Bug Report

Feature Area: TUI — Prompt Architecture

Severity: High (prompt functionality severely limited)

What Was Tested

The prompt widget architecture as defined in the specification (§ Prompt Architecture Detail, §MainScreen Layout).

Expected Behavior (from spec)

The spec defines a PromptTextArea with:

Mode-dependent symbol: ❯ (normal), $ (shell), ☰ (multi-line)
Multiline detection: Auto-switches to ☰ when input contains \n, triple backticks, or shift+enter/ctrl+j is pressed. In multiline mode, enter inserts newline; ctrl+enter submits.
History navigation: Two independent JSONL history files per project:
- ~/.local/state/cleveragents/history/<project-hash>/prompt.jsonl
- ~/.local/state/cleveragents/history/<project-hash>/shell.jsonl
- up at row 0 → previous history entry
- down at last row → next history entry
- Capped at 10,000 entries
Key passthrough: When conversation Window has focus, printable characters forwarded to prompt TextArea

Actual Behavior (from code analysis)

The PromptInput in src/cleveragents/tui/widgets/prompt.py extends Textual's Input widget (not TextArea):

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

Issues:

Input is single-line only — no multiline support, no ☰ mode
No mode-dependent prompt symbol — always shows default Input placeholder
No history navigation — no JSONL history files, no up/down history
No key passthrough — conversation widget doesn't forward keypresses to prompt
No shift+enter/ctrl+j for newline insertion

Steps to Reproduce

Run agents tui
Press shift+enter — no newline inserted (single-line Input)
Press up arrow — no history navigation
Type a multi-line message — impossible with single-line Input

Code Location

src/cleveragents/tui/widgets/prompt.py — extends Input not TextArea

Impact

The TUI prompt is severely limited compared to the spec:

Cannot compose multi-line prompts
No prompt history
No mode-dependent visual feedback
Cannot paste multi-line content
