Axiom Watchos

If you're building anything for Apple Watch, this is your routing hub. It covers the full watchOS stack: independent apps, Smart Stack widgets, complications, controls, Watch Connectivity for paired devices, background tasks, and migrating off deprecated ClockKit. The quick reference table is legitimately helpful for knowing which doc handles what, and the conflict resolution section clearly splits responsibilities with related skills like axiom-swiftui for cross-platform patterns and axiom-health for workout sessions. It's opinionated about when to use watchOS-specific approaches versus shared SwiftUI code, which saves you from guessing. Basically assumes you know iOS development and need the watch-specific gotchas and APIs.

watchOS Development

You MUST use this skill for ANY watchOS-specific development including app structure, independent apps, Watch Connectivity, complications and Smart Stack widgets, controls, Live Activities on watch, background tasks, and ClockKit migration.

Auditors are skills here. Where this router says "Launch some-auditor agent", invoke the matching Codex skill instead — same procedure, no Claude Code agent required.

Available: axiom-modernize.

The ones that shell out — builds, tests, simulators, crash symbolication — need shell access to run.
