Claude Skills

Use when designing incident management processes, creating runbooks, or establishing on-call practices. Covers incident lifecycle, communication, and postmortems.

Comprehensive Windows 11 system diagnostics via PowerShell. Diagnoses crashes, freezes, reboots, BSOD, disk health, memory issues, hardware errors, and performance problems. Use when troubleshooting Windows stability issues, analyzing Event Viewer logs, checking disk/memory health, investigating hardware errors, or diagnosing system performance problems.

Use when designing Internal Developer Platforms (IDPs), building platform teams, or improving developer experience. Covers platform engineering principles, Backstage, portal design, and platform team structures.

Problem solving using Fishbone (Ishikawa) diagrams and 5 Whys technique. Identifies root causes systematically and recommends corrective actions.

Risk analysis using risk registers, probability/impact matrices, and mitigation planning. Identifies, assesses, and manages project, business, and technical risks with structured response strategies.

Define team interfaces, contracts, and communication boundaries

USE WHEN: building web components, pages, or applications requiring distinctive visual design, user says "design", "UI", "frontend", "interface", or wants production-grade aesthetics. DO NOT USE WHEN: backend work, API development, simple scripts, or when generic styling is acceptable.

Design Thinking methodology for human-centered innovation. Covers the 5-phase IDEO/Stanford d.school approach (Empathize, Define, Ideate, Prototype, Test) with workshop facilitation and exercise templates.

End-to-end ML system design for production. Use when designing ML pipelines, feature stores, model training infrastructure, or serving systems. Covers the complete lifecycle from data ingestion to model deployment and monitoring.

Use when implementing service-to-service security, mTLS, or service mesh patterns. Covers mutual TLS, Istio, Linkerd, certificate management, and service mesh security configurations.

Decision guidance for selecting the right diagram type and tool. Provides patterns for common visualization scenarios, tool comparison, and best practices.

Authoritative reference for Mermaid diagram syntax. Provides diagram types, syntax patterns, examples, and platform integration guidance for generating accurate Mermaid diagrams.

Implement Go error handling patterns including error wrapping, sentinel errors, custom error types, and error handling conventions. Use when handling errors, creating error types, or implementing error propagation. Trigger words include "error", "panic", "recover", "error handling", "error wrapping".

OCaml fuzz testing with Crowbar for protocol implementations. Use when Claude needs to: (1) Write fuzz tests for parsers and encoders, (2) Test roundtrip invariants (parse(encode(x)) = x), (3) Verify boundary conditions and error handling, (4) Test state machines and transitions, (5) Organize fuzz test suites for large codebases

Provides production-ready Kubernetes manifest guidance including resource management, security, high availability, and configuration best practices. This skill should be used when working with Kubernetes YAML files, deployments, pods, services, or when users mention k8s, container orchestration, or cloud-native applications.

Decision modeling using decision tables, weighted scoring matrices, and decision trees. Structures complex decisions with clear criteria, alternatives evaluation, and outcome prediction.

OCaml memtrace profiling for allocation hotspot analysis. Use when Claude needs to: (1) Add memtrace instrumentation to OCaml executables, (2) Run targeted benchmarks with tracing enabled, (3) Identify allocation hotspots from trace output, (4) Optimize code to reduce boxing and allocations, (5) Validate optimizations with before/after comparisons

Analyzes project dependencies for known security vulnerabilities using npm audit, pip-audit, or similar tools. Use when auditing packages, checking for CVEs, or updating vulnerable dependencies.

Manages Terraform state operations including importing existing resources, moving resources between states, removing resources from state, and migrating state backends. This skill should be used when users need to import infrastructure into Terraform, refactor resource addresses, fix state issues, or migrate state storage locations.

Migrating OCaml projects from ocamlbuild/topkg to dune. Use when discussing _tags files, .mllib files, pkg/pkg.ml, topkg, or build system migration.

Optimize CI/CD pipelines for speed, reliability, and efficiency. Use when improving build times, fixing pipeline failures, or enhancing deployment processes.

Generates conventional commit messages by analyzing git diffs and changes. Use when writing commit messages, following commit conventions, or documenting changes.

Scans Docker images for security vulnerabilities, outdated packages, and misconfigurations. Use when checking image security, finding vulnerabilities, or hardening containers.

Publishing OCaml to npm via js_of_ocaml and wasm_of_ocaml. Use when discussing browser targets, JavaScript compilation, WASM output, npm packages, or the two-branch workflow.
