Bug Report

Spec Reference

Specification line 29073 (Prompt hint bar), lines 29304–29311 (Input Mode Table)

Expected Behavior (from spec)

The TUI prompt hint bar (spec line 29073) shows:

▌@▐ refs  ▌/▐ commands  ▌!▐ shell

The spec also references $ prefix for env vars in the shell mode context (spec line 29085):

PromptTextArea with mode-dependent symbol (❯ normal, $ shell, ☰ multi-line)

The $ prefix should expand environment variables inline in the prompt, allowing users to reference env vars like $HOME, $PATH, etc. in their messages or shell commands.

Actual Behavior (from code analysis)

src/cleveragents/tui/input/modes.py InputModeRouter.detect_mode() (lines 49–56):

@staticmethod
def detect_mode(text: str) -> InputMode:
    stripped = text.lstrip()
    if stripped.startswith("/"):
        return InputMode.COMMAND
    if stripped.startswith("!"):
        return InputMode.SHELL
    return InputMode.NORMAL

No $ prefix handling. A message starting with $HOME would be treated as InputMode.NORMAL and sent to the actor as plain text, not expanded as an env var reference.

src/cleveragents/tui/input/shell_exec.py also has no env var expansion logic.

Code Location

src/cleveragents/tui/input/modes.py — detect_mode() lines 49–56
src/cleveragents/tui/input/shell_exec.py — no env var expansion

Steps to Reproduce (Code Analysis)

Read src/cleveragents/tui/input/modes.py lines 49–56
Observe: no $ prefix handling
Compare with spec line 29073 (prompt hint bar showing $ prefix)

Severity

Low — env var expansion is a convenience feature. Backlog item.
