Using "nestjs-oop-design-patterns". A checkout service validates orders, calls a payment SDK, and maps database rows.
Expected outcome:
Using "nestjs-oop-design-patterns". Should a service with one stable pricing rule use Strategy?
Expected outcome:
Using "nestjs-oop-design-patterns". Does an in-process event guarantee publication after a database commit?
Expected outcome:
All 25 static findings are false positives involving ordinary design guidance, Markdown identifiers, or headings. Backticks mark inline code, and the reconnaissance matches contain no system enumeration instructions. No evidence found of prompt injection, credential theft, unauthorized execution, or data exfiltration in the reviewed passages and surrounding files.

Identify unrelated responsibilities and propose a small refactor that preserves behavior and public contracts.
Compare direct integration, Adapter, and Strategy using vendor coupling, variation, and substitution requirements.
Define tests for invariants, adapter substitution, Nest provider wiring, and transport behavior before refactoring.
Review [class] and its callers. Explain its role, responsibilities, and one concrete design concern without editing files.
Compare a direct solution, Strategy, and Factory for [observed variation]. Recommend one using repository evidence and explain its testing cost.
Refactor [service] to separate [misplaced responsibility]. Preserve public behavior and user changes, add focused tests, and verify Nest provider wiring.
Review [workflow] for adapter substitution, transaction boundaries, and event delivery guarantees. Compare direct coordination with outbox or saga designs and specify contract tests.

Audit NestJS Code with Evidence-Backed Findings
NestJS repositories can hide boundary flaws and runtime risks that lint results alone cannot reveal. This skill combines local evidence collection and semantic review into one prioritized report.
Prepare NestJS Commits and Pull Requests
Mixed changes and unclear publication requests can produce misleading commits or unintended remote updates. This skill guides verified Git changes and accurate messages within authorized scope.
Design and Review NestJS Architecture
Unclear module boundaries make NestJS changes harder to test and coordinate. This skill guides evidence-based architecture decisions, explicit ownership, and incremental boundary repairs.
Build and Verify Maintainable NestJS Software
NestJS changes can introduce incompatible syntax, hidden side effects, and public API regressions. This skill guides repository inspection, focused implementation, and evidence-based verification.
Improve NestJS Features, Performance, and Reliability
NestJS runtime changes can create latency, security, and deployment failures when teams lack clear contracts and measurements. This skill guides component selection, bottleneck diagnosis, and reliable implementation using repository evidence and focused tests.
Audit NestJS Features Against Their Roadmaps
Source code alone cannot establish whether a NestJS feature satisfies its roadmap. This skill compares requirements with revision-specific evidence and reports completed work, gaps, legacy paths, bugs, and blockers.
Analyze Patterns Across Your Codebase
by C0ntr0lledCha0s
Large codebases hide repeated structures and inconsistent decisions. This skill maps design patterns, architecture, conventions, duplication, and anti-patterns with evidence and recommendations.
Build Reliable Playwright Tests
by C0ntr0lledCha0s
Playwright test suites can become flaky, slow, and difficult to maintain. This skill provides practical patterns for locators, fixtures, page objects, debugging, mocking, and configuration.
Build Starknet Apps with starknet.js
by internet-court
Starknet integrations require precise provider, account, transaction, and fee handling across several APIs. This skill provides focused starknet.js v9.x patterns for reliable TypeScript applications.
Improve Vue 3 Code Quality
by vuejs-ai
Vue projects often collect reactivity, component, and performance mistakes over time. This skill gives targeted Vue 3 guidance for safer patterns and clearer code.
Build Type-Safe React Components
by softaworks
React TypeScript work often needs precise event, hook, and route types. This skill provides focused patterns for typed components, React 19 APIs, and routing.
Improve Vue Options API Code
by vuejs-ai
Vue Options API projects often lose type safety and correct this binding. This skill gives focused rules for safer Vue 3 components.
