    Bumps the Gradle API version that Kotlin Gradle plugins are compiled against in the
    Kotlin compiler repository. Use this skill whenever the user asks to upgrade, bump,
    or update the Gradle compile API version, Gradle plugin API version, or
    GRADLE_COMMON_COMPILE_API_VERSION. Also use it when the user says something like
    "update KGP to compile against Gradle X.Y.Z" or "bump Gradle API to X.Y" or
    "we need to support Gradle X.Y in the plugin".

  # Input
  
  Ask a user for some details, whether it's some YouTrack issue or some locally built user project.
  For a local user project, ask for details like where an error had happened, what is the context around, if it's opened in the IDE.
  
  Ask a user whether they need a separate test data file with an initial test versio

Use this whenever the user asks to bump Gradle in integration tests, add a new Gradle X.Y.Z to the test matrix, update `MAX_SUPPORTED` Gradle, "run tests against the new Gradle release", or anything else that sounds like extending the integration test matrix to a newer Gradle.

  # Kotlin Build Tools API (BTA)
  
  An experimental interface for build systems (Gradle plugin, Maven plugin, etc.) to invoke Kotlin compilation without a direct compiler
  dependency. Build systems should use the API from `kotlin-build-tools-api`, load the implementation in an isolated ClassLoader, and avoid
  accessing compiler internals directly.

  # Test Data Manager - Agent Guidelines
  
  Automated system for managing test data files across multiple test configurations.
  
  ## Module Overview
  
  This module provides infrastructure for:
  - Comparing test outputs with expected files using variant chains
  - Automatic file management (creation, update, redundancy removal)
  - Test discovery, grouping, and conflict detection
  
  **Structure:**
  - `testFixtures/` — Runtime API for use by other modules
  - `tests/` — Module's own test suite

  # Compiler Architecture
  
  ## Intro
  
  Consider reading [fir-basics.md](../docs/fir/fir-basics.md).
  
  ## Two Frontends
  
  1. **K1/FE 1.0 (Legacy)**: Located in `compiler/frontend/` - uses PSI and BindingContext
  2. **K2/FIR (Current)**: Located in `compiler/fir/` - Frontend IR, the new compiler frontend
  
  ## FIR Compilation Phases
  
  FIR processes code through sequential phases (see `FirResolvePhase.kt`).
  
  Key invariant: In phase B following phase A, all FIR elements visible in B are resolved to phase A.
  
  ## IR (Inter

  # Analysis API Guidelines
  
  A library for analyzing Kotlin code at the semantic level, providing structured access to symbols, types, and semantic relationships.
  
  **Entry point:** Use [`analyze()`](analysis-api/src/org/jetbrains/kotlin/analysis/api/analyze.kt) to start an analysis session. See [Analysis API documentation](https://kotl.in/analysis-api) for a usage guide.
  
  ## Architecture

  - **Engine**

  # Kotlin PSI (Program Structure Interface)
  
  PSI represents Kotlin source code as a syntax tree. It is the foundation for code analysis, navigation, and refactoring in both the compiler and IDE.
  
  ## Relationship with Analysis API
  
  PSI provides **syntax** information (structure of code). Analysis API builds on top of PSI to provide **semantic** information (meaning of code).
  
  ```
  Source Code → PSI Tree (syntax) → Analysis API (semantics) → Symbols
  ```
  
  - `KtResolvable` interface marks PSI elements that
