Use when you need to add or review Flyway database migrations in a Spring Boot application — Maven dependencies, db/migration scripts, spring.flyway.* configuration, baseline and validation, and alignment with JDBC or Spring Data JDBC. Part of the skills-for-java project
Refine an existing design tree until key branches become implementation-ready. Use when the high-level structure already exists but important branches remain vague, shallow, or unresolved. Trigger when the user needs deeper decomposition, edge-case coverage, failure-path clarification, interface detail, or validation criteria for a partially designed system. Do not use to create the initial design skeleton from scratch or to compare options for a single explicit decision node.
Design and operate data quality programs for financial data — golden source architecture, validation rules, data lineage, exception management, profiling, and governance. Use when building validation rules for pricing or client data pipelines, designing a data quality monitoring framework, establishing golden source designations across systems, implementing data lineage for BCBS 239 or MiFID II, investigating reconciliation breaks or billing errors traced to bad data, preparing for regulatory exams on data accuracy, building data quality scorecards, or defining data stewardship roles. Trigger on: data quality, golden source, data lineage, data validation, data profiling, exception management, data governance, BCBS 239, data completeness, data accuracy, validation rules, data anomaly, data stewardship, data quality scorecard.
Tests WebSocket API implementations for security vulnerabilities including missing authentication on WebSocket upgrade, Cross-Site WebSocket Hijacking (CSWSH), injection attacks through WebSocket messages, insufficient input validation, denial-of-service via message flooding, and information leakage through WebSocket frames. The tester intercepts WebSocket handshakes and messages using Burp Suite, crafts malicious payloads, and tests for authorization bypass on WebSocket channels. Activates for requests involving WebSocket security testing, WS penetration testing, CSWSH attack, or real-time API security assessment.
Expert-level development skill for building, debugging, reviewing, and migrating Freshworks Platform 3.0 marketplace applications. REQUIRES Node.js 24.x + FDK 10.x installed BEFORE use—checks prerequisites and refuses to proceed without them. Does NOT install or manage FDK/Node—use fw-setup skill. Before fdk validate, follow this SKILL.md Manifest + toolchain gate (fw-setup if CLI wrong, /fdk-migrate on 2.x or legacy engines, then validate—never downgrade to FDK 9/Node 18 as a shortcut except LAST RESORT after six validate iterations). New apps default to FDK 10.0.1 and Node.js 24.x; FDK 9.x/Node 18.x allowed when explicitly requested with deprecation notice. Use for: (1) Creating Platform 3.0 apps (frontend, serverless, hybrid, OAuth), (2) Debugging validation errors, (3) Migrating Platform 2.x apps to 3.0, (4) Reviewing manifest.json, requests.json, oauth_config.json, (5) Implementing Crayons UI, (6) Integrating external APIs or OAuth providers, (7) Any Freshworks Platform 3.0 app development, FDK CLI, or marketplace submission task.
Interacts with Google Cloud services using the gcloud CLI safely and efficiently. Covers command validation, data reduction, safety guardrails with a denylist, and workflows for discovery and investigation. You MUST read this skill before invoking any gcloud command. Use when managing cloud resources, querying configurations, or troubleshooting issues via gcloud. Don't use when writing or debugging Google Cloud client library code or raw REST/gRPC API interactions.
Use when defining field mappings for data streams, populating ecs.yml with ECS field references, selecting ECS categorization values, choosing custom field types, or troubleshooting mapping validation failures.
AI SDLC change-impact and lifecycle recovery workflow. Use when a requirement, acceptance criterion, decision, API contract, risk assumption, or other traced source changed after downstream artifacts were created and an AI assistant must identify stale artifacts, affected lifecycle stages, and evidence-backed reopen or revalidation actions without silently rewriting authoritative state. Supports `--quick-flow` for focused trace scanning and `--full-flow` for strict state and source-evidence gates.
Use when working on Nuxt 4+ projects - provides server routes, file-based routing, middleware patterns, Nuxt-specific composables, and configuration with latest docs. Covers h3 v1 helpers (validation, WebSocket, SSE) and nitropack v2 patterns. Updated for Nuxt 4.3+.
Create PydanticAI agents with type-safe dependencies, structured outputs, and proper configuration. Use when building AI agents, creating chat systems, or integrating LLMs with Pydantic validation.
Next.js 15 App Router patterns. Trigger: When working in Next.js App Router (app/), Server Components vs Client Components, Server Actions, Route Handlers, caching/revalidation, and streaming/Suspense.
Dependency injection workflow for Spring Boot projects covering constructor-first patterns, optional collaborator handling, bean selection, and validation practices.
