Development
Performs structured analysis of RFP (Request for Proposal) or requirement documents, identifying stakeholders, functional modules, system constraints, and generating key clarification questions. This Skill focuses on 'analysis and decomposition' to prepare for subsequent User Story writing.
Profile before optimizing, cut allocation out of hot paths, and treat LTO, codegen-units, PGO and target-cpu as the last five percent. Use when Rust code is too slow, when a benchmark regresses, when reviewing code that allocates or formats inside a loop, when release-profile or codegen flags come up, or when the user asks how to make Rust faster.

This skill should be used when users want guidance on Spec-Driven Development methodology using GitHub's Spec-Kit. Guide users through executable specification workflows for both new projects (greenfield) and existing codebases (brownfield). After any SDD command generates artifacts, automatically provide structured 10-point summaries with feature status tracking, enabling natural language feature management and keeping users engaged throughout the process.
Comprehensive backend development skill for building scalable backend systems using NodeJS, Express, Go, Python, Postgres, GraphQL, REST APIs. Includes API scaffolding, database optimization, security implementation, and performance tuning. Use when designing APIs, optimizing database queries, implementing business logic, handling authentication/authorization, or reviewing backend code.
Guides senior front-end software engineering—TypeScript/React/Next.js architecture, component design, client and server rendering, state and data fetching, styling and design systems, accessibility (WCAG), performance (Core Web Vitals), testing, and senior-level UI code review. Use when building or refactoring complex UIs, designing component APIs, optimizing LCP/INP/CLS, implementing accessible interactions, integrating design tokens, or reviewing front-end PRs—not for backend APIs or databases (fullstack-software-engineer, senior-fullstack-developer), design-only critiques without implementation, CI/CD (devops), or cross-service system RFCs (senior-software-engineer). For implementing screens from design specs, component states, and visual QA, use ui-software-engineer. Deep perf investigations and load/RUM analysis: performance-engineer.
Expert-level agent skills for the entire ServiceNow development ecosystem. Covers Fluent SDK metadata (.now.ts), legacy scripting (GlideRecord, Script Includes, Client Scripts, g_form), and CLI setup (now-sdk auth, build, install). Use when generating, reviewing, or explaining any ServiceNow code.
Reusable UI blocks built with SGDS components and utilities that can be mixed and matched inside any page template. Use this skill whenever a user asks about app layout, application shell, page structure, sticky header, masthead placement, mainnav placement, footer placement, sgds-container, sgds-container-sidebar, simple app layout, sidebar app layout, dashboard layout, filter panel, sidebar filter, category filter, checkbox filter, or any self-contained UI section — even if they don't name it a 'block'. These are drop-in sections and shell structures, not full pages. Compose them with sgds-pattern-page-templates to build complete pages.
Conduct a complete feature pipeline from idea to PR — interactive framing, specification, and task planning up front, then autonomous design-gated, test-driven, reviewed delivery per task. Use when the user says ship this, ship it, run the full pipeline, build this feature end to end, take this from idea to PR, or wants autonomous execution after an approved plan. Do not use for single small edits, pure reviews, or pure diagnosis — invoke the specific skill instead.

Apply SOLID principles to write flexible, maintainable, and testable code. Use when designing classes, interfaces, and module boundaries. Covers Single Responsibility, Open/Closed, Liskov Substitution, Interface Segregation, and Dependency Inversion with practical TypeScript examples and detection heuristics.
Conversational design workshop for substantial work. Interviews the human one question at a time, explores 2-3 approaches with trade-offs, and presents the design section by section for approval before writing only design.md, then stops. Combines requirements discovery with codebase research and architecture design. Use when the user explicitly requests a spec or when atelier-orchestrator selects a Spec-backed Plan. Ambiguous design or discovery requests route through atelier-orchestrator.
Enforces spec-before-code workflow for AI-driven development. Automatically selects Spec-Kit or OpenSpec mode, triages complexity (quick/standard/thorough), recovers session context, and applies quality gates (G0-G4) with inline self-review at every stage. Use this skill whenever the user says "/super-spec", "spec first", "规范先行", or starts any feature, bugfix, or refactor — especially in projects with .spec-mode, .specify/, or openspec/ directories. Even if the user doesn't explicitly ask for spec-driven workflow, activate this skill for any non-trivial code change to prevent skipping the design phase. Orchestrates: Spec-Kit (v0.7.1, Workflow Engine) / OpenSpec (OPSX v1.2.0) + planning-with-files (v2.30.0) + ui-ux-pro-max (v2.5.0, 67 styles, 161 palettes, 14 stacks, 6 specialist skills) + Superpowers (v5.0.7, inline self-review, subagent model selection) + MemPalace (v3.3.0, 29 MCP tools, cross-session memory, knowledge graph).
