What it does

Flutter Feature Based Clean Architecture is an agent skill from HoangNguyen0403/agent-skills-standard. Organize Flutter apps with modular feature-based clean architecture. Use when creating features under lib/features/ with domain, data, and presentation layers. Do not use for test-only, BlocBuilder, navigation, or spinner requests.

Its SKILL.md is about 660 tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including reference files (for example `evals/evals.json`, `references/REFERENCE.md` and `references/folder-structure.md`).

It sits in Mobile, covering Cross-platform mobile apps and Design patterns. It works with Flutter. The repository describes itself as: A collection of Agent Skills Standard and Best Practice for Programming Languages, Frameworks that help our AI Agent follow best practies on frameworks and programming laguages. The licence is MIT.

When your agent uses it

  • Creating features under lib/features/ with domain
  • Presentation layers
  • Spinner requests

Example prompts

  • “/flutter-feature-based-clean-architecture”

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. Create feature directory — Add new folder under lib/features/ (e.g., lib/features/promotions/).
  2. Define domain layer — Add entities, failures, and repository interfaces with zero external dependencies.
  3. Implement data layer — Add DTOs, data sources, and repository implementations that depend only on Domain.
  4. Build presentation layer — Add BLoC/Cubit, pages, and widgets that depend only on Domain.
  5. Enforce dependency rule — Presentation -> Domain <- Data. Domain must zero external dependencies.
  6. Share cross-cutting logic — Move reusable utilities to lib/shared/ or lib/core/.

What it can do on your machine

Read from SKILL.md and the folder at commit b529c2d. 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

    No scripts in the folder and no shell commands in SKILL.md.

    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

Flutter Feature Based Clean Architecture loads about 663 tokens when it runs, and up to ~1.3k if it reads all its reference files. Until then it costs about 68 tokens; SKILL.md has 235 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~68
When it runs · the whole SKILL.md, loaded when a task matches
~663
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.3k

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.

description
Organize Flutter apps with modular feature-based clean architecture. Use when creating features under lib/features/ with domain, data, and presentation layers. Do not use for test-only, BlocBuilder, navigation, or spinner requests.

Feature-Based Clean Architecture

Priority: P0 (CRITICAL)

Structure

Every feature lives in lib/features/ with 3-layer separation (domain/data/presentation):

  • domain/ — Entities, failures, and Repository interfaces.
  • data/ — DTOs, DataSource, and Repository implementations.
  • presentation/ — BLoC/Cubit, pages, and widgets.

See references/folder-structure.md for complete directory blueprint.

Implementation Workflow

  1. Create feature directory — Add new folder under lib/features/ (e.g., lib/features/promotions/).
  2. Define domain layer — Add entities, failures, and repository interfaces with zero external dependencies.
  3. Implement data layer — Add DTOs, data sources, and repository implementations that depend only on Domain.
  4. Build presentation layer — Add BLoC/Cubit, pages, and widgets that depend only on Domain.
  5. Enforce dependency rule — Presentation -> Domain <- Data. Domain must zero external dependencies.
  6. Share cross-cutting logic — Move reusable utilities to lib/shared/ or lib/core/.
Feature Directory Example

See implementation examples for full directory tree and cross-feature import patterns.

Reference & Examples

For feature folder blueprints and cross-layer dependency templates: See references/REFERENCE.md.

Anti-Patterns

  • No Cross-Feature Data Imports: Only import Domain types across features
  • No UI/Data in Domain Layer: Never put UI or Data classes inside domain/
  • No Nested Features: Keep lib/features/ flat with no sub-feature directories
  • No Direct Repository Calls: Use specific BLoCs or use-cases instead of calling other features' repositories directly from UI
