Graft gives coding agents a prebuilt map of the repository
trailhq/Graft
A TypeScript CLI that parses a codebase with tree-sitter into linked files an agent can read, with its own benchmarks claiming fewer tokens and more fixes.
M3E Canvas turns a Material 3 mockup into a prompt for your agent
lnkiai/m3e-canvas
A browser editor for Material 3 Expressive screens that writes a long, specific build prompt for Claude Code or Codex. No backend, and one static page.
codex-chatgpt-web runs Codex on your ChatGPT subscription
miuuyy/codex-chatgpt-web
A launcher that drives the ChatGPT website from a hidden browser, presents it to Codex as a model, so coding turns draw on chat limits instead of Codex quota.

Eighteen source types in, twenty-two targets out, with automatic conflict detection and an AI scan that emits one config per framework it finds in your project.
AutoHarness writes its own skills from your sessions
tigerless-labs/autoharness
A self-maintaining skill layer for Claude Code that distills skills from real work, merges near-duplicates, and prunes what stops getting used.
Planning with Files keeps the plan when the context dies
OthmanAdi/planning-with-files
Three markdown files on disk, re-injected every turn, so an agent survives /clear, compaction and crashes without asking you to restate the goal.
Chrome DevTools is now an MCP server for your agent
ChromeDevTools/chrome-devtools-mcp
Google's own server hands a coding agent performance traces, network inspection, console messages with source-mapped stacks, and Puppeteer automation.
DevSpace gives ChatGPT a tunnel to your actual machine
Waishnav/devspace
A self-hosted MCP server that lets a web chat read, edit, search and run code in your real local projects, with no upload and a password only you hold.
Understand Anything turns a codebase into a graph you can ask
Egonex-AI/Understand-Anything
A multi-agent pipeline maps every file, function and class into an interactive graph with plain-English summaries, guided tours and a business-domain view.
ego lite is a browser you and your agent share
citrolabs/ego-lite
Instead of driving a separate browser, agents get their own Spaces inside yours, so they reach your real logins without stealing the tab you are reading.
GSD Core fights context rot with fresh-context subagents
open-gsd/gsd-core
A five-step phase loop for coding agents that runs research, planning and execution in clean 200k-token contexts so the main session never fills up.
opencodex puts any model behind Codex and Claude Code
lidge-jun/opencodex
A local proxy that translates the Codex Responses API into whatever your provider speaks: streaming, tool calls, reasoning tokens and images, both ways.
Ponytail makes your coding agent stop over-building
DietrichGebert/ponytail
An agent skill that enforces YAGNI and reaches for native platform features first. Its own benchmark walked back its earlier, more flattering numbers.
Open Code Review: Alibaba's internal review bot, opened up
alibaba/open-code-review
A Go CLI that reviews git diffs with a hybrid of deterministic pipelines and an LLM agent, and claims a ninth of the tokens a general agent spends.
Epic open-sourced Lore, a version control system for artists
EpicGames/lore
A Rust VCS from Epic Games built for repositories where the code is the small part: large binary assets, huge teams, free branching, tamper-evident history.
