macOS launchd agent to auto-prune stale Cursor log directories

README.md

cursor-logs-prune

A launchd agent that auto-prunes stale Cursor log directories on macOS.

Why

Cursor writes logs into ~/Library/Application Support/Cursor/logs/ — one date-stamped subdirectory per session — and never cleans them up. Left alone, the directory can accumulate tens or hundreds of GB and fill the disk.

The files hold no useful state; deleting them is safe (Cursor recreates the directory on next launch).

What it does

Runs daily at 3 AM and removes any top-level session directory older than 7 days:

find "$HOME/Library/Application Support/Cursor/logs" \
    -mindepth 1 -maxdepth 1 -type d -mtime +7 \
    -exec rm -rf {} +

Install

cp com.user.cursor-logs-prune.plist ~/Library/LaunchAgents/
launchctl load ~/Library/LaunchAgents/com.user.cursor-logs-prune.plist

Verify

launchctl list | grep cursor-logs-prune

Dry run:

find "$HOME/Library/Application Support/Cursor/logs" \
    -mindepth 1 -maxdepth 1 -type d -mtime +7

Run output: /tmp/cursor-logs-prune.log.

Disable

launchctl unload ~/Library/LaunchAgents/com.user.cursor-logs-prune.plist
