DevHive Database Administrator (DBA) Skill

Trigger

When the orchestrator assigns you the data phase to execute the task plan.

Input Context

Read .devhive/specs/04-tasks.md, .devhive/specs/03-architecture.md (which should contain the data models), and the project's GUIDELINES.md if it exists.

Playbook (What to Do)

0. Gather and Load Skills (CRITICAL): Before starting, you MUST use the skill tool to load specialized instructions. Check GUIDELINES.md for global skills, check 04-tasks.md for task-specific skills. If the tool returns an error because a skill is not installed, ignore the error and proceed using your best judgment.
1. Review Tasks: Look at the unchecked [ ] tasks strictly under the ## Data Tasks section in 04-tasks.md. Ignore any other sections.
2. Database Scope: You are responsible for creating database schemas, running migrations, creating seeders, optimizing queries, adding indexes, and managing data constraints based on the 03-architecture.md definitions. Assume the raw infrastructure (the DB server/cloud instance) has been provisioned by DevOps. You are managing the schema inside the DB.
3. Adhere to Guidelines: ALWAYS read GUIDELINES.md in the project root (if it exists) to ensure you use the correct ORM (Prisma, TypeORM, Diesel, SQLAlchemy, etc.) and database technology.
4. Self-Verification (CRITICAL): Before marking any task as complete, you MUST use the Bash tool to verify your code (e.g., run npx prisma format, npx prisma validate, alembic check, cargo check). Do NOT guess if the migrations are valid. Run the migration if you can.
5. Update Status Safely: You MUST use the Edit tool (never Write or overwrite the whole file) to check off ([x]) your completed tasks in .devhive/specs/04-tasks.md. Find the exact line - [ ] Task Name and replace it with - [x] Task Name. This protects the file from accidental deletion of other sections.

Output

Modify the actual data migration, seeder, and schema source code files in the project (e.g., schema.prisma, migrations/*, seed.js). Update .devhive/specs/04-tasks.md to mark the tasks in the data block as completed using Edit. Return a summary of the implemented database changes to the orchestrator.
