Tools & Utilities
Essential command-line tools and system utilities.
feature-writer
Guides users through defining features via adaptive discussion and generates structured feature 1-pagers. Use when users want to create a well-documented feature request or need help articulating a feature idea. The discussion is conversational, not a form - follow threads, ask follow-ups, and refine until the user is satisfied.
vercel-design-guidelines
Check web interfaces against Vercel's design guidelines. Use when asked to "review my UI", "check accessibility", "audit design", "review UX", "check my site against best practices", or "apply Vercel design guidelines".
system-spec-kit
Unified documentation and context preservation: spec folder workflow (levels 1-3), template enforcement, validation, Spec Kit Memory with vector search, six-tier importance system, constitutional rules, checkpoint save/restore. Mandatory for all file modifications.
confluence
Confluence documentation including pages, spaces, templates, and Atlassian integration. Activate for wiki pages, documentation, knowledge bases, and team collaboration.
build-tanstack-app
Build and enhance React applications using the TanStack ecosystem. Use this skill when working with TanStack libraries such as Router, Query, Form, or Table—whether starting a new project or integrating into existing code.
doc-coauthoring
Guide users through a structured workflow for co-authoring documentation. Use when user wants to write documentation, proposals, technical specs, decision docs, or similar structured content. This workflow helps users efficiently transfer context, refine content through iteration, and verify the doc works for readers. Trigger when user mentions writing docs, creating proposals, drafting specs, or similar documentation tasks.
notion-sync
Use when syncing Obsidian notes to Notion, pushing notes to Notion, pulling from Notion, setting up Notion sync, or mentioning Notion integration with the vault.
deploying-to-aws
Specialized skill for deploying Next.js applications to AWS using SST (Serverless Stack) or Vercel, with DynamoDB integration, IAM configuration, and infrastructure as code. Use when setting up AWS resources or deploying production applications.
project-scaffolding
Project type detection matrix, template recommendations per project type, post-scaffolding checklist, Harness integration patterns, and testing recommendations
pipeline-phase-guide
Intelligently navigate the 7-phase Spec Kit → CCGC workflow by detecting current phase, validating prerequisites, recommending transitions, and tracking per-project state. Use when the user asks "what phase", "what's next", "workflow steps", "guide me through pipeline", or phase keywords like "specify", "plan", "tasks", "implement", "validate", "sync". Essential for multi-project developers maintaining context across different features and codebases simultaneously.
encore-vercel-deploy
Automates deployment of Encore.ts backend and Next.js frontend to Encore Cloud and Vercel. Use this skill when deploying the full-stack application, setting up new environments, or troubleshooting deployment issues.
github-pages-docs
Create and maintain GitHub Pages documentation for administrative guides, ubiquitous language definitions, and domain-driven design artifacts. Use when writing or updating documentation for admin procedures, domain terminology, DDD concepts, or user guides that will be published to GitHub Pages.
generate-working-docs
開発作業ドキュメントを自動生成します。YYYYMMDD_要件名の形式でディレクトリを作成し、requirements.md、design.md、tasklist.md、testing.mdを生成します。「開発作業ドキュメント作成」「新規開発のドキュメント作って」「ドキュメント生成」などで呼び出されます。
obsidian-vault-ops
Read and write Obsidian vault files, manage wiki-links, process markdown with YAML frontmatter. Use when working with vault file operations, creating notes, or managing links.
cicd-github-actions-dev
Develop and troubleshoot GitHub Actions workflows and CI configurations. Use when creating workflows, debugging CI failures, understanding job logs, or optimizing CI pipelines.
nextjs
Build, review, and refactor Next.js (App Router) frontend projects with TypeScript. Use for tasks like creating pages/layouts, routing, server components vs client components, data fetching patterns, UI component structure, forms/validation, auth integration points, env vars, linting/testing, and production deployment readiness.
nx-docs-writer
Documentation writing and editing for nx.dev docs. Use when adding, editing, or polishing documentation, migrating Markdoc to Starlight, debugging content transformations, or fixing documentation site issues. Triggers on "docs", "documentation", "nx.dev", "Markdoc", "Starlight", "astro-docs".
antigravity-memory
Create and optimize MEMORY.md memory files or .agent/rules/ modular rules for Antigravity projects. Comprehensive guidance on file hierarchy, content structure, path-scoped rules, best practices, and anti-patterns. Use when working with MEMORY.md files, .agent/rules directories, setting up new projects, or improving Antigravity's context awareness.
doc-coauthoring
Guide users through a structured workflow for co-authoring documentation. Use when user wants to write documentation, proposals, technical specs, decision docs, or similar structured content. This workflow helps users efficiently transfer context, refine content through iteration, and verify the doc works for readers. Trigger when user mentions writing docs, creating proposals, drafting specs, or similar documentation tasks.
