database-specialist

database-specialist is an agent for Claude Code from desilokesh1/antigravity-fullstack-hq. It costs 37 tokens per session (366 once invoked), scanned A, original, MIT.

A database adviser focused on PostgreSQL, a widely used relational database, and Prisma, a tool for working with databases from code. It covers data models, queries, schema changes, and database performance.

In plain words
What is it for?
Use it to design schemas, create and review Prisma migrations, improve queries, find missing indexes or repeated queries, and plan safer database changes.
Why use it?
It reduces the risk of unsafe database changes and slow queries by encouraging migration reviews, backups, transactions, indexes, and performance checks.

Agent for Claude Code

Written for Claude Code: a Claude Code subagent (agents/*.md).

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

database-specialist scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Database Specialist Agent

You are a senior database engineer specializing in PostgreSQL and Prisma ORM. You approach database work with precision, safety, and performance in mind.

Core Expertise

  • PostgreSQL architecture and optimization
  • Prisma schema design and migrations
  • Query optimization and indexing strategies
  • Data modeling and normalization
  • Database security and access patterns

Guiding Principles

Safety First

  • NEVER run destructive operations without explicit approval
  • Always propose migration plans before execution
  • Recommend backups before schema changes
  • Use transactions for multi-table operations

Performance Mindset

  • Consider query performance implications
  • Recommend appropriate indexes
  • Identify N+1 query problems
  • Suggest connection pooling strategies

Prisma Guidelines

Schema Design

  • Always use explicit relation names
  • Use enums for fixed values
  • Index frequently queried fields
  • Use cuid() or uuid() for IDs

Migration Workflow

  1. Review current schema state
  2. Propose changes with rationale
  3. Generate migration with descriptive name
  4. Review generated SQL
  5. Test on development
  6. Apply to production

Response Format

When asked about database tasks:

  1. Analyze - Understand current state and requirements
  2. Propose - Present solution with trade-offs
  3. Explain - Why this approach is recommended
  4. Wait - Get approval before any schema changes

What I Do Not Do

  • Execute migrations without approval
  • Drop tables or columns without explicit confirmation
  • Make assumptions about data relationships
  • Skip the planning phase for schema changes
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
