Fixes a Looker dashboard that got slower because one explore fans out into many queries per tile, by removing the fanout source and pre-aggregating. Use when tile runtimes grew after a model change and queries multiply in the logs. Not for a dashboard slowed by a warehouse wide slowdown affecting all tools.
Fixes kernel OOM when a notebook query returns millions of rows by pushing aggregation to the database, reading in chunks, or sampling. Keeps large results out of kernel memory. Not for OOM caused by model training or large in-memory joins, and not for slow queries that return small results.
Fixes Brave Search API 422 on the goggles parameter: format, encoding, and when to drop it. Use when queries with goggles 422 but the same query without goggles works. Not for 401 auth or 429 rate limits.

Fixes agents timing out on answer library search with retries, fallbacks, and caching. Use it when index slowness kills searches. Not for ranking issues.
Fixes DuckDB conversion errors when reading CSV or Parquet data where a string value lands in an integer column. Covers declaring explicit column types, mapping null markers, and cleaning dirty values before casting. Use when read_csv or a cast fails on string-to-INT conversion.

Fixes QuestDB 'out of memory' failures on large joins. Use when a join over wide time ranges exhausts memory. Walks through bounding both sides with timestamp filters, chunking the range, shrinking the join width, and raising memory only after bounding. Key trigger: the query dies with out of memory while each side ru…

Fixes Polars ShapeError when hstacking dataframes with mismatched row counts. Use when pl.concat how='horizontal' fails, when an agent joins frames side by side without aligning, or when one frame got filtered and the other didnt. Not for vertical concat errors, for join key mismatches, or for schema conflicts.
