No. The issues you listed are related to the CLI tool, not to VS Code Extension

I am eagerly anticipating the OpusPlan feature in the VSCode Claude Code extension. It promises to be a highly valuable addition.

Unfortunately, it seems that no official boys care here. They have added a "stale". No hope.

This would greatly improve DX and make the extension on par with the CLI tool. I'm sure it would help with resource utilization on the Anthropic side as well as fewer requests would be directed to Opus for the implementation aspect of the development cycle.

+1. Very useful

please add this feature.

Looks like this has been added. can anyone verify?

What version of the extension do you have? I just updated to version 2.1.76 in VSCode, but no change other than seeing Opus 1m is now the "default" model.

It's v2.1.78 as of today.

I've just upgraded to this and still don't see the 'Opus Plan Mode' option 😔
(VS Code 1.111.0, Claude Code for VS Code 2.1.78, MacOS 26.3, Claude Pro user)

For me, it is only visible in the model selection, after setting opusplan as the default model.

Problem solved! I managed to get the option to appear by adding this to my settings.json in my user dir

{"model": "opusplan"}

Confirming this workaround works, but would be nice if it was supported out of the box like the CLI.

For those that may be struggling, hopefully the below steps help.

1. Open your ~/.claude/settings.json file (%UserProfile%/.claude/settings.json on Windows) to do this globally. If you only want to enable this for your current project, open the .claude/settings.json file in your project.
2. Add "model": "opusplan" to the file or change the existing setting if it exists to set the default model used when opening up the extension (applies to CLI as well).

To clarify, your settings.json should look like this as an example with the model being a root level setting and not nested under some other complex settings object:

Yes:

{
    "model": "opusplan", 
    "skipDangerousModePermissionPrompt": true, 
    "othersetting": "value", 
    ........
}

No:

{
    "env": {
        "model": "opusplan", 
    }, 
    "skipDangerousModePermissionPrompt": true, 
    "othersetting": "value", 
    ........
}

The next time you type /model, you should see the below.

opusplan + Bypass permissions conflict in VSCode extension — no visual feedback

Beyond just adding opusplan to the dropdown, there's a deeper UX issue worth addressing:

In the VSCode extension, opusplan is fundamentally incompatible with Bypass permissions mode (the preferred mode for uninterrupted work). The two modes are mutually exclusive:

• Bypass permissions → no planning phase → Opus never activates → opusplan silently falls back to Sonnet the entire session
• Plan mode → Opus activates → but you lose Bypass permissions

There's also zero visual feedback when opusplan is active. No indicator of which model is actually running. The user has no way to verify whether Opus ever ran, which completely erodes trust in the feature.

Current workaround (manual):

1. Set model to Opus + enable Plan mode
2. Discuss and plan
3. Manually switch to Sonnet + Bypass permissions for execution

This is exactly what opusplan is supposed to automate — but in the VSCode extension, the user has to do it manually with no help from the alias.

Expected behavior: opusplan should work seamlessly with Bypass permissions (Opus for the internal planning phase, then auto-switch to Sonnet for execution), or the extension should at minimum clearly communicate that opusplan requires Plan mode to function and explain the tradeoff.

I really hope they add this, it's really clunky to have to

• escape out of accepting the plan from opus
• /model into sonnet
• type continue
• then finally accept the plan

bad ux especially when the option already exists in the cli

are there any recent workarounds for this, or is the bypass permissions / opus plan conflict still happening?

I think you can use a prompt to achieve similar results
