The Code Simplifier Agent — Clarity After the Feature Lands

A feature that works is not the same as a feature that is easy to maintain. The Code Simplifier agent runs after implementation, looking at what just changed and asking a narrower question: can this be clearer without doing anything different?

The scope is deliberately tight. The agent does not audit the whole codebase — it focuses on code touched in the current session. This keeps the review fast and keeps it from wandering into parts of the project that are not under discussion.

What it does

The agent goes through recently modified code and applies refinements in a few specific categories. Unnecessary nesting gets flattened. Redundant abstractions — a wrapper that does nothing except call through — get removed. Variable and function names that describe the mechanism rather than the intent get renamed. Comments that just restate the code in English get deleted.

One firm rule: no nested ternary operators. When a condition branches into three or more paths, the agent rewrites it as a switch or an if-else chain, because the branching structure becomes visible instead of collapsed into a single dense expression. Brevity that costs readability is not a simplification.

Functionality is never touched. The refactored code must behave identically to what it replaced — every output, every side effect, every error path. The agent applies the project's own coding standards, not a generic style, which means the result fits the rest of the file rather than introducing a new convention.

One concrete example

A developer adds a function to format a user's display name. The first pass works: it handles nulls, trims whitespace, falls back to an email prefix. But it does this in a nested ternary three levels deep. The Code Simplifier rewrites it as three clearly sequenced checks, each on its own line with a named variable for the intermediate result. The output of the function does not change — the logic is now easy to read at a glance.

Where it sits

The Code Simplifier is invoked during /dr-compliance, the hardening stage that follows QA, where the compliance step calls it to tidy recent code. It also runs on demand when clarity issues are spotted outside the compliance cycle. Because its scope is bounded to recent changes, it fits naturally between implementation and archiving — a final pass that catches what the developer was too close to the problem to notice.
