Using LLM in the shebang line of a script

Simon Willison published a TIL (Today I Learned) on 11th May 2026, demonstrating how to use his LLM tool in the shebang line of scripts. The simplest approach leverages LLM fragments, but more advanced usage includes tool calls via the -T option and direct execution of YAML templates defining Python functions. A debug flag (--td tools) outputs tool details. The post also references a complex example using the Datasette SQL API to answer questions about blog content. Willison offers a $10/month sponsorship for a curated email digest of monthly LLM developments.
