Some simple ideas that can be done in minutes with any chat AI

simple progress and deliverables are important for programming/ai beginners.

1 expand script
curl supports [1-99] like number enumeration, and bash supports {a,b,c,d} list expand.
write a python script that expand argv[1]. (seq -f "%g" number also works though)

2 pastebin
note that in python 3.14, there is no more multipart parser to accept file upload easily.
save the file/text under upload-timestamp-randomnumber.txt
and use Content-Type application/octet-stream for any file/text display.

3 line joiner or slot joiner(if all keyword appeared, display in order)
script filename a,b,c,d
works like grep but if the first keyword appears(or EOF), it flush the collected lines and output in input keyword order and saves itself. lines without match are discarded.

input:
a0
e5
a1
c2
b3
d4

output:
a0
a1b3c2d4

4 detect screen defects with single color fullscreen (python tk)
use red,green,blue,white,black colors, use space/mouse button for next color, or esc/any action after final color to exit

5 rename files based on header

def detect_extension(header):
    if len(header) >= 12 and header[4:12] == b'ftypisom':
        return '.mp4'
    elif header.startswith(b'\x30\x26\xb2\x75'):
        return '.wmv'
    return None

if file header match some known filetype, generate command / do the rename.
you can also ask AI to do basename NFC normalization as well (cant rename folder).
