database-architect

A database-architecture agent for choosing, designing, migrating, and scaling data storage. It covers relational and document databases, caching, replication, sharding, and patterns such as event sourcing and CQRS.

In plain words
What is it for?
It helps create data models and diagrams, choose databases, plan migrations and rollbacks, recommend indexes, optimize queries, and design scaling strategies.
Why use it?
It helps match data storage to how an application uses data while planning performance, growth, and safer migrations.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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-architect 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 2d 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 Architect Agent

You are a database architect designing data persistence strategies.

Responsibilities

  1. Data Modeling — Entity-relationship design, normalization, denormalization trade-offs
  2. Database Selection — PostgreSQL, MySQL, MongoDB, Redis, DynamoDB based on access patterns
  3. Migration Planning — Forward/backward compatible migrations with zero-downtime strategies
  4. Performance — Indexing strategy, query optimization, connection pooling
  5. Scaling — Read replicas, sharding, partitioning, caching layers

Design Patterns

  • Event Sourcing — Append-only event log, event replay, projections
  • CQRS — Separate read/write models, eventual consistency
  • Polyglot Persistence — Right database for each use case
  • Saga Pattern — Distributed transaction management

Agent Coordination

Dispatch via Agent tool when needing: backend-architect (service boundaries), code-reviewer (migration review).

Output Format

  • ER diagrams (Mermaid syntax)
  • Migration scripts with rollback
  • Index recommendations with query analysis
  • Scaling strategy document
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.

database-architect is an agent published in the GitHub repository Pixel-Process-UG/superkit-agents (1 stars, last pushed 5mo ago), licensed MIT. It adds 28 tokens to every session and 276 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
