.md shows URL patterns and examples. No unrelated binaries or credentials are requested.

Instruction Scope

Instructions stay within search aggregation: they call web_fetch against the declared search URLs, perform in‑memory cookie handling on 403/429, and aggregate results. One minor gap: the doc states 'Respect robots.txt' and 'rate limiting' but does not show explicit steps to fetch/parse robots.txt or enforce rate limits — this is a behavioral promise rather than an implemented spec in the instructions.

Install Mechanism

Instruction-only skill with no install spec and no code to execute locally. This minimizes disk persistence and installation risk.

Credentials

No environment variables, API keys, or config paths are required. The cookie workflow is limited to session cookies for search engine domains and is claimed to be memory-only; that is proportionate to the stated purpose.

Persistence & Privilege

Skill is not always-enabled and makes no requests to modify other skills or system config. It does not request persistent privileges.

Assessment

This skill appears coherent and low-risk from a configuration perspective: it needs no credentials and only issues web requests to the listed search engines. Before installing, consider: (1) legal/ToS: automated queries to search engines can violate their terms — ensure you have the right to run automated searches and abide by robots.txt; (2) rate limiting: confirm the platform's web_fetch enforces the claimed delays and batching to avoid being blocked; (3) cookie handling: verify the implementation truly keeps cookies only in memory and never persists them; (4) sensitive queries: the skill supports advanced operators (site:, filetype:, intext:) which can be used to locate exposed sensitive data — ensure your usage is ethical and lawful; (5) audit outputs: aggregated results may include PII or confidential links, so treat outputs appropriately. If you need stronger assurance, request the concrete runtime implementation (the code that performs web_fetch, robots.txt checks, cookie lifecycle) and review it to validate the claimed behaviors.

Multi Search Engine

Integration of 16 search engines for web crawling without API keys.

Workflow

1. Preparation: AI Agent initializes an empty in-memory cookie store. Cookies are only acquired dynamically during search operations when access is denied

2. Language Evaluation: Detect the language attribute of the search query. If the query is in Chinese, use Domestic search engines (Baidu, Bing CN, Bing INT, 360, Sogou, WeChat, Shenma). If the query is non-Chinese, use International search engines (Google, Google HK, DuckDuckGo, Yahoo, Startpage, Brave, Ecosia, Qwant, WolframAlpha). Select engines based on query relevance and availability.

3. Controlled Search: Use web_fetch to execute search requests with rate limiting:

   • Add 1-2 second delay between requests to respect server load
   • Batch requests in groups of 3-4 engines with sequential execution between batches
   • Include standard browser headers to identify as legitimate user agent
   • If access is denied (403/429), fetch engine homepage to obtain fresh session cookies

4. Cookie Management:

   • Cookies are stored ONLY in memory during runtime
   • Cookies are acquired on-demand when search requests fail
   • No cookies are read from or written to config.json or any file
   • Cookies are cleared after search session completes
   • Only session cookies from search engine domains are captured

5. Retry Mechanism: If a search fails due to cookie/session issues, retry once with freshly acquired cookies after a 2-second delay

6. Result Aggregation: Consolidate successful results from search engines, organize and summarize them to output a core search report

Security & Privacy Notice

Cookie Handling

• Purpose: Cookies are used ONLY to maintain search session state when access is denied (403/429 errors)
• Storage: Cookies are kept STRICTLY in memory during runtime - NEVER persisted to disk or config files
• Acquisition: Cookies are acquired on-demand from search engine homepages only when search requests fail
• Scope: Only session cookies from the specific search engine domain are captured
• Lifecycle: Cookies are cleared immediately after the search session completes
• No Pre-configuration: No cookies are loaded from config.json or any external file at startup
• No API Keys: This tool uses standard web search URLs, no authentication required

Crawling Ethics

• Rate Limiting: Implement reasonable delays between requests (recommend 1-2 seconds)
• Respect robots.txt: Honor search engine crawling policies
• Terms of Service: Users are responsible for complying with search engine ToS
• Purpose: Designed for legitimate search aggregation, not mass data scraping

Data Handling

• No Personal Data: Tool does not collect or transmit user personal information
• Local Execution: All operations run locally, no external data transmission
• Session Isolation: Cookies are session-specific and cleared after use
