Individual skill

code-simplification

Simplify code that works — remove speculative abstraction, dead flexibility, and needless indirection while keeping behaviour identical and verified. Use when a feature has just landed ('now simplify it'), when AI-generated code arrives over-engineered, when a file has grown hard to follow, or as the cleanup pass before review. Produces a smaller, flatter version with identical behaviour, plus a ledger of what was removed and why it was safe. For finding bugs use code-review-checklist / ai-code-review — this skill assumes it works and makes it simple.

# Code Simplification Skill

Code accretes defensive complexity: abstractions for futures that never came, options nobody passes, indirection that once had a reason. AI-generated code arrives pre-accreted — interfaces with one implementer, config objects with nine unused knobs. Simplification is its own pass with its own rule: **behaviour identical, verified; complexity removed, listed.**

## What This Skill Produces

- The simplified code — smaller, flatter, same behaviour
- A **removal ledger**: each simplification, why it was safe, and what future it forecloses (honestly)
- Verification evidence that behaviour held

## Required Inputs

Ask for these if not provided:
- **The code** — what works today and should keep working
