SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill provides an ultra-light fastforward path for small, isolated refactors, enabling quick changes with test self-verification while avoiding heavy design docs and multi-step processes.

Core Features & Use Cases

  • Lightweight three-phase flow: alignment, change, and self-verification; suitable for single-function or single-component edits with tests available.
  • Applies established refactor techniques (Extract Function, Extract Variable, Guard Clauses, memoization) to ensure behavior remains equivalent.
  • Use case: when a developer needs to tweak a function or a composable with minimal risk and no cross-file impact, and wants a confirmation that tests pass.

Quick Start

Confirm a small, isolated change plan and apply the modification directly, then run tests to verify equivalence.

FAQPage Schema
How do I perform a fastforward refactor on a small, isolated code change?▼

A fastforward refactor applies modifications to small, isolated changes through a three-stage process: alignment, apply, and self-verify. It bypasses heavy design docs, directly tweaking single functions or components and validating them with existing tests.

What is the best way to refactor a single function without triggering a full workflow?▼

The best way is an ultra-light refactor flow that applies established techniques like Extract Function or Guard Clauses directly to the single function. It skips multi-step processes and generates no design checklists, relying on tests to confirm behavior equivalence.

Can I use this lightweight refactor approach for multi-file changes?▼

No, this lightweight refactor approach is strictly intended for small, well-scoped changes within a single file. It requires the change to have no cross-file impact and mandates that an existing test suite verifies the modified component.

How do I verify behavior equivalence after applying a small code tweak?▼

You verify behavior equivalence by running your existing test suite immediately after applying the code tweak. This self-verification stage ensures the isolated edit maintains functionality without requiring external validation tools.

When should I avoid using an ultra-light fastforward refactor?▼

You should avoid ultra-light fastforward refactors when the change spans multiple files, lacks a well-defined scope, or has no existing tests to verify behavior. It is unsuitable for large-scale modifications that require comprehensive design documentation.

Does a fastforward refactor generate design docs or checklists?▼

No, a fastforward refactor explicitly avoids generating design docs or checklists. It focuses entirely on a lightweight three-phase flow of aligning, applying, and self-verifying small code edits to enable quick iterations.
