Claim Audit
Connect a claim to its decision, evidence source, tested context, exclusions, counterevidence and residual uncertainty, then produce a defensible claim draft.
DO LESS. PROVE MORE.
Make fewer claims.
Prove the ones that matter.
Complex technical work often fails the credibility test not because teams do too little, but because they claim too much. Do Less. Prove More. is a practical field guide to setting proof boundaries, defining evidence obligations and reducing residual uncertainty before a decision depends on the work.
THE BOOK
From activity to defensible evidence.
This book is for senior engineers, architects, AI/ML practitioners, technical product and program leaders and technology executives who need to make consequential decisions without pretending uncertainty has disappeared.
Its central idea is simple: every meaningful claim creates a proof obligation. The job is not to create the appearance of completeness. The job is to define what is being claimed, test what matters and state what remains unknown.
FIELD TOOLS
Turn proof discipline into working decisions.
All tools run locally in your browser and require no account. They are designed to expose proof obligations and decision boundaries rather than manufacture certainty or hide judgment behind a single score.
Test Sufficiency Check
Assess whether the evidence covers the decision-relevant scenarios, failure modes, environment, reproducibility and untested scope.
AI Evaluation Scope Builder
Frame model version, intended task, evaluation population, metrics, thresholds, comparators, exclusions and what the evaluation actually establishes.
Proof Boundary Canvas
Separate proven conditions, unproven conditions, explicit exclusions and residual uncertainty around a decision.
Proof Discipline Check
Review claim precision, traceability, boundary discipline, reproducibility, uncertainty disclosure and decision fit by dimension.
Evidence Ladder
Classify available evidence by strength and determine what additional evidence would materially change the decision.
Residual Uncertainty Register
Capture what remains unknown, consequence if wrong, relevance to the present decision and the next evidence action.
Claim Chain Inspector
Break a conclusion into linked claims and test whether each inferential jump has an explicit basis.

THE COMPANION BOOK
Leading outcomes is the other half of the problem.
The Outcome Leader focuses on turning strategy into measurable outcomes through clarity, decision rights, mobilization and evidence.
