1. [I need to read the file first.] read_file({"path": "notes.md"}) -> shopping
TODO: pay rent
DONE: laundry
TODO: email sam
misc

2. [I need to find the TODO lines in the file.] extract_lines({"path": "notes.md", "match": "TODO", "dst": "todos.txt"}) -> 2 line(s) containing 'TODO' written to todos.txt
3. [I need to copy the file 'notes.md' to the sandbox directory to use it.] copy_file({"src": "notes.md", "dst": "notes.md.copy"}) -> copied notes.md -> notes.md.copy (59 bytes)
4. auto-finish: notes.md.copy was written; the goal is met
