Provides the complete Swift Concurrency Migration Guide. Use when migrating to Swift 6, resolving data-race safety errors, understanding Sendable and actor isolation, or incrementally adopting async/await.

Provides the complete content of 'The Swift Programming Language (6.4 beta)' book by Apple. Use this skill when you need to verify Swift syntax, look up language features, understand concurrency, resolve compiler errors, or consult the formal language reference.

Produces prose that reads as authentically human by avoiding statistical patterns common to LLM output. Use when writing or editing prose, documentation, READMEs, PR descriptions, or any text where the output must not read like AI-generated content.

Create a fully standalone escalation brief that hands a problem to a stronger model, senior engineer, teammate, maintainer, or outside expert with no repo access and no conversation history. Two modes: diagnosis (agent is stuck, repeated fixes have failed, root cause is unclear) and judgment (design/architecture/UI critique, plan validation, 'get a second opinion,' 'have the best problem-solver weigh in'). Produces a self-contained packet with goal, embedded code/config/evidence, attempts or alternatives considered, constraints, prioritized questions with decision forks, and a response-format contract, plus guidance for applying the expert's answer.
