Tessl review results

This skill was reviewed live with tessl/[email protected].

• Initial score: 95%
• Validation: passed with no errors or warnings
• Main finding: multi-step/data-touching flows lacked explicit validation or verification checkpoints
• After tessl review fix --threshold 100 --yes --json: 100%

The fix specifically addressed the reviewer feedback by adding verification checkpoints to:

• Slow query diagnosis: verify plan changed / stats gathered before AWR
• Migration planning: verify data integrity before cutover
• Agent-safe schema change: verify the change applied cleanly before migration guidance
