The\n`get_skill` tool description covers persisting skills locally if your client\nsupports it.\n\n## Dashboard Creation Workflow\n\nBefore creating or updating a dashboard with `set_dashboard`, check existing\nTerminal dashboards first with `search_terminal` unless the request is clearly\nunrelated to public Terminal dashboards. If a relevant dashboard exists, call\n`get_terminal_results` to inspect its chart manifest, SQL, and latest\nprecomputed rows, then use that context as the baseline for any new Explorer\nqueries or dashboard elements.\n\n## Row Limits\n\nEach query run executes under a SQL LIMIT. The platform limit is\n250,000 rows, and it applies to `run_sql_query`,\n`create_explorer_query` and `run_explorer_query` alike. An organization can be\nset lower, and a smaller LIMIT in the SQL wins, so the run's real limit comes\nback as `row_limit` on `get_query_run_results`.\n\n`get_query_run_results` returns a page of\n1,000 rows by default, not the whole\nresult: `row_count` is what the run stored and `data` is the page. When\n`row_count` equals `row_limit`, the run stopped at its limit and the true total\nis unknown. Say so, and never tell the user that a query link or a CSV download\nholds rows the run never fetched. Aggregate in SQL when the answer needs more\nrows than the limit.\n\n## Documentation\n\nhttps://docs.allium.so/ai/mcp\n"}}
