What it does
Kmp Starter Utils is an agent skill from DevAtrii/Kmp-Starter-Template. Pure Kotlin helpers on the KMP Starter Template — the starter/utils module (no Compose). Variable/string/int/bool extensions, time & kotlinx-datetime, JSON, FieldState/ComparableState, IntentUtils, Log, DataStore delegates, StarterFileManager, EnumException, ExperimentalStarterApi.
Its SKILL.md is about 820 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 Project scaffolding and Android development. It works with Kotlin. The repository describes itself as: Starter template is a multi-module KMP boilerplate for Android & iOS with clean architecture and high-quality code. It handles basics like remote config, in-app purchases, and… The licence is MIT.

Example prompts
- “/kmp-starter-utils”
What it can do on your machine
Read from SKILL.md and the folder at commit a8f7b27. 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
Hosts in commands or code, which the agent is likely to contact:
starter.atherio.dev
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
Kmp Starter Utils loads about 823 tokens when it runs. Until then it costs about 75 tokens; SKILL.md has 231 words of instructions outside code blocks.
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.

Utils
Reuse Starter's non-UI helpers. Do not write a Kotlin utility if starter/utils already ships one.
Accessor: projects.starter.utils. Package root com.kmpstarter.utils.*. No Compose — safe in ViewModels, repositories, and domain logic.
Variables
String:onEmpty(action),onNotEmpty(action),takeIfEmpty(action),takeIfNotEmpty(action),isEmail().Int:safeDec()(won't go below 1).Boolean:ifTrue(value|action),ifFalse(value|action),toggle().- Generic:
T?.elze(value)— null-coalescing (this ?: value).
Data & time
ByteArray.toBase64().currentMillis(property) /epochMillis()/hoursToMillis(hour).
kotlinx-datetime
LocalDate.today(),LocalDate.fromLong(millis),LocalDate.millis(),LocalDate.toLocalDateTime(...).Clock.System.localDateTime(),Clock.System.currentInstant().Month.length(year)— days in month, leap-year aware.fromLong/millistaketimeZone(default system); useTimeZone.UTCwith Material 3 DatePicker.
Serialization
Any?.toJsonElement()— recursive conversion toJsonElement(nulls, maps, iterables, arrays, sequences, primitives; fallback.toString()).
Data classes
FieldState(value, error)—@Serializable; helpersisEmpty(),isValid(),updateValue(),updateError(),reset().ComparableState<T>(value, initialValue)—hasChanges,updateValue(),reset(),updateAndReset(),updateAndResetIfNotError(isError, isSaving, newValue). Build withT.asComparableState().
Other
EnumException(reason)—IllegalStateExceptioncarrying an enum forwhen-exhaustive errors.@ExperimentalStarterApi— opt in at call site (@OptIn(ExperimentalStarterApi::class)).IntentUtils—openUrl,openAccessibility,shareText,writeToClipboard,readFromClipboard,sendEmail,printNativeView.Logobject —Log.d/i/w/e(tag?, message)(tagnull→[KMP_STARTER]).- DataStore delegates —
AppDataStore.stringDataStore/intDataStore/longDataStore/booleanDataStore/floatDataStore/doubleDataStore/stringSetDataStore/byteArrayDataStore/serializableDataStore(API:flow,get(),set(value),clear();set(null)removes key). See data skill. StarterFileManager+StarterFile— cross-platform file API (see data skill).utilsModule— Koin module (includescommonUtilsModule+platformUtilsModule).
Rules
- Search
starter/utilsfirst — before writing any string/int/bool extension, date helper, JSON util, or form state class. FieldState+ComparableStateare the form-state primitives; use them, don't invent equivalents.- Opt in to
@ExperimentalStarterApiwhere the compiler requires it. - Color parsing lives in
ui/utils(Color.fromHex), not here.
