Grounded in practical engineering patterns for production ML systems.</p>\n<h2>Why Install This Skill</h2>\n<p>Your agent makes informed decisions about fine-tuning approaches, quantization trade-offs, GPU selection, and serving architecture with real VRAM budgets and benchmarks. Fillable templates turn training runs, eval comparisons, and quantization decisions into reviewable records, and the bundled eval-overlap checker catches train/eval contamination before it invalidates a benchmark.</p>\n<h2>What You Get</h2>\n<table>\n<thead>\n<tr>\n<th>Directory</th>\n<th>Purpose</th>\n</tr>\n</thead>\n<tbody>\n<tr>\n<td><code>SKILL.md</code></td>\n<td>Core methodology, trigger conditions, reference index</td>\n</tr>\n<tr>\n<td><code>references/</code></td>\n<td>Deep-dive reference files loaded on demand</td>\n</tr>\n<tr>\n<td><code>templates/</code></td>\n<td>Fillable records: training-run record, eval regression table, quantization decision record</td>\n</tr>\n<tr>\n<td><code>scripts/</code></td>\n<td><code>check-eval-overlap.py</code> — detects test-set leakage between train and eval corpora</td>\n</tr>\n<tr>\n<td><code>evals/</code></td>\n<td>Output-quality eval manifest for the skill's methodology cases</td>\n</tr>\n</tbody>\n</table>\n<h2>Triggers</h2>\n<p>Setting up fine-tuning runs, quantizing models, selecting training infrastructure, deploying inference servers, evaluating model quality, or triaging a model regression.</p>\n<h2>Requirements</h2>\n<p>Assumes familiarity with PyTorch/HuggingFace ecosystem. References cover vLLM, llama.cpp, TGI, DeepSpeed, and accelerate. The bundled script needs only Python 3 (standard library).</p>\n<h2>Quick Start</h2>\n<p>Check an eval corpus for leakage against your training data before trusting any eval score:</p>\n<pre><code>python3 ml-engineering/scripts/check-eval-overlap.py --train data/train/ --eval data/eval/\n</code></pre>\n<p>Each eval file is reported with its overlap fraction against the training corpus; an eval file that shares more than 10% of its text with training is flagged <code>LEAK</code> and the script exits 1, so it can gate a CI pipeline. Add <code>--json</code> for machine-readable output, <code>--token-ngram 5</code> to compare token sequences instead of character shingles, and <code>--max-overlap-fraction 0.05</code> to tighten the threshold.</p>\n<p>Load SKILL.md for the methodology overview and reference table, then load specific references or templates as needed for the task at hand.</p>\n","files":[{"path":"evals/evals.json","sizeBytes":15406,"isText":true},{"path":"README.md","sizeBytes":2458,"isText":true},{"path":"references/evaluation-and-lineage.md","sizeBytes":3823,"isText":true},{"path":"references/evaluation.md","sizeBytes":1318,"isText":true},{"path":"references/fine-tuning.md","sizeBytes":1342,"isText":true},{"path":"references/quantization-inference.md","sizeBytes":42379,"isText":true},{"path":"references/training-infrastructure.md","sizeBytes":3969,"isText":true},{"path":"scripts/check-eval-overlap.py","sizeBytes":9498,"isText":true},{"path":"scripts/test_check_eval_overlap.py","sizeBytes":7891,"isText":true},{"path":"SKILL.md","sizeBytes":5916,"isText":true},{"path":"templates/drift-response-record.md","sizeBytes":713,"isText":true},{"path":"templates/eval-regression-table.md","sizeBytes":1765,"isText":true},{"path":"templates/model-lineage-record.md","sizeBytes":918,"isText":true},{"path":"templates/quantization-decision-record.md","sizeBytes":2496,"isText":true},{"path":"templates/training-run-record.md","sizeBytes":2841,"isText":true}],"reviewScore":null,"reviewSummary":null,"trust":{"provenance":"trusted-source-unreviewed","notice":"Community-authored content, reproduced verbatim and not vetted as instructions.
