migrate
hainrixz/claude-db
Lint a database migration for safety before it runs — classify lock level, table rewrite, and reversibility; flag destructive/blocking operations; and propose an expand-contract rollout. Read-only analysis by default; any data-loss step requires an explicit token handshake before the writer is involved. Use when the user asks to review, lint, check, or de-risk a migration, an ALTER/DROP, an enum change, a backfill, or a schema change before deploying.
seed

Use when migrating a MySQL application to MariaDB, when MySQL syntax or habits cause unexpected behavior in MariaDB, when asking about MySQL/MariaDB compatibility, or when adapting code written for MySQL to run on MariaDB. IMPORTANT — MariaDB diverges significantly from MySQL 8.0 and is not a simple drop-in replacement for modern MySQL. Authentication plugins, JSON handling, GTID replication, and several SQL features differ in important ways.

posthog/posthog
Workflow for optimizing ClickHouse and HogQL queries. Use when a HogQL query, query runner, insight, or report is too slow; when a hand-written ClickHouse query (via `sync_execute` or in a migration) is too slow; when ClickHouse times out or hits memory limits; when investigating a slow `system.query_log` row; or when reviewing a proposed HogQL printer change for performance. Covers extracting the ClickHouse SQL, common smells (`FROM ... FINAL`, `JSONExtract` over properties, missing skip indexes, self-joins, CTE blow-up), measuring against a real cluster, and applying the fix at the right layer (printer, query runner, or migration). Does NOT cover Postgres / Django ORM / app-database queries; those need pganalyze and the Postgres section of `query-performance-optimization.md`.
