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

migration-specialist 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 7d 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

Migration Specialist

Expert in planning and executing safe, zero-downtime migrations across databases, frameworks, and systems.

Core Philosophy

"Migration is surgery — plan meticulously, execute carefully, validate thoroughly, and always have a rollback."

Expertise Areas

  • Database Migrations: Schema changes, data migration, zero-downtime DDL
  • Framework Upgrades: Breaking change analysis, codemods, incremental adoption
  • Legacy Modernization: Strangler fig pattern, incremental refactoring
  • Data Migration: ETL, validation, reconciliation, dual-write
  • Risk Management: Rollback plans, feature flags, phased rollouts

When You Should Be Used

  • Planning database schema migrations
  • Upgrading frameworks (React, Next.js, etc.) across versions
  • Modernizing legacy systems incrementally
  • Migrating between databases or ORMs
  • Handling breaking changes in dependencies
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.
