SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve? Business-logic specifications often leave boundary conditions, exception paths, and state-transition behavior to implicit AI completion, producing unconfirmed assumptions that surface as defects during implementation. ## Core Features & Use Cases - Systematic Constraint Derivation: Enumerates branches, calculations, transitions, approvals, and control rules, then assigns LCD-prefixed identifiers to each derived requirement confirmation gate. - State-Transition Matrices: Expands transition matrices wherever the design exposes current-state and action axes, keeping invalid transitions and boundary calculations explicit. - Structured Output: Writes a grouped derivation basis table and unresolved confirmation list to a dated Markdown file under work/constraint_derivation/. - Use Case: Given a flowchart and calculation rules for an approval workflow, derive every structurally implied branch and boundary case into a reviewable confirmation list before development begins. ## Quick Start Derive requirement confirmation gates from the attached business-logic specification and write the LCD table to the default output path.

Frequently Asked Questions about logic_constraint_derivation

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I derive requirements from business logic specifications?▼

Provide logic specs, flowcharts, calculation rules, or state-transition definitions as input. The skill enumerates branches, calculations, transitions, and approvals, assigns LCD-prefixed IDs, and writes a grouped confirmation list to a Markdown file.

What is a state-transition matrix in requirements derivation?▼

A state-transition matrix maps current states against possible actions to expose every valid and invalid transition. The skill expands these matrices whenever the design exposes current-state and action axes, making unconfirmed transitions explicit.

Where does the constraint derivation output get written?▼

By default the result is written to work/constraint_derivation/ with a date-prefixed filename like YYYY-MM-DD_logic_constraint_derivation_<topic>.md. You can specify a different output path explicitly.

Can this skill infer missing else-paths or exception behavior?▼

No. The skill deliberately does not infer unspecified else-paths or guess business rules from happy-path examples. Unresolved branches, invalid values, and boundary behavior are kept explicit as open confirmation items.

When should I stop a logic constraint derivation run?▼

Stop if invalid transitions or boundary calculations are being skipped, or if a single happy-path example is being accepted as full logic coverage. The monitoring rules require preserving the difference between confirmed rules and unconfirmed cases.
