# Task ID: 37

**Title:** Add priority, summary, chapters, and linkTarget fields to Prompt schema

**Status:** done

**Dependencies:** None

**Priority:** high

**Description:** Extend the Prisma schema for the Prompt model to include priority (integer 1-10, default 5), summary (nullable string), chapters (nullable JSON array), and linkTarget (nullable string for prompt links).

**Details:**

1. Update `/src/db/prisma/schema.prisma` to add fields to the Prompt model:
   - `priority Int @default(5)` with check constraint 1-10
   - `summary String? @db.Text`
   - `chapters Json?` (stored as JSON array of strings)
   - `linkTarget String?` (format: `project/server:resource-uri`)

2. Create Prisma migration:
   ```bash
   pnpm --filter db exec prisma migrate dev --name add-prompt-priority-summary-chapters-link
   ```

3. Update TypeScript types in shared package to reflect new fields

4. Add validation for priority range (1-10) at the database level if possible, otherwise enforce in application layer

**Test Strategy:**

- Unit test: Verify migration creates columns with correct types and defaults
- Unit test: Verify priority default is 5
- Unit test: Verify nullable fields accept null
- Unit test: Verify chapters stores/retrieves JSON arrays correctly
- Integration test: Create prompt with all new fields, retrieve and verify values
