Run Inline Prompt runs diagnostics instead of accepting a prompt

[aadorian]

Summary

The Run Inline Prompt command (opencode-walkthrough.runInline) does not match its label or walkthrough step 2 ("Run a Prompt"). When the OpenCode CLI is installed, it dumps version/auth/models to the terminal instead of prompting the user for input.

Steps to Reproduce

1. Install OpenCode CLI (opencode --version succeeds)
2. Run OpenCode: Run Inline Prompt from the command palette, sidebar, or walkthrough step 2
3. Observe terminal output

Expected Behavior

An input box should appear asking for a prompt, then run:

opencode run "user prompt"

Actual Behavior

Terminal runs a diagnostic chain:

echo "OpenCode ${version}" && opencode --version && opencode auth ls && opencode models

Impact

• Walkthrough step 2 completion is misleading (user thinks they ran a prompt)
• Core advertised feature is broken for installed users
• Sidebar welcome link "Run Inline Prompt" fails user expectations
