What it does

Flutter Atomic Components is an agent skill from makifbaysal/tasktrooper. Use when adding or reusing Flutter UI - organize widgets as atoms, molecules, and organisms in a shared library and never hand-roll a component that already exists

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Mobile, covering Cross-platform mobile apps. It works with Flutter. The repository describes itself as: Local-first agent platform: board + role agents + agent CLI runs (Claude Code, Cursor, Antigravity, OpenCode) or local and API models (Ollama, LM Studio), all on your own Mac. The licence is Apache-2.0.

When your agent uses it

  • Reusing Flutter UI - organize widgets as atoms
  • Organisms in a shared library and never hand-roll a component that already exists

Example prompts

  • “/flutter-atomic-components”

Workflow steps

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

  1. Check INVENTORY.md / grep atoms → no PriorityBadge, but there is a StatusChip atom. Priority is distinct enough → add a PriorityBadge atom…
  2. Compose it into the TaskCard molecule.
  3. Both the badge atom and the card get a widget test.
  4. Add the PriorityBadge line to INVENTORY.md in the same commit.

What it can do on your machine

Read from SKILL.md and the folder at commit 09f6258. 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 Atomic Components loads about 1.1k tokens when it runs. Until then it costs about 47 tokens; SKILL.md has 544 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~47
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k

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.

Flutter Atomic Components

Overview

The same atomic-design discipline the web app follows applies to Flutter: build a shared component library organized by level and compose screens from it. This keeps the app visually consistent and makes screens small.

Core principle: Reuse before you build. Before writing any button/card/chip/input/list-row, search the component library — hand-rolling a duplicate is a review-blocking defect.

The Levels

LevelWhatFlutter example
AtomSmallest reusable UI, no app logicAppButton, AppTextField, StatusChip, Avatar
MoleculeA few atoms forming a unitTaskCard (title + chip + avatar), SearchBar
OrganismSection built from molecules/atomsTaskList, BoardColumn, AppBarWithActions
ScreenRoute wiring organisms to stateTaskBoardScreen

Library lives under lib/ui/core/{atoms,molecules,organisms} — the official Flutter architecture layout — alongside lib/ui/features/<feature>/ for screen-specific composition; follow the app's existing layout if it differs (e.g. a flat lib/ui/atoms).

INVENTORY.md

lib/ui/core/INVENTORY.md: header One line per component: level · name · purpose · variants, one bullet per component, added in the same commit that creates or meaningfully changes it. Check it before building anything — it's faster than grepping the tree and it's the thing the next task's agent will actually read. If the repo has no component library or theme yet, load mobile-design-system-foundation first.

Rules

  • Before creating a component, check INVENTORY.md / grep the library. If an atom exists, use it. If it almost fits, extend it backward-compatibly — don't fork a near-duplicate.
  • Place new components at the correct level. A button is an atom; a card composed of atoms is a molecule. A "component" that fetches data is not a component — split the presentation out.
  • Atoms take data + callbacks, never talk to services. AppButton({required this.label, required this.onPressed}). State/data flows from the screen down.
  • Atoms carry no outer margin of their own — spacing between atoms is the parent's job (a Row/Column with spacing:, or explicit SizedBox/padding at the call site), so the same atom composes correctly in every context without fighting a built-in margin.
  • Style through the theme (see flutter-widget-architecture) so every instance of an atom looks identical.
  • Changing a shared atom: grep every call site first; keep the change backward-compatible or update all callers in the same task. The build must stay green.

Worked Example

Task: "add a priority badge to task cards." Wrong: add a Container with a colored label inline in TaskCard. Right:

  1. Check INVENTORY.md / grep atoms → no PriorityBadge, but there is a StatusChip atom. Priority is distinct enough → add a PriorityBadge atom next to it, themed the same way.
  2. Compose it into the TaskCard molecule.
  3. Both the badge atom and the card get a widget test.
  4. Add the PriorityBadge line to INVENTORY.md in the same commit.

Now every screen showing a task card gets the badge for free, consistently.

Common Mistakes

  • Inline Container/Text styling that reinvents an existing atom.
  • A component with a network/service call inside → not a component.
  • New component dumped at the wrong level (an organism where an atom belongs).
  • Breaking a shared atom's constructor without updating callers.
  • A new component added to the library with no INVENTORY.md line.
  • An atom with a built-in outer margin, so it looks right in one layout and wrong in the next.

Red Flags

  • Two screens render visually identical buttons built differently.
  • A "widget" imports a repository or http client.
  • Copy-pasted styled Containers across screens.
  • lib/ui/core/ (or the repo's component folder) with no INVENTORY.md.
