No session selected.

Error message

No session selected.

What it means

On Windows, bare `codewhale resume` cannot show a fuzzy picker, so it lists sessions and prompts `Session id/prefix (Enter to cancel):`. Reading the line with `read_line` succeeds even for empty input, so an empty trimmed answer — the documented cancel gesture — surfaces as this bail. The session id or a unique prefix is required to proceed, or `--last` skips the prompt.

Solutions

1. Type a session id or a unique prefix from the printed list and press Enter
2. Skip the prompt entirely: `codewhale resume --last`
3. For scripts, pass the session explicitly: `codewhale resume <session-id>`

Example fix

# before
Session id/prefix (Enter to cancel): <Enter>
# No session selected.

# after
$ codewhale resume --last

#!/usr/bin/env bash
# on Windows or in scripts, never rely on the picker prompt
if [ -n "${SESSION_ID:-}" ]; then
  exec codewhale resume "$SESSION_ID"
else
  exec codewhale resume --last
fi

When it happens

Trigger: Running `codewhale resume` on Windows and pressing Enter at the selection prompt; typing only whitespace; stdin closed/EOF so the read returns an empty line.

Common situations: Users testing the prompt and pressing Enter to 'skip'; terminal paste issues; scripts calling `codewhale resume` non-interactively on Windows where stdin yields EOF.
