🔁 Model Migration Checker

by JustHandled Labs

$6/mo

Find the model-version coupling that breaks when you swap LLMs. Flags hardcoded model names and versions, deprecated or renamed parameters (the max_tokens to max_completion_tokens class of change), hardcoded token and context-window limits, response-format parsing tied to one model's output, tool-schema format coupling between providers, and hardcoded per-token cost constants. The patterns load from an editable model-rules table you update as new models ship.

Classic to Block Theme Migrator

by Arnstein Larsen

$22.99

Database Schema & Query Review Gate

by PubsProToolkit

$12

Review a database schema, queries, or migration for the mistakes that get expensive in production — bad table design, missing or wrong indexes, slow and N+1 queries, SQL injection, and migrations that lock or break prod. Engine-aware (PostgreSQL, MySQL, SQLite, SQL Server), it runs an ordered review and returns a PASS/REVIEW/BLOCK verdict with prioritized fixes. Schema mistakes are the most expensive kind — this catches them before they ship.

Cut observability cost 60-80%. Migrate Datadog/New Relic to Prometheus + Grafana + Loki. Cost calc, dashboard converter, runbook.

Pull Request Description Writer

by PubsProToolkit

$9

Turn a diff into a structured pull request description — what changed and why, guidance on where to review and what's risky, honest testing notes, and migration/rollback notes. Scaled to the size of the change, so review is faster and the merge is safer.
