A minimal IntelliJ Platform plugin that surfaces a re-entry briefing when you return to a project after a period of inactivity (default: 3+ days).

1. Opt-in only: The plugin activates only for projects that contain a .keepgoing/meta.json file. If the file is absent, nothing happens.
2. On project open, it reads .keepgoing/state.json and .keepgoing/sessions.json to determine when you last worked on the project.
3. If the inactivity threshold is met (>= 3 days), a notification balloon appears with:
   • Last worked: A human-readable time string (e.g. "5 days ago").
   • Project intent: The high-level goal, if recorded.
   • Next step: The suggested next action from your last session.
   • Open last touched files: A button that opens the files you last edited, using IntelliJ's FileEditorManager.

• JDK 17 or later
• IntelliJ IDEA (Community or Ultimate, 2023.2+)

From the apps/jetbrains-plugin directory:

# Using the Gradle wrapper (recommended once generated)
./gradlew runIde

# Or if you have Gradle installed globally
gradle runIde

This launches a sandboxed instance of IntelliJ IDEA with the plugin installed. Open a project that contains a .keepgoing/ directory to test the notification.

If the wrapper scripts are not present, generate them:

gradle wrapper

./gradlew buildPlugin

The resulting ZIP is placed in build/distributions/.

./gradlew runPluginVerifier

1. Create a test project directory with a .keepgoing/ folder containing:

   .keepgoing/meta.json:

   {
     "projectId": "test-project",
     "createdAt": "2025-01-01T00:00:00Z",
     "lastUpdated": "2025-01-01T00:00:00Z"
   }

   .keepgoing/state.json:

   {
     "lastActivityAt": "2025-01-01T00:00:00Z"
   }

   .keepgoing/sessions.json:

   {
     "version": 1,
     "project": "test-project",
     "sessions": [
       {
         "id": "s1",
         "timestamp": "2025-01-01T00:00:00Z",
         "summary": "Set up initial project",
         "nextStep": "Add unit tests",
         "touchedFiles": ["src/main.kt", "build.gradle.kts"],
         "workspaceRoot": "."
       }
     ]
   }

2. Run ./gradlew runIde and open the test project in the sandboxed IDE.

3. A notification should appear with the re-entry briefing.
