developer tools

Multiplayer is a local debugging agent for developers that connects coding agents to production data so they can fix application bugs automatically. The site highlights runtime debugging, issue deduplication, and integrations with tools like Claude Code, Codex, and Copilot.

A Claude Code skill pack with 171 structured reasoning methods drawn from historical thinkers, designed to route different problem types to specific procedures.

An experimental programming language and compiler built for agent workflows, with CLI commands for parsing, checking, graphing, repair planning, and JSON-based inspection output.

A daily AI intelligence journal for builders, covering notable model, tooling, and release updates in a short sourced digest.

An Android-focused on-device AI agent fork that can automate phone actions, run workflows and schedules, and be controlled locally or through Telegram.

HookGuard is a CLI security scanner for AI coding agent configuration files. It looks for malicious hooks, invisible Unicode, credential exfiltration patterns, and prompt-injection text in files like CLAUDE.md, AGENTS.md, Cursor rules, and GitHub Copilot instructions.

Lowdefy is a config-first web stack that lets AI generate reviewable YAML for full-stack apps and can run AI agents that call existing endpoints as tools.

A multi-lens code review pipeline for Claude Code that runs parallel review passes, validation gates, optional Codex review, an auto-fix loop, and interactive walkthroughs for findings.

Rig is a macOS sidecar for Ghostty that helps engineers create, focus, arrange, and track terminal sessions across projects and coding harnesses. It manages real Ghostty windows with AppleScript and macOS Accessibility APIs, and includes a demo plus build/release scripts.

Aion is a collaborative coding game where AI agents propose code diffs to a live game, vote on changes, and ship the winning diff server-side. It includes an MCP endpoint so agents can connect, read the rules, clone the repo, and submit proposals.

A hands-on workshop repository that walks developers through building a small GPT-style language model from scratch, including tokenization, transformer blocks, training, and text generation.

A local CLI for Claude Code users that turns repeated corrections into evidence-backed CLAUDE.md rules, with a curated rule pack mined from Claude Code issue history.

UserRank is a privacy-focused AI scanning and ranking app for builders that surfaces the AI tools, practices, and workflows people actually use. It supports scans from Claude, ChatGPT, and related tooling, and shares aggregated names and counts rather than raw local data.

A public security leaderboard for AI coding agents, showing 9 benchmark tests across multiple harness versions with dates, outcomes, disclosures, and re-test status.

A defensive AI auditing API for checking structural coherence, semantic rupture, and interaction stability, with a public demo, API docs, SDK install steps, and paid plans.

A spec-driven workflow for AI coding agents that uses reviewed specs, isolated worktrees, and gated commits to turn ideas into verified pull requests.

A CLI code review tool that inspects an agent’s session, not just the diff, to check whether it did what you asked, what it decided on its own, and whether its claims match the code.

A tiny desktop utility that shows remaining GitHub Copilot credits in the macOS menu bar or Windows system tray, using GitHub CLI login and no token storage.

Hapsland is a developer tool that gives coding agents realtime semantic review on code changes, with privacy-aware request scoping and feedback loops back to the agent.

HDTP is a protocol specification for agent-to-agent communication on behalf of people, centered on certificates, contact approval, per-caller permissions, and sealed end-to-end calls.

A small open model trained to turn English requests into Bash commands, with published training data, GGUF weights, and benchmark results.

Graphene is a data analytics framework built for coding agents, with a CLI, SQL-based semantic models, and Markdown pages for dashboards and reporting.

ToolHub is a self-hosted open-source platform that turns scripts into AI tools and organizes them in a hierarchical tree for agents to browse and execute. The page shows architecture notes, execution flow, screenshots, and a live demo/web client reference.

Jev AI is an interactive playground and API for typed AI decisions, with yes/no, choice, and scoring outputs plus confidence signals for routing, moderation, and other workflow decisions.
