When you create, change or review iOS UI, follow the iPhone Duo skill at .agents/skills/iphone-duo-design/SKILL.md: - Lay out from size classes and container bounds, never from orientation, idiom or UIScreen.main. One narrow layout and one wide layout cover closed, open, portrait, landscape, and Split View. - Follow the skill's references/fold-aware-layout.md for path order, pane pairs, reach, and the toolbar. Destructive actions, including Delete, stay in the overflow menu. - Use system bars, split views and ArrangementView / UIArrangementViewController. Keep custom…

  • Where files are headingNew AGENTS.md files have more rules about keeping secrets out of the code, and fewer about code style.

    Of the AGENTS.md files we read, the 31,542 first seen in the last six months, against the older ones: the kind of rule that gained most share, and the kind that lost most. About files like this in general, not this one, and an estimate, since a kind is a pattern in the words.

We split this AGENTS.md into the rules it gives an agent

5 rules. About 0 are common, 0 are distinctive, and 5 are very specific to this project.

    Many files like this have a rule of this kind.

  1. Very specific:

    When you create, change or review iOS UI, follow the iPhone Duo skill at .agents/skills/iphone-duo-design/SKILL.md:

    line 8
  2. Very specific:

    Follow the skill's references/fold-aware-layout.md for path order, pane pairs, reach, and the toolbar.

    line 10
  3. Very specific:

    Use system bars, split views and ArrangementView / UIArrangementViewController.

    line 11
  4. Very specific:

    Before finishing UI work, run .agents/skills/iphone-duo-design/scripts/duo-lint <changed Swift paths> and address every finding.

    line 12
  5. Very specific:

    Use only Apple's documentation for iPhone Duo facts (see the skill's references/sources.md).

    line 13

≈ “Common” is an estimate: at least 1 in 5 of the 40,246 AGENTS.md files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

iPhone Duo

When you create, change or review iOS UI, follow the iPhone Duo skill at .agents/skills/iphone-duo-design/SKILL.md:

  • Lay out from size classes and container bounds, never from orientation, idiom or UIScreen.main. One narrow layout and one wide layout cover closed, open, portrait, landscape, and Split View.
  • Follow the skill's references/fold-aware-layout.md for path order, pane pairs, reach, and the toolbar. Destructive actions, including Delete, stay in the overflow menu.
  • Use system bars, split views and ArrangementView / UIArrangementViewController. Keep custom controls off active .division reserved regions. Keep text and controls out from under the toolbar.
  • Before finishing UI work, run .agents/skills/iphone-duo-design/scripts/duo-lint <changed Swift paths> and address every finding.
  • Use only Apple's documentation for iPhone Duo facts (see the skill's references/sources.md). Never invent API names or dimensions. fold-aware-layout.md is belweave's practice, not an Apple page.
  • Build the full layout with Xcode 27.1 or later and the iOS 27.1 SDK. Upload iPhone Duo screenshots so the product page can show the optimized-for-iPhone-Duo badge (references/app-store.md).
  • Compare a few layouts, scrub tools/fold-preview.html, and test on a real iPhone Duo as well as the simulator before you ship.
