Start with the statusLine command path and reproduce the issue using the settings.json configuration and statusline-command.ps1 on Windows. Compare WaveTerm's stdin handling with the described Windows Terminal behavior, then verify that the command receives the Claude Code JSON payload and produces model, context, and token information instead of the fallback output.

Descrizione

Description

When using Claude Code inside WaveTerm, the custom statusLine command does not receive any JSON data via stdin, causing the statusline to fall back to a generic output instead of displaying model info, context usage, token counts, etc.

How Claude Code statusLine works

Claude Code supports a custom statusline via settings.json:

"statusLine": {
  "type": "command",
  "command": "pwsh -NoProfile -File statusline-command.ps1"
}

Claude Code is supposed to pipe a JSON payload to the command's stdin after each response. The JSON includes model.display_name, context_window.used_percentage, rate_limits, cwd, session_name, etc.

What happens in WaveTerm

The command is executed, but stdin is empty. The script reads nothing from [Console]::In.ReadToEnd(), causing it to hit the fallback and output just claude instead of the full statusline.

The same script works correctly in Windows Terminal where stdin is properly piped.

Steps to Reproduce

Configure Claude Code statusLine with a custom command that reads from stdin
Run Claude Code inside WaveTerm
Observe the statusline only shows the fallback output

Expected Behavior

The custom statusline command should receive the JSON payload via stdin, same as in other terminals.
