The goal is to never break cross-file references and never guess at what is affected.</p>\n<h2>When to Use</h2>\n<ul>\n<li>Renaming a class, function, method, variable, or file</li>\n<li>Extracting a function or method</li>\n<li>Restructuring a module or splitting a file</li>\n<li>Changing a function signature</li>\n<li>Any change that touches more than one call site</li>\n</ul>\n<h2>Refactoring Workflow</h2>\n<h3>1. Assess before touching anything</h3>\n<pre><code>assess_change_risk({ file_path: \"src/foo.ts\" })\n# or\nassess_change_risk({ symbol_id: \"&lt;id&gt;\" })\n</code></pre>\n<p>This returns the risk level of the target change based on churn, complexity, fan-in/fan-out, and test coverage. Use it to decide whether to proceed, add tests first, or split the change.</p>\n<h3>2. Find what actually needs refactoring</h3>\n<pre><code>get_refactor_candidates()\n</code></pre>\n<p>Do not guess. This surfaces high-complexity, high-churn, and anti-pattern-laden symbols that are the real refactor targets.</p>\n<h3>3. Know what will break</h3>\n<pre><code>get_change_impact({ symbol_id: \"&lt;id&gt;\" })\n</code></pre>\n<p>Returns the reverse-dependency graph: every file, symbol, and test that depends on the target. Review this list before editing.</p>\n<h3>4. Quantify complexity</h3>\n<pre><code>get_complexity_report({ file_path: \"src/foo.ts\" })\n</code></pre>\n<p>Gives you a baseline so you can verify the refactor actually reduced complexity.</p>\n<h2>Renaming a Symbol — MANDATORY Flow</h2>\n<p><strong>Never</strong> rename with <code>Edit</code> and <code>replace_all</code>. It silently misses import sites, re-exports, type references, and cross-file usages.</p>\n<pre><code># 1. Collision detection first\ncheck_rename({ symbol_id: \"&lt;id&gt;\", target_name: \"newName\" })\n\n# 2. Apply rename across ALL files (definition + every reference)\napply_rename({ symbol_id: \"&lt;id&gt;\", new_name: \"newName\" })\n</code></pre>\n<p><code>apply_rename</code> updates the definition, imports, re-exports, call sites, JSX usages, and tests in one atomic operation.</p>\n<h2>Extracting a Function</h2>\n<pre><code>extract_function({\n  file_path: \"src/foo.ts\",\n  start_line: 42,\n  end_line: 67,\n  new_name: \"computeTotals\"\n})\n</code></pre>\n<p>Let trace-mcp handle the variable capture analysis — manual extraction routinely misses closure variables.</p>\n<h2>After the Refactor</h2>\n<ol>\n<li><code>register_edit</code> on each edited file to reindex</li>\n<li><code>get_complexity_report</code> again to confirm the reduction</li>\n<li><code>get_tests_for</code> the changed symbols — run them</li>\n<li><code>check_quality_gates</code> with <code>scope: \"changed\"</code> to verify no regressions</li>\n</ol>\n","files":[{"path":"SKILL.md","sizeBytes":2695,"isText":true}],"reviewScore":null,"reviewSummary":null,"trust":{"provenance":"trusted-source-unreviewed","notice":"Community-authored content, reproduced verbatim and not vetted as instructions.
