CodeCortex – Persistent repository knowledge graph for AI coding agents
I’ve started an open-source experiment called CodeCortex.
The idea is simple:
AI coding tools repeatedly re-learn the same repository structure every session.
This wastes tokens and often misses architectural dependencies.
CodeCortex explores a different approach: build a persistent knowledge graph of the repository that evolves with the codebase.
Instead of rescanning the repo, AI agents query the graph.
Still early, but the repo is now public.
Curious to hear thoughts from people building with AI coding tools.

Show HN: MicroMoment Apple Watch micro-resets for focus, posture, and wellbeing
Hi HN!
I built MicroMoment App, an Apple Watch app designed for 30–90 second micro-resets during the day.
The idea came from noticing how hard it is to maintain focus and good posture while working at a computer for long periods. Instead of long breaks or complicated routines, MicroMoment lets you do tiny actions that reset your mind and body without interrupting your workflow.
With one tap on your watch, it starts a short micro-action like:
a quick stretch
mindful breathing
posture correction
a small energy boost exercise
Everything is designed to be fast, glanceable, and doable in under 2 minutes.
Key features: - Instant Reset Button – tap once to start a random micro-action - Timer + haptic guidance – subtle vibrations guide you through the exercise - Daily streaks – track consistency - Personalized suggestions based on your usage - Surprise mode with occasional fun mini-actions - Challenges & achievements to keep things interesting - Watch face complication showing your next micro-moment or streak
The goal is simple: help people feel better throughout the workday with minimal friction.
I’d love feedback from the HN community — especially on:
- whether micro-actions like this are actually useful - features you'd want in a watch-first productivity/wellbeing app - ideas for new micro-actions
Happy to answer any questions!
Show HN: Pitwall – Live F1 Stats in Your macOS Menu Bar
I built this because I got tired of tabbing away during F1 practice sessions to check live timing. The idea was simple: keep race stats accessible in the menu bar without eating screen real estate. What it does:
Live driver positions & session timing Real-time telemetry (speeds, gaps, tire info) PitStop F1 API integration Zero full-window footprint
Current status: Live on the Mac App Store. It works, but I'm actively iterating. The biggest challenge so far has been getting reliable real-time data without hammering the API. I'm caching aggressively and considering WebSocket fallbacks.
What I'm stuck on:
Performance with rapid session updates Whether the feature set justifies the menu bar UX or if users expect more Data accuracy during race weekends (some API endpoints are inconsistent)
Shipping small indie projects is harder than I thought, mostly in the "people actually knowing it exists" department. Any feedback on the concept, execution, or what's obviously missing would be genuinely helpful. Open to suggestions.
