What it does

Kmp Starter Feature Database is an agent skill from DevAtrii/Kmp-Starter-Template. The KMP Starter Template Room database — entities, DAOs, migrations, and DB configuration in features/database. How to add tables and bump versions safely.

Its SKILL.md is about 810 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 Development, covering Project scaffolding. 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.

When your agent uses it

Tasks that involve Project scaffolding

Example prompts

“/kmp-starter-feature-database”

Workflow steps

3 steps, taken from the step headings in SKILL.md.

Configure the database
Add a table
Migrations

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 (its code samples are kotlin).
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 Feature Database loads about 806 tokens when it runs. Until then it costs about 46 tokens; SKILL.md has 149 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~46
When it runs · the whole SKILL.md, loaded when a task matches: ~806

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: The KMP Starter Template Room database — entities, DAOs, migrations, and DB configuration in features/database. How to add tables and bump versions safely.
author: DevAtrii
license: MIT

Database (Room)

Room Database for local storage with multiplatform support. Entities, DAOs, migrations. Single module: features/database.

Where things live

Piece	Path
`KmpStarterDatabase` (abstract Room db)	`features/database/src/commonMain/.../KmpStarterDatabase.kt`
`KmpStarterDatabaseMigrations`	`features/database/src/commonMain/.../KmpStarterDatabaseMigrations.kt`
`getKmpDatabase` (builder)	`features/database/src/commonMain/.../DatabaseProvider.kt`
DI	`features/database/src/commonMain/.../di/DatabaseModule.kt`
`KmpStarterDatabaseConstructor`	platform `expect`/`actual` (Android/iOS)

1. Configure the database

KmpStarterDatabase defines the DB name and version:

kotlin

@Database(
    entities = [SampleEntity::class],
    version = KmpStarterDatabase.DB_VERSION,
    exportSchema = false,
)
@ConstructedBy(KmpStarterDatabaseConstructor::class)
abstract class KmpStarterDatabase : RoomDatabase() {
    companion object {
        const val DB_NAME = "kmp_starter.db"
        const val DB_VERSION = 1   // increment on any schema change
    }
    abstract fun myDao(): MyDao
}

The builder (getKmpDatabase) wires migrations, driver, and IO context:

kotlin

fun getKmpDatabase(...): KmpStarterDatabase {
    val builder = ...
    return builder
        .addMigrations(*KmpStarterDatabaseMigrations.SUPPORTED_MIGRATIONS)
        .setDriver(BundledSQLiteDriver())
        .setQueryCoroutineContext(Dispatchers.IO)
        .build()
}

2. Add a table

Entity — one class per table:

kotlin

@Entity
data class SampleEntity(
    @PrimaryKey(autoGenerate = true)
    val id: Int = 0,
    val value: String,
)

DAO — queries, inserts, updates, deletes:

kotlin

@Dao
interface MyDao {
    @Query("SELECT * FROM sample_entity")
    fun getAll(): Flow<List<SampleEntity>>

    @Insert(onConflict = OnConflictStrategy.REPLACE)
    suspend fun insert(sampleEntity: SampleEntity): Long
}

Register in @Database(entities = [...]) and expose the DAO via an abstract fun.

3. Migrations

When the schema changes, add a Migration and append it to SUPPORTED_MIGRATIONS (never mutate an existing migration — add a new one):

kotlin

object KmpStarterDatabaseMigrations {
    private val MIGRATION_1_2 = object : Migration(1, 2) {
        override fun migrate(connection: SQLiteConnection) {
            connection.execSQL("ALTER TABLE notes ADD COLUMN tags TEXT")
        }
    }
    val SUPPORTED_MIGRATIONS: Array<out Migration> = arrayOf(MIGRATION_1_2)
}

Then bump DB_VERSION to match the migration's end version.

Rules

Always increment DB_VERSION when adding columns/tables; add a matching migration.
Use TypeConverters for non-primitive fields (lists, custom objects).
Register databaseModule in InitKoin (see koin skill).
