SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Refactors become risky and hard to review when they’re too large, bundled with unrelated changes, or undertaken without sufficient test coverage to confirm behavior hasn’t drifted.

Core Features & Use Cases

  • Stepwise refactor planning: Break the reorganization into small, individually-verifiable increments that compile and pass tests.
  • Blast-radius mapping: Identify every caller affected by symbol moves/renames/contract changes to avoid surprise coupling.
  • Test-coverage gating and rollback planning: Start by confirming or adding characterisation tests, identify the riskiest step to execute last, and define rollback strategy per-step or for the overall refactor.

Quick Start

Ask an AI to produce a refactor plan for moving a module and renaming public symbols, including blast radius, test coverage status, sequential mechanical edits, and a rollback strategy.

FAQPage Schema
How do I plan a code refactor to reduce review and integration risk?

Plan a code refactor by breaking the reorganization into small, individually-verifiable increments that compile and pass tests. This stepwise approach ensures each mechanical edit is isolated, reducing overall integration risk.

What is blast radius mapping when renaming or moving public symbols?

Blast radius mapping identifies every caller affected by symbol moves, renames, or API contract changes. Mapping these dependencies before any edits begin prevents unexpected coupling and runtime failures during code reorganization.

How do you ensure behavior doesn't drift during a module reorganization?

Ensure behavior remains stable during module reorganization by confirming existing test coverage or inserting characterisation tests. These tests gate the refactor, verifying that sequential mechanical edits do not alter original functionality.

What is the best way to define a rollback strategy for incremental refactoring steps?

Define a rollback strategy for incremental refactoring by evaluating the risk of each step, executing the riskiest step last, and establishing per-step or overall rollback boundaries to safely reverse code reorganization if verification fails.

When do I need to establish explicit out-of-scope boundaries for a refactoring task?

Establish explicit out-of-scope boundaries for a refactoring task when changes are too large or bundled with unrelated modifications. Defining these boundaries prevents scope creep and keeps the mechanical edit sequencing focused and verifiable.
