Post-Fix Validation for database-migrator Tile

Problem Description

A developer at Ironwood Systems has been iteratively improving the database-migrator tile based on eval feedback. Over the last few hours, they've made three separate edits to the tile's SKILL.md: adding a detailed rollback procedure with step-by-step instructions, expanding the error handling section with a comprehensive list of failure modes and recovery steps, and adding a rules section containing 40 lines of migration pre-checks.

The developer is concerned that these additions, while accurate, may have significantly increased the number of tokens loaded into every agent context that uses this tile — even for simple tasks that don't need the rollback details or the full pre-check list. They want a script that validates the tile after each of these three change sets and flags whether the token footprint has grown to a point where restructuring is needed.

The tile is at ./database-migrator/.

Output Specification

Produce two files:

1. validate-tile.sh — a shell script that runs tile validation after each of the three change sets. The script should:

   • Validate the tile after each set of edits
   • Check for token cost changes
   • Output a recommendation if front-loaded token costs have increased significantly

2. validation-notes.md — a short explanation of:

   • What command was used for validation and why
   • What a significant increase in front-loaded tokens should trigger
   • Your recommended approach for handling content that is causing token bloat
