Needs (stated): API key · Paid account

Searchable UI/UX design intelligence covering styles, palettes, font pairings, UX guidelines, icons, and stack-specific implementation for web, mobile, and desktop.

• Implementation

Use when implementing any feature or bugfix, before writing implementation code

• Requirements
• Implementation

Test-driven development reference covering what a good test is, seams, anti-patterns, and the red-green loop rules.

Grounds every implementation decision in official documentation. Use when you want to verify an approach against the official docs before implementing it, or when you want authoritative, source-cited code free from outdated patterns. Use when building with any framework or library where correctness matters.

• Implementation

Needs (stated): Python

Creates specs before coding. Use when starting a new project, feature, or significant change and no specification exists yet. Use when drafting a PRD or requirements document with objectives and scope, or when requirements are unclear, ambiguous, or only exist as a vague idea. Use when a single requirement spans several independently testable capabilities and needs decomposing into a capability map of modules before specifying.

• Requirements
• Implementation

Guides stable API and interface design. Use when designing APIs, module boundaries, or any public interface. Use when creating REST or GraphQL endpoints, defining type contracts between modules, or establishing boundaries between frontend and backend.

by addyosmani/agent-skills

• Implementation

Subjects every non-trivial decision to a fresh-context adversarial review before it stands. Use when you want every assumption cross-examined before proceeding, when stress-testing a plan for hidden failure modes, when correctness matters more than speed, when working in unfamiliar code, when stakes are high (production auth, security-sensitive logic, a high-stakes migration, irreversible operations), or any time a confident output would be cheaper to verify now than to debug later.

• Testing
• Release

Optimizes application performance across frontend, backend, queries, and databases using a measure-identify-fix-verify-guard workflow and Core Web Vitals targets.

by addyosmani/agent-skills

• Requirements
• Implementation
• Testing

Use when implementation is complete, all tests pass, and you need to decide how to integrate the work

by obra/superpowers

Use when executing implementation plans with independent tasks in the current session

by obra/superpowers

Shared vocabulary for designing deep modules: interface, implementation, depth, seam, adapter, leverage, and locality, with principles for testable boundaries.

by mattpocock/skills

Turns ideas into designs and specs through collaborative dialogue, classifying requests as spike, bounded, or architectural with an approval gate before implementation.

by obra/superpowers

• Requirements

Writes comprehensive implementation plans with file structure, bite-sized TDD tasks, and verification steps for engineers with no codebase context.

by obra/superpowers

• Requirements
• Design
• Implementation

Dispatches a code reviewer subagent with crafted context to catch issues after tasks, major features, or before merging.

by obra/superpowers

• Requirements
• Design

Loads a written implementation plan, reviews it critically, executes tasks with verification checkpoints, and completes the development branch.

by obra/superpowers

• Implementation

Guides receiving code review feedback with technical rigor: verify before implementing, ask before assuming, and push back with reasoning when warranted.

by obra/superpowers

• Implementation

Ensures work happens in an isolated workspace using native worktree tools or git worktree fallback, with detection and safety checks.

by obra/superpowers

Decomposes work into small verifiable tasks with acceptance criteria, dependency graphs, vertical slicing, and checkpoints.

by addyosmani/agent-skills

• Requirements
• Implementation

Delivers changes in thin, verifiable vertical slices, implementing, testing, verifying, and committing each increment before moving on.
