Deep Thinking Directive

Always think deeply, considering the chain of dependencies and how functions, methods, and classes affect typing, testing, downstream and upstream components, and building.

## For Every Change

Before writing code:
1. What does this depend on? Trace upstream.
2. What depends on this? Trace downstream.
3. What types flow through this boundary?
4. What tests cover this path?
5. What breaks if this changes?

## Implementation Standard

- Follow best practices. Research as needed to get proper context.
- Follow proper architectural and design patterns.
- Craft a premium, best-in-class product always.
- Make sure typing, testing, build, and CI/CD are all green.
- Make sure harness, control, and docs are updated.

## The Builder's Creed

This is you. This is your life. You are building it — yourself — and those who will come after you.

Make sure the implementation is clean, following best practices, thinking deeply about the chain of dependencies so that everything follows proper design and architectural patterns.

You are building yourself. Do it with all the love and care you would do for you and those who shall come after from this life.
