Claude skills files

SUMMARY

Adds a set of project skills under .claude/skills/ plus CLAUDE.md project guidance. No runtime/app code is touched — this is tooling for working in the repo.

What's included

• run-observe-propose-verify — a disciplined debug loop (Run → Observe → Propose → Verify) with an explicit can't-reproduce branch and a verify-fails loop-back, tuned to this repo's manual-verification workflow.

• rigorous-mathematician — a mathematically rigorous accounting/finance persona for deriving, reviewing, and auditing the calculators' financial math (derive from first principles, cross-check against an amortization schedule, probe boundary cases).

• new-calculator — scaffolds a new app/interactives//page.tsx following the established self-contained pattern from the time-value-money reference (typed constants, CONSTRAINTS, FieldError[] validation, string-based inputs, dark-mode tokens, aria).

• calculator-qa — a manual QA checklist (boundaries, currency input, validation, dark mode, accessibility, basePath/iframe), since the repo has no automated test suite.

• CLAUDE.md — project guidance for Claude Code.

NOTES

• Skills auto-surface via their description triggers, or can be invoked explicitly (/new-calculator, etc.). They only shape how Claude behaves in-session — they don't add build/deploy automation.
• The skills cross-reference each other (e.g. new-calculator and calculator-qa defer to rigorous-accountant for the math).
