Shortcuts that “do nothing” usually hide preventable failures: intent resolution misses, missing prompts, or long work killed silently — make them diagnosable, not mysterious

Shortcuts that “do nothing” usually hide preventable failures: intent resolution misses, missing prompts, or long work killed silently — make them diagnosable, not mysterious.

Define AppIntent inputs with @Parameter and concrete types (Date, enum) and add XCTest round-trip checks for archived shortcut metadata where feasible.
Keep perform() short: return a quick acknowledgement and hand off heavy work to background workers with idempotency keys and retry policies.
Surface localized, actionable error messages and gate permission-flow changes behind feature flags so support can anticipate new prompts.
Consider instrumenting entry/exit and I/O boundaries with OSSignposter and structured logging, and include correlation IDs so traces can be stitched across services.

Choose typed parameters when the input shape is stable; choose freeform String when user intent is genuinely ambiguous.

How have you handled migration of legacy shortcut identifiers in production, and which debugging signals (logs, signposts, telemetry) proved most useful?
