--- user (14:58:04) ---
Fix the bug in parser.py

--- assistant (14:58:06) ---

  > Read scripts/parser.py
    [2847 chars, truncated]
    def parse(input):
        tokens = input.split()
        ...

  > Edit scripts/parser.py
    old: if t.startswith("--"):
    new: if t.startswith("--") or t.startswith("-"):

Fixed the parser to handle single-dash flags.

--- user (14:58:12) ---
  < tool_result (Read): [ok]
  < tool_result (Edit): [ok]

--- assistant (14:58:15) ---
Done. The parser now handles both --flag and -f syntax.
