Core coding standards and best practices for code review and generation. Provides KISS and measurable clean-code outcomes, guiding principles (DRY, YAGNI, SOLID), priority frameworks, tooling baselines, dependency management, and response formats. Use when reviewing code, generating code, asking about coding standards, or when the user needs general engineering guidance that applies across all languages.
Principal-level IAM and security architecture advisor for identity protocols, IGA, PKI, PAM, secrets delivery, and non-human identity. Use for architecture decisions, protocol deep dives, design reviews, threat models, or mentoring involving OAuth, OIDC, SAML, SCIM, mTLS, certificates, workload identity, or privileged access.
Structured development workflow with Plan/Implement/Review phases, QA validation, context management, and audit requirements. Enforces explicit authorization for remote mutations, risk-based checkpoints, and proportional audit reports. Use when working on complex tasks, multi-file changes, or when the user mentions planning, workflow, implementing features, or needs structured development guidance.
Databricks playbook. Workflows for workspace bootstrap, Unity Catalog migration, Lakeflow Spark Declarative Pipelines (formerly Delta Live Tables / DLT), Declarative Automation Bundles (formerly Databricks Asset Bundles), cluster policies/access modes, serverless SQL and jobs, Photon and cost tuning, governance audit, Mosaic AI/MLflow, and recovery via Delta time travel. Use when designing, operating, or auditing Databricks.
Documentation best practices including Markdown formatting, Mermaid diagrams, technical writing, ADRs, and open source standards. Use when writing documentation, README files, markdown content, creating static diagrams in Markdown, or when asking about documentation structure, technical writing, or open source project setup. For interactive React Flow canvases in a SPA, use the reactflow-architecture-diagrams skill instead.
Delivers narrative interactive architecture diagrams using React, TypeScript, Tailwind, and @xyflow/react (React Flow): node and edge patterns, optional Cloudflare orange shell grouping, routing, and verification. Use when adding or editing React Flow diagram components (Diagram.tsx suffix convention), files under components/diagrams, xyflow edges, animated canvas traffic, or when the user asks for a React Flow architecture diagram alongside documentation.
Bash scripting best practices for production-grade scripts, CLI tools, and Makefiles. Covers strict mode, error handling, portability, performance patterns, and argument parsing. Use when working with .sh files, Makefiles, shell scripts, or when asking about Bash, shell scripting, CLI design, or command-line tools.
Cloud platform best practices for AWS, Azure, GCP, and Cloudflare. Covers Zero Trust architecture, IAM patterns, EKS/AKS/GKE configurations, serverless patterns, and multi-cloud strategies. Use when working with cloud infrastructure, AWS services, Azure resources, GCP projects, Cloudflare Workers, or when asking about cloud architecture and deployment.
