Source files match above 1000 LOC; test files use a relaxed 2000 LOC discovery threshold.</p>\n<h2>Arguments</h2>\n<ul>\n<li><code>path</code>: Optional file or directory to scan. Default: current working directory.</li>\n<li><code>--include-generated</code>: Include generated, vendored, dependency, and build-output paths that are skipped by default.</li>\n</ul>\n<h2>Workflow</h2>\n<ol>\n<li><p>Resolve the skill directory, then run the helper from the target repository:</p>\n<pre><code>uv run \"&lt;skill-dir&gt;/scripts/large-file-refactor.py\" [path] [--include-generated]\n</code></pre>\n</li>\n<li><p>Preserve the helper's Markdown table as the exhaustive report. Do not omit matching rows, even when the refactor plan\nonly covers a subset.</p>\n</li>\n<li><p>If the helper reports no threshold matches, stop after the report. A match is a candidate, not proof that the file\nshould be split.</p>\n</li>\n<li><p>Draft a refactor plan for the 3 largest files only, unless the user explicitly requested another count.</p>\n</li>\n<li><p>For each candidate, rank split value by mixed responsibilities, change frequency/risk, coupling, and testability. Use\nwhichever semantic symbol/reference tooling is available; prefer Serena when installed:</p>\n<ul>\n<li>Inspect symbol overviews, references, imports, and relevant history.</li>\n<li>Use the evidence to choose extraction boundaries, target module names, migration order, and test coverage.</li>\n</ul>\n</li>\n<li><p>This workflow defaults to a report and plan. Implement only when the user's request already authorizes execution or\nthe user subsequently approves it; do not require a separate request for an unchanged, already authorized outcome.</p>\n</li>\n</ol>\n<h2>Refactor Plan Format</h2>\n<p>For each selected file, include:</p>\n<ul>\n<li>Current role: the file's apparent responsibility and why line count is a symptom.</li>\n<li>Semantic pass: the exact symbol/reference/history inspection to run before moving code.</li>\n<li>Split proposal: 2-5 target modules or files with responsibilities.</li>\n<li>Migration order: small, reviewable steps that preserve public behavior.</li>\n<li>Verification: narrow tests, type checks, builds, or smoke checks that prove the split.</li>\n</ul>\n<p>Lead each plan with one explicit verdict: <code>### ✂ Split justified</code>, <code>### \uD83E\uDDF1 Keep intact</code>, or\n<code>### ⚠️ Generated — change the generator</code>. Use a compact evidence table for repeated criteria. When proposing a split,\nshow the source and target modules as a tree only when it clarifies ownership.</p>\n<p>If a selected file is generated or vendored because <code>--include-generated</code> was used, plan against the generator, schema,\nor upstream source instead of hand-splitting generated output.</p>\n<h2>Guard Rails</h2>\n<ul>\n<li>Treat the table as source of truth for size ranking only; rank refactor priority separately.</li>\n<li>Keep the plan cohesive; do not split solely to reduce line count.</li>\n<li>Prefer existing project module boundaries and naming conventions.</li>\n<li>Call out when the helper used its portable LOC estimate instead of <code>tokei</code>.</li>\n</ul>\n<h2>Completion</h2>\n<p>Complete with the exhaustive threshold report plus evidence-ranked plans only for candidates whose cohesion or change\nrisk justifies a split. Lead with <code>### \uD83D\uDD0E Large-file scan — &lt;candidate count&gt;</code>, state when a large file should remain\nintact and why, and surface the portable-LOC fallback as <code>⚠️ Approximate counts</code> when used. Keep the helper's exhaustive\ntable, paths, LOC values, and commands exact and undecorated.</p>\n","files":[{"path":"agents/openai.yaml","sizeBytes":43,"isText":true},{"path":"scripts/large-file-refactor.py","sizeBytes":14701,"isText":true},{"path":"SKILL.md","sizeBytes":3946,"isText":true}],"reviewScore":null,"reviewSummary":null,"trust":{"provenance":"trusted-source-unreviewed","notice":"Community-authored content, reproduced verbatim and not vetted as instructions.
