Developer Tools / Testing & Code Review
An open-source code-review training repo with 24 AI-written bug katas in Python and JavaScript. It includes runnable tests, fix-and-verify workflows, and GitHub Actions grading for forks.
The page clearly presents a concrete AI-adjacent developer project: a training repo for spotting bugs in AI-generated code. The snapshot shows a specific workflow, multiple language exercises, installation and usage notes, examples, and grading via GitHub Actions, which is enough for a useful public listing.
The snapshot does not show the full README contents for every kata, so visitors cannot tell how consistent the difficulty or lesson design is across all 24 exercises. It also does not show a live demo or screenshots of the scoring workflow beyond the text description.

CodeGraph is a local code knowledge graph for AI coding agents like Claude Code, Cursor, Codex, OpenCode, and Hermes Agent. It aims to cut token use, tool calls, and runtime by letting agents query pre-indexed code structure instead of scanning files repeatedly.
Mercemur is a store automation platform with three interfaces: a REST API, an MCP server for AI agents, and a CLI for editing storefronts as files. The docs show authentication, scopes, rate limits, error handling, pagination, idempotency, and a large API surface for catalogue, orders, customers, pricing, and money.
Lumae is a free native macOS screen recorder and screenshot tool for polished demos, with automatic zooms, cursor smoothing, motion blur, captions, voiceover, and annotated screenshots. It also exposes editing commands over MCP so agents like Claude Code or Claude Desktop can edit projects directly.
A zero-dependency C++23 CLI and MCP server that gives coding agents a ranked map of a repository, including call context, blast radius, and tests to run.
