Testing

deepchem

by jimmc414

"Molecular machine learning toolkit. Property prediction (ADMET, toxicity), GNNs (GCN, MPNN), MoleculeNet benchmarks, pretrained models, featurization, for drug discovery ML."

geniml

by jimmc414

This skill should be used when working with genomic interval data (BED files) for machine learning tasks. Use for training region embeddings (Region2Vec, BEDspace), single-cell ATAC-seq analysis (scEmbed), building consensus peaks (universes), or any ML-based analysis of genomic regions. Applies to BED file collections, scATAC-seq data, chromatin accessibility datasets, and region-based genomic feature learning.

speckit-implement

by dceoy

Execute the implementation plan by processing and executing all tasks defined in tasks.md

speckit-specify

by dceoy

Create or update a feature specification from a natural language feature description.

speckit-clarify

by dceoy

Identify underspecified areas in the current feature spec by asking up to 5 highly targeted clarification questions and encoding answers back into the spec.

speckit-baseline

by dceoy

Generate feature specifications by analyzing existing source code.

speckit-analyze

by dceoy

Perform a non-destructive cross-artifact consistency and quality analysis across spec.md, plan.md, and tasks.md after task generation.

speckit-tasks

by dceoy

Generate an actionable, dependency-ordered tasks.md for the feature based on available design artifacts.

speckit-checklist

by dceoy

Generate a custom checklist for the current feature based on user requirements.

approval-tests

by lexler

Writes approval tests (snapshot/golden master testing) for Python, JavaScript/TypeScript, or Java. Use when verifying complex output, characterization testing legacy code, testing combinations, or working with .approved/.received files.

playwright-best-practices

by NeverSight

Provides Playwright test patterns for resilient locators, Page Object Models, fixtures, web-first assertions, and network mocking. Must use when writing or modifying Playwright tests (.spec.ts, .test.ts files with @playwright/test imports).

refactoring

by lexler

Refactoring process. Invoke immediately when user or document mentions refactoring, or proactively when code gets too complex or messy.

tdd

by lexler

Test-driven development (TDD) process used when writing code. Use whenever you are adding any new code, unless the user explicitly asks to skip TDD or the code is exploratory/spike.

collaborative-design

by lexler

Designs software features collaboratively through visual scenarios and iterative refinement. Use when designing features, tools, UIs, workflows, or any system before implementation.

atdd-team

by swingerman

This skill should be used when the user asks to "build a feature with a team", "use ATDD with agents", "create an ATDD team", "set up a team for ATDD", "orchestrate agents for ATDD", "use team-based development", "coordinate agents for feature development", "run the ATDD workflow with teammates", "add ATDD to my team", "extend my team with ATDD", "join the team with ATDD agents", "add spec-writer and reviewer to the team", or "add ATDD roles to the existing team". It orchestrates a three-agent team (spec-writer, implementer, reviewer) through a five-phase ATDD workflow: spec writing, spec review, pipeline generation, implementation, and post-implementation review. Supports extending an existing team with ATDD roles without replacing current teammates.

form-cro

by freekmurze

When the user wants to optimize any form that is NOT signup/registration — including lead capture forms, contact forms, demo request forms, application forms, survey forms, or checkout forms. Also use when the user mentions "form optimization," "lead form conversions," "form friction," "form fields," "form completion rate," or "contact form." For signup/registration forms, see signup-flow-cro. For popups containing forms, see popup-cro.

terraform

by iliaal

Terraform and OpenTofu configuration, modules, testing, state management, and HCL review. Use for "terraform module", "terraform test", "infrastructure as code", "IaC", "HCL", "tfvars", "terraform plan", "terraform apply", "OpenTofu", "tftest", or multi-environment patterns.

testing-react

by iliaal

Writes and reviews React/TypeScript tests using Vitest and React Testing Library. Use when "write react tests", "review tests", "check tests", "vitest", "component test", "hook test", "RTL", "testing library", "snapshot test", or testing/reviewing React components, hooks, and utilities.

project-execution

by athola

"Execute implementation plans with checkpoint validation, progress tracking, and quality gates. Use for task implementation, plan execution, progress tracking. Skip if no plan exists."

tdd

by jellydn

Guides through the complete TDD workflow with Red-Green-Refactor cycle
