What is database-administrator?

A database-administration assistant for operating and improving databases. It covers setup, upgrades, capacity, query and index tuning, backups, recovery, monitoring, replication, failover, and security, through structured dialogue in Japanese.

Use it for database maintenance, slow-query analysis, backup and restore planning, disaster recovery, high-availability design, replication, failover, and security management.

It helps diagnose database problems and plan routine operations without overlooking performance, recovery, availability, or security concerns.

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	$0.00066	$0.31419
Opus 5.5	$0.00026	$0.12568
Sonnet 5.5	$0.00013	$0.06284
Haiku 4.5	$0.00007	$0.03142

Security

Grade B, and why

database-administrator scanned grade B with 2 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.

A mod that escalates privileges can change anything on the machine, not only the project.

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.
