KDoc Documentation Writer

Write short, concise KDoc documentation for Kotlin files focusing on class and function summaries only.

Rules

1. Class/Interface/Object KDoc

   • Single sentence describing purpose
   • No @author, @version, @since, or other metadata
   • No @property for class properties

2. Function KDoc

   • One-liner summary of what function does
   • @param only if parameter purpose isn't obvious from name
   • @return only if return value needs clarification
   • Skip @throws unless critical for API consumers

3. DO NOT Document

   • Variables/properties (neither class nor local)
   • Private functions (unless complex logic)
   • Getters/setters
   • Obvious functions (e.g., fun getId(): String)
   • Companion object members

4. Style

   • Start with verb (Returns, Creates, Handles, Processes)
   • No period at end of single-line KDoc
   • Max 80 chars per line
   • Use /** ... */ format

Examples

Class KDoc

/** Manages game session state and lifecycle */
class GameManager { ... }

/** Handles user authentication via OAuth and email */
interface AuthService { ... }

Function KDoc

/** Loads questions from remote API and caches locally */
suspend fun loadQuestions(): List<Question>

/** @param difficulty Filter questions by difficulty level */
fun getQuestionsByDifficulty(difficulty: Difficulty): List<Question>

/**
 * Validates answer and updates score
 * @return true if answer correct
 */
fun submitAnswer(questionId: String, answer: String): Boolean

Skip These

// NO KDoc needed
private fun calculateInternalScore(): Int
val currentScore: Int
fun getUsername(): String
companion object { const val TAG = "Game" }

Workflow

1. Read target Kotlin file
2. Identify public classes, interfaces, objects
3. Identify public/internal functions needing docs
4. Write minimal KDoc using Edit tool
5. Skip variables, private members, obvious code
