Bug Report

Feature Area: TUI Prompt Multiline Input
Severity: Medium (backlog)
Found by: UAT tester instance uat-tui-worker-1
Spec reference: docs/specification.md §Multiline Detection (lines ~30036–30046)

What Was Tested

The src/cleveragents/tui/widgets/prompt.py and src/cleveragents/tui/input/modes.py were inspected for multiline detection.

Expected Behavior (from spec)

The prompt auto-detects multiline input and switches the prompt symbol to ☰:

Condition	Result
Input contains `\n` (newline character)	Switch to multiline mode
Input contains triple backticks (```)	Switch to multiline mode
`shift+enter` or `ctrl+j` pressed	Insert newline, switch to multiline
All newlines removed	Revert to single-line mode

In multiline mode:

enter inserts a newline
ctrl+enter submits
Prompt symbol changes to ☰

In single-line mode:

enter submits
Prompt symbol is ❯ (normal), $ (shell), or ☰ (multiline)

Actual Behavior

The PromptInput widget in widgets/prompt.py is a thin wrapper around Textual's Input widget:

class PromptInput(_InputBase):
    def consume_text(self) -> PromptSubmitted:
        text = self.value
        self.value = ""
        return PromptSubmitted(text=text)

There is no multiline detection, no shift+enter/ctrl+j handling, no ctrl+enter submit in multiline mode, and no prompt symbol switching (❯ → ☰).

The InputModeRouter.detect_mode() only checks the first character for / or ! — it does not detect multiline content.

Code Location

Widget: src/cleveragents/tui/widgets/prompt.py — PromptInput class
Router: src/cleveragents/tui/input/modes.py — InputModeRouter.detect_mode()
Missing: Multiline mode detection (newline or triple backtick in content)
Missing: shift+enter / ctrl+j key handlers to insert newline
Missing: ctrl+enter submit in multiline mode
Missing: Prompt symbol switching (❯ / $ / ☰)

Impact

Users cannot compose multi-line prompts (e.g., code blocks with triple backticks)
shift+enter does not insert a newline
The prompt symbol never changes to ☰ for multiline mode
Pasting multi-line content submits immediately on the first newline
