Skillsync lets you move 7 GB of Cursor sessions to Claude Code in minutes
Launch HN: Skillsync (YC W26) – AI chat sessions made portable across agents
Skillsync, a YC W26 startup, makes AI chat sessions portable across agents. Users can migrate gigabytes of Cursor history to Claude Code in minutes, switch between heavy models without losing context, and build decision traces to see every choice an agent made and why.
Skillsync is how I hold my agents accountable. I use it to build decision traces out of my sessions, so I can see every choice the agent made and why, not just the code it left behind.

I have made simple macos app to export my claude sessions to markdown(plus ordinal jsonl) and i just continuously sync it to dropbox.
i do the same for apple notes and imessage. so very portable

Love this. Easily the most annoying thing about modern Agent development across Claude, Codex, etc. One nit: You don't auto-discover "archived" chats from Codex. They have to be unarchived and the app restarted before being found.

this is awesome! i’ve been working on a tool for cross-harness integration tests - https://dynobox.xyz - and one of the hardest parts has been writing adapters for each harness since their transcript formats are all so different.
really excited to check out txcript… a shared translation layer could make my life sooo much easier!

Very cool! I created something similar (with the same name), but in 2 tools. One to share skills (skillsync) and another to share context (contextsync).
I like to create a design with one model, sync it to another and iterate on it, then potentially go to another to apply/implement.

This is awesome! You solve an immediate need of mine for:

Since I only support Pi natively, your solution will make it possible for codex/claude/etc. users to discover their conversations in my app. Will definitely include this as workaround for making codex, claude and other sessions available for discovery.
