claude-chat-cleaner

A Claude Code plugin and CLI tool to clean up unnecessary conversation history files.

Claude Code stores conversations as .jsonl files in ~/.claude/projects/. Over time, these accumulate empty, failed, interrupted, and trivial sessions that waste disk space. This tool analyzes and cleans them up.

What it does

• Scans all Claude Code project directories for .jsonl chat files
• Classifies each chat as rubbish or useful based on content analysis
• Shows a per-project breakdown with content previews before deleting anything
• Safe by default — always dry-run first, delete only when you confirm

Classification rules

A chat is classified as rubbish if ANY of these are true:

Rule	Example
No user or assistant messages	Empty sessions, metadata-only files
Single trivial message (< 50 chars)	Typos, accidental invocations like :q
First messages are all init/error/interrupted	Failed sessions, API errors, user interrupts

Everything else is classified as keep.

Installation

As a Claude Code plugin (recommended)

Plugins get automatic updates when new versions are released.

Option A — from the marketplace:

/plugin marketplace add jainsvaibhav/claude-chat-cleaner
/plugin install chat-cleaner@claude-chat-cleaner

Option B — from local directory:

git clone https://github.com/jainsvaibhav/claude-chat-cleaner.git
claude --plugin-dir ./claude-chat-cleaner

Then in Claude Code:

/chat-cleaner:chat-cleanup

As a standalone skill

If you prefer short skill names (/chat-cleanup instead of /chat-cleaner:chat-cleanup):

git clone https://github.com/jainsvaibhav/claude-chat-cleaner.git
cd claude-chat-cleaner
./install.sh

Then in Claude Code:

/chat-cleanup

Standalone CLI only

If you just want the command-line tool without Claude Code integration:

curl -o claude-chat-cleaner https://raw.githubusercontent.com/jainsvaibhav/claude-chat-cleaner/main/claude-chat-cleaner
chmod +x claude-chat-cleaner
sudo mv claude-chat-cleaner /usr/local/bin/

Remote machines

scp claude-chat-cleaner remote-host:~/
ssh remote-host "python3 ~/claude-chat-cleaner --analyze"
ssh remote-host "python3 ~/claude-chat-cleaner --delete"

Usage

CLI

# Dry-run — see what would be deleted (default)
claude-chat-cleaner --analyze

# Actually delete rubbish files
claude-chat-cleaner --delete

# Filter to a specific project
claude-chat-cleaner --analyze --project my-project

# JSON output for scripting
claude-chat-cleaner --analyze --json

# Custom .claude directory
claude-chat-cleaner --analyze --claude-dir /path/to/.claude

Claude Code (plugin)

Claude will:

1. Run --analyze to scan all projects
2. Present a summary table of rubbish vs. useful chats
3. Ask for your confirmation before deleting
