All good
- ✓check_stack: Answered with an error, probably because of our sample input: check_stack needs two to ten tools, for example {"tools": ["Shopify", "Klaviyo"]}. For one tool, use get_tool.

- ✓get_cdp: Worked (155 ms)
- ✓list_cdps: Worked (181 ms)
- ✓search_directory: Answered with an error, probably because of our sample input: Give something to search for: a query, a CDP or a category, for example {"query": "snowflake"}.
- –get_tool: Not run: labeled read-only, but its description says "sends", which usually means it changes something. Skipped to be safe: if it only reads, a clearer description helps AI apps too, or test again with --owner
