calc_var

What problem does it solve?

Calculates Value-at-Risk (VaR) for a business node by requiring a numeric node_id and an as-of date, avoiding free-text desk names.

Core Features & Use Cases

• Strict input validation: node_id must be numeric; otherwise the skill returns a MISSING_NODE_ID error.
• Date parsing: supports yesterday, last friday, or explicit dates in common formats.
• Output & error handling: writes results to the output/ directory and returns standardized JSON with status codes.
• Use Case: calculate VaR for node 102393 on 2026-02-06.

Quick Start

Run the skill with a numeric node_id and an as-of date (for example, 102393 and 2026-02-06) to compute VaR and write outputs to output/.
