Tool Descriptions That Steer the Model

Treat tool descriptions as prompt engineering: when-to-use guidance, negative cases, and worked examples that fix tool-choice errors.

Final output

No inputs required — hit Run to stream each step in order.

Each step streams from its model and feeds the next. BYOK — you pay your provider directly. Add a key in Settings if a step needs one.

Step 1 · Fix the confusions you actually have, not hypothetical ones.

Step 2 · Purpose, use-when, avoid-when, example - in that order, tightly.

Step 3 · Tool choice is testable - so test it.

•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.
