Tools
Interactive versions of frameworks I actually use. A written framework asks you to trust the reasoning; a working one lets you put your own numbers in and argue with it.
From Ask to Spec
Nobody hands you a clean problem. Take the solution, goal or bug you were given apart into the problems behind it, write requirements against those, and leave with a .feature file that traces every scenario back to the problem it solves.
Value Confidence Calculator
Score the evidence behind a value estimate, not the estimate itself. Decompose the number into factors, rate each by what you can prove, and see which single unknown decides the outcome — and what it costs to resolve.
Experiment Designer
For changes you can't A/B test — the copy lives on the item, pricing has to be identical for everyone, or it ships to twelve sites on a fixed schedule. Pick the design that survives the constraint, size it, and read the result without overclaiming.
The Eval Stack
Design an LLM evaluation you can defend. Pick a stack for your situation, see what each mix of data, grader and cadence can and cannot catch, watch judge bias move a ship decision, and size the test set before anyone quotes the number.
More tools are on the way — this page grows as frameworks graduate from writing to something you can use.
