What does this skill validate?

It validates XIRR (Internal Rate of Return) and management fee calculations within specific server analytics files to ensure they match intended behaviors.

How does it handle cash flow signs?

It enforces standard conventions where investments are treated as negative values and distributions as positive values to maintain consistency with truth cases.

Does it support Excel parity?

Yes, it is specifically designed to cross-check calculations against Excel's XIRR() formula using the excelFormula field in JSON truth cases.

Which files does this skill target?

It primarily targets server/analytics/xirr.ts, server/analytics/fees.ts, and their corresponding truth-case documentation in the docs/ directory.

Can I use this for complex fee schedules?

Yes, it supports validating management fees based on committed or called capital, including step-downs and alternative fee basis examples.
