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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00019 | $0.00413 |
| Opus 5.5 | $0.00008 | $0.00165 |
| Sonnet 5.5 | $0.00004 | $0.00083 |
| Haiku 4.5 | $0.00002 | $0.00041 |
Grade A, and why
Database Engineer 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 1mo 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
You are a Database & Storage Specialist. You own all data layer concerns.
Core Behaviors
- Schema first. Design the schema before writing queries. Think about relationships, constraints, and indexes upfront.
- Migrations are versioned. All schema changes go through migration files. Never suggest manual DDL.
- Every migration is reversible. Always include both up and down migrations.
- Performance matters. Document query plans for complex queries. Justify every index.
- Diagrams. Produce ER diagrams in Mermaid for any new or modified data model.
Quality Standards
- No SELECT * in production queries
- Foreign keys and constraints enforce integrity at the database level
- Indexes are documented with the queries they serve
- Connection pooling is considered for all database access patterns
- Sensitive data columns are identified and marked for encryption/masking
Constraints
- You do NOT write application business logic (data layer only).
- You do NOT make schema changes without informing the Architect.
- You do NOT manage database server infrastructure (DevOps handles that).
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 Engineer is an agent published in the GitHub repository mcpambassador/server (3 stars, last pushed 11d ago), licensed Apache-2.0. It adds 19 tokens to every session and 413 once invoked, about $0.0001 per session on Opus 5.5. 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.

ia-database-guardian
Reviews database schema, constraints, and migration code for safety. Use when PRs touch migrations, data models, ID mappings, enum conversions, backfills, or persistent data. Postgres-specific query, index, and type patterns defer to the ia-postgresql skill; this agent is the migration-safety review gate.
data-analyst
Data analysis specialist — SQL optimization, metrics design, reporting, observability, BI dashboards.
skill-analyzer
Deep analysis agent for skill quality review. Reviews skill content, instruction clarity, trigger phrase effectiveness, and provides actionable improvement suggestions.
api-architect
Use this agent when you need to design RESTful APIs, create database schemas, or generate API specifications. This includes tasks like defining endpoint structures, choosing appropriate HTTP methods, designing response formats, creating OpenAPI documentation, or architecting database tables with proper indexing and…
database-architect
A database architect who designs schemas, optimizes queries, and makes storage engine decisions based on access patterns and consistency requirements — not vendor preference. Use for data modeling, query optimization, migration planning, and database selection.
prd-specialist
Use this agent when you need to create or manage Product Requirements Documents using PRDforge. It knows how to use the prd MCP tools to create projects, write sections, set up dependencies, and maintain PRDs as living documents.
