+triggers:
+  keywords: [web, search, internet, online, fetch, url, webpage, website, current, recent, latest, news, documentation, brave]
+  verbs: [search, fetch, get, find, lookup, retrieve]
+  patterns:
+    - "https?://"
+    - "www\\."
+    - "search.*for"
+    - "look.*up"

+
+# web
+
+## 🎯 Triggers
+**When user wants to:**
+- Search the internet
+- Get current/recent information
+- Fetch content from a URL
+- Access online documentation
+
+**Skip when:**
+- Answer is within knowledge cutoff
+- Local file operation
+
+## Scripts
+
+### search
+**What:** Search the web using Brave Search API
+**Pattern:** User wants to search → `script_run web search --query "USER_QUERY" --json`
+**Example:** "Search for python tutorials" → `script_run web search --query "python tutorials" --json`
+
+### fetch
+**What:** Fetch and convert web page to markdown
+**Pattern:** User provides URL → `script_run web fetch --url "USER_URL" --json`
+**Example:** "Get https://example.com" → `script_run web fetch --url "https://example.com" --json`
+
+## Quick Reference
+```
+User: "Search for X"          → script_run web search --query "X" --json
+User: "Fetch https://..."     → script_run web fetch --url "https://..." --json
+User: "Find recent news on X" → script_run web search --query "X news" --json
+```
+
+## Requires
+- `BRAVE_API_KEY` environment variable for search
