The STATUS_META object defines identical cardClass values for all three status types ("done", "action", and "blocked"). This makes the status field redundant since it doesn't affect the card styling. Either differentiate the card classes based on status, or remove the unused status field from the type definition if the styling is intentionally the same.

If these styles are meant to be different, consider updating them like:

const STATUS_META: Record<StepStatus, { cardClass: string, inactiveIcon: string }> = {
  done: {
    cardClass: "border-emerald-500/30 bg-emerald-500/5 transition-all duration-300 hover:shadow-lg dark:border-emerald-500/40",
    inactiveIcon: "text-emerald-500 dark:text-emerald-400",
  },
  action: {
    cardClass: "border-primary/30 bg-background transition-all duration-300 hover:shadow-lg dark:border-primary/40 dark:shadow-primary/5",
    inactiveIcon: "text-muted-foreground",
  },
  blocked: {
    cardClass: "border-muted/30 bg-muted/5 transition-all duration-300 dark:border-muted/40",
    inactiveIcon: "text-muted-foreground",
  },
};

The handleItemClick function is always passed to StepCard but only uses the itemId parameter without using it. It immediately calls toggleStepCompletion(stepId) regardless of which specific item was clicked. This could be confusing since the function signature suggests per-item behavior but actually performs per-step behavior.

Consider either:

1. Renaming to clarify it's a step-level action: onStepItemClick
2. Or removing the itemId parameter if it's not needed:

const handleItemClick = (stepId: StepId) => {
  toggleStepCompletion(stepId);
};

And update the call site to: onItemClick={() => handleItemClick(step.id)}

The CardDescription has conditional opacity that transitions between opacity-0 when collapsed and opacity-100 when expanded. However, when collapsed (opacity-0), the subtitle text is still rendered in the DOM and takes up space, which could cause layout issues. The text becomes invisible but still occupies vertical space.

Consider using display: none or removing it from the DOM when collapsed:

{props.isExpanded && (
  <CardDescription className="text-sm">
    {props.step.subtitle}
  </CardDescription>
)}

Or use a height transition instead of just opacity if you want the animation effect.

[nitpick] The chevron toggle button in the CardHeader has both onClick handlers - one on the button itself (line 561-563) and one on the parent CardHeader (line 526). The button's handler calls e.stopPropagation() to prevent the parent's handler from firing, but this creates redundancy since both handlers call the same props.onToggle() function.

The e.stopPropagation() is unnecessary here. Consider simplifying by removing the button's onClick handler and letting it bubble to the parent:

<button
  type="button"
  className="flex shrink-0 items-center justify-center rounded-md p-1.5 transition-colors hover:bg-accent"
  aria-label={props.isExpanded ? "Collapse section" : "Expand section"}
>

The action button is displayed in the CardFooter for all steps, but it's only relevant for the "project" and "keys" steps. For other steps (env-vars, deploy, verify), getActionButton() returns null, which still renders an empty CardFooter taking up space.

Consider conditionally rendering the CardFooter only when there's an action button:

{getActionButton() && (
  <CardFooter className="flex justify-end">
    {getActionButton()}
  </CardFooter>
)}

Or cache the button result to avoid calling the function twice:

const actionButton = getActionButton();
// ...
{actionButton && (
  <CardFooter className="flex justify-end">
    {actionButton}
  </CardFooter>
)}

The error alert is rendered inside the step's content area but only applies to the "keys" step. However, the error prop is passed to all StepCard instances (line 397), causing the error to potentially display in steps where it's not relevant.

Consider only passing the error prop when rendering the "keys" step:

<StepCard
  step={step}
  isExpanded={isExpanded}
  onToggle={() => handleStepToggle(step.id)}
  onGenerateKeys={step.id === "keys" && !keys ? handleGenerateKeys : undefined}
  isGenerating={isGenerating}
  error={step.id === "keys" ? error : null}
  onItemClick={(itemId) => handleItemClick(step.id, itemId)}
/>

[nitpick] The randomInRange function is defined inside the effect callback on line 278-280. Since this function doesn't depend on any variables from the effect scope and is only used within the interval callback, it would be more efficient and clearer to define it outside the effect or even outside the component to avoid recreating it on every completion.

Consider moving it outside the effect:

function randomInRange(min: number, max: number) {
  return Math.random() * (max - min) + min;
}

// Trigger confetti when all tasks are completed
useEffect(() => {
  // ... rest of the effect
}, [vercelProgress.completed, vercelProgress.total]);

The confetti effect interval is not properly cleaned up when the component unmounts before all tasks are completed. The cleanup function on line 302-304 only runs when the effect dependencies change or when allCompleted becomes true. If the component unmounts while the confetti is running (e.g., user navigates away), the interval will continue running, potentially causing memory leaks.

Consider storing the interval in a ref and cleaning it up in the effect's cleanup function unconditionally:

useEffect(() => {
  const allCompleted = vercelProgress.completed === vercelProgress.total && vercelProgress.total > 0;
  const prevAllCompleted = prevAllCompletedRef.current;

  if (prevAllCompleted !== undefined && !prevAllCompleted && allCompleted) {
    const duration = 3000;
    const animationEnd = Date.now() + duration;
    const defaults = { startVelocity: 30, spread: 360, ticks: 60, zIndex: 9999 };

    function randomInRange(min: number, max: number) {
      return Math.random() * (max - min) + min;
    }

    const interval = setInterval(() => {
      const timeLeft = animationEnd - Date.now();

      if (timeLeft <= 0) {
        clearInterval(interval);
        return;
      }

      const particleCount = 50 * (timeLeft / duration);
      const result = confetti.default({
        ...defaults,
        particleCount,
        origin: { x: randomInRange(0.1, 0.9), y: 0 },
      });
      if (result) {
        runAsynchronously(result, { noErrorLogging: true });
      }
    }, 250);

    return () => clearInterval(interval);
  }

  prevAllCompletedRef.current = allCompleted;
}, [vercelProgress.completed, vercelProgress.total]);
