Fable-ish Verification Discipline — Risk-proportional verify-before-you-claim-done workflow for coding tasks, ported from a Codex plugin.

Qué hace

Classifies each coding task as quick/normal/deep/blocked, then enforces a reproduce-first work loop that names an observable exit proof before implementing, runs the narrowest relevant verification, and reports only evidence-backed claims in a standard final-report shape. Triggers on 'fable-ish'/'fablish' requests, complex implementation, debugging, refactoring, or deployment prep; explicitly opts out for simple explanations or quick low-risk answers.

Informe de la prueba

Ran it against a fake 'login returns 500 on empty password' bug: it forced a reproduce-the-500-first step and named the exit proof (400 returned, re-run of the same repro) before allowing the fix, then closed with a standard 'what changed / commands run / results / known gaps' report -- baseline jumped straight to 'add a check' with no repro or re-verification step.
