PromtExpress open-sources MIT prompt library: JSON templates, CI validator, seeks contributors
A developer behind the paid prompt-generation SaaS PromtExpress released the open-source portion of its prompt library under MIT on GitHub. The library ships JSON prompt templates for text, code, image, video, audio, and music, validated in CI by a zero-dependency checker, with TypeScript/Python SDKs and a CLI. The author is soliciting contributors and critique of the embedded prompting patterns.

AI Overview
- PromtExpress (a paid prompt-generation SaaS) open-sourced its prompt library under MIT on GitHub with templates for text, code, image, video, audio, and music.
- Each template is a single JSON file with declared variables, a worked example, a language code, and author credit.
- A zero-dependency CI validator enforces that every {{placeholder}} is declared, every variable is used, and IDs match file paths.
- The repo ships TypeScript/Python SDKs and a CLI for the PromtExpress API, usable independently of the product.
- Baked-in patterns include source-quote grounding in meeting notes, labeled PRIMARY/SECONDARY TEXT plus NEGATIVE blocks for image models, required failing inputs in PR reviews, and a POSSIBLE BUG flag in the unit-test template.
- Open 'good first issue' tasks cover Turkish, German, and Spanish translations plus new templates; contributors get GitHub usernames in the authors field.

Library of 1000 structured system prompts built around constraints instead of personas
A library of 1000 structured system prompts for AI coding tools. It operationalizes the author's argument (written up on Medium) that prompts should specify concrete constraints rather than personas like 'act as a senior developer', which force models to guess intent. It targets developers who prompt AI coding tools and get vague or inconsistent output.

Developer shares typed-contract pattern for prompt template variables
A developer on Reddit describes a pattern for treating prompt template variables as a typed contract, extracted mechanically from the template itself. This prevents runtime errors from mismatched data shapes and improves code reliability.
