AI Capture Ratio Implementation Plan

For agentic workers: REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (- [ ]) syntax for tracking.

Goal: Change the non-mobile AI capture composer to a 70 / 30 text-to-attachments split, stack attachment previews one per row, and render example prompts as a masonry-style cluster.

Architecture: Keep the page-level AI capture placement unchanged and make the entire change inside AIToolbar. Lock the new layout with source-based tests in tests/ai-toolbar.test.ts, then make the smallest JSX/class updates needed in src/components/ai-toolbar.tsx to satisfy them.

Tech Stack: Bun test runner, Next.js, React, TypeScript, Tailwind utility classes, Biome, useIsMobile


Task 1: Lock the 70 / 30 Desktop Composer Contract

Files:

  • Modify: tests/ai-toolbar.test.ts

  • Test: tests/ai-toolbar.test.ts

  • Step 1: Write the failing test

Replace the current non-mobile composer assertion so it expects a 70 / 30 split instead of equal-width columns.

test("desktop composer uses a 70 / 30 row when the page gives it full-width space", () => {
	const source = readToolbarSource();

	expect(source).toContain("isMobile");
	expect(source).toContain('? "grid gap-3"');
	expect(source).toContain(
		': "grid gap-3 grid-cols-[minmax(0,0.7fr)_minmax(0,0.3fr)]"',
	);
});
  • Step 2: Run test to verify it fails

Run: bun test tests/ai-toolbar.test.ts

Expected: FAIL because src/components/ai-toolbar.tsx still contains the equal-width non-mobile grid.

  • Step 3: Write minimal implementation

Update the non-mobile composer grid in src/components/ai-toolbar.tsx.

Change this branch:

: "grid gap-3 grid-cols-[minmax(0,1fr)_minmax(0,1fr)]"

To:

: "grid gap-3 grid-cols-[minmax(0,0.7fr)_minmax(0,0.3fr)]"
  • Step 4: Run test to verify it passes

Run: bun test tests/ai-toolbar.test.ts

Expected: PASS for the updated desktop composer test.

  • Step 5: Commit
git add tests/ai-toolbar.test.ts src/components/ai-toolbar.tsx
git commit -m "refactor(ai-toolbar): use 70-30 desktop composer split"

Task 2: Lock One-Preview-Per-Row Attachments

Files:

  • Modify: tests/ai-toolbar.test.ts

  • Modify: src/components/ai-toolbar.tsx

  • Test: tests/ai-toolbar.test.ts

  • Step 1: Write the failing test

Add a test that rejects the old desktop grid-cols-2 preview layout and expects a row-stacked preview container.

test("attachment previews stack one per row instead of using a two-column desktop grid", () => {
	const source = readToolbarSource();

	expect(source).not.toContain('"mt-3 grid gap-2 grid-cols-2"');
	expect(source).toContain('"mt-3 grid gap-2"');
});
  • Step 2: Run test to verify it fails

Run: bun test tests/ai-toolbar.test.ts

Expected: FAIL because the preview container still uses the desktop grid-cols-2 branch.

  • Step 3: Write minimal implementation

Simplify the preview container in src/components/ai-toolbar.tsx so it uses one shared stacked grid for all widths.

Replace:

className={
	isMobile ? "mt-3 grid gap-2" : "mt-3 grid gap-2 grid-cols-2"
}

With:

className="mt-3 grid gap-2"

Keep each preview card as-is so the image and remove button behavior do not change.

  • Step 4: Run test to verify it passes

Run: bun test tests/ai-toolbar.test.ts

Expected: PASS for the stacked-preview contract.

  • Step 5: Commit
git add tests/ai-toolbar.test.ts src/components/ai-toolbar.tsx
git commit -m "refactor(ai-toolbar): stack attachment previews by row"

Task 3: Lock Masonry-Style Example Prompts

Files:

  • Modify: tests/ai-toolbar.test.ts

  • Modify: src/components/ai-toolbar.tsx

  • Test: tests/ai-toolbar.test.ts

  • Step 1: Write the failing test

Add a test that locks the example prompt area to a clustered layout instead of a flat single-row strip.

test("example prompts use a masonry-style cluster inside the composer footer", () => {
	const source = readToolbarSource();

	expect(source).toContain("Try:");
	expect(source).toContain("columns-2");
	expect(source).toContain("break-inside-avoid");
	expect(source).toContain("w-full text-left");
});
  • Step 2: Run test to verify it fails

Run: bun test tests/ai-toolbar.test.ts

Expected: FAIL because the current prompt chips still live in a flat wrapped flex row.

  • Step 3: Write minimal implementation

Refactor only the example prompt block in src/components/ai-toolbar.tsx.

Use this structure:

<div className="columns-2 gap-2">
	{examplePrompts.map((prompt) => (
		<Button
			key={prompt}
			type="button"
			variant="secondary"
			size="sm"
			className="mb-2 h-auto w-full break-inside-avoid whitespace-normal rounded-2xl px-3 py-2 text-left text-[11px]"
			onClick={() => onAiTemplateSelect(prompt)}
			disabled={aiLoading || !canUseAi}
		>
			{prompt}
		</Button>
	))}
</div>

Keep the surrounding footer copy and disabled behavior intact. Do not add new helper components.

  • Step 4: Run test to verify it passes

Run: bun test tests/ai-toolbar.test.ts

Expected: PASS for the prompt-cluster contract.

  • Step 5: Commit
git add tests/ai-toolbar.test.ts src/components/ai-toolbar.tsx
git commit -m "refactor(ai-toolbar): cluster example prompts in masonry layout"

Task 4: Full Verification

Files:

  • Test: tests/ai-toolbar.test.ts

  • Test: tests/home-page-layout.test.ts

  • Verify: src/components/ai-toolbar.tsx

  • Step 1: Run targeted layout tests

Run: bun test tests/ai-toolbar.test.ts tests/home-page-layout.test.ts

Expected: PASS with the AI toolbar and page layout contracts still green.

  • Step 2: Run the full test suite

Run: bun test

Expected: PASS with no new failures.

  • Step 3: Run typecheck

Run: bun run type:check

Expected: PASS.

  • Step 4: Run lint

Run: bun run lint

Expected: PASS, with only the pre-existing src/lib/compose-refs.ts warning if it still appears.

  • Step 5: Commit

If Task 4 introduced no code changes, skip a commit here. If a tiny verification-driven tweak was required, commit only that tweak:

git add src/components/ai-toolbar.tsx tests/ai-toolbar.test.ts
git commit -m "test(ai-toolbar): verify desktop composer layout contracts"
