Use when the user wants to compete, climb, medal, win, diagnose a plateau, or improve a measured result in any Kaggle competition: tabular, computer vision, NLP, audio, simulation or agent ladders, code competitions, and judge-scored hackathons. Also use for competition strategy, live reconnaissance, validation, OOF predictions, ensembling, stacking, pseudo-labeling, feature engineering, experiment portfolios, GPU or submission-budget allocation, BEST_KNOWN protection, kernel batches, leaderboard analysis, or unattended Kaggle grinding. This is the universal strategy and execution skill; pair it with the separate `kaggle` infrastructure skill for authentication, downloads, kernels, and API plumbing. Do not use it for authentication, credential repair, dataset downloads, badges, account setup, or CLI/API installation alone.
