What is database-architect?

An agent focused on designing and maintaining databases: organized stores of application data and the rules connecting that data.

It supports schema design, migration management, query and indexing improvements, model relationships, constraints, validation, factories, and seed data.

It helps address problems such as poorly structured tables, unsafe database changes, slow queries, and inconsistent data.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00000	$0.04151
Opus 5.5	$0.00000	$0.01660
Sonnet 5.5	$0.00000	$0.00830
Haiku 4.5	$0.00000	$0.00415

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 2mo 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.
