What's Wrong?

Every time I open Claude from within a Jetbrains IDE (using the beta plugin), it writes " ↑ Install the PyCharm plugin from the JetBrains Marketplace: https://docs.claude.com/s/claude-code-jetbrains "

I'd like the "ad" to go away, specially because I have both Intellij's and PyCharm's plugin for Claude already installed.

Claude made a diagnostic of the situation, and here's what he said:

Root cause: Claude Code detects TERMINAL_EMULATOR=JetBrains-JediTerm (set by PyCharm's terminal) and shows the install message. It does check for the plugin in ~/.local/share/JetBrains/PyCharm*/claude-code-jetbrains-plugin — and that directory does exist on your system — but the check is async

and the banner renders before it completes.

The fix would be setting autoInstallIdeExtension: false in ~/.claude/settings.json, but the settings validator rejects it as an unrecognized field (even though the binary clearly reads it).

The simplest workaround right now is to add it to the env block to override TERMINAL_EMULATOR, but that would break IDE integration. There's no clean supported option.

Recommendation: File a bug report at https://github.com/anthropics/claude-code/issues — this is clearly a bug: the plugin is installed and the directory check confirms it, but the async timing causes the message to always show. The fix on their end would be either awaiting the check before first

render, or honoring autoInstallIdeExtension in the settings schema.

And because of this, here I am, and this is my bug report.

What Should Happen?

The suggestion to install the extension should not show up if the plugin is already installed
