agent-skills-standard

common-tdd

Implements a strict Red-Green-Refactor loop to ensure zero production code is written without a prior failing test. Use when: creating new features, fixing bugs, or expanding test coverage.

Skill Creator

Standards for creating new High-Density Agent Skills with optimal token economy.

angular-ssr

Implement Angular SSR with hydration, TransferState caching, and per-route render modes. Use when configuring Angular Universal SSR, client hydration, static prerendering, or preventing double-fetching.

android-architecture

Apply Clean Architecture layering, modularization, and Unidirectional Data Flow in Android projects. Use when setting up project structure, placing code in layers, configuring feature/core modules, or implementing UDF patterns.

common-best-practices

Enforce SOLID principles, guard-clause style, function size limits, and intention-revealing naming across all languages. Use when refactoring for readability, applying clean-code patterns, reviewing naming conventions, or reducing function complexity.

common-workflow-writing

Rules for writing concise, token-efficient workflow and skill files. Prevents over-building that requires costly optimization passes. Use when creating or editing workflow files, SKILL.md files, or new skill definitions.

common-protocol-enforcement

Enforce Red-Team verification and adversarial protocol audit. Use when verifying tasks, performing self-scans, or checking for protocol violations. Load as composite for all sessions.

android-resources

Organize strings, drawables, and localization resources in Android projects. Use when managing Android resources, plurals, or adding multi-language support.

common-documentation

Write effective code comments, READMEs, and technical documentation following intent-first principles. Use when adding comments, writing docstrings, creating READMEs, or updating any documentation.

common-product-requirements

Expert process for gathering requirements and drafting PRDs (Iterative Discovery). Use when creating a PRD, speccing a new feature, or clarifying requirements.

common-feedback-reporter

Pre-write skill violation audit. Checks planned code against loaded skill anti-patterns before any file write. Use when writing Flutter/Dart code, editing SKILL.md files, or generating any code where project skills are active. Load as composite alongside other skills. When a violation is detected and Auto-fixed: YES, also load +common/common-learning-log to record the mistake.

typescript-tooling

Development tools, linting, and build config for TypeScript. Use when configuring ESLint, Prettier, Jest, Vitest, tsconfig, or any TS build tooling.

JavaScript Tooling

Development tools, linting, and testing for JavaScript projects.

common-system-design

Enforce separation of concerns, dependency inversion, and resilience patterns across layered and distributed architectures. Use when designing new features, evaluating module boundaries, selecting architectural patterns, or resolving scalability bottlenecks.

angular-routing

Configure Angular Router with lazy-loaded routes, functional guards, and component input binding. Use when defining routes, lazy-loading features, creating route guards, or setting up resolvers.

android-navigation-type-safe

Implement type-safe Jetpack Navigation Compose routes using Kotlin serialization. Use when defining navigation graphs with type-safe destinations in Jetpack Compose.

angular-security

Harden Angular apps against XSS, CSP violations, and unauthorized access. Use when implementing XSS protection, Content Security Policy, or auth guards in Angular.

typescript-language

Apply modern TypeScript standards for type safety and maintainability. Use when working with types, interfaces, generics, enums, unions, or tsconfig settings.

angular-state-management

Implement application state with Angular Signals, computed derivations, and NgRx Signal Store. Use when implementing reactive state with signal(), computed(), effect(), or @ngrx/signals in Angular.

android-concurrency

Write correct coroutine scopes, Flow collection, and dispatcher injection in Android. Use when writing suspend functions, choosing between StateFlow and SharedFlow, or injecting Dispatchers for testability.

common-context-optimization

Maximize context window efficiency, reduce latency, and prevent lost-in-middle issues through strategic masking and compaction. Use when token budgets are tight, tool outputs flood the context, conversations drift from intent, or latency spikes from cache misses.

android-navigation

Implement navigation with Jetpack Compose Navigation and App Links on Android. Use when implementing navigation flows, deep links, or backstack handling.

typescript-best-practices

Write idiomatic TypeScript patterns for clean, maintainable code. Use when writing or refactoring TypeScript classes, functions, modules, or async logic.

common-llm-security

OWASP LLM Top 10 (2025) audit checklist for AI applications, agent tools, RAG pipelines, and prompt construction. Use when performing any security review touching LLM client code, prompt templates, agent tools, or vector stores.

android-state

Configure ViewModel state emission with StateFlow, sealed UiState classes, and lifecycle-safe collection in Android. Use when working with ViewModels, UiState patterns, or exposing state to Compose UI.
