TASK BRIEFS
A request with room for interpretation
“Add filtering” sounds simple. Decide what it really means before the first edit.

THE PRACTICE LAB
Good judgment takes practice.
Make decisions, see the consequences, and try an unfamiliar situation.
NEW · PROMPT DECISIONS
One task. Four ways to ask.
Pick the best prompt, compare every tradeoff, and repair a weaker choice in your own words.
Try prompt decisionsNEW · EVIDENCE PRACTICE
Predict, investigate, then return.
Predict a tool result, find a weak verification claim, and revisit the skill in unfamiliar scenarios.
Open evidence practiceRealistic situations. Safe space.

REPOSITORY CONTEXT
The README says one thing…
Find the real test command when the documentation and package manifest disagree.

VERIFICATION
Green tests. Broken confidence.
A bug fix has passing tests. The diff tells a different story.
