Code quality

A Java metaprogramming library that parses source files into a full AST and provides an API for analyzing, rewriting, transforming and transpiling Java source code, supporting Java versions up to 25.

• Code quality

A local MCP server that gives your own ChatGPT session read, search, edit and review access to repositories you explicitly allow on your machine, with bounded local code-intelligence tools for impact analysis and change review.

• MCP servers
• Code quality

A context and harness engineering system for Claude Code and OpenAI Codex that enforces quality gates, keeps durable project context across sessions and compaction, and turns completion claims into verified evidence.

• Agent skills
• Code quality

A multi-agent orchestration framework that mechanically enforces engineering rules on AI coding assistants, gating every code-changing turn on checks that reviewers ran, memory updated, and shipped files are supply-chain intact.

• Agent frameworks
• Code quality

A zero-dependency C++ command-line tool and MCP server that maps a codebase for an AI coding agent before it reads the repository, then checks a proposed edit's blast radius, the tests that reach it and where its quality got worse.

• Agent memory
• Code quality

An agent-first linter for Tailwind design systems that lets you define allowed component styling rules and gives a coding agent guidance, not just an error, when it breaks one.

• Code quality
• UI kits

A set of PHP_CodeSniffer rules that check PHP code against the official WordPress coding conventions.

• Code quality

A terminal code-review tool with vim-style keybindings that turns a diff into PR-style comments and can push a real review to GitHub, GitLab, Gitea, Bitbucket, Azure DevOps, or Gerrit.

• Git
• Code quality

An opinionated set of Oxlint rules that reject low-evidence and low-signal TypeScript and JavaScript patterns, meant to be vendored and adapted rather than installed as a fixed dependency.

• Code quality

A set of Java libraries implementing a parser and abstract syntax tree for Java 1.0 through Java 25, with an add-on symbol solver for resolving declarations and types.

• Code quality
• Libraries

A TypeScript wrapper around the TypeScript Compiler API that makes it easier to programmatically navigate and manipulate TypeScript and JavaScript source code.

• Code quality
• Libraries

A copy-paste and duplicate code detector for more than 220 languages, with a Rust engine, that also finds dead code, complexity hotspots, and a duplication trend.

• Code quality

A self-hosted codebase intelligence tool that indexes code, dependency graphs, git history, tests, and documentation to give agents and developers cited answers.

• Agent memory
• Code quality

A metaprogramming code generator for Swift, built on SwiftSyntax, that removes boilerplate by generating code such as mocks, equality and Codable conformances from templates.

• Code quality

A local, browser-based review surface for AI coding agents that opens a plan, HTML artifact or code diff for markup, then sends the feedback straight back to the agent.

• Coding agents
• Code quality

A review-first terminal diff viewer for agent-authored changesets, showing inline AI annotations beside the code in split, unified or responsive layouts.

• Terminals
• Code quality

An open-source, AI-powered code-review agent that runs as a GitHub Action, a local CLI or a webhook, reviewing, improving and answering questions about a pull request with a single LLM call per tool.

• Git
• Code quality

A Claude Code plugin that runs OpenAI Codex from inside a Claude Code session, for reviewing code or handing off tasks to Codex without leaving the existing workflow.

• Agent skills
• Code quality

An opinionated Python code formatter that reformats files in place with minimal configuration, producing consistent formatting across projects.

• Code quality

An AI-powered code review CLI that reads git diffs and sends changed files to a large language model agent with tool access, producing line-level review comments while combining deterministic checks with agent reasoning.

• Code quality

Front-End Checklist turns front-end best practices into a reviewable system of 385 rules across eleven categories, usable through a website, an MCP server for agent workflows, or directly inside its README.

• Code quality

An agent skill that makes AI coding agents write less code by checking, before writing anything, whether the code is needed, already exists, or is covered by the standard library or platform.
