prompt engineering

Kon is a minimal terminal coding agent with a tiny default prompt, a built-in toolset, and configurable model/provider support. The repo includes install steps, CLI usage, example commands, and configuration details.

An interactive guide and demo for prompt engineering that shows how analogies, examples, and format-matching can improve LLM outputs.

Ponytail is a repository and plugin toolkit that pushes AI coding agents to choose the smallest useful implementation first, favoring stdlib, platform features, and one-line fixes over larger generated code. The README shows installs and usage paths for Claude Code, Codex, OpenCode, Cursor, Windsurf, Cline, Copilot, Ai

Chrome MV3 extension that organizes existing AI tabs into a structured model council for cross-checking prompts across ChatGPT, Claude, Gemini, Perplexity, Merlin, and Grok.

A GitHub repository of system-prompt overrides for Claude Code, aimed at shrinking the always-on prompt and adjusting behavior for Opus 4.7. It includes a detailed rationale, measured prompt-size reductions, and install steps using tweakcc-fixed.

A catalog of design patterns for building agentic systems that verify outputs with evidence instead of relying on self-review. The page explains two main failure modes and presents structured patterns for context, verification, and orchestration.
