+name: tavily-search
+description: "Web search via Tavily API (alternative to Brave). Use when the user asks to search the web / look up sources / find links and Brave web_search is unavailable or undesired. Returns a small set of relevant results (title, url, snippet) and can optionally include short answer summaries."
+---
+
+# Tavily Search
+
+Use the bundled script to search the web with Tavily.
+
+## Requirements
+
+- Provide API key via either:
+  - environment variable: `TAVILY_API_KEY`, or
+  - `~/.openclaw/.env` line: `TAVILY_API_KEY=...`
+
+## Commands
+
+Run from the OpenClaw workspace:
+
+```bash
+# raw JSON (default)
+python3 {baseDir}/scripts/tavily_search.py --query "..." --max-results 5
+
+# include short answer (if available)
+python3 {baseDir}/scripts/tavily_search.py --query "..." --max-results 5 --include-answer
+
+# stable schema (closer to web_search): {query, results:[{title,url,snippet}], answer?}
+python3 {baseDir}/scripts/tavily_search.py --query "..." --max-results 5 --format brave
+
+# human-readable Markdown list
+python3 {baseDir}/scripts/tavily_search.py --query "..." --max-results 5 --format md
+```
+
+## Output
+
+### raw (default)
+- JSON: `query`, optional `answer`, `results: [{title,url,content}]`
+
+### brave
+- JSON: `query`, optional `answer`, `results: [{title,url,snippet}]`
+
+### md
+- A compact Markdown list with title/url/snippet.
+
+## Notes
+
+- Keep `max-results` small by default (3–5) to reduce token/reading load.
+- Prefer returning URLs + snippets; fetch full pages only when needed.
