Tavily Web Skill

Trigger Conditions & Endpoint Selection

Choose Tavily endpoint based on user intent:

• search: Need to "search web / latest info / find sources / find links"

• extract: Given URL(s), need to extract/summarize content

• crawl: Need to traverse site following instructions and scrape page content

• map: Need to discover site page list/structure (without full content or metadata only)

• research: Need structured research output following given output_schema

Recommended Architecture (Main Skill + Sub-skill)

This skill uses a two-phase architecture:

• Main skill (current context): Understand user question → Choose endpoint → Assemble JSON payload

• Sub-skill (fork context): Only responsible for HTTP call execution, avoiding conversation history token waste

Execution Method

Task parameters:
- subagent_type: Bash
