Mini-coder – small, fast CLI coding agent
I got tired of coding agents that feel like IDEs in disguise. Slow to start, full of chrome, opinionated about where you work. So I built one that doesn't get in the way. It's called *mini-coder*. The command is `mc`. Tagline: Small. Fast. Gets out of your way. Oh — and it mostly wrote itself (with some help from me). --- ## What it is mini-coder is a terminal-native AI coding agent built on *Bun.js* — fast startup, native TypeScript, built-in SQLite, no ceremony. It routes to *Anthropic, OpenAI, Google, Ollama, and Zen* and auto-detects your provider from env vars. No config file to write.…
What it does
In the maker’s words, at launch
I got tired of coding agents that feel like IDEs in disguise. Slow to start, full of chrome, opinionated about where you work. So I built one that doesn't get in the way. It's called *mini-coder*. The command is `mc`. Tagline: Small. Fast. Gets out of your way. Oh — and it mostly wrote itself (with some help from me). --- ## What it is mini-coder is a terminal-native AI coding agent built on *Bun.js* — fast startup, native TypeScript, built-in SQLite, no ceremony. It routes to *Anthropic, OpenAI, Google, Ollama, and Zen* and auto-detects your provider from env vars. No config file to write. No account to create. No telemetry. Session memory lives in local SQLite. Resume your last session with `mc -c`, or pick one with `mc -r <id>`. Your history stays on your machine. --- ## How it works The LLM gets a tight set of tools: `glob`, `grep`, `read`, `create`, `replace`, `insert`, `shell`, and `subagent`. That last one is the interesting bit — mini-coder can spawn parallel sub-agents for independent subtasks, up to 3 levels deep. It delegates, waits, synthesizes. It works the way you do. Inside the REPL, `!command` runs shell commands inline and `@file` references files with tab completion. Slash commands cover the essentials: `/model` to switch providers, `/plan` for read-only mode, `/ralph` for a fully autonomous loop, `/review`, `/undo`, `/new`, and `/help`. 16 ANSI colors only. It inherits your terminal theme. Always. --- ## The `.agents` folder This is the part is to help with community configurations. mini-coder follows the `.agents` convention that's emerging across the AI coding tool ecosystem — the same one used by Claude Code, Opencode, and others. Write your config once, and it works everywhere. (It supports the .claude conventions as well out of the box!) Here's what drops in there: - *`.agents/commands/.md`* — a Markdown file becomes a slash command - *`.agents/agents/.md`* — a Markdown file becomes a custom agent, callable with `@agent-name` - *`.agents/skills/<name>/SKILL.md`* — reusable skills you inject with `@skill-name` - *`.agents/hooks/post-<tool>`* — scripts that auto-run after any tool call (e.g., auto-format after every file write) - *`AGENTS.md`* — project context injected into every system prompt MCP is supported too — connect tools like Exa web search or the MMO Spacemolt all work. Wire them in via `/mcp`. The philosophy here is community over invention. Follow existing conventions. Don't make people learn a new system. --- ## Get it ```sh bun add -g mini-coder # or npm install -g mini-coder ``` GitHub: [https://github.com/sacenox/mini-coder](https://github.com/sacenox/mini-coder) --- The best tools disappear into your workflow. That's what I was going for. Here's what the early adopter had to say: > "sean this is fucking sick" — vpr99 That's good enough for me. Give it a spin. I would love some feedback, contributions, or just a star on. Github!

Huzzah – a novel approach to coding with AI17d ago · danielvaughn.dev · ▲384Hello everyone. I've been working on this experimental editor called Huzzah. I've been working almost exclusively with coding agents since January of this year, and over the past few months I began to feel utterly exhausted by them. They're great, but I'm finding it more and more tedious to write full sentences for every change I want. Not only that, but it seems there's a complexity limit for codebases - beyond a certain point the agent begins confusing itself. I'd like to go back to writing code, but I don't want to go all the way back to fully manual coding. So I've come up with this…

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.

Hey HN, Henry from Cactus here! We previously released Cactus Needle, a 14MB agentic LLM for tool call, device use, and structured extraction for phones, wearables, smart homes, small robots and microcontrollers. We got really great feedback here, and have now incorporated the suggestions to release Needle 2. The whole model is a single 14MB binary that runs a full session in 28MB of RAM; 45m parameters at 2bit compression. Needle hits 500 tokens/sec decode speed on a Raspberry Pi 5, sits between 400-1,500 tokens/sec on VR devices like Meta Quest 3S and Apple Vision Pro, and ranges…
