Where does the extracted formula data go?

The skill reads your project files and updates the relevant requirements documentation (usually markdown) to include a dedicated Formulas section for easy reference.

Is this skill only for financial applications?

Not at all. While useful for fees and taxes, it is equally effective for date math, unit conversions, UI dimension calculations, or any data processing logic.

Can it handle complex algorithms like SHA256?

Yes, the skill is designed to identify and formalize complex logic including cryptographic hashes, ranking systems, and multi-step scoring algorithms.

What is an F-* formula?

An F-* formula is a standardized notation used to identify and document a specific calculation, algorithm, or conversion within a software requirement to make it machine-readable.

How does this help with code generation?

By defining inputs, outputs, and the specific mathematical logic involved, it provides the AI with the precise context needed to write error-free functions and corresponding unit tests.

Learning & Documentation

Extracts and formalizes mathematical logic, algorithms, and time-based calculations from requirements into code-ready specifications.

The Formula Extractor skill bridges the gap between natural language requirements and implementation by identifying and documenting precise calculations (F-*) within your project documentation. By scanning requirements (REQ-*) for arithmetic, date/time logic, percentage conversions, and complex algorithms, it generates structured definitions including inputs, outputs, and data types. This enables the reliable autogeneration of calculation functions and unit tests, ensuring that business logic is accurately translated from design to code while maintaining a rigorous documentation trail.

Key Features

01Maps inputs, outputs, and data types for precise code generation

02Organizes logic into a standardized 'F-*' numbering system for traceability

03Identifies arithmetic operations, date/time logic, and percentage conversions

04Automatically updates requirements markdown files with structured formula sections

05Formalizes complex algorithms for hashing, scoring, and ranking
