A convenient default can quietly make a choice for people long after the situation has changed.
A familiar report opens with the account that used to be right. No one notices the default has become a decision until the wrong person acts on it.
Ask what choice happens when nobody supplies context
A default feels neutral because it removes a decision from view. In practice it makes a choice for someone whenever the missing context is not supplied.
Use one diagnostic question: What choice does this workflow make when nobody supplies the context? If the answer would change for a real exception, the assumption needs to be visible.
Where AI fits
AI can surface the context a workflow is assuming and draft the exception questions that would make that default unsafe.\n
The human decision
People decide when an exception applies and verify the result. AI may reveal a hidden choice but must not silently substitute another.
The lesson
Defaults are decisions that can outlive the conditions that originally justified them.
The Build Log companion traces a default that pointed at the wrong account and why the relevant context had to become explicit.

Defaults are decisions that can outlive the conditions that originally justified them.
Paste the prompt, share only the context needed to answer it, and treat the result as a draft for your review. Do not include confidential information or let an AI assistant make changes without your approval.
Optional: for a visual report and saved memory, run /dxdev first.

LESSON: 2026-02-27_visible-context
WHAT TO SHARE:
A de-identified workflow step, its default behavior, and examples of situations where the default may not fit.
ASK YOUR AGENT TO:
1. Separate confirmed facts from assumptions and unanswered questions.
2. State the choice the default makes when context is absent.
3. List exceptions that would change the correct choice.
4. Draft the smallest visible context check for a human owner.
RETURN:
An assumed-choice, exception, and owner table for human review.
BOUNDARY: Do not change records, contact anyone, route work, publish content, or act in an external system. A person must review the evidence and approve every consequential step.
