clauhist: browse full Claude Code history and resume sessions across projects

lef237 — Sat, 28 Mar 2026 04:43:38 +0000

Claude Code can already help you resume work from a project if you move into that working directory and use /resume there.

The limitation is that this is tied to the current working directory. If you want to look back across all of your past work, including sessions from other repositories and directories, that gets awkward.

clauhist is a small CLI tool for that case. It shows your Claude Code history in fzf, lets you browse sessions across working directories, and resume one from the list.

What it shows

Sessions are sorted by recent activity. Each row includes:

the last activity time
the project path
whether the path still exists
a preview of the first message
the message count

There is also a preview pane with the session ID, timestamps, and message list. Once you find the one you want, press Enter.

How it works

clauhist reads ~/.claude/history.jsonl, groups entries by session, and passes the result to fzf.

After you select a session, it runs:

claude --resume <session-id>

It does not keep its own database or add another history layer. It is just a thin local browser over Claude Code's existing history file.

Installation

cargo install clauhist

Or install from source:

git clone https://github.com/lef237/clauhist.git
cd clauhist
cargo install --path .

You also need fzf and Claude Code installed.

Usage

clauhist

Main controls:

Enter: resume the selected session
type: filter the list
Ctrl-/: toggle preview
Ctrl-C: exit

It is displayed on the terminal like this:

╭───────────────────────────────────────────────────────────────────────────────────────╮
│ Claude Code History Browser  [Enter: resume  Ctrl-/: toggle preview  Ctrl-C: cancel]  │
├───────────────────────────────────────────────────────────────────────────────────────┤
│ Search:                                                                               │

╰───────────────────────────────────────────────────────────────────────────────────────╯

✓ means the project directory still exists. ✗ means it was moved or deleted. You can still resume the session, but cd into the original directory may fail.

Shell integration

If you add this to your shell config:

eval "$(clauhist init zsh)"

then clauhist will now change to the project directory within your current shell before launching Claude Code.

This allows you to immediately return to your original directory with cd -.

Without this, clauhist uses a subshell for the directory change, so exit to return to your original shell.

Local-only

clauhist only reads ~/.claude/history.jsonl and launches claude --resume. It does not send your history anywhere.

That is the whole tool: a simple way to browse past Claude Code sessions across projects and reopen one without moving directory by directory.

(Example output — actual appearance depends on your terminal and fzf version)

Claude Code can already resume work from the current project directory. clauhist solves a different problem: browsing the full history across all of your working directories from one place.

Select a session and press Enter — clauhist opens claude --resume in the project directory. When you exit Claude, you return to your original shell.

Why clauhist exists

If you cd into a project and use Claude Code's /resume there, you can inspect…

One-Time Editor, an editor for drafts before sending

lef237 — Mon, 09 Mar 2026 13:16:35 +0000

I've created an app called "One-Time Editor".

The image above shows dark mode. Here's what it looks like in light mode.

What kind of app is it, you ask? It's a text editor that can be used for drafting messages before sending them in a chat.

By using this app, you can avoid the worry of accidentally sending a message prematurely by hitting Enter.

To quickly understand how it works, I recommend watching the video, which I've attached below.

https://youtu.be/qwj9fr77vQg

How to Install

For macOS, use Homebrew. You can start using it right away by typing the following commands in your terminal.

brew tap lef237/tap
brew install --cask one-time-editor

Since it's an Electron-based app, it's also cross-platform compatible.

Windows and Linux users can install the pre-built app from here.

https://github.com/lef237/one-time-editor/releases

Windows users should select the .exe file, and Linux users should select the AppImage to install it. ¹

Features

The main highlight is that you can toggle (show/hide) the window using a keyboard shortcut.

What's more, it automatically copies the content you've entered as soon as you toggle it, allowing for instant pasting.

Open One-Time Editor with a keyboard shortcut.
Type the content you want to send.
Close it with the keyboard shortcut.
- The content will be automatically copied.
- On macOS, focus will automatically return to the window you were previously using.
Paste and then send.

It also supports switching between light and dark modes. I think the design is also stylish.

Of course, you can also customize the keyboard shortcut! The default is Ctrl+J, but feel free to assign any shortcut you like.

Why I Made It

Many people have probably experienced indecision about whether to use Enter, Shift+Enter, or Ctrl+Enter to send a chat message.

And then, accidentally sending a message in the middle of writing...

Using some kind of editor for drafting isn't bad, but it can be a bit cumbersome to constantly be asked to create a new file or to manage windows.

This app is designed for throwaway writing, and it allows for displaying/hiding the window and copying content with a single shortcut, making it quite fast.

Challenges During Development

There were several challenges.

However, the most difficult problem was dealing with code signing and notarization.

When you create an app with Electron, it works fine on your local machine, but if you upload it to the internet and download it, the app becomes corrupted.

You might have seen this warning when downloading things like Docker:

Therefore, you need to use the xattr command.

Fix macOS app is damaged and can't be opened" Error - Complete Guide - osxhub

osxhub.com

This means you need to run the command xattr -rc "/Applications/hoge.app" after installation, which is a bit troublesome.

When I looked into simplifying this, I realized that using postflight could automate this process if installed via homebrew-tap.

Install

macOS (Homebrew)

brew tap lef237/tap
brew install --cask one-time-editor

Manual download

Pre-built binaries for macOS, Windows, and Linux are available on the Releases page.

If you download manually on macOS, the app is not signed with an Apple Developer certificate, so macOS may show a warning. To allow it, run:

xattr -cr "/Applications/One-Time Editor.app"

How it works

Press Ctrl+J to summon the editor
Type your text
Press the shortcut again — the window disappears and your text is copied to clipboard
Paste wherever you need it

That's it. No save dialog, no file management, no friction.

The shortcut is…
