What it does

Uikit UI Common Setup is an agent skill from drawthingsai/draw-things-community. Use when writing or refactoring UIKit UI in this repo, especially Workflow/ViewController wiring, Controller/View components, SnapKit layout, Workspace/Dflat-driven UI state, Objective-C adapter responders, or app threading boundaries.

Its SKILL.md is about 950 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).

It sits in Mobile, covering iOS development. It works with Objective-C. The repository describes itself as: The community repository for the Draw Things app. The licence is GPL-3.0.

When your agent uses it

  • Refactoring UIKit UI in this repo
  • Especially Workflow/ViewController wiring
  • Controller/View components
  • Workspace/Dflat-driven UI state

Example prompts

  • “/uikit-ui-common-setup”

What it can do on your machine

Read from SKILL.md and the folder at commit 3cac075. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • rg

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Uikit UI Common Setup loads about 953 tokens when it runs. Until then it costs about 64 tokens; SKILL.md has 468 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~64
When it runs · the whole SKILL.md, loaded when a task matches
~953

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

UIKit UI Common Setup

First Pass

  • Read nearby app code before introducing a new shape.
  • Prefer existing Draw Things / Local Code UIKit patterns over new abstractions.
  • Use rg / rg --files to find matching Workflow, ViewController, and Controller examples.

Workflow And ViewController

  • UI screens are managed by Workflow objects.
  • A Workflow owns the concrete UIViewController.
  • Expose viewController when the workflow needs the concrete type, and viewControllable as the generic UIKit-facing UIViewController.
  • UIViewController subclasses are views plus UIKit event handling only.
  • Do not put business logic, persistence policy, generation logic, networking, model work, or off-main-thread work in a UIViewController.
  • UIViewController sends events out through delegates. The Workflow handles them and sets properties back on the view controller.

Controller And View

  • For shared business logic outside a workflow, use Controller & View.
  • A controller is a plain Swift class, not NSObject and not a UIKit subclass.
  • It owns one root UIView property, usually let view: UIView.
  • Controllers are usually owned by workflows. Letting a view controller own one is only for lightweight, mostly animation-focused cases.

Layout And View Setup

  • Use lazy vars for referenced views. Each lazy var configures that view and self-contained subviews.
  • Put hierarchy assembly and cross-view SnapKit constraints inline in viewDidLoad or the controller initializer.
  • In viewDidLoad or the controller initializer, do layout first, then action/delegate hookups.
  • Do not create one-off configureXXX / setupXXX methods for view setup, layout, or action wiring.
  • Domain helpers are fine when they express behavior or reusable construction, such as makeProjectMenu, updateSettingsSections, or didTapCollapseOrExpand.

One-Way Dataflow

  • Persisted UI state should flow from Dflat / Workspace / workspace.dictionary observations into UI properties.
  • Delegate callbacks should write source-of-truth state or call workflow/controller behavior, not directly mutate unrelated UI state.
  • Even didSet-driven UI updates should be reached through the owning Workflow or real Controller when the state is not purely local view presentation.
  • Keep view controllers as render targets: set properties on them; let them update UIKit controls.

Objective-C And UIKit Adapters

  • A UIViewController already inherits from NSObject; using it for UIKit lifecycle/delegates is fine.
  • Plain controllers must stay plain Swift classes.
  • When a plain controller needs Objective-C delegation, target/action, or UIKit delegate conformance, create a nested responder such as Controller.ObjCResponder: NSObject.
  • The responder forwards callbacks back to the controller; it does not own business logic.

Threads And Queues

  • Do not use async / await in app UI code.
  • UIViewController subclasses and views should only touch main-thread UIKit state.
  • Workflow and Controller objects are the right places for off-main-thread behavior.
  • Avoid creating private queues per workflow/controller. Reuse existing shared queues when behavior fits.
  • Prefer one or two shared queues for broad work classes, like Draw Things' edit queue handling generation, tokenization, and related work.
  • Create a new queue only when the behavior truly needs a separate serialization or QoS boundary. For rare fire-and-forget work, a global concurrent queue can be acceptable.
