Agent System Prompt Starter
Turn agent ideas into dependable working assistants faster, with fewer prompt rewrites, tool mistakes, and handover gaps between builders.
What it is
This starter helps teams move from a loose agent idea to a dependable operating assistant without spending days reinventing the prompt structure. It gives every agent a clear role, tool-use rules, guardrails, and output standards, which reduces drift, makes testing easier, and helps non-technical stakeholders understand what the agent is supposed to do.
When to use it
- You're standing up a new AI agent or assistant and want a solid starting point.
- Your agent misuses tools, ignores instructions, or drifts off-task.
- You want a consistent house style across several agents on your team.
How to use it
- 1Download the Markdown file and open it in any text editor.
- 2Copy the scaffold into your agent's system-prompt field.
- 3Replace each [PLACEHOLDER] with your agent's role, available tools, and rules.
- 4Test against real tasks, then tighten the guardrail and output-format sections to taste.
