name: using-stability-analyzer-ide-plugin
description: Use this skill to install and operate the `skydoves/compose-stability-analyzer` IntelliJ / Android Studio plugin so the developer sees Compose stability feedback live in the editor instead of waiting for a Gradle build. Covers installing the plugin from disk, configuring the `Settings → Tools → Compose Stability Analyzer` panel, reading the four gutter colors (green stable, red unstable, yellow runtime, gray no-params), the per-parameter hover documentation, the inline parameter hint badges, and the `UnstableComposable` weak-warning inspection with its `@Suppress("NonSkippableComposable")` and `@Suppress("ParamsComparedByRef")` quick fixes. Use when the user mentions gutter icons, inline hints, the stability inspection, the IDEA plugin, real-time stability feedback while editing, or asks why a composable is flagged as non-skippable in the editor.

# Using the Stability Analyzer IDE Plugin — live in-editor stability feedback

The Compose Compiler reports tell the developer about stability after a build completes. The `skydoves/compose-stability-analyzer` IntelliJ plugin tells them while they edit. Gutter icons mark every `@Composable` with a color, hover docs render the per-parameter table with reasons, inline hints render colored badges next to each parameter type, and the `UnstableComposable` weak-warning inspection surfaces actionable problems with quick fixes.

The plugin uses the Kotlin K2 Analysis API to evaluate the same stability rules that drive `../understanding-stability-inference/SKILL.md`, so editor feedback agrees with what `../diagnosing-compose-stability/SKILL.md` would later show in the compiler reports. This shortens the loop from "ship → build → read reports" to "type → see the gutter".

## When to use this skill

- The developer wants real-time stability feedback while editing a Composable file.
- A reviewer is reading a PR locally and wants the inline signal next to each composable.
- A new joiner wants to see at a glance which composables in the file are non-skippable.
- The user asks why the editor flagged a function with a weak warning called `UnstableComposable`.
- The user mentions gutter icons, inline hints, the stability inspection, the IDEA plugin, the K2 Analysis API for Compose, or the `Compose Stability Analyzer` tool window.

## When NOT to use this skill

- CI gating that fails the build on stability regressions. Use `../enforcing-stability-in-ci/SKILL.md`.
- Build-time Compose Compiler reports analysis. Use `../diagnosing-compose-stability/SKILL.md`.
- Active runtime tracing or visual cascade investigation through the plugin's tool window. Use `../visualizing-recomposition-cascades/SKILL.md`.
- Conceptual questions about how the compiler classifies a type. Use `../understanding-stability-inference/SKILL.md`.

## Prerequisites

- Android Studio 2024.2+ or IntelliJ IDEA 2024.2+ (build range 242 through 261, covering 2024.2 through the 2026.1 EAP).
- Kotlin 2.3.0 in the IDE plugin runtime, required by the K2 Analysis API the plugin relies on.
- The Compose Compiler Gradle plugin already wired in the project (`org.jetbrains.kotlin.plugin.compose`). The analyzer evaluates stability against the same compiler model.
- The plugin is currently installed from disk during development; the JetBrains Marketplace listing is pending.

## Workflow

### 1. Build the plugin from source

Clone `skydoves/compose-stability-analyzer` and build the IDEA module.

```bash
git clone https://github.com/skydoves/compose-stability-analyzer
cd compose-stability-analyzer
./gradlew :compose-stability-analyzer-idea:buildPlugin
```

The packaged plugin lands at `compose-stability-analyzer-idea/build/distributions/*.zip`.

### 2. Install from disk

In the IDE, open **Settings → Plugins → ⚙ → Install Plugin from Disk...** and pick the ZIP produced in step 1. Restart the IDE when prompted. **DO NOT** look for the plugin in the JetBrains Marketplace yet; the listing is under review at the time of writing.

### 3. Confirm the settings panel

Open **Settings → Tools → Compose Stability Analyzer**. Verify `isStabilityCheckEnabled` is on. The full set of toggles, all read from `StabilitySettingsState`, is:

| Key | Default | Effect |
|---|---|---|
| `isStabilityCheckEnabled` | `true` | Master switch for all editor features. |
| `isStrongSkippingEnabled` | `true` | Match Compose Compiler 2.0.20+ runtime: classify with strong skipping on. |
| `showGutterIcons` | `true` | Render the colored icon in the gutter beside each `@Composable`. |
| `showGutterIconsOnlyForUnskippable` | `false` | Hide green/gray icons; only show problems. Use on dense files. |
| `showGutterIconsInTests` | `false` | Render gutter icons inside test source roots too. |
| `showWarnings` | `true` | Enable the `UnstableComposable` inspection. |
| `showInlineHints` | `true` | Render colored parameter-type badges inline. |
| `showOnlyUnstableHints` | `false` | Suppress inline badges for stable parameters. |
| `stableGutterColorRGB` | `#5FB865` (95, 184, 101) | Gutter / hint color for stable composables. |
| `unstableGutterColorRGB` | `#E8684A` (232, 104, 74) | Gutter / hint color for unstable composables. |
| `runtimeGutterColorRGB` | `#F0C674` (240, 198, 116) | Gutter / hint color for runtime-stability composables. |
| `stableHintColorRGB` / `unstableHintColorRGB` / `runtimeHintColorRGB` | per defaults above | Inline hint color overrides. |
| `ignoredTypePatterns` | `""` | Newline- or comma-separated glob list of types to treat as stable. |
| `stabilityConfigurationPath` | `""` | Optional path to the same `stability_config.conf` the compiler reads. |
| `isHeatmapEnabled` | `tru
