Playing around with a Kent Beck-inspired prompt today:
Before implementation, look for opportunities to prefactor the code to make the implementation easier. "Make the change easy, then make the easy change."
MAKE SURE YOUR CLAUDE AGENTS ARE SECURE WITH THIS ONE SHORT PROMPT:
“Review this Claude agent for security risks: identify prompt injection vectors, unsafe tool permissions, data exfiltration paths, jailbreak susceptibility, secret leakage, overbroad system prompts, insecure code execution, and missing output validation. Return only concrete vulnerabilities with severity and fixes.”
Thank me later.
a prompt I've been using a lot recently:
implement <SPEC> and while you do, keep a running implementation-notes.html file (or markdown) with decisions you had to make weren't in the spec, things you had to change, tradeoffs you had to make or anything else I should know
El equipo de Anthropic acaba de publicar cómo hacer prompts en Claude para sacarle el máximo partido.
