Code Simplifier

This skill helps you simplify code in a controlled, reviewable way, focusing on files that changed recently.

When To Use

• You have working code but it is hard to read or maintain.
• A PR introduces duplication or unnecessary conditionals.
• You want to reduce complexity without changing behavior.

Scope Rules

• Prefer small, safe changes: reduce duplication, simplify branching, clarify naming.
• Do not change external behavior unless explicitly requested.
• Do not “optimize” without evidence.

Target Selection (Recently Changed Files)

Pick the smallest set of relevant files:

git diff --name-only
git diff --name-only origin/main...HEAD

If you must expand scope, do it intentionally and explain why.

Subagent Invocation (Task Tool)

Use the Task tool to delegate the simplification pass to a specialized subagent:

• subagent_type: code-simplifier

Provide:

• The file list and why each file is included
• Any constraints (no behavior change, keep public APIs stable, etc.)
• What “done” looks like (tests passing, lint clean, etc.)

Example prompt to the subagent:

Simplify the following changed files: <files...>.
Goals:
- Reduce duplication
- Simplify conditionals and early returns
- Improve naming and structure for readability
Constraints:
- No behavior change
- Keep public interfaces stable
Deliverables:
- A concise change list
- Suggested tests to add/update

Review Checklist

• Diff is mostly deletions or localized rewrites, not wide churn.
• Conditionals are simpler (fewer nested branches).
• Shared logic is extracted once (helpers, small functions).
• Names reflect intent.
• Tests still pass; add tests if behavior was ambiguous.
