Show HN: Skillsync – Coding agent memory but it's just search I built a claude mod that searches every session (across harnesses) on each prompt. On every prompt, it runs a series of decision models to pick the right sessions + messages and adds anything relevant to the context. Requires no indexing or setup and works out of the box Demo: https://youtu.be/o5vEf8tgus4 https://skillsync.com October 21, 2026 at 12:04AM

Show HN: Agent Archive – Session Handoffs and Backups for Claude Code and Codex https://ift.tt/DFRfCZ0

Show HN: Agent Archive – Session Handoffs and Backups for Claude Code and Codex I often switch between Claude Code and Codex throughout the week, and between my laptop and an older machine I leave running at home. I built agent-archive to make it easier to pick up where I left off, especially when i hit usage limits. It lets you (or a coding agent) find past coding sessions and hand their conversation context to another agent. You can try local handoffs without setup, or connect your own S3/R2 bucket for automatic archiving and access from other machines. It also tracks usage across agents and gives you a full archive of your session transcripts across agents, which I've found useful to iterating and improving my AGENTS.md and lint rules. https://ift.tt/xIyuDJW October 20, 2026 at 10:54PM

Show HN: I wrote an email app that accepts only one sender per inbox https://ift.tt/m1nLdrz

Show HN: I wrote an email app that accepts only one sender per inbox Infinite inboxes, including prefixes where you don't have to create inboxes before you use them -- they self create when you add a suffix. Three types of inboxes: - One sender. Locks to the first domain to send email (except gmail, outlook, etc where it locks to an email account for obivous reasons. It bounces everyone else. - Temporary. Lasts for a while (24h, 7days, etc) then bounces. Received messages stay or go as per your choice. - Prefix. The most powerful. Declare a prefix like "service" and then invent any suffix, like "service-netflix" or "service$bank" and it creates a new one-sender inbox locked to whoever wrote first. Bring you own domain. Bring your own AI (MCP server ready). Forwarding. Please help me test it. https://clova.email/ October 15, 2026 at 12:00AM

Show HN: XY Music Notation https://ift.tt/Tgh6KID

Show HN: XY Music Notation I've been playing around with a new kind of isomorphic music keyboard that uses a base-12 notation, and wanted some sheet music to learn some new music for it. The idea is to represent each note in 12-TET as a number, so N ∈ (0,1,2,3,4,5,6,7,8,9,X,Y). I used codex to build a music score rendering backend based on MuseScore with custom note heads that display the pitch class of each note. I've found it pretty helpful for learning how to play my own instrument, so wanted to share in case anyone else was interested. https://music.xy.dev/ October 14, 2026 at 12:43AM
