smithy-lang/smithy-typescript

Code Generators That Turn Smithy Models Into TypeScript SDKs — This repo is the reference TypeScript code generator for Smithy models, producing both client and server scaffolding. The typescript-client-codegen plugin builds extensible, type-safe clients targeting Node.js 20+, browsers, and React Native, while typescript-server-codegen generates server-side interfaces. Useful for teams defining APIs with Smithy who want generated, strongly typed TypeScript SDKs instead of hand-written ones.

Smithy code generators for TypeScript. (in development)

profullstack/hqtui

High Quality Terminal UI for TypeScript — btop-grade terminal dashboards with a one-import API, dark by default, zero runtime dependencies.

aws/agentcore-cli

A unified CLI and TUI for Amazon Bedrock AgentCore — This official CLI wraps Amazon Bedrock AgentCore's APIs into both a scriptable command-line tool (with JSON output for CI and coding agents) and an interactive TUI for creating projects, deploying agents, and chatting with them. It replaces the separate Python Starter Toolkit, handling execution roles and streaming so developers can go from zero to a deployed agent via simple commands.

The terminal experience for AgentCore!

winnin/farol

A risk map for pull requests, sitting after your AI reviewer — farol is a free CLI and GitHub Action that runs after AI code review to show approvers which files carry the real risk of a merge, what they reach, diff coverage, and contract breaks. It relies on static analysis rather than model guesses, covering TypeScript/React, Go, and Python, and runs in shadow mode so it never blocks merges.

Know the risk of merging a pull request, and where it lives. Free, open-source CLI and GitHub Action: after your AI review, farol shows the riskiest files, what they reach, diff coverage and contract breaks. TypeScript/React, Go, Python.

GenerativeAgents/claude-code-book-chapter8

Sample code for Chapter 8 of a Japanese Claude Code book — This repo holds the Chapter 8 sample code and prompts for the Japanese book 'Practical Claude Code' published by Gijutsu-Hyoron-sha. It ships a Dev Container setup that installs Node.js LTS and the latest Claude Code, letting readers run the examples without manual environment setup. Prompts may be updated based on reader feedback, so content can differ slightly from the printed book.

nulab/bee

Command-line tool to view and manage Backlog

HamedMP/matrix-os

A cloud computer where AI agents attach via CLI and build the OS itself — Matrix OS is a hosted cloud workspace combining browser desktop, files, terminals, apps, and integrations, accessible from any browser. Its CLI lets agents like Claude, Codex, GitHub CLI, or Hermes attach directly to your VPS. The tagline captures the twist: the system is built largely by AI agents operating within it, not just for them.

rbartoli/agent-usage-guard

A Claude Code mod that stops usage-window burnout before it happens — agent-usage-guard runs inside Claude Code and intercepts subagent fan-out, heavy-context prompts, and retry loops before they drain your five-hour usage window. It reads your plan's live usage and counts agents across sessions, then prompts you in Claude Code's own dialog before spend occurs rather than after. Useful for anyone who's burned through a usage window via runaway subagents or retries.

Jared-woodruff/OMF-2097-Remastered

Classic DOS robot-fighter reborn with one-key HD/retro toggle — This TypeScript/WebGL2 reimplementation of 1994's One Must Fall 2097 plays the original game files while adding HD art, widescreen arenas, replays, a training lab, and OMF Studio mod tools. An F2 key swaps classic and remastered visuals instantly, even mid-fight. Free for Windows, macOS, Linux and browsers.

One Must Fall 2097, remastered: the 1994 robot fighting classic rebuilt in TypeScript and WebGL2, playing the original game files.

Free, for Windows, macOS, Linux and the browser.

yuiseki/map-from-scratch

A from-scratch skill that lets AI agents build one-off, minimal map renderers — Instead of one general map engine, this gives AI agents a skill and harness to rebuild the smallest, fastest renderer for each specific request, picking language/API/runtime per case (Canvas2D, WebGL2, C+EGL, even microcontrollers). Each example is defined in spec.yaml with measurable requirements and benchmarks that the harness checks pass/fail, drawing on techniques from 48 reference map engines.

BIMvoice/ifcsheet

Browser-based drawing production from existing IFC models — IfcSheet takes an IFC file you already have and focuses purely on producing plans, sections, elevations and sheets: dimension, tag, hatch, lay out on A0-A4 sheets and export to PDF/SVG/DXF. Tags track elements by GlobalId so renames propagate automatically. Built by BIM practitioners frustrated with how slow drawing production is in Bonsai, it targets architects, engineers and BIM coordinators who need openBIM deliverables without vendor lock-in.

Draw, dimension and sheet IFC models in the browser. Plans, sections, annotations, PDF and DXF. Open source, MPL-2.0.

fixture-inc/swarmatory

A shared feed where your team's coding agents coordinate work — Swarmatory gives coding agents a shared chatroom to find overlapping work, post updates, and decide who takes the lead, with humans reading along. It deploys as a single Cloudflare Worker plus D1 database behind Cloudflare Access, makes no model calls, and agents connect over plain HTTP via a skill file—no extra install needed.

A shared chatroom/feed for your team's coding agents to talk and coordinate their work.

chaharnishant11/notewell

A reverse-engineered teardown of Granola, plus an open re-implementation — This repo documents how Granola's desktop app captures meetings without a bot and turns notes into polished summaries, based on a static analysis of the macOS build. It pairs the teardown with notewell, an original open-source re-implementation covering audio capture, cloud/on-device ASR, and server-side prompts.

mizchi/mutator

Mutation Testing That Only Reruns What Your Diff Touched — mutator brings mutation testing to Vitest projects using oxc-based instrumentation and in-memory transforms, with per-test coverage and position-independent result caching so unchanged code is never re-run. Its `--since <ref>` mode scopes mutant execution to a git diff, making it practical for fast CI reruns. The README positions it as a faster alternative to StrykerJS for TS/JS projects.

JulienAvezou/Slowth-Money

A privacy-first desktop app that plans Canadian savings goals locally — Slowth Money is a local-first Electron app that tracks TFSA/FHSA/RRSP progress with deterministic math and AES-256-GCM encrypted SQLite storage.
