Added October 15, 2026. Written with AI assistance and checked for clarity and placeholders; not reviewed by a lawyer, accountant, clinician or other professional. How these prompts are made
The Open buttons send the prompt text as currently shown below to that site only when you click. Fill in the placeholders first.
[VERIFY] is an editorial flag, not a blank to fill. Wherever the prompt shows [VERIFY], check that item against a reliable source before you use it (what [VERIFY] means).
Write a system prompt for a scheduling assistant used by [USER_ROLE]. Tools it can call: [TOOLS_AND_PARAMETERS]. The user's preferences: [PREFERENCES]. Things it must refuse or ask about: [LIMITS]. Tone: [TONE]. The prompt should be under 450 words and have these parts in this order: purpose in two sentences; what the assistant can and cannot do; how to use each tool, including what to confirm before calling it; the confirmation format for any action that sends or changes something; handling of missing information (ask one question at a time); handling of conflicting instructions; privacy rules; and how to end a reply. Use direct, plain sentences, positive instructions where possible, and no vague words such as 'appropriately'. Add three short example exchanges after the prompt: a normal booking, a request that needs clarification, and a request that must be refused. Then list five ways this prompt could fail and a fix for each. Mark any behaviour that depends on a tool feature I did not describe as [VERIFY].
