PromptKit
A composable, version-controlled prompt library that snaps together personas, reasoning protocols, output formats and templates into engineered prompts for tasks such as bug investigation and code review.
PromptKit treats prompts as engineered artifacts rather than copy-pasted, untested text, offering 157 components -- 15 personas, 48 protocols, 21 formats, 5 taxonomies and 64 templates across four pipelines -- for software, hardware, mechanical, RF, firmware and protocol engineering tasks.
Three interactive workflows form a domain-agnostic lifecycle and each runs directly inside an LLM session with built-in challenge and verification steps: a spec-extraction workflow scans a repository and extracts structured requirements, design and validation specifications from existing code; an engineering workflow propagates a requirements change through specs and implementation with adversarial alignment audits at each stage; and a maintenance workflow periodically detects where code and specs have drifted apart and corrects both. It requires Node.js 18 or newer and Git, and is installed with npx.
