This is particularly useful when trying to use domain specific knowledge in the solution, in order to improve its overall performance.Some examples include:Including dynamic few shot examplesFinding misspellings in proper nouns to use as column filtersWe can create separate tools which tackle these specific use cases and include them as a complement to the standard SQL Toolkit. Let's see how to include these two custom tools.Including dynamic few-shot examples‚ÄãIn order to include dynamic few-shot examples, we need a custom Retriever Tool that handles the vector database in order to retrieve the examples that are semantically similar to the user‚Äôs question.Let's start by creating a dictionary with some examples: # few_shots = {'List all artists.': 'SELECT * FROM artists;',#              "Find all albums for the artist 'AC/DC'.": "SELECT * FROM albums WHERE ArtistId = (SELECT
