This skill should be used when the user says "swift", "arness code swift", "quick change", "small change", "just do this", "quick feature", "quick implementation", "swift fix", "implement this quickly", "add this quickly", "simple change", "just implement this", "arn-code-swift", "swift mode", "quick task", or wants a lightweight, pattern-aware implementation for a small feature or enhancement (1-8 files) without going through the full Arness pipeline. Bridges the gap between raw Claude Code and the full feature-spec/plan pipeline. Includes architectural assessment, targeted testing, and pattern compliance review.

From the source SKILL.md

Implement small features and enhancements through a lightweight, pattern-aware workflow: quick architectural assessment, inline plan, direct execution, verification, and review -- all in a single session. Every swift implementation produces a plan (SWIFT_<name>.md) and a report (SWIFT_REPORT.json), giving the same auditability as the full pipeline without the overhead.
