Shella Logs

View daemon and plugin logs from ~/.local/state/shella/dev.log.

Arguments

• $ARGUMENTS may contain:
  • A plugin name to filter by (e.g., "agent", "terminal")
  • A number of lines to show (default: 50)
  • "all" to show more lines
  • "errors" or "error" to filter to errors/warnings only

Log File Location

~/.local/state/shella/dev.log

Each line is JSON with fields: time, level, prefix, msg, and optional data fields.

Commands

Recent logs (last 50 lines):

tail -50 ~/.local/state/shella/dev.log

Filter by plugin (prefix field contains plugin name):

grep '"prefix":"agent' ~/.local/state/shella/dev.log | tail -50

Errors only:

grep '"level":"error"' ~/.local/state/shella/dev.log | tail -50

Parse and format for readability - extract time, prefix, level, msg:

tail -50 ~/.local/state/shella/dev.log | while read line; do
  echo "$line" | python3 -c "import sys,json; d=json.loads(sys.stdin.read()); print(f'{d.get(\"prefix\",\"daemon\"):20} {d.get(\"level\",\"info\"):5} {d.get(\"msg\",\"\")}')" 2>/dev/null || echo "$line"
done

Output

Present logs in a readable format. For JSON lines, extract the key fields (timestamp, prefix, level, message). Highlight errors in your response.

If the log file doesn't exist, tell the user the daemon hasn't been run yet or logs are empty.
