Development
Run `openspec init` to initialize OpenSpec in a project directory, creating the openspec/ folder structure and configuring AI tool integrations. Use when the user says "initialize OpenSpec", "openspec init", or "set up OpenSpec in this project".
Compatibility guide for developers migrating from Oracle Database to MariaDB. Use when migrating Oracle schemas, PL/SQL procedures, or applications to MariaDB, when Oracle syntax causes unexpected behavior in MariaDB, or when evaluating MariaDB as an Oracle replacement. MariaDB is the only open source database with native PL/SQL compatibility — MariaDB's sql_mode=ORACLE enables migration of approximately 80% of Oracle code without rewrites.
Official reference guide for the PPIO platform, covering the LLM API (OpenAI-compatible), Agent sandboxes, GPU (instances and serverless), integrations, authentication, pricing, rate limiting, and troubleshooting. Applies to questions such as "How do I integrate PPIO into a specific use case?" and common issues like failed PPIO requests.
Design and build client-ready websites and mobile web apps in a working studio's proven house style, shown throughout on two fictional brands (AURA Heights, The Assembly): tinted grounds, editorial typography, obsessive specificity, and proof over promise. Carries the full working loop (brief, design contract, build, review gate, multi-lens audit, ship), two verified token systems, signature component patterns, proof-driven copywriting, real-photography rules, and a mobile web-app playbook (density budget, bottom tab bar, compaction). Trigger on "make it look expensive", "make it beautiful", "high end design", "client ready", "on brand professional", "use the prom design style", "design this landing page", "make it more like an app", "too much scrolling", "add real images", "the site looks cheap", "too generic", "ai slop". Not for inventing a fresh visual direction from a blank brief: this skill applies ONE proven aesthetic.
Repo Updater - Multi-repo synchronization with AI-assisted review orchestration. Parallel sync, agent-sweep for dirty repos, ntm integration, git plumbing. 17K LOC Bash CLI. Use when syncing multiple GitHub repositories, running agent-sweep on uncommitted changes, or orchestrating AI-assisted code review across repos.
Pair "what failed first" with "what finally worked" and codify the should-have-known-it insight as an ast-grep rule, a skill, or a CLAUDE.md rule. Meta-skill: invoke ONLY when the user explicitly says "codify today's lessons," "make it a skill," "drop it into lint," or asks to extract a reusable rule from a trial-and-error fix. Do NOT auto-invoke at every task completion. Spares future-you (or another agent) the same trap.
Reviews Rust test code for unit test patterns, integration test structure, async testing, mocking approaches, and property-based testing. Covers Rust 2024 edition changes including async fn in traits for mocks, #[expect] lint suppression, LazyLock test fixtures, and temporary scope changes affecting test assertions. Use when reviewing _test.rs files, #[cfg(test)] modules, or test infrastructure in Rust projects. Covers tokio::test, test fixtures, and assertion patterns.
Foundation reference for the Salla Admin (Merchant) API — base URL, Bearer-token auth, request headers, merchant identity, common resource endpoints, pagination, rate-limit tiers/headers, HTTP status codes with slugs, structured error shapes, and the App Settings read-modify-write pattern. Use whenever writing, reviewing, or debugging any Salla Admin API call — auth setup, pagination, error handling, app-settings read/write, or rate limits. Every other Salla skill builds on this; merchant token handling → salla-app-auth.
Programmatic SEO planning and analysis for pages generated at scale from data sources. Covers template engines, URL patterns, internal linking automation, thin content safeguards, and index bloat prevention. Use when user says "programmatic SEO", "pages at scale", "dynamic pages", "template pages", "generated pages", or "data-driven SEO".
Comprehensive OmniStudio / Salesforce Industries development skill covering OmniScripts, FlexCards, Integration Procedures, Data Mappers (DataRaptors), namespace detection, dependency mapping, and migration patterns. TRIGGER when: user works with OmniStudio components, asks about OmniScripts, FlexCards, Integration Procedures, Data Mappers, DataRaptors, namespace detection, or Vlocity-to-Core migration.
Writes, debugs, and art-directs procedural GLSL fragment shaders (Shadertoy mainImage, WebGL2 / GLSL ES 3.00): SDF raymarching, procedural buildings/cities, 2D distance-field graphics, noise / fBm / domain warping, terrain, ocean/coastal water optics, clouds and other volumes, PBR lighting, color and tonemapping. Ships a verified GLSL building-block library with a bundler and checker. Use when the user asks for a shader, Shadertoy, GLSL/.frag/.glsl code, a raymarcher, an SDF scene, a procedural texture or generative visual, or wants a shader fixed, optimized, ported or explained. Not for HLSL/Unity ShaderLab or non-graphics GPU compute.
Validate shell scripts for syntax errors, common bugs, quoting issues, and portability problems. Auto-detects shellcheck binary or guides installation. Checks project config or falls back to sensible defaults. Use when creating or modifying shell scripts, validating bash/sh files, or catching shell scripting mistakes before committing.
Found or continue a roadmap autopilot one stage per invocation. Default: human merge. --fullauto is invocation-scoped and uses the transient wrapper only after a fresh audit. Triggers: "ship-roadmap", "ship the roadmap", "autopilot this project".
Use when the current Spec Pack must be abandoned/revoked due to a major problem with the requirements, the corresponding `.aisdlc/specs/{branch}` directory and both local and remote branches must be deleted, and a deletion list must be output before performing the deletion with a request for the user's second confirmation.
Use when building batch jobs, ETL pipelines, scheduled imports/exports, or any chunk-oriented bulk processing with Spring Batch. Covers the Spring Batch 5 / Boot 3 builder API, restartability and idempotent job parameters, reader/writer thread-safety, fault tolerance, and chunk transaction boundaries.
Use when upgrading an existing Spring Boot application, for example from Boot 3.x to Boot 4 or to the latest Spring Boot and Java: dependency transitions and starter renames, test annotations such as @MockBean to @MockitoBean, Jackson 3 issues, Spring Modulith 2 or Testcontainers 2 upgrades, code that stops compiling after a version bump, or planning a phased migration. Not for greenfield project creation or isolated repository design.
Storybook (UI catalog) reference. story, CSF (Component Story Format), CSF Next (CSF Factories), args, argTypes, decorators, play function, interaction tests, autodocs, main.ts / preview.ts, add-ons (a11y, controls, viewport, themes), Vitest addon, test-runner, Storybook MCP server, components manifest, add-on creation, upgrade / migration.
Once the requirements, plan, or implementation code are settled, consolidate the requirement-compliant code, diffs, and module chains into specification documents under docs/spec/. Use when the user asks to summarize a module, consolidate a spec, update specifications, settle on the implementation definition, record the blast radius, current boundaries, or TODOs. Also applies when the user provides requirement/plan/implementation files and wants the final behavior synced to docs/spec.
Supabase (open source Firebase alternative, BaaS) reference. PostgreSQL database, Auth (Email / OAuth / Magic Link / Phone / SSO), Storage, Edge Functions (Deno), Realtime (subscriptions / presence / broadcast), Vector embeddings, supabase-js, supabase CLI, RLS (Row Level Security), migrations. Based on PostgreSQL. SQL Server / node-mssql is a separate skill, mssql.
Use this skill for Vue apps needing Excel-like UI using the Syncfusion Spreadsheet Component. Trigger for creating, viewing, editing Excel (.xlsx, .xls, .xlsb) and CSV files; embedding spreadsheet editors; data binding from APIs/JSON; using formulas, charts, validation, filtering, or conditional formatting. Also trigger when users reference spreadsheet files ("open xlsx", "load Excel file", "add Syncfusion spreadsheet", "bind data to spreadsheet"). Do NOT trigger for standalone file processing without UI components.
TypeScript type-checking workflow. Use this skill whenever the user works with TypeScript and mentions type errors, type checking, or says "类型检查" (type check), "type-check", "tsc", "检查类型" — even if they don't explicitly ask for a "type check" but are encountering compilation or type issues in a TypeScript project.
Creates new uni-app-x projects with Vue 3 + TypeScript + Vite via CLI or HBuilderX, including tsconfig.json setup, manifest.json and pages.json configuration, and Composition API project templates. Use when the user wants to scaffold a new uni-app-x project, initialize TypeScript project files, or set up the uni-app-x development environment.
New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
