Prompt Library: Designing Tools
Designing Your Tool Inventory
Help me design the tool list for an agent. WHAT IT DOES: [description]. SYSTEMS IT CAN REACH:
[list]. THE TASK TRACE: [paste your trace]. Propose a tool list, for each, a name and a
description of four sentences or fewer covering what it does, when to use it, what it does NOT
cover, and what it returns on failure. Mark each READ or WRITE; for writes, say whether
reversible and what the worst wrong call would do. Flag any two tools a model might confuse
and rewrite their descriptions so it can't. Is anything too broad, particularly any write
tool that should be split so we can control the parts separately? And which tools could we cut
from a first version?
