Make this practical

Work through each step by writing and testing actual code. Never accept an agent or model output without running the tests and checking the diff.

1
Define concrete inputs, outputs, and constraints before touching the keyboard.
Hint: Specify error handling and edge cases up front.
Check: Clear definition of done established.
2
Build the minimal viable core and verify with real data.
Hint: Avoid premature abstraction; get a working pipeline first.
Check: End-to-end flow verified.
3
Write automated checks and tests to guard against regressions.
Hint: Test the failure paths, not just the happy path.
Check: Automated verification passing.
4
Audit the implementation with Second Opinion before shipping to production.
Hint: Check for unhandled exceptions, hardcoded credentials, and missing bounds.
Check: Zero critical audit findings.
