Testing
Unit tests, integration tests, test automation
finishing-a-development-branch
by guanyang
Use when implementation is complete, all tests pass, and you need to decide how to integrate the work - guides completion of development work by presenting structured options for merge, PR, or cleanup
evaluation
by guanyang
This skill should be used when the user asks to "evaluate agent performance", "build test framework", "measure agent quality", "create evaluation rubrics", or mentions LLM-as-judge, multi-dimensional evaluation, agent testing, or quality gates for agent pipelines.
web-renderer-test
by remotion-dev
Add a test case to the web renderer
unit-test-generator
by JackyST0
Automatically generate unit tests based on source code, supporting multiple languages and testing frameworks.
lesson-quiz
by luongnv89
Interactive lesson-level quiz for Claude Code tutorials. Tests understanding of a specific lesson (01-10) with 8-10 questions mixing conceptual and practical knowledge. Use before a lesson to pre-test, during to check progress, or after to verify mastery. Use when asked to "quiz me on hooks", "test my knowledge of lesson 3", "lesson quiz", "practice quiz for MCP", or "do I understand skills".
email-subject-lines
by OpenClaudia
Generate, evaluate, and A/B test email subject lines for maximum open rates. Includes formulas for curiosity, urgency, personalization, and more. Trigger phrases: "email subject line", "subject line ideas", "email subject", "write subject lines", "A/B test subject lines", "improve open rates", "email open rate", "subject line formulas".

golang-concurrency-patterns
by bobmatnyc
"Go concurrency patterns for production services: context cancellation, errgroup, worker pools, bounded parallelism, fan-in/fan-out, and common race/deadlock pitfalls"
spec-to-code-compliance
by trailofbits
Verifies code implements exactly what documentation specifies for blockchain audits. Use when comparing code against whitepapers, finding gaps between specs and implementation, or performing compliance checks for protocol implementations.
customaize-agent:create-skill
by NeoLabHQ
Guide for creating effective skills. This command should be used when users want to create a new skill (or update an existing skill) that extends Claude's capabilities with specialized knowledge, workflows, or tool integrations. Use when creating new skills, editing existing skills, or verifying skills work before deployment - applies TDD to process documentation by testing with subagents before writing, iterating until bulletproof against rationalization
blueprint-derive-tests
by laurigates
"Derive test regression plans from git history by identifying fix and feature commits lacking corresponding tests. Use when you need to find untested bug fixes, coverage gaps, or generate a test backlog from commit analysis."
create-evlog-enricher
by HugoRCD
Create a new built-in evlog enricher to add derived context to wide events. Use when adding a new enricher (e.g., for deployment metadata, tenant context, feature flags, etc.) to the evlog package. Covers source code, tests, and all documentation.
customaize-agent:test-skill
by NeoLabHQ
Use when creating or editing skills, before deployment, to verify they work under pressure and resist rationalization - applies RED-GREEN-REFACTOR cycle to process documentation by running baseline without skill, writing to address failures, iterating to close loopholes
Arena
by simota
codex exec / gemini CLI を直接操り、競争開発（COMPETE）と協力開発（COLLABORATE）の二大パラダイムで実装を行うスペシャリスト。COMPETE は複数アプローチを比較し最善案を採用。COLLABORATE は外部エンジンに異なるタスクを分担させ統合。Solo/Team/Quick の実行モードをサポート。
n8n-conventions
by n8n-io
Quick reference for n8n patterns. Full docs /AGENTS.md
ai-product
by sickn33
"Every product will be AI-powered. The question is whether you'll build it right or ship a demo that falls apart in production. This skill covers LLM integration patterns, RAG architecture, prompt engineering that scales, AI UX that users trust, and cost optimization that doesn't bankrupt you. Use when: keywords, file_patterns, code_patterns."
ab-test-setup
by sickn33
Structured guide for setting up A/B tests with mandatory gates for hypothesis, metrics, and execution readiness.
business-strategy

Business strategy expertise for strategic planning, competitive analysis, market entry, M&A strategy, portfolio management, and strategic decision-making. Use when analyzing competitive positioning, planning growth strategies, or making strategic decisions.
customaize-agent:test-prompt
by NeoLabHQ
Use when creating or editing any prompt (commands, hooks, skills, subagent instructions) to verify it produces desired behavior - applies RED-GREEN-REFACTOR cycle to prompt engineering using subagents for isolated testing
customaize-agent:agent-evaluation
by NeoLabHQ
Evaluate and improve Claude Code commands, skills, and agents. Use when testing prompt effectiveness, validating context engineering choices, or measuring improvement quality.
code-review:review-local-changes
by NeoLabHQ
Comprehensive review of local uncommitted changes using specialized agents with code improvement suggestions
