developer-tool

Open-source collection of AI agent skills for Kotlin projects, with skill naming guidance, installation options, and examples for Claude Code and Codex.

An experimental programming language and compiler designed for LLM-written code, with a Python-based toolchain that compiles to native macOS binaries. The repo also includes a full NES emulator written in Laze and usage examples for both the compiler and emulator.

A Julia-based projectional editor for structured data with multiple editable views and an AI assistant that edits the same underlying data.

Drawgent is a coding agent that works on a live Excalidraw canvas, aimed at turning sketches and diagrams into code. The page shows a real project with a README-driven quick start, demo section, setup command, and detailed notes on how the agent interacts with diagrams and code.

Cloudflare’s changelog post announces optional OAuth scope selection for Wrangler and the Cloudflare API MCP server, letting users grant only the permissions they need during authorization.

A Claude Code skill that rewrites Claude’s responses through Gemini to strip out the over-polished, BuzzFeed-like tone and output plainer English.

An MCP server that converts images into ASCII art so text-only LLMs can attempt image interpretation. The README includes a short explanation, example setup, and a clear description of its limitations.

A standalone CLI coding agent from Warp that runs in any terminal and supports multi-model routing, persistent sessions, full-screen terminal apps, and cloud-agent handoff.

Whitman is a Rust CLI for selecting an AGENTS.md profile and linking it into the current project. It supports interactive profile browsing, profile creation, and safe symlink handling across local projects and Git repositories.

A routing skill that helps coding agents choose the most token-efficient tool for a task instead of reading whole files or dumping verbose output into context. It recommends tools like serena, graphify, rtk, caveman, or plain Read/Grep/Bash depending on the job.

A macOS menu bar app that uses Apple Vision OCR to find approval buttons like Run, Fetch, or Retry and clicks them automatically for agent workflows.

An open-source probabilistic spreadsheet that lets cells hold distributions, confidence intervals, and ranges instead of single values, with formulas that propagate uncertainty.

Pu.sh is a lightweight coding-agent harness delivered as a shell script. The page shows a direct install-and-run flow, a no-dependency setup, and links to GitHub, docs, and an MIT license.

A PHP framework built around the Action-Domain-Responder pattern, with a small core and an emphasis on code that humans and agents can both follow.

Open-source AI SEO agent and technical optimization suite for coding agents and SEO workflows. The repo describes support for multiple AI environments, modular sub-skills, site crawling, schema validation, indexation workflows, and install paths for local use.

A cross-platform CLI release for switching between isolated Claude Code accounts on Linux and macOS without re-login, with per-profile storage and Keychain-backed credentials on macOS.

An open-source multi-agent coding framework that uses a commit-bound project graph to scope worker tasks, replay failed runs, and merge accepted diffs through ordered Git reconciliation.

A notes app for Mac, iPhone, and iPad that syncs through iCloud and mirrors notes to local Markdown files for editing, backup, and workflow integration.

A browser-based showcase of nine classic demoscene effects implemented across thirteen languages, with pixel-identical output and side-by-side code comparison. It presents the code next to the rendered effect and highlights optimization steps, framed as a project built by an organization of AI agents.

A technical tutorial that walks through building a coding agent in Python, including tool calling, file editing, shell execution, web search, and permission prompts. It includes code snippets, a demo workflow, and a linked GitHub repository with the full implementation.

A GitHub repo that teaches users how to write and debug evals through an agent-guided skill called learn-evals. It includes setup steps, exercises, examples, and a path to install the skill in other projects.

A pure Rust code-assist engine focused on AST safety checks, multi-agent symbol coordination, taint tracking, incremental parsing, and MCP integration. The repository page includes an overview, performance claims, architecture notes, and configuration references.

Real-time signal engine and MCP server for AI agents, quantitative workflows, and climate risk pipelines. The page highlights native MCP tools, live data ingestion, and a structured wire format aimed at reducing token usage.

A VS Code extension that turns code editor cursors into a real-time music visualizer using microphone or system audio input.
