Agentic prompts are the most important code you're not engineering. PromptKit fixes that — composable, version-controlled prompt components (personas, protocols, formats, templates) that snap together into reliable, repeatable prompts for bug investigation, design docs, code review, security audits, and more. Works with any LLM.
PromptKit is a version-controlled library of reusable prompt components for engineering work, including personas, reasoning protocols, output formats, and task templates. Engineers use it to create repeatable prompts for activities such as specification work, debugging, code review, security audits, and change management across multiple engineering fields. The catalogue add-ons provide agent workflows for using this prompt-engineering system.
