* Route native projects to native command variants for audit and adapt Follow-up to #269. The web audit.md and adapt.md carried "translate this yourself" Platform notes, so a native invocation paid for the full web file (~1.8k / ~2.6k tokens, mostly inapplicable) and did error-prone run-time translation. Authored with AI assistance (Claude Code) under maintainer direction. - New reference/audit.native.md and reference/adapt.native.md: authored native content (VoiceOver/TalkBack, platform conformance, adaptivity dimensions; phone-to-tablet, platform-to-platform, web-to-native strategies). One variant per command covers ios, android, and adaptive; per-OS specifics stay in the platform refs Setup loads regardless. - SKILL.src.md: Commands table lists the variants; Setup step 2 reads the variant instead of the web file when the platform is native. - audit.md / adapt.md: Platform sections replaced with a one-line web-only guard pointing at the variant. - animate.md / layout.md: Platform sections deleted; the Motion and Layout sections of the already-loaded platform refs carry that content. Web users now pay zero tokens for the platform axis in these files. - Skill-behavior scenario 15 pins the route-instead behavior (passes live on claude-sonnet-4-6); CLAUDE.md documents the variant convention. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Phrase command-reference routing as one rule, not rule-plus-exception Copilot review catch: step 2 said "MUST read reference/<command>.md" and then carved out the native variant, which invites loading both files. Now a single rule: read the web reference or the table's native variant, one file, not both. Scenario 15 re-verified live. Applied with AI assistance (Claude Code) under maintainer direction. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Anchor native runs in animate/layout, drop loaded-refs assumption Review-thread fixes, applied with AI assistance (Claude Code) under maintainer direction: - Greptile: deleting the animate/layout Platform sections left native runs alone with web tooling instructions (CSS keyframes, GSAP, Grid, clamp()). Restore a one-line anchor in each pointing at the loaded platform reference's Motion / Layout section (~20 tokens, not the old restatements). - Bugbot: audit.native.md and adapt.native.md asserted the platform refs were "already loaded in Setup", but the command reference loads at step 2, before step 5. Now they instruct: read the platform reference first if Setup hasn't already. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Carry the native-variant rule into routing rules 2 and 3 Bugbot catch: Setup step 2 routed native projects to the variant, but routing rules 2 and 3 (the operative text at command time) still said to load the generic reference file. Both now reference the same one-file variant rule. Applied with AI assistance (Claude Code) under maintainer direction. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Point animate/layout native anchors at the files, not "loaded" refs Bugbot catch, same class as the variant wording fix: the anchor lines said "the loaded platform reference" but command files load at step 2, before the platform refs at step 5. Both anchors now name the files and instruct reading them first if Setup hasn't already. Applied with AI assistance (Claude Code) under maintainer direction.

Additional context needed: target platforms/devices and usage contexts.
Adapt an existing native design (ios / android / adaptive) to a different context: another device class, orientation, platform, or origin. The trap is treating adaptation as scaling. The job is rethinking the experience for the new context, inside the platform conventions of ios.md / android.md; read the target platform's reference before planning if Setup hasn't already.
Assess Adaptation Challenge
- Source context: what was it designed for, and what assumptions did it make? (Phone-only? Portrait-only? One platform's idioms? A website?)
- Target context: which device class (phone, tablet, foldable), orientation, platform, and usage posture (one-handed on the go vs two-handed at rest)?
- What breaks: navigation that doesn't fit the target, layouts that stretch instead of restructure, gestures or controls that don't exist there?
Adaptation Strategies
Phone → Tablet (iPad / large screens)
- Restructure, don't stretch. A scaled-up phone UI on a tablet is the failure mode. Use size classes (iOS) / window size classes (Android) to switch structure.
- Navigation changes shape: tab bar stays or becomes a sidebar on iPad; Android navigation bar becomes a rail or drawer on expanded width.
- Use the width: split view / master-detail (list + detail side by side), multi-column grids, popovers where phones used sheets.
- Multitasking is a size, not an edge case: iPad Split View and Android multi-window can hand you a phone-width window on a tablet; size-class-driven layout handles both for free.
Orientation & foldables
- Landscape restructures (side-by-side panes, repositioned controls); never clip or letterbox. Lock orientation only when the task truly demands it.
- Foldables (Android): react to posture and hinge via window size classes; test folded, unfolded, and tabletop.
Platform → platform (iOS ↔ Android)
Translate idioms; never transplant them:
| iOS | Android |
|---|---|
| Tab bar | Navigation bar / rail / drawer |
| Edge-swipe back, back chevron | Predictive Back gesture / button |
| Switch, segmented control, system pickers | Material switch, chips, Material pickers |
| Action sheet | Bottom sheet / Material dialog |
| SF Symbols, SF Pro, Dynamic Type | Material Symbols, Roboto, sp scaling |
| Semantic system colors, materials | Material color roles, tonal elevation |
| System push/sheet transitions | Container transform, shared-axis, fade-through |
Rebuild navigation and controls in the target's vocabulary; carry over the brand's expressive layer (palette intent, type accent, motion personality) through the target's theming system.
Web → native (porting a website or web app)
Reconform, don't reflow. Replace web navigation with the platform's model, HTML-shaped controls with platform controls, hover affordances with touch-first ones, and px-based type with Dynamic Type / sp. Then treat the result to the full platform reference; the slop test there is the acceptance bar.
Implement & Verify
- Drive structure from size classes / window size classes, never from device-model checks.
- Respect safe areas and window insets in every new configuration (notch, hinge, status bar, keyboard).
- Test on simulators for breadth, then real hardware for truth: at least one phone and one tablet per shipped platform, both orientations, split-screen where supported.
When the adaptation feels native to each context, hand off to {{command_prefix}}impeccable polish for the final pass.
NEVER:
- Ship a stretched phone layout on a tablet
- Port one platform's controls or navigation onto the other
- Hide core functionality on smaller devices (if it matters, make it work)
- Lock orientation to dodge a layout bug
- Trust simulators alone (posture, gestures, and performance need hardware)
