- testComeOnOliver/skillshubPersistent verification mode. Use when the user explicitly says `/test` or clearly wants exhaustive test, QA, and fix loops before signoff, especially when they want you to keep grinding while they are away. Bias Codex toward running the relevant existing test stack, browser or desktop verification, and diagnosis repeatedly until the requested surface is verified or a real blocker remains.TestingNo warnings★ 64↓ —Also in 1 other repo

- test-reviewNickCrew/Claude-CortexReview test quality and audit test coverage for any module. This skill should be used when reviewing existing tests, auditing test gaps, writing new tests, or when asked to assess test health. It pipelines testing standards into the audit workflow to produce a prioritized gap report. The output is a report, not code — do not write test implementations until the report is reviewed.TestingNo warnings★ 61↓ —
- repo-cleanupNickCrew/Claude-CortexUse when a repository needs cleanup of dead code, build artifacts, unused dependencies, outdated docs, or stale tests - provides safe cleanup workflows, validation steps, and reporting templates for code, deps, docs, tests, and sprint archives.TestingNo warnings★ 61↓ —
- dev-workflowsNickCrew/Claude-CortexUse when running builds, executing tests, or improving developer experience workflows - provides structured guidance for build/test execution and DX improvement.TestingNo warnings★ 61↓ —
- dataset-curatorNickCrew/Claude-CortexUse this skill when designing, cleaning, deduplicating, or documenting datasets for model training and evaluation including schema design, class imbalance handling, and train/val/test splits. Not for running model training or hyperparameter tuning. Not for real-time data pipeline engineering.TestingNo warnings★ 61↓ —
- test-generationNickCrew/Claude-CortexUse when generating tests for new or existing code to improve coverage - provides a structured workflow for analyzing code, creating tests, and validating coverage goals.TestingNo warnings★ 61↓ —
- prompt-engineeringNickCrew/Claude-CortexOptimize prompts for LLMs and AI systems with structured techniques, evaluation patterns, and synthetic test data generation. Use when building AI features, improving agent performance, or crafting system prompts.TestingNo warnings★ 61↓ —
- constructive-dissentNickCrew/Claude-CortexStructured disagreement protocols that expose weaknesses, test assumptions, and generate alternatives. Use when stress-testing proposals, playing devil's advocate, challenging architectural decisions, or auditing assumptions before finalizing plans.TestingNo warnings★ 61↓ —
