Validates technical feasibility and designs architecture

Analyze and prioritize technical debt with refactoring recommendations. Use when evaluating code quality or planning debt reduction.

查询集成连接器和API配置（v3_openapi数据库）。使用 exec_sql 工具执行查询。

Maintains detailed log of errors, bugs, and debugging sessions encountered during development. Use when encountering errors, debugging issues, or solving technical problems. Creates structured ERROR_LOG.md with error details, root causes, solutions, and prevention strategies. Complements project-logger (strategic decisions) with tactical debugging knowledge.

Implement comprehensive input validation on both client and server sides, using allowlists over blocklists, sanitizing user input, and providing specific error messages to prevent security vulnerabilities. Use this skill when writing validation logic for forms, API endpoints, function parameters, or any user input. Use this skill when implementing server-side validation to ensure data integrity and security, adding client-side validation for immediate user feedback, or sanitizing input to prevent injection attacks. Use this skill when working with form components, API route handlers, data processing functions, or validation schemas. Use this skill when defining validation rules for data types, formats, ranges, required fields, or business logic constraints across all application entry points.

Automatically applies when creating FastAPI endpoints, routers, and API structures. Enforces best practices for endpoint definitions, dependency injection, error handling, and documentation.

Apply pytest best practices and project testing conventions. Use when writing or modifying tests.

Analyze and visualize state flow in LangGraph pipelines. Use when debugging state mutations, tracing data flow between nodes, identifying orphan state keys, detecting read/write dependencies, or generating Mermaid diagrams of state transitions. Triggers on phrases like "visualize state flow", "trace state key", "which nodes touch X", "state dependencies", "debug state mutation", "orphan state keys", "state flow diagram".

Project handover process for lead generation websites. Documentation, training, credentials, maintenance. Use when project complete.

Use when starting work after context compaction, switching features, or gathering context without re-reading entire files - searches anchor tags to find relevant architecture/pattern documentation

Use when writing or improving README files. Not all READMEs are the same — provides templates and guidance matched to your audience and project type.

Documentation lifecycle management skill. Activates when user mentions documentation, docs, sync, quality, validation, releases, or setup. Routes to appropriate agent (doc-expert for orchestration, doc-writer for content) and provides gentle reminders about documentation health.

Comprehensive TAG system validator and policy enforcer that monitors, validates, and corrects TAG usage across code, tests, and documentation. Use when ensuring TAG compliance, validating TAG policy violations, analyzing TAG coverage, or when maintaining TAG system integrity and governance.

Type-safe UI component library for the East language. Use when writing East programs that define user interfaces with declarative components. Triggers for: (1) Writing East programs with @elaraai/east-ui, (2) Creating layouts with Box, Flex, Stack, Grid, (3) Forms with Input, Select, Checkbox, Switch, Slider, (4) Data display with Table, TreeView, DataList, Gantt, Planner, (5) Charts with Chart.Line, Chart.Bar, Chart.Area, Chart.Pie, Chart.Scatter, (6) Overlays with Dialog, Drawer, Popover, Menu, Tooltip, (7) State management with State.readTyped, State.writeTyped.

Looks up SEO best practices for meta tags, Open Graph, Twitter Cards, and structured data (JSON-LD), returning Google/official documentation URLs with concise summaries. Use when user asks about SEO requirements (e.g., "title tag length", "og:image size"), meta tags (e.g., "canonical", "robots"), social media tags (e.g., "Open Graph", "Twitter Card"), or structured data schemas (e.g., "Article schema", "Product JSON-LD", "FAQ markup").

RDRA operations (draft creation / consistency check / reporting) on Notion via MCP. PoC-0: only loading check.

Soracom frontend/UI guidelines covering SDS component usage, accessibility, localization, and website repo conventions (website-users / website-developers). Use when designing console flows, writing documentation UI snippets, or updating frontend repos.

Generates comprehensive README.md files for Docker Compose projects by analyzing compose.yml and .env.example files. Use when user requests documentation for a docker-compose folder or asks to create/update README files for container services.

Expert API development including REST, GraphQL, OpenAPI, versioning, and documentation

API protocol guide for Sunrei project. Use when writing API endpoints, request/response type naming, and HTTP method conventions.
