All my skills have disappeared an now i get errors

[nicksonnenberg]

I'm not sure what has happened but i had created like 12 really robust and complicated skills that now are no longer visible. The original skill files were my downloads that I uploaded to Claude. And then I might have renamed one of the files in my Download folder. I'm not sure if that could have caused an issue. But right now, I see a persistent "not found" error. And I'm not even able to upload a file into my Claude account. It shows a network error no matter what size of file I tried to upload (says "upload failed due to network issue, check your internet connection and try again"). And I have enabled in capabilities, the ability to do code and code execution and file. So I'm not sure what's going on. Something's clearly corrupt. And I'm wondering if I uninstall and reinstall is that the fix or do I lose all the skills that I've created if I do that? I don't think that the uninstall/reinstall is even going to fix it because from the web app I can't add skills now and all my skills are missing.

@rdu you having this issue too? Were you aggressively creating skills / MCP tools?

[rdu]

Yeah, I'm experiencing the exact same problem. All my skills suddenly vanished—even though I only ever used the standard built-in ones, nothing custom. Now I keep getting a "not found" error whenever I try to access the skills section.

When I check the browser’s network logs, the list-skills request returns this error:

{
    "type": "error",
    "error": {
        "type": "not_found_error",
        "message": "Not found",
        "details": {
            "error_visibility": "user_facing"
        }
    },
    "request_id": "req_...."
}

File uploads are also completely broken for me—every attempt fails with "Upload failed due to network issue," regardless of file size. My internet connection is stable, and I’ve double-checked that file and code execution capabilities are enabled in settings.

For what it’s worth, I’m on a Teams plan. Could this issue be specific to Teams accounts? It seems closely related to what’s described in #61.

Ya i can't upload files either and its very annoying I can't get ahold of anyone on support. I was giving a presentation at a conference to showcase the skills and mcp tools i built. I wasn't sure if the issue was my new MCP connection or maybe too many custom skills that were too big. But the issue started yesterday and its killing my workflow.

And when i go to the capabilities tab, it shows this error top right and it increments.

Morning,
First off, learn to use Claude CLI. Instruct Claude on rules. Instruct claude.md to build a rule that will write a skill when the LLM troubleshoots or Debugs for longer than 2-3 minutes. When the LLM runs into a situations where it is unable to quickly resolve an issue the LLM will apply the skills it previously wrote. Once you have burned a few million tokens the LLM will become more efficient. I've seen an 80-90% reduction in my token use. Mind you, I burnt 10 million tokens writing rules and skills. I use this logic in many other instances.

But no one on my team can now even upload a skill and I can’t event attach a small file to a regular chat. Is there a known bug/issue ?

It's the same case.

Seems similar as issue #61. We have a Teams account and experience the same issue.
