Design Reliable Tests for Codebases
Many teams add tests without a clear plan, which creates gaps and slow suites. This skill guides test type selection, templates, coverage targets, and validation steps.
This skill is part of a pack
Install the whole pack to get every skill the task needs, in one command.
Copy this request to your Agent. It includes the canonical Skill page and manifest.
Review the Skillstore skill "designing-tests" from https://skillstore.io/skills/cloudai-x-designing-tests.md and its manifest at https://skillstore.io/api/skills/cloudai-x-designing-tests/manifest. Verify the artifact. You may proceed after verification, subject to the environment's own policy.Your Agent should still show its plan and request any confirmation required by the security policy.
Use these links when an AI agent, crawler, or script needs clean context instead of reading the full page.
Using "designing-tests". I need tests for a user registration API.
Expected outcome:
Using "designing-tests". Our tests pass locally but coverage is low.
Expected outcome:
Using "designing-tests". We need a testing standard for a TypeScript service.
Expected outcome:
Most static findings are false positives caused by Markdown code fences, mock HTTP examples, and ordinary test templates. The skill does instruct agents to run npm test commands, which can execute project-defined scripts and should require user approval in untrusted repositories. No prompt injection or data exfiltration intent was found.
These are real local capabilities that may be expected for this skill, so they require review but are not counted as confirmed malicious behavior.

Analyze Any Codebase Fast
Understanding an unfamiliar codebase takes hours of manual exploration across scattered files and configs. This skill gives Claude a structured six-step workflow to map a project's tech stack, structure, patterns, and development commands into a clear summary report.
Design Clean REST and GraphQL APIs
Designing consistent APIs from scratch is slow and error-prone, and inconsistent endpoints confuse consumers. This skill gives Claude a structured workflow with proven patterns for endpoints, errors, versioning, authentication, and OpenAPI documentation.
Optimize Application Performance
Slow applications can hide bottlenecks across frontend, backend, database, and algorithm layers. This skill guides profiling, targeted fixes, and before-after measurement.
Design a practical software architecture
Architecture decisions can become unclear when requirements, team skills, and future growth compete. This skill compares suitable patterns and helps document a clear, reasoned decision.
Coordinate Parallel AI Subagents
Complex projects often contain independent tasks that waste time when handled sequentially. This skill shows how to plan, launch, collect, and synthesize parallel subagent work.
Animate Three.js Scenes
Three.js animation setup can be hard to structure across mixers, clips, bones, and morph targets. This skill gives focused patterns for keyframes, GLTF animations, blending, and procedural motion.
Build Better Go Tests
by 89jobrien
Go teams need consistent tests across units, integrations, mocks, benchmarks, and coverage. This skill provides practical Go testing patterns that Claude, Codex, and Claude Code can apply during development.
Improve Rust Test Coverage
by EmilLindfors
Missing tests leave Rust error paths and edge cases unprotected. This skill reviews code and tests, then suggests targeted coverage improvements.
Plan Reliable Tests Across Your Codebase
by 0xDarkMatter
This skill helps teams choose test strategies, mocks, data fixtures, coverage gates, and CI patterns without mixing test scopes. It gives Claude, Codex, and Claude Code structured guidance for unit, integration, end-to-end, TDD, and pipeline testing.
Build Python Tests with pytest TDD
by 89jobrien
Python teams often need consistent tests, coverage, and reports without losing TDD discipline. This skill provides pytest-focused workflows, examples, and reporting guidance for Claude, Codex, and Claude Code.
Improve QA Coverage With Test Automation
by davila7
Teams often miss coverage gaps and repeat manual QA planning work. This skill provides testing guidance, scaffold scripts, and coverage reporting patterns for Claude, Codex, and Claude Code.
Build Reliable Test Automation
by 89jobrien
Weak tests slow releases and hide regressions. This skill guides test strategy, TDD, automation, coverage review, and Playwright web checks.
