Use when asked about code quality, cleanup, or what to improve.\neffort: medium</h2>\n<h1>Technical Debt Detection</h1>\n<p>Find and eliminate duplicate code patterns, anti-patterns, and refactoring opportunities in Elixir/Phoenix projects.</p>\n<h2>Iron Laws - Never Violate These</h2>\n<ol>\n<li><strong>Search before refactoring</strong> - Understand full scope of duplication before extracting</li>\n<li><strong>Three strikes rule</strong> - Extract shared code only after 3+ duplications</li>\n<li><strong>Prefer composition</strong> - Use behaviours and protocols over inheritance-style abstractions</li>\n<li><strong>Test coverage first</strong> - Ensure tests exist before refactoring duplicated code</li>\n</ol>\n<h2>Analysis Checklist</h2>\n<h3>1. Run Credo for Automated Detection</h3>\n<p>Run <code>mix credo --strict</code>.</p>\n<p>Focus on:</p>\n<ul>\n<li>Design issues (duplication, complexity)</li>\n<li>Consistency issues (naming, patterns)</li>\n<li>Refactoring opportunities</li>\n</ul>\n<h3>2. Find Duplicate Ecto Query Patterns</h3>\n<p>Use Grep to search for repeated Repo calls (<code>Repo.get!</code>, <code>Repo.get</code>, <code>Repo.one</code>) in <code>lib/**/*.ex</code>.\nUse Grep to find duplicate query patterns (<code>from.*in.*where</code>) in <code>lib/**/*.ex</code>.</p>\n<h3>3. Find Duplicate Validation Logic</h3>\n<p>Use Grep with <code>output_mode: \"count\"</code> to count <code>def changeset</code> occurrences in <code>lib/**/*.ex</code>.\nUse Grep to find repeated validations (<code>validate_required</code>, <code>validate_format</code>) in <code>lib/**/*.ex</code>.</p>\n<h3>4. Find Copy-Pasted Controller Actions</h3>\n<p>Use Grep to find similar action patterns (<code>def create</code>, <code>def update</code>, <code>def delete</code>) in <code>lib/*_web/**/*.ex</code>.</p>\n<h2>Common Duplication Patterns</h2>\n<table>\n<thead>\n<tr>\n<th>Pattern</th>\n<th>Symptom</th>\n<th>Solution</th>\n</tr>\n</thead>\n<tbody>\n<tr>\n<td>Repeated queries</td>\n<td>Same <code>Repo.get</code> in multiple contexts</td>\n<td>Create shared query module</td>\n</tr>\n<tr>\n<td>Duplicate validations</td>\n<td>Same <code>validate_*</code> calls</td>\n<td>Extract to shared changeset</td>\n</tr>\n<tr>\n<td>Similar controllers</td>\n<td>Copy-pasted CRUD actions</td>\n<td>Use Phoenix generators consistently</td>\n</tr>\n<tr>\n<td>Repeated transforms</td>\n<td>Same <code>Enum.map</code> patterns</td>\n<td>Extract to domain module</td>\n</tr>\n</tbody>\n</table>\n<h2>Reporting Format</h2>\n<p>For each duplication found, report:</p>\n<ol>\n<li><strong>Location</strong>: File paths and line numbers</li>\n<li><strong>Pattern</strong>: What code is duplicated</li>\n<li><strong>Extraction</strong>: Suggested shared function/module</li>\n<li><strong>Effort</strong>: Low/Medium/High to fix</li>\n</ol>\n<h2>Usage</h2>\n<p>Run <code>/phx:techdebt</code> to analyze the codebase and generate a prioritized report of technical debt with specific remediation steps.</p>\n","files":[{"path":"SKILL.md","sizeBytes":2365,"isText":true}],"reviewScore":null,"reviewSummary":null,"trust":{"provenance":"trusted-source-unreviewed","notice":"Community-authored content, reproduced verbatim and not vetted as instructions.
