- gsd-validate-phasecoco-research/cocoUse when validation or test coverage is missing on a phase that already shipped. Audits or reconstructs VALIDATION.md, fills the gaps and generates the missing test files.TestingNo warnings★ 961↓ —
- gsd-verify-workcoco-research/cocoUse after a phase executes, when the user wants to test the built features themselves. Runs one conversational UAT test at a time into {phase}-UAT.md and, when something fails, diagnoses it and queues fix plans for /gsd-execute-phase.TestingNo warnings★ 961↓ —
- gsd-audit-fixcoco-research/cocoUse after /gsd-audit-uat when the user wants the findings fixed, not just listed. Classifies each issue as auto-fixable or manual and fixes the auto-fixable ones with test verification and atomic commits; --severity sets the floor.TestingNo warnings★ 961↓ —
- matlab-prepare-signal-datamatlab/matlab-agentic-toolkitUse this skill when conditioning, loading, preparing, or labeling signal data for analysis or ML training. Covers: cleaning a single signal (fill gaps, remove drift, deoutlier, denoise, resample/align a time base) BEFORE analysis; building a `signalDatastore` pipeline; creating a `labeledSignalSet` for Signal Labeler; deriving labels (filename, folder, in-file, ROI, time-frequency ROI); stratified train/val/test splits; framing long signals; parallel processing; and shaping datastore output for `trainnet`. Triggers include "clean up this signal", "remove drift / detrend", "fill gaps", "remove spikes / outliers", "denoise", "resample to a uniform rate", "align channels", "labels from filenames", "stratified split", "prepare for Signal Labeler", and function names like `fillgaps`, `fillmissing`, `detrend`, `filloutliers`, `smoothdata`, `resample`, `synchronize`, `signalDatastore`, `labeledSignalSet`, `filenames2labels`, `folders2labels`, `splitlabels`, `framesig`, `framelbl`, `createDatastores`.TestingNo warnings★ 1.2K↓ —
- matlab-classify-tabular-datamatlab/matlab-agentic-toolkitUse this skill to classify tabular data end-to-end in MATLAB — load a dataset, prepare and clean it, select promising classifiers, train them, and compare accuracies with cross-validation, holdout, or hyperparameter optimization plus statistical tests. TRIGGER when: user asks to classify tabular data, pick classifiers for a dataset, compare classifier accuracy, run cross-validation or a holdout evaluation, or find the best model with statistical uncertainty. DO NOT TRIGGER when: user has non-tabular inputs (images, sequences, time series), wants a regression model, is training a specific neural network architecture (use matlab-train-network), or wants cost-sensitive learning or an arbitrary class-prior vector (this skill only supports the built-in uniform-prior toggle for imbalanced data).TestingNo warnings★ 1.2K↓ —
