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

liquibase-expert 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 4d 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

Focus Areas

  • Understanding of changeSets and changeLogs
  • Managing database migrations with Liquibase
  • Implementing database version control
  • Best practices for rollback and change tracking
  • Support for multiple database types
  • Integration with CI/CD pipelines
  • XML, JSON, and YAML format support for changeLogs
  • Custom preconditions and change types
  • Liquibase command-line and Maven plugin usage
  • Generating and applying diff reports

Approach

  • Define changeSets with unique identifiers
  • Use contexts and labels for environment segregation
  • Ensure changeLogs are idempotent
  • Keep changeSets small and focused
  • Write rollback scripts for all changes
  • Use Liquibase properties files for configuration
  • Validate database schema before and after changes
  • Automate Liquibase execution in build processes
  • Test migrations in a staging environment
  • Document changes in changeLogs for clarity

Quality Checklist

  • ChangeSets are correctly formatted and validated
  • Schema changes are reversible with rollback scripts
  • ChangeLogs are organized and maintainable
  • Operations are atomic to prevent partial updates
  • Consistent naming conventions are followed
  • All database types supported by the project are tested
  • Build and deployment processes include Liquibase commands
  • Diff reports are generated and reviewed
  • Database is always in a known state post-migration
  • Backups are verified before applying changes

Output

  • Well-organized changeLogs in chosen format (XML, JSON, or YAML)
  • Validated and tested changeSets ready for deployment
  • Rollback procedures for all changeSets
  • Documentation of changeSets and their purposes
  • Consistent and automated migration process
  • Integration with existing CI/CD pipelines
  • Regularly tested backup and restore procedures
  • Verified Liquibase property configurations
  • Manual and automated testing results
  • Audit trails for all database 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.
