Starting a new app often requires many architecture and tooling decisions. This skill turns a plain-language request into a template-guided plan, stack choice, and agent workflow.

Mock APIs are hard to keep realistic, aligned with contracts, and useful for tests. This skill helps design stateful mocks, scenarios, fixtures, deployment steps, and documentation.

API reviews can miss authorization flaws, unsafe inputs, weak rate limits, and exposed errors. This skill organizes authorized REST and GraphQL testing into seven focused phases.

API flaws can expose data, bypass authorization, and disrupt services. This skill provides implementation patterns and review checklists for common API security controls.

Choosing an API style and consistent conventions requires many connected decisions. This skill provides focused guidance for design, security, evolution, validation, and documentation.

API testers need repeatable checks for hidden endpoints, authorization flaws, and injection issues. This skill organizes API fuzzing workflows for authorized bug bounty and penetration testing.

API assessments can miss authorization, injection, and protocol-specific weaknesses. This skill organizes scoped tests for REST, SOAP, and GraphQL interfaces.

Incomplete API documentation slows integrations and increases support demand. This skill structures specifications, examples, portals, SDK guidance, validation, and migration content for developer audiences.

API teams need consistent contracts that are easy to use and maintain. This skill guides REST and GraphQL design with templates, checklists, and review criteria.

Protected binaries can obstruct legitimate debugging, malware analysis, and security research. This skill explains common defenses, analysis methods, bypass options, and documentation practices for authorized work.

Complex AI projects often need several skills, checkpoints, and validation steps. This skill guides Claude, Codex, and Claude Code through structured Antigravity workflows.

Async Angular interfaces often show stale data, hide failures, or permit duplicate actions. This skill supplies practical patterns for clear, responsive state handling.

Angular teams can struggle to choose suitable state tools and patterns. This skill provides decision guidance and implementation examples for Signals, NgRx, and RxJS.

AngularJS modernization is complex across components, services, routing, forms, and dependency injection. This skill guides staged Angular migration with ngUpgrade patterns, examples, milestones, and validation practices.

Angular performance issues can hide in change detection, data fetching, bundles, rendering, and hydration. This skill applies prioritized modern Angular patterns during implementation, review, and refactoring.

Modern Angular projects require clear choices across Signals, routing, rendering, and change detection. This skill provides practical patterns for building and modernizing Angular applications.

Complex Compose applications require consistent patterns for state, navigation, and recomposition. This skill provides focused Kotlin guidance and production-oriented examples for modern Android interfaces.

Unclear events and inconsistent conversions make analytics difficult to trust. This skill creates decision-focused measurement plans, quality scores, validation steps, and governance guidance.

Amplitude workflows require careful tool lookup, ID resolution, and status checks. This skill guides Claude, Codex, and Claude Code through Rube MCP tool sequences for common Amplitude tasks.

Building fast, relevant Algolia search requires coordinated frontend, indexing, security, and ranking decisions. This skill provides practical patterns for each part of that workflow.
