The typo is on line 2 of notes.txt itself; the workspace contains no other file. Inspect it with the bash tool: run exactly `cat notes.txt` (relative path, no other command). Then present a one-step plan titled '# Fix the greeting typo' via exit_plan_mode: the single step is editing line 2 of notes.txt to say hello world. Do not edit anything before the review approves. After it approves, apply exactly that one edit to notes.txt with the edit tool and stop — no other commands, do not look for any other file.

The file has two lines:

- Line 2: `- the greeting message still says "helo wrld"`

The user says line 2 has a typo and should say "hello world". So I need to replace line 2 with "hello world".

Let me present the plan.


# Fix the greeting typo

## Single step
1. **Edit line 2 of `notes.txt`** — Replace the content of line 2 (`- the greeting message still says "helo wrld"`) with `hello world`.


Plan approved — plan mode exited; carry out the plan starting with your next step.
