Keen Code
Hello community! I am here to share a coding agent I have built solo from scratch using agentic engineering. Written in Go, it's a proper coding agent, has features you expect from a useful agent for your daily work, with a minimal and simple UI. I have named it Keen Code. The repo is here: https://github.com/mochow13/keen-code Even though it started as an experiment, it is now a full-fledged coding agent for real software engineering work. It supports multiple providers, skills, MCPs, multi-agent orchestration through subagents, automatic compaction, etc. I have been…

What it does
Keen Code is an open-source, context-aware and efficient CLI coding agent written in Go. Three aspects stand it out from other similar products: - It was built from scratch by coding agents, with the full prompt/design trail preserved and shared in the repo. - It uses turn memory to keep multi-turn sessions lean which saves context significantly. - It maps MCP servers to lazy-loaded Skills instead of stuffing large schemas into context upfront. This again saves context in mult-MCP setting.
A CLI-based minimal coding agent with lean context management and skill-driven MCP support. Swap between Gemini, OpenAI, Anthropic, DeepSeek, and more — no lock-in. Connect any MCP server to extend the agent with external tools and data sources. Custom slash commands that run specialized sub-agents — review, security, refactor. Skill-driven MCP servers — combine slash commands with external tool integrations. Six tools out of the box: read, write, edit, glob, grep, and bash. Lean cross-turn context — compact summaries instead of raw toolfrom mochow13.github.io

Paseo – Beautiful open-source coding agent interfaceJun 2026 · github.com · ▲92Hey HN, I'm Mo. I've been building Paseo, an open source environment for running Claude Code, Codex, and OpenCode across desktop, mobile, web, and CLI. It started last September as a push-to-talk voice interface for Claude Code. I wanted to talk to an agent while going on walks. Then I wanted to see what it was doing. Then text it when I couldn't talk. Then review diffs, run multiple agents, and manage work across machines. After a lot of iteration, it turned into a broader environment. The basic model is: - A daemon runs on your machine (MacBook, desktop, VPS, etc.). - Clients connect to it…
- 1D143.dev – we open-sourced our internal coding-agent infrastructureJun 2026 · ▲13
We just open-sourced the internal system we built at Assembled for running coding agents as a team. Coding agents worked well for individual engineers, but the surrounding workflow was a bit of a mess. We generally found that many engineers had different MCP connections and context for their agents, personal automations running that other people couldn’t access, and very little introspection for what a human’s input into the coding agent looked like. So we built an internal system that converted coding agents into shared team infrastructure. The system runs Codex, Claude Code, OpenCode, and…

Homebrew 6.0.0▲1,481Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!

Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
