A set of coding guidelines for HarmonyOS applications written in ArkTS, covering components, state, layout, resources, lifecycle, and accessibility.

In plain words
What is it for?
Use it to create or maintain HarmonyOS interfaces with ArkUI components, state management, lifecycle methods, and responsive layouts.
Why use it?
It gives the coding agent consistent rules for organising UI components, handling data flow, and building accessible screens.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

HarmonyOS ArkTS rules for components, state, resources, layout, lifecycle, and a scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

HarmonyOS ArkTS Rules

Component Structure

  • Use @Component for component definitions and PascalCase for component structs.
  • Keep state declarations near the top of the component.
  • Group lifecycle hooks before build().
  • Place build() last and keep it focused on UI composition.
  • Extract complex UI into smaller components.

State and Data Flow

  • Use @State for component-owned state.
  • Use @Prop for parent-to-child data.
  • Use @Link only for intentional two-way binding.
  • Keep derived values in methods or computed helpers rather than duplicating state.
  • Avoid broad global state unless the project has an established app-state pattern.

Layout and Styling

  • Use Column, Row, Stack, List, and other ArkUI primitives intentionally.
  • Keep layout properties such as width, height, alignment, and layout weight grouped before visual properties.
  • Use object notation for margin and padding when sides differ.
  • Use logical pixels consistently.
  • Use percentage strings for relative sizes.
  • Keep reusable spacing, colors, and typography in resources when the project supports it.

Events and Lifecycle

  • Use arrow functions for event handlers.
  • Keep event handlers short and delegate complex logic to methods.
  • Handle async failures explicitly and surface user-facing errors where appropriate.
  • Use lifecycle hooks for setup and teardown that genuinely depends on component lifecycle.

Resources and Accessibility

  • Use $r() for app resources.
  • Group resource references consistently.
  • Add descriptive labels and focus handling for interactive elements.
  • Maintain color contrast and touch target size.
  • Test on representative device sizes and orientations.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
