v0.46.1

charmbracelet/crushv0.46.1Feb 27, 2026by github-actions[bot]

AI Summary

This release fixes performance issues with file tools (view and edit) that were slow due to LSP server notifications. A 300ms timeout was added so operations proceed even if LSP servers are slow, and the find_references functionality was also fixed.

Key Highlights

Fixed slow file tool performance - view and edit were slow because they waited for LSP responses
Added 300ms timeout for LSP diagnostics so operations proceed even if LSP is slow
Fixed find_references functionality to properly query LSPs for references
Performance optimizations: avoid file watching when reading, shared timeout for parallel diagnostics, avoid scanning entire file to count lines
Fixed view tool paging and UTF-8 validity check edge cases

New Features

300ms timeout for LSP diagnostics to prevent slow operations
find_references now properly queries LSPs for type/function references

Full Release Notes

# File tools performance fixed ✅ 

A few of you told us that some tools call like `view` and `edit` were sometimes taking a few seconds to complete, making your sessions slow to proceed. Well, that happened because Crush notifies LSP servers about the files you're viewing or touching, and waits for a response. Some LSPs are slow, and it things took some time to happen.

In this release we not only made a good number of fixes to file tools + LSPs, but we also added a 300ms timeout so if something got stuck Crush will proceed anyway.

The `find_references` also got fixes. It allows the model to query for your LSPs to find refences for a given type/function/etc.

Special thanks to our favorite contributors @huaiyuWangh and @taigrr to helping and testing these improvements! ✨ 

Enjoy your weekend!

<summary>Verifying the artifacts</summary>

First, download the [`checksums.txt` file](https://github.com/charmbracelet/crush/releases/download/v0.46.1/checksums.txt) and the [`checksums.txt.sigstore.json` file](https://github.com/charmbracelet/crush/releases/download/v0.46.1/checksums.txt.sigstore.json) files, for example, with `wget`:

```bash
wget 'https://github.com/charmbracelet/crush/releases/download/v0.46.1/checksums.txt'
wget 'https://github.com/charmbracelet/crush/releases/download/v0.46.1/checksums.txt.sigstore.json'
```

Then, verify it using [`cosign`](https://github.com/sigstore/cosign):

```bash
cosign verify-blob \
  --certificate-identity 'https://github.com/charmbracelet/meta/.github/workflows/goreleaser.yml@refs/heads/main' \
  --certificate-oidc-issuer 'https://token.actions.githubusercontent.com' \
  --bundle 'checksums.txt.sigstore.json' \
  ./checksums.txt
```

If the output is `Verified OK`, you can safely use it to verify the checksums of other artifacts you downloaded from the release using `sha256sum`:

```bash
sha256sum --ignore-missing -c checksums.txt
```

Done! You artifacts are now verified!
