I haven't written a blog post in 11 years, but the recent experience of building a complete macOS app with AI has me so optimistic about the future of software development that I had to share more about the process.

You can now directly talk to @sentry in slack like Linear or any other agent. Give it a shot and let us know what you think

I'm excited to finally get this into the hands of customers - we're using this internally on a regular basis and it's clear that it solves real problems. Querying and correlating telemetry to debug a problem is tedious, and Seer Agent can do it faster than any engineer can.

Let it be known: Seer Agent (coming soon) nailed the actual root cause, Devin and Cursor only hit the surface level. Same prompt.

We're running a new experiment at Sentry that will identify the root cause of issues and create a meta-group of these issues together. This is a true behavioral root cause rather than a traditional source-root. If you have a noisy issue stream that this kind of thing sounds great, you're willing to give helpful feedback, @cvxluo can opt you into the beta!

GHFS is useful in combination with Claude's /add-dir command. /add-dir ~/ghfs// to add any of your GitHub repos to your workspace without having to clone or manage a working copy.

Cursor Automations now support event-based triggers for Sentry. Set up agents that automatically respond to new issues, investigate root causes, open PRs with fixes, and post summaries to Slack.

@aussetg It’s a lazy clone. Serves requests (directory listings and file reads) via the GitHub API directly and then triggers an asynchronous clone only upon the initial file read in a given repo.

@indragie > Read only > periodic refresh So it’s `git clone` …?

I built GHFS: a virtual read-only filesystem for macOS that mounts your GitHub repositories locally. You can point agents at a mount directory where all repos are available and are automatically cloned on-demand.

API available on 15.4+ but I've only tested this on Tahoe so that's what the minimum deployment target is set to Lots of thoughts that I'll put into a longer post at some point but: - FSKit as an API generally works as advertised - Enabling FSKit extensions is a huge pain. There's no programmatic way to enable it (even by presenting a permissions dialog). User has to do it manually via Settings - It throws cryptic errors when a stale version of the FSKit extension exists (like when there's multiple copies of the app). I had Claude debug and built a script that handles most of this cleanup for me: #L184-L261" target="_blank" rel="nofollow noopener">github.com/indragiek/GHFS… - My starting point was getting Claude to distill all of the FSKit docs + the single sample code reference from Apple (developer.apple.com/documentation/…) into a reference doc that it used to then implement the project. I've checked this into the repo as FSKIT.md.

@indragie TIL: FSKit API fixes the macFUSE issues. I've seen a bunch of people have been doing similar to this for different use-cases - but using NFS on Mac instead. Any gotchas? How did you get started? Tahoe only?

@oops4041555 @ImLunaHey FSKit is available on macOS 15.4+ but I've only tested this on 26. You could try building from source and changing the deployment target to 15 to see what happens.

@indragie @ImLunaHey can i run this on not-tahoe?

@HotAisle Multi-account support should be easy to add. Thanks for the feedback.

@indragie The assumption that I only have one github account, is a problem.

@_heyglassy Early Tahoe releases were rough but I’m finding 26.4 to be pretty solid. They’ve cleaned up a lot of the Liquid Glass rough edges too

Things like this are the only reason it's worth it to upgrade to MacOS Tahoe.

The app is completely self-contained. It doesn't require macFUSE because it uses Apple's new FSKit API for building user space file system extensions. It also uses libgit2 running in-process instead of forking out to gh or git for git operations.

@dillon_mulroy @indragie promised something shortly 😅 cc @kdaigle

GitHub fs is still a useful idea!

@utpalnadiger Congrats on launching!

the goal isn't just to build primitives, but to build clever abstractions to make it easy for folks to ship agents. we shipped agents.opencomputer.dev, go give it a shot!

@daniel_leach_ @AnthropicAI Cloud

@indragie @AnthropicAI Cloud or local?

We partnered with @AnthropicAI to make it one click to go from Sentry’s root cause analysis to a code change generated by Claude!

@sentry now takes you from Seer's root-cause analysis to a Claude-powered agent that writes the fix and opens a PR. They built the integration on Managed Agents in weeks: claude.com/customers/sent…
