+
+# Elegance
+
+Iteratively study and apply elegant coding patterns. Each iteration: understand the code, research what simple & elegant code looks like, apply learnings, verify with CI.
+
+Run for **3 iterations** (or as specified by the user — can be a number or a duration like `2h`).
+
+## 0. Determine Scope
+
+- Before starting, use the `AskUserQuestion` tool to ask: should this operate on the **whole codebase** or only on **changes in the current branch/PR**?
+- If scoped to current branch/PR, use `git diff main...HEAD` (or the appropriate base branch) to identify changed files and limit all subsequent steps to those files only.
+
+## For each iteration (1 to N)
+
+### 1. Understand
+
+- Read through the relevant source files.
+- Note patterns, repetition, unnecessary complexity, non-idiomatic code.
+
+### 2. Research
+
+- Use WebSearch/WebFetch to research what simple, elegant (yet readable!) code looks like for the relevant technology.
+- Look for idiomatic patterns, standard simplifications, and community best practices.
+- Focus on: simplicity, readability, removing unnecessary abstraction, leveraging language features.
+
+### 3. Apply
+
+- Refactor based on what you learned.
+- This can include: edits, code reorganization, or even rewrites where simplicity demands it.
+- Prefer fewer lines, clearer intent, and idiomatic style.
+- Don't add abstractions — remove them.
+
+### 4. Verify
+
+- Run tests/CI to check edits.
+- If CI fails, fix the issues before proceeding to the next iteration.
+
+### 5. Log Progress
+
+- Briefly note what changed in this iteration and why.
+
+## After all iterations
+
+- Do **not** git commit. Leave all changes in the working directory for the user to review.
+- Present a summary of what changed across all iterations.
+
+## Principles
+
+- **Simple over clever**: Elegant code is simple code.
+- **Readable over terse**: Brevity is good, but not at the cost of clarity.
+- **Idiomatic over generic**: Use the language's strengths. Write TypeScript like TypeScript, not like Java.
+- **Each iteration builds on the last**: Don't undo previous improvements. Deepen them.
