# Registry Authoring and Addresses
Use this reference when the user wants to create, fix, publish, or reason about
a shadcn registry.
## Mental Model
A registry has two forms:
- **Source registry**: an authored `registry.json` in a project or repository.
It may use `include` and file paths that point at source fi... | openai-build-week | .agents/skills/shadcn/registry.md | Markdown | 4a004b108e4e298a8d30d0350d483b7057647da5b4f07d3094f9da862fa26497 | 0 | 896 |
{
"brand": "oklch(0.72 0.16 250)"
}
}
}
```
Important fields:
- `name`: the installable item name. It is not necessarily a file path.
- `type`: one of the registry item types, such as `registry:ui`,
`registry:block`, `registry:lib`, `registry:hook`, `registry:file`,
`registry:page`, `registry:theme`, ... | openai-build-week | .agents/skills/shadcn/registry.md | Markdown | ef243973461564fd7c58cbdffb2d806e89dcb280f0821b772907de8707915ce1 | 1 | 896 |
acme/ui/data/schema.json` is treated as a file path, not a
GitHub item address.
## GitHub Registries
A public GitHub repository can act as a source registry when it has a root
`registry.json`.

## Key Fields
The injected project context contains these key fields:

. These won't match the project's actual aliases. Use `npx shadcn@latest info` to get the correct `ui` alias (e.g. `@workspace/ui/components`) and rewrite the imports accordingly. The CLI rewrites imports for its own UI files, but third-party registry components may use default paths that don't match the project.

# Actors
Use this when:
- You need to protect class-based mutable state from concurrent access.
- You are choosing between `actor`, `@MainActor`, `nonisolated`, or `Mutex`.
- You are resolving protocol conformance issues on actor-isolated types.

**: This pattern keeps the `non-Sendable` value alive and accessible within the `Task`. The `Task` runs on the caller's isolation domain, so no cross-isolation "sending" occurs.

# AsyncAlgorithms Package
Use this when:
- You need time-based operators (debounce, throttle, timers).
- You need to combine multiple async sequences (merge, combineLatest, zip).
- You are migrating from Combine or RxSwift operators to Swift Concurrency equivalents.
Skip this file if:
- You need basic `AsyncStream`... | openai-build-week | .agents/skills/swift-concurrency/references/async-algorithms.md | Markdown | 45c3c98f8dd35d77de70a7fbb941ac308dbea021d859ca3d4700883835ad97d4 | 0 | 896 |

Emit at most one value per interval. Use for repeated actions like button taps.

AsyncSequence with backpressure. **Stable operator ✅**
Use for producer-consumer patterns with flow control.

)`.
- **Looking for a `.flatMap` equivalent**: Use `TaskGroup` for fan-out; the semantics differ from Combine/Rx `flatMap`.
- **Looking for `.receive(on:)` equivalent**: Use `@MainActor` or `Task` context for isolation instead.

# "Dependencies Aren't Ready"
Options:
- Update to latest versions first
- Use `@preconcurrency` temporarily
- Contribute fixes to open-source dependencies
- Wrap third-party APIs in your own concurrency-safe layer
### "I Keep Going in Circles"
This is the "concurrency rabbit hole":
- Take breaks and revisit later

# Performance
Use this when:
- Async code is slower than expected or causing UI hangs.
- You need to choose between synchronous, asynchronous, and parallel execution.
- You are profiling concurrency overhead with Instruments.

- The issue is a compiler diagnostic about isolation or Sendable. Use `... | openai-build-week | .agents/skills/swift-concurrency/references/performance.md | Markdown | ac4c881fb0a6550bab8bd79172b36222bf82c0260db797832a1fe5d84b88316e | 0 | 896 |
not suspend.
### Suspension surface area
Code between suspension points. Larger = harder to reason about:
- Actor invariants
- Performance
- Thread hops
- Reentrancy
- State consistency
### Goal
- Do work before crossing isolation
- Cross once
- Finish job
- Only cross again when necessary

. **Name tasks** - easier debugging in Instruments
5. **Check suspension count** - reduce unnecessary awaits
6. **Avoid premature parallelism** - has costs
7. **Consider UX** - smooth > fast

# Sendable
Use this when:
- A value or reference type must cross an isolation boundary safely.
- You are resolving "non-Sendable type" compiler diagnostics.
- You need to decide between value types, `@unchecked Sendable`, actors, or region-based isolation.
