code-simplifier

name	code-simplifier
description	Simplify recently-changed code without changing behavior. Use only when explicitly invoked (e.g. "simplify", "clean up", "refactor").

Scope: only files changed in the current session or git diff against the base branch. Do not wander into unrelated code.

Before:

• Run the test suite. If it's red before you start, stop and report.
• Read AGENTS.md / CONTRIBUTING.md / nearby code. Match existing conventions, don't import outside ones.

Rules:

• Preserve behavior exactly. No API, signature, or output changes.
• One concern per pass (rename OR extract OR flatten — not all three).
• Don't touch tests unless the user asked.
• Don't reorder imports.
• Don't add abstractions. Remove them when they have one caller.
• Prefer statements over nested expressions (no nested ternaries, no clever chains).
• Delete comments that restate the code. Comments should explain why, not what. This includes comments that just paraphrase the signature or make tautological claims.
• Stdlib over a dependency. Don't add a require/import of a new package to save three lines.
• Don't expose things that don't need to be exposed, default should be private.
• Clear up repeated code if possible.
• Use DRY when it makes sense, even if it means touch code that was already there

After:

• Run the tests again. They must still pass.
• If the diff grew past ~50 lines or crossed unrelated files, stop and surface it before continuing.
• Never commit. Leave staging and the commit message to the human.
• Make sure any repository linters pass.
