Deferred Tool Loading

About this workflow

Stop paying context for tools the task never needs: load a core set eagerly and expand the toolset on demand.

Best for

• •Recurring tasks you currently copy-paste between tools.
• •When a single prompt isn't enough — you need a chain where output(n) feeds prompt(n+1).
• •Fork and adapt if your inputs differ materially from the author's use case.
