agentcore-public-stack

Angular 21 development with modern best practices including signals, standalone components, reactive patterns, and accessibility. Use when creating Angular components, services, templates, or performing any Angular frontend development work. Covers TypeScript strict typing, signal-based state management, reactive forms, lazy loading, ng-icon setup, and Tailwind styling.

AWS CDK infrastructure development with TypeScript. Use when creating or modifying CDK constructs, DynamoDB tables, ECS/Fargate services, Lambda functions, S3 buckets, networking, IAM roles, or any CloudFormation resources. Covers configuration patterns, single-stack architecture, naming conventions, and Bedrock AgentCore integration.

CORS configuration across all CDK stacks, GitHub Actions workflows, and Python backends. Use when modifying CORS origins, adding new stacks that need CORS, debugging CORS errors in deployed environments, or touching any workflow env vars related to CDK_DOMAIN_NAME or CDK_CORS_ORIGINS.

Cut a new release of this monorepo. Use whenever the user wants to make, cut, ship, or prep a release, bump the version, or update RELEASE_NOTES.md / CHANGELOG.md — e.g. "let's cut a release", "make a new release", "bump the version and update the release notes", "ship the next version". Covers the release-branch workflow, the pre-merge DynamoDB GSI check, the SemVer bump + version sync, identifying what changed across the divergent main/develop histories, writing the changelog and release notes sized to the release, the squash-merge PR into main, and the required backmerge into develop.

Create distinctive, production-grade frontend interfaces with high design quality. Use this skill when the user asks to build web components, pages, artifacts, posters, or applications (examples include websites, landing pages, dashboards, Angular components, HTML/CSS layouts, or when styling/beautifying any web UI). Generates creative, polished code and UI design that avoids generic AI aesthetics.

Weekly Friday early-morning external + internal scan for emerging functionality, agentic trends, tools, and feature/UX improvements in the AgentCore Public Stack repo. Tracks AWS Bedrock + AgentCore announcements, Strands Agents releases, FastMCP (used by externally hosted MCP servers), the aws-samples/sample-strands-agent-with-agentcore reference repo, the MCP ecosystem (including MCP Apps + extensions), frontier model announcements, agent-harness patterns (including opencode (anomalyco/opencode) as an open-source coding-agent harness reference scanned through tooling, cost-effectiveness, and context-engineering lenses — releases-first, light touch), agentic UI/UX patterns (MCP Apps, Vercel AI SDK, assistant-ui, NN/g AI research, Linear/Cursor/Anthropic product blogs), and LibreChat as a parallel open-source agentic-platform reference (releases-first, light touch). Audits internal signals (recent commits, open PRs, CI failures, version-pin lag, dormant skills). Outputs a dated research doc + queues ideas in `docs/kaizen/review-queue.md` for that same morning's `kaizen-review-prep` (runs ~4 hours later) to rank into decisions. Opens a PR into `develop`. **Out of scope**: security advisories / Dependabot / CodeQL — those have dedicated tooling and don't need a weekly kaizen lens. Triggers: "kaizen research", "weekly research scan", "external scan", "what should we look at this week".

Friday late-morning synthesis. Runs ~4 hours after `kaizen-research` the same morning. Consumes this week's research doc, open items in `docs/kaizen/review-queue.md`, the outcomes of the prior review's proposals (read from merged PRs and from open PR branches), and recent merges/reverts/CI signal — produces a ranked, decision-oriented agenda. Every item has a Ship / Decline / Defer recommendation. Opens a PR into `develop`. Triggers: "kaizen review prep", "weekly review prep", "friday review", "rank kaizen ideas".

Tailwind CSS v4.1 best practices with WCAG 2.1 AA accessibility, theming, and dark mode support. Use when working with HTML, CSS, styling components, accessibility (a11y), WCAG compliance, color contrast, focus states, screen readers, theming, light mode, dark mode, or building accessible UI patterns like buttons, forms, cards, and navigation. Complements the angular-best-practices skill for Angular frontends.
