System Instructions That Work
Build system instructions using a structured template, then compare vague vs precise instructions side-by-side to see the difference in agent behaviour.
Instruction Template Builder
Construct system instructions section by section. Each section targets a specific aspect of agent behaviour. Fill them in to generate a complete, structured system prompt.
Key insight: Vague instructions like "be helpful" produce unpredictable behaviour. Structured instructions that define identity, boundaries, tools, output format, and escalation rules turn an LLM into a reliable agent that behaves consistently across thousands of interactions.
