# Task: three small scripts, planned with a task list

Create these files in the workspace root:

1. `greet.sh` — prints `Hello, NAME!` where NAME is the first argument, or
   `Hello, world!` when no argument is given.
2. `count.sh` — prints the number of lines in the file given as the first
   argument (just the number). Exits with status 2 and prints a usage line to
   stderr when no argument is given.
3. `SCRIPTS.md` — one short section per script explaining how to run it.

Both scripts must be executable POSIX shell scripts (`#!/bin/sh`).

Rules:
- Start by calling `todo_write` with one item per file, then keep the list
  up to date (mark each item done as you finish it). Every item must be done
  at the end.
- Nobody is available to answer questions in this run. If `ask_user` fails,
  pick a sensible default and continue.
- Test both scripts with `run_shell` before you finish.
