Guides test strategy for unit, integration, and E2E testing. Use when junior asks "how do I test", "write tests", "what should I test", "test coverage", "mocking", or works with Vitest, Jest, Playwright. Provides testing pyramid and AAA patterns.
Verifies junior truly understands code they wrote through line-by-line walkthrough. BLOCKING gate that must pass to complete any task. Triggered during /own:done flow.
Designs structured benchmarks for comparing algorithms, models, or implementations. Selects appropriate metrics (latency, throughput, memory, accuracy), designs representative test cases, captures hardware/software context, produces comparison tables with tradeoff analysis, and includes reproduction instructions. Triggers on: "benchmark", "compare performance", "which is faster", "latency comparison", "memory comparison", "run benchmark", "design benchmark", "compare implementations", "evaluate algorithms", "performance comparison", "throughput test", "speed test". Use this skill when comparing two or more implementations, algorithms, or models.
Challenges AI-generated plans, code, designs, and decisions before you commit. Pairs with any other skill as a review layer. Uses pre-mortem analysis, inversion thinking, and Socratic questioning to find what AI missed — blind spots, hidden assumptions, failure modes, and optimistic shortcuts. The skill that asks "are you sure about that?" so you don't have to. Triggers on: "challenge this", "devils advocate", "stress test this plan", "what could go wrong", "poke holes in this", "review this critically", "second opinion on this design", "what am I missing". Use this skill when you need critical review of any AI-generated output, architecture decision, implementation plan, or code before committing to it.
Gemini CLI specialized for multimodal file processing only. MUST use when PDF, video, audio, or image files need content extraction. Auto-triggers: file extensions .pdf, .mp4, .mov, .mp3, .wav, .m4a. For research/codebase analysis → use general-purpose subagent (Opus) instead. Planning/design → use Codex instead.
Linting and code quality workflows for MailPoet development (PHP, JS/TS, CSS/SCSS). Use when fixing code style or following the development workflow.
Reviews codebases, architectures, PRs, and technical plans for vanity engineering — code and systems built for the developer's ego, resume, or intellectual pleasure rather than delivering user or business value. Triggers on: "review this code", "is this over-engineered", "code review", "architecture review", "complexity audit", "vanity check", "is this necessary", "simplify this", "tech debt review", or any request to evaluate whether code or architecture is justified by actual requirements. Also trigger when the user shares a codebase and asks for feedback, when discussing framework/library choices, when reviewing PRs, or when someone is debating whether to refactor or rebuild. Nudge activation when you detect patterns of unnecessary abstraction, premature optimization, or resume-driven technology choices in code the user shares — even if they haven't asked for a vanity review.
Activates when users start a new novel project - guides them through the seven-step methodology (constitution → specify → clarify → plan → tasks → write → analyze) with gentle prompts and explanations
Social engineering testing - phishing, pretexting, vishing, and physical security assessment techniques.
Generate publication-quality academic diagrams and plots from paper methodology text using optimize_input, plan_diagram, generate_image, and critique_image tools.
Knowledge and utilities for creating animated GIFs optimized for Slack. Provides constraints, validation tools, and animation concepts. Use when users request animated GIFs for Slack like "make me a GIF of X doing Y for Slack."
Review and improve a tutorial for clarity, correctness, and learner comprehension
Format a directory to follow the "Learn X in 60 Minutes" tutorial conventions described in website/docs/blog/posts/all.learn_X_in_60_minutes.how_to_guide.md
Schema reference for comment enrichment. The enrichment workflow is printed by `wednesday-skills map` in the `[ENRICH]` block — follow those instructions.
Master TypeScript's advanced type system including generics, conditional types, mapped types, template literals, and utility types for building type-safe applications. Use when implementing complex type logic, creating reusable type utilities, or ensuring compile-time type safety in TypeScript projects.
This skill should be used when the user asks to "create a filter", "write a tokf filter", "add a filter for <tool>", "how do I filter output", or needs guidance on tokf filter step types, templates, pipes, or placement conventions.
Use to plan trainings, office hours, and adoption programs for new creative or brand initiatives.
Toolkit to map EdTech programs to academic standards, accreditation, and employer competency frameworks.
Use when reviewing content for clarity, generating questions, or checking alignment. Triggers on "review for clarity", "suggest questions", "check alignment", "comprehensive review".
AI-assisted UI generation patterns for json-render, v0, Bolt, and Cursor workflows. Covers prompt engineering for component generation, review checklists for AI-generated code, design token injection, refactoring for design system conformance, and CI gates for quality assurance. Use when generating UI components with AI tools, rendering multi-surface MCP visual output, reviewing AI-generated code, or integrating AI output into design systems.
Creates polished demo videos for skills, tutorials, and CLI demonstrations. Use when producing video showcases, marketing content, or terminal recordings.
Design token management with W3C Design Token Community Group specification, three-tier token hierarchy (global/alias/component), OKLCH color spaces, Style Dictionary transformation, and dark mode theming. Use when creating design token files, implementing theme systems, managing token versioning, or building design-to-code pipelines.
