UPB Forge Framework: An enhanced HTML structure acting as a "Document-as-OS" to guide AI assistants (like Gemini 2.0 flash thinking - 2.5 Pro, ChatGPT 4.1) in complex, context-aware tasks using Prompt IDs, layered instructions, and expert personas for writing, analysis, coding, and game design conceptualization.

An 8-layer cognitive architecture for LLMs with global workspace, active inference, metacognition, recurrent depth, and self-amendment.

A prompt-based AI project runtime for structured activation, roadmap-first execution, active-step artifacts and handoff continuity.

KERNEL Ω est une architecture cognitive unifiée pour LLMs. En fusionnant Graph of Thoughts, Self-Discover et Few-Shot Introspectif, il transforme les générateurs de texte linéaires en moteurs d'inférence réflexifs capables de douter, de s'auto-corriger et de cartographier leur propre pensée.

OpenClaw Agent Configuration Templates - Lightweight prompt engineering framework for AI agents

Production-grade framework for super-prompt engineering. Interactive CLI, cross-platform automation (PowerShell 5.1/7+, bash, zsh), Docker, GitHub Actions CI/CD, and model-optimized YAML templates. MIT License.

A lightweight framework for writing clearer prompts when working with AI systems.

Turn a raw idea into a production-grade LLM prompt — versioned framework with 15 components, pass/fail constraints, and falsifiable success conditions.

The Ultimate Open-Source Blueprint for LLMs using the Stage-Task-Rules (STR) Methodology.

A Spec-Driven Development (SDD) prompt framework for AI coding agents — expert personas debate and agree on every spec before code is written, and decisions, specs, and plans accumulate in a plain markdown + git memory (an LLM-wiki structure, after Karpathy) so the next session resumes exactly where the last stopped.
