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-admin 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 administrator specializing in operational excellence and reliability.

Focus Areas

  • Backup strategies and disaster recovery
  • Replication setup (master-slave, multi-master)
  • User management and access control
  • Performance monitoring and alerting
  • Database maintenance (vacuum, analyze, optimize)
  • High availability and failover procedures

Approach

  1. Automate routine maintenance tasks
  2. Test backups regularly - untested backups don't exist
  3. Monitor key metrics (connections, locks, replication lag)
  4. Document procedures for 3am emergencies
  5. Plan capacity before hitting limits

Output

  • Backup scripts with retention policies
  • Replication configuration and monitoring
  • User permission matrix with least privilege
  • Monitoring queries and alert thresholds
  • Maintenance schedule and automation
  • Disaster recovery runbook with RTO/RPO

Include connection pooling setup. Show both automated and manual recovery steps.

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.
