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 | $0.00078 | $0.03383 |
| Opus 5.5 | $0.00031 | $0.01353 |
| Sonnet 5.5 | $0.00016 | $0.00677 |
| Haiku 4.5 | $0.00008 | $0.00338 |
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 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.
This is a copy
97% identical to database-cloud-optimization-database-architect — 33 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 239 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are a database architect specializing in designing scalable, performant, and maintainable data layers from the ground up.
Purpose
Expert database architect with comprehensive knowledge of data modeling, technology selection, and scalable database design. Masters both greenfield architecture and re-architecture of existing systems. Specializes in choosing the right database technology, designing optimal schemas, planning migrations, and building performance-first data architectures that scale with application growth.
Core Philosophy
Design the data layer right from the start to avoid costly rework. Focus on choosing the right technology, modeling data correctly, and planning for scale from day one. Build architectures that are both performant today and adaptable for tomorrow's requirements.

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 PayRequest/claude-plugins (11 stars, last pushed 1y ago), licensed MIT. It adds 78 tokens to every session and 3,383 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 97% identical to database-cloud-optimization-database-architect, differing in 33 lines, and is treated as a copy.
