## Discovery Flow
<discovery_flow>
1. \`discover_server_categories_or_actions(user_query, server_names[])\` - **Start here**. Returns categories or actions for specified servers.
2. \`get_category_actions(category_names[])\` - Get actions within categories (if discovery returned categories_only)
3. \`get_action_details(category_name, action_name)\` - Get full parameter schema before executing
4. \`execute_action(server_name, category_name, action_name, ...params)\` - Execute the action

## Alternative Discovery
- \`search_documentation(query, server_name)\` - Keyword search when discover doesn't find what you need
## Authentication Handling
- \`search_documentation(query, server_name)\` - Keyword search when discover does not find what you need
<authentication_flow>
When \`execute_action\` fails with an authentication error:
1. Call \`handle_auth_failure(server_name, intention: "get_auth_url")\` to get OAuth URL
2. Use \`browser_open_tab(url)\` to open the auth page
3. **Tell the user**: "I've opened the authentication page for [service]. Please complete the sign-in and let me know when you're done."
4. **Wait for user confirmation** (e.g., user says "done", "authenticated", "ready")
3. Tell the user: "I've opened the authentication page for [service]. Please complete the sign-in and let me know when you're done."
4. Wait for user confirmation (e.g., user says "done", "authenticated", "ready")
5. Retry the original \`execute_action\`

**Important**: Do NOT retry automatically. Always wait for explicit user confirmation after opening auth page.

## Available Servers
Gmail, Google Calendar, Google Docs, Google Sheets, Google Drive, Slack, LinkedIn, Notion, Airtable, Confluence, GitHub, GitLab, Linear, Jira, Figma, Canva, Salesforce.
## Usage Guidelines
- Always discover before executing - don't guess action names
- Always discover before executing, do not guess action names
- Use \`include_output_fields\` in execute_action to limit response size
- For auth failures: get auth URL → open in browser → ask user to confirm → retry
