In `@libs/terminal_ui.py.orig`:
- Around line 119-124: select_model currently assumes list_available_models()
returns a non-empty list and will IndexError on models[0]; modify select_model
to handle an empty models list by checking "models" first and returning None (or
raising a clear ValueError) instead of indexing it. Locate select_model and use
list_available_models() and get_default_model_name() to decide flow; if models
is empty, return None (or raise with a descriptive message) otherwise proceed
with computing default_model and calling _select_option('Model', models,
default_model, ...). Ensure callers that expect a model handle the
None/exception accordingly.
- Around line 38-46: In both input branches that read raw keystrokes (the POSIX
branch using tty.setraw(fd) and the Windows branch that reads single bytes),
handle Ctrl-C ('\x03') explicitly by mapping it to the cancel/escape path used
by _select_option; update the POSIX block (where key is read and arrow-map is
applied) to check if key == '\x03' and return 'escape' (or the existing cancel
token), and make the same explicit check in the Windows reading code so '\x03'
does not fall through as a no-op but instead triggers the existing cancel/escape
behavior referenced by _select_option.
- Around line 155-158: TerminalUI currently lets a KeyboardInterrupt from
TerminalUI._select_option propagate (on Esc/Ctrl-C) because TerminalUI.launch
and prepare_args do not catch it; update the call sites (e.g., wrap
TerminalUI.launch and prepare_args invocations) to catch KeyboardInterrupt and
exit cleanly (call sys.exit(0) or print a short user-friendly message) instead
of letting it propagate to interpreter.py; alternatively add a top-level
try/except KeyboardInterrupt in __main__ or in interpreter.py around the main
dispatch so any KeyboardInterrupt raised by TerminalUI._select_option is handled
gracefully and no raw traceback is printed.
- Around line 40-43: TerminalUI._read_key currently calls sys.stdin.read(2) when
it sees '\x1b', which blocks for two bytes and causes a lone Escape to hang;
change this to perform a non-blocking/short-timeout check (e.g., use
select.select on sys.stdin with a small timeout) to see if additional bytes are
immediately available and only then call sys.stdin.read(2) and map sequences
(mapping dict already present) to 'up'/'down'/'left'/'right'; if no bytes are
available within the timeout, immediately return 'escape' so the cancel path in
_select_option can run.
- Line 1: Delete the tracked artifact libs/terminal_ui.py.orig and add a *.orig
rule to .gitignore; then harden TUI: update _read_key to avoid blocking after a
lone '\x1b' by using a non-blocking/read-with-timeout approach (e.g., check
available input with select or termios/tty read-with-timeout) so a single Escape
returns immediately instead of doing sys.stdin.read(2). In _select_option and
select_model, guard against empty inputs by returning None or raising a
controlled exception when options/models is empty (do not index options[0] or
models[0] unguarded). Finally, in interpreter.py catch KeyboardInterrupt (and
any propagated cancellation exception from _select_option) and convert it into
clean cancellation handling (return or propagate a cancellation result instead
of letting the process terminate).

Ctrl-C is a keyboard trap in raw POSIX mode.
tty.setraw(fd) disables ISIG, so Ctrl-C arrives as the literal byte \x03 instead of raising KeyboardInterrupt. In _select_option, \x03 falls through to the single-char prefix branch (Line 104) and does nothing, so the user cannot abort. Map \x03 to the cancel path (this is the fix the PR applies in libs/terminal_ui.py).
🐛 Proposed fix
key = sys.stdin.read(1)
+ if key == '\x03':
+ return 'escape'
if key == '\x1b':
next_chars = sys.stdin.read(2)The Windows branch (Lines 19-30) has the same gap — \x03 should also map to 'escape' there.

In `@libs/terminal_ui.py.orig` around lines 38 - 46, In both input branches that
read raw keystrokes (the POSIX branch using tty.setraw(fd) and the Windows
branch that reads single bytes), handle Ctrl-C ('\x03') explicitly by mapping it
to the cancel/escape path used by _select_option; update the POSIX block (where
key is read and arrow-map is applied) to check if key == '\x03' and return
'escape' (or the existing cancel token), and make the same explicit check in the
Windows reading code so '\x03' does not fall through as a no-op but instead
triggers the existing cancel/escape behavior referenced by _select_option.

How to distinguish a lone Escape key from an arrow-key escape sequence when reading stdin in POSIX raw mode in Python
💡 Result:
To distinguish a lone Escape key (ESC) from an arrow-key escape sequence (which starts with ESC) in POSIX raw mode, you must implement a non-blocking read with a short timeout after receiving the ESC character [1][2]. Because both events begin with the byte 0x1B, the system cannot determine if the user pressed the Escape key or the beginning of a sequence without waiting to see if further bytes arrive [3][2]. The standard approach to handle this is: 1. Read a single byte from stdin. If it is 0x1B (ESC), enter a "waiting" state [1][2]. 2. Use a function like select.select to check if more data is immediately available on stdin, with a short timeout (typically 50ms to 100ms) [4][1][2][5]. 3. If additional data arrives within the timeout period, it is part of an escape sequence; continue reading to collect the full sequence (e.g., [ followed by A, B, C, or D for arrow keys) [6][2][5]. 4. If the timeout expires and no further data has arrived, interpret the initial 0x1B as a lone Escape key press [2][7]. This logic mirrors how terminal libraries like ncurses or tools like Vim handle input ambiguity [1][3][7]. Attempting to perform a simple blocking read for the subsequent bytes will cause the application to hang if the user simply pressed the Escape key, as the terminal will wait indefinitely for more input that will not arrive [2]. For robust implementation in Python, use the termios and tty modules to configure the terminal in raw mode, ensuring that the application receives every keystroke immediately without buffering [8][5][9][10]. Always use a try...finally block to restore the terminal to its original settings after your program finishes [4][9][10].

Lone Escape press blocks cancel in raw-mode input
TerminalUI._read_key treats \x1b as the start of an arrow/CIS sequence, then calls sys.stdin.read(2); this blocks until two more bytes arrive, so a standalone Escape never reaches _select_option’s key == 'escape' cancel path and the UI can hang. Use a non-blocking/short-timeout read (e.g., select.select) to detect whether the following bytes are immediately available and only then map to arrow keys; otherwise return 'escape'.

currently calls sys.stdin.read(2) when it sees '\x1b', which blocks for two
bytes and causes a lone Escape to hang; change this to perform a
non-blocking/short-timeout check (e.g., use select.select on sys.stdin with a
small timeout) to see if additional bytes are immediately available and only
then call sys.stdin.read(2) and map sequences (mapping dict already present) to
'up'/'down'/'left'/'right'; if no bytes are available within the timeout,
immediately return 'escape' so the cancel path in _select_option can run.

models[0] can raise IndexError on empty model list.
If list_available_models() returns an empty list (no configured providers), Line 123 indexes into it and crashes. Guard the empty case.

In `@libs/terminal_ui.py.orig` around lines 119 - 124, select_model currently
assumes list_available_models() returns a non-empty list and will IndexError on
models[0]; modify select_model to handle an empty models list by checking
"models" first and returning None (or raising a clear ValueError) instead of
indexing it. Locate select_model and use list_available_models() and
get_default_model_name() to decide flow; if models is empty, return None (or
raise with a descriptive message) otherwise proceed with computing default_model
and calling _select_option('Model', models, default_model, ...). Ensure callers
that expect a model handle the None/exception accordingly.

Handle Ctrl-C/Esc in the TUI without leaking a traceback
TerminalUI._select_option()raisesKeyboardInterruptonescape, andTerminalUI.launch()/prepare_args()don’t catch it.interpreter.pyonly catchesSystemExitandException, soKeyboardInterruptescapes to the CLI and produces a raw traceback.
Consider catchingKeyboardInterrupt(e.g., inlaunch()/prepare_args()or in__main__) and exiting gracefully.

In `@libs/terminal_ui.py.orig` around lines 155 - 158, TerminalUI currently lets a
KeyboardInterrupt from TerminalUI._select_option propagate (on Esc/Ctrl-C)
because TerminalUI.launch and prepare_args do not catch it; update the call
sites (e.g., wrap TerminalUI.launch and prepare_args invocations) to catch
KeyboardInterrupt and exit cleanly (call sys.exit(0) or print a short
user-friendly message) instead of letting it propagate to interpreter.py;
alternatively add a top-level try/except KeyboardInterrupt in __main__ or in
interpreter.py around the main dispatch so any KeyboardInterrupt raised by
TerminalUI._select_option is handled gracefully and no raw traceback is printed.
