aktual: Skill for Claude Code

.claude/skills/new-list-screen/SKILL.md

new-list-screen is a skill for Claude Code from jonapoul/aktual. It costs 48 tokens per session (4,016 once invoked), scanned A, original, Apache-2.0.

A template for creating a mobile app feature with a view model and a scrolling list screen. It covers loading, empty, failure, and successful states, plus refresh behavior and navigation setup.

In plain words
What is it for?
Use it to create a new Android-style list feature in Gradle modules, such as schedules, rules, or other collections of items.
Why use it?
It gives developers a repeatable structure for adding list-based screens without deciding each UI and module pattern from scratch.

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

new-list-screen 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 yesterday.

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.

How it starts

The opening of the file, as written. The whole thing — 565 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Generate a pair of VM and UI Gradle modules for a new scrolling list screen, following the exact patterns from aktual-budget:schedules.

Before starting — ask one question

Ask the user: "Is this feature budget-scoped? (i.e. does it live inside an open budget, using BudgetNavEntryContributor / BudgetNavScope / BudgetNavKey?)"

Wait for the answer, then proceed. Use {budgetScoped} = true or false to select the correct NavEntryContributor template in Step 2 below.

Arguments

$ARGUMENTS contains two space-separated values:

  • FeatureName — PascalCase singular name for the feature, e.g. Rules
  • GradleModulePath — colon-separated path without a leading colon, e.g. aktual-budget:rules

Derived values

Given FeatureName = Rules and GradleModulePath = aktual-budget:rules:

Variable Derivation Example
{Name} FeatureName as-is Rules
{name} FeatureName lowercased rules
{dir} GradleModulePath with :/ aktual-budget/rules
{pkg} GradleModulePath with :. and -. aktual.budget.rules
{vmGradle} :{GradleModulePath}:vm :aktual-budget:rules:vm
{uiGradle} :{GradleModulePath}:ui :aktual-budget:rules:ui
{snakeTitle} list_{name}_title list_rules_title

The List{Name} prefix (e.g. ListRules) is used for all list-specific classes.

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.
