The default MATLAB patterns for AWGN (e.g., 'measured' option, manual SNR formulas) produce subtly incorrect results. This skill specifies the correct calling conventions, required function usage, and critical anti-patterns that must be avoided.","version":1,"lift":{"pass_rate_delta_pts":47.83,"pass_rate_pct":95.7,"total_cases":23,"passed_cases":22,"tokens_delta_pct":83.2,"turns_delta_pct":0,"verdict":"mixed","benchmark_model":"gemini-3.6-flash","grading_method":"judged","completed_at":"2026-08-16T18:32:28.373436+00:00"},"skill_score":null,"benchmark_models":[{"model":"gemini-3.6-flash","headline":true,"delta_pts":47.83,"with_pass_pct":95.7,"without_pass_pct":47.8,"tokens_delta_pct":83.2,"turns_delta_pct":0,"total_cases":23,"cases_aggregated":23,"verdict":"mixed","never_hurt":true,"completed_at":"2026-08-16T18:32:28.373436+00:00","run_id":"5fdbf413-68a2-44df-a7e1-9db7c40d22ce","version_number":1,"is_latest_version":true,"gate":null}],"trust":{"skill_safety":"passed","safety_status":"clean","intent_verdict":"safe","content_status":"clean","indexable":true},"license":"https://www.mathworks.com/content/dam/mathworks/license/pmrl/license.md","install_count":0,"manifest_hash":"74f6e2e182cf790d47e77c38117c44b1ba92df09d33927db962a5bc2fd0d6935","raw_url":"https://app.decimal.ai/s/matlab-matlab-add-awgn/SKILL.md","scorecard_url":"https://app.decimal.ai/skills/matlab-matlab-add-awgn"}
