26-83: Shared tool state looks good; consider future-proofing around no-copy usage

The refactor to share code, lang, copy, toast, askAI, and toolbox and to normalize code blocks is consistent with the existing copy/run behavior and keeps the logic coherent.

One consideration: no-copy now implicitly also disables Ask AI (via the same ancestor class check). If you expect cases where AI should be available even when copying is not (or vice versa), it may be worth splitting this into more explicit flags (for example, no-copy vs no-ai) to avoid overloading one class with multiple meanings.

84-110: Ask AI button wiring is correct; watch for Kapa load timing

The Ask AI button wiring (creation, SVG icon, event handler) looks correct and mirrors the copy button structure, including reuse of the no-copy suppression logic.

One nuance: the button is only created if window.Kapa is truthy at script execution time. If Kapa is injected asynchronously after this script runs, users won’t see the button even though AI eventually becomes available. If that’s a realistic scenario, consider:

• Always rendering the button and doing the window.Kapa check only on click, or
• Re-running the toolbox initialization (or toggling visibility) once Kapa finishes loading.

175-195: handleAskAI reuses console normalization; consider preserving visual snippet and enriching prompt

The handler correctly mirrors writeToClipboard behavior: trimming trailing spaces, normalizing console snippets via extractCommands, and then opening Kapa with a Markdown-formatted prompt. This alignment reduces surprises between “copy” and “ask AI”.

Two potential improvements:

1. Preserve the exact visual snippet for AI
   For console blocks, extractCommands flattens multi-line $ prompts into a single &&-chained command string. That’s great for copying into a shell, but users might expect the AI prompt to match what they see on the page (including $ prompts and line breaks). You could:

   • Use the raw text for Ask AI, or
   • Include both, for example:

   var aiPromptText =
     'Explain this console snippet (shown as run commands below):\n\n' +
     'Original snippet:\n\n```\n' + code.innerText.replace(TRAILING_SPACE_RX, '') + '\n```\n\n' +
     'Commands:\n\n```\n' + extractCommands(text) + '\n```'

2. Add minimal API robustness
   Before calling kapa.open, consider guarding against unexpected API shape to avoid runtime errors if the integration changes:

   if (kapa && typeof kapa.open === 'function') {
     kapa.open({ mode: 'ai', query: aiPromptText, submit: true })
   } else {
     console.warn('Kapa AI is not available or misconfigured.')
   }

These are non-blocking but would make the integration more resilient and the AI explanation closer to what users see.

1490-1513: Inline-flex copy button + hover transitions look consistent with toolbox layout

Switching .copy-button to inline-flex with position: relative and adding smooth hover transitions for SVG/img icons fits well with the existing .source-toolbox flex layout and supports the new toast positioning.

One thing to keep in mind: both .copy-button and .ask-ai-button set outline: none;, which removes the default keyboard focus indicator. This was already the case for copy, but it now extends to the new AI control as well. If keyboard accessibility is a concern, consider reintroducing a visible focus style (e.g., a focus ring or underline) instead of globally suppressing outline.

1563-1590: Ask AI button/icon styling aligns with copy button; spacing may need fine-tuning

The .ask-ai-button and .ask-ai-icon styles mirror the copy button’s structure and sizing, and the hover color transition on the sparkles path nicely matches the copy icon behavior. This should integrate cleanly into .source-toolbox alongside the language label and run/copy buttons.

If, during visual QA, the icons or separators feel cramped (e.g., “Copy | Ask AI” touching too closely), consider a small horizontal gap or padding between adjacent buttons, but that’s purely cosmetic and can be tuned later.
