The article discusses OpenAI's Codex, a cutting-edge AI system that can translate natural language into code, allowing users to write software more efficiently. It highlights Codex's potential to revolutionize programming and empower a wider range of people to create technology.

I built a small macOS menu bar app that lets you check your Claude Code subscription usage with a single click, without touching your terminal.

## The problem

If you use Claude Code heavily, you probably run multiple sessions across multiple terminal windows. When you want to check how much of your usage limit you've burned through, your only option is to type `/usage` inside a Claude Code session. That means either:

1. *Interrupting a running agent* mid-task to type a command, or 2. *Opening a new terminal and starting a new session* just to check a number

Both are disruptive. You lose flow, and the agent loses context.

## Why not just call the usage API?

A lot of community tools solve this by grabbing the OAuth token that Claude Code stores in the macOS Keychain and calling Anthropic's usage API directly. This works, but it has a real UX and security cost: *macOS will prompt you every time a third-party app tries to read that Keychain item.* You get a system dialog asking whether to allow access, sometimes repeatedly. It's not a smooth experience, and handing your OAuth token to another process is a legitimate security concern.

## How CC Usage Bar works differently

CC Usage Bar takes a simpler, zero-trust approach. It doesn't touch your Keychain, doesn't make any network calls itself, and doesn't parse or store any credentials. Instead, when you click the menu bar icon, it:

1. Spawns a real Claude Code session in a pseudo-terminal (PTY) 2. Sends the `/usage` command 3. Captures and renders the output with full ANSI color fidelity 4. Terminates the session immediately

It literally runs `claude` the same way you would, just in a hidden terminal. The data comes straight from Claude Code itself, so it's always accurate and reflects the latest state. No reverse engineering, no API scraping, no hacks.

## What it looks like

A single icon in your menu bar. Left-click to open a popover showing your current usage. Click outside to dismiss. That's it.

- Native Swift/SwiftUI app, runs as a lightweight menu bar agent (no Dock icon) - macOS 14 Sonoma or later - Requires Claude Code already installed and on your PATH

Happy to hear feedback or ideas. If you've been annoyed by the same workflow interruption, give it a try.

Nintendo filed a DMCA takedown request to GitHub, seeking the removal of code that allegedly infringes on their copyrights. The code appears to be related to Nintendo's gaming systems and was hosted on GitHub repositories.

OpenAI released Symphony — a project-level orchestrator that watches your Linear board, spawns isolated coding agents per task, and lands PRs automatically. Engineers manage work at a higher level instead of supervising agents one by one.

They shipped an Elixir reference implementation and explicitly said "implement it in any language you want." So I built the Go version — with multi-agent team coordination on top, so multiple agents can collaborate across different parts of a codebase in parallel. Currently supports openai/codex and opencode as agent runtimes.

Hey everyone,

I'm the original co-creator of RedwoodJS. (The framework that myself and Tom Preston-Werner, Rob Cameron and David Price built during Covid.)

I had tried to build a developer tool startup (Snaplet), and failed. I rejoined the efforts to add RSC to Redwood, but I realized that we needed a much simpler framework that was closely tied to a platform (We chose Cloudflare).

We started building RedwoodSDK a year ago and this is the result. An insanely simple stack. I am incredibly proud of this work, please star our repo and let me know if there's anything that doesn't resonate with you.

Hi HN,

I built SlideHTML as a small experiment after noticing that LLMs are surprisingly good at writing HTML layouts.

Instead of building another slide editor, I tried the opposite approach: let AI generate slides directly as HTML.

SlideHTML is a small Electron app that simply watches a folder and renders each HTML file as a slide.

My workflow is basically:

1. Open a folder 2. Ask Claude Code or Gemini CLI to generate slides 3. SlideHTML renders them live 4. Hit present

No editor, no proprietary format — just HTML.

The whole thing was built in about 3 hours as an experiment.

Curious what HN thinks about HTML as a slide format in the AI era.

I was paying $100/mo for Claude Code Pro and had no idea where it was going. I'd hit the 5-hour rate limit constantly, but couldn't tell which sessions were burning through my allocation or whether Opus was worth the premium over Sonnet for my workflows. So I built a tool to find out.

BurnRate is a local CLI that parses your AI coding tool session data and gives you a full cost analytics dashboard. It tracks Claude Code, Cursor IDE, and OpenAI Codex in one place.

Everything runs 100% on your machine. Your session data, token counts, costs, prompts — none of it leaves your computer. No API key to paste, no telemetry. It reads the local session files your tools already generate and does the math.

Out of the box you get: multi-provider cost tracking, 10 different analytics views (daily trends, per-session breakdown, model usage split, token efficiency), an optimization engine with 23 rules that suggests concrete config changes to reduce spend, usage limit monitoring so you know when you're approaching rate limits, side-by-side provider comparison, and budget alerts when you're on track to blow past a monthly cap.

For managers, there's a team dashboard where devs can optionally push anonymized usage snapshots to a shared view. Useful for understanding team-wide AI tool costs and figuring out which plans actually make sense. Free tier available, Pro is $9/mo, Team is $29/mo.Happy to answer any questions. Feedback welcome.
