Claude Skills

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.

PROACTIVE skill - Claude invokes automatically when user messages exhibit anti-patterns. Detects recursive nesting, scope creep, buried asks, assumed context, stream dumps, imprecise descriptions. Disable with "coach off" or "raw mode".

Design composable prompt sections for building agentic prompts. Use when creating reusable prompt components, designing LEGO-block prompt sections, or structuring prompts for the stakeholder trifecta.

Guide selection of appropriate prompt level for a task. Use when choosing between simple prompts and complex workflows, applying the seven levels framework, or matching task complexity to prompt investment.

Audit current context composition and identify optimization opportunities. Use when context window is overloaded, agents are underperforming, or applying the R&D framework to optimize token usage.

Design user-facing agent experts for adaptive UX and personalization. Use when building product features that learn from user behavior, creating per-user expertise files, or implementing AI-driven personalization.

Apply R&D framework to optimize prompts and context. Use when optimizing context window usage, reducing prompt size, delegating to specialized agents, or applying systematic context management.

Design E2E tests following user-story-driven patterns with verification checkpoints. Use when creating end-to-end tests, validating complete user journeys, or designing Playwright/Cypress test patterns.

Design custom agents from scratch using Claude Agent SDK patterns. Use when building domain-specific agents, designing agents with full SDK control, or creating specialized agents with custom tools and prompts.

USE WHEN: writing system prompts, structuring complex instructions, engineering context for Claude agents, optimizing attention efficiency in long prompts. DO NOT USE WHEN: writing regular code, simple messages, or content where Markdown suffices. For optimal context architecture, trigger deep thinking with "think harder" or "ultrathink" to analyze attention economics thoroughly.

Four fundamental team types and interaction modes from Team Topologies

Design memory hierarchy with progressive loading for optimal context management. Use when organizing CLAUDE.md imports, implementing just-in-time context loading, or designing priming hierarchies for agents.

Align architecture and team structure using inverse Conway maneuver

Team interaction modes and their evolution over time

USE WHEN: user wants to publish, port, or share a skill to a marketplace repo. DO NOT USE WHEN: creating new skills, installing skills, or general questions.

Apply systematic test case design techniques including equivalence partitioning, boundary value analysis, decision tables, and state transition testing.

Guides through Terraform version upgrades including identifying deprecated syntax, updating provider versions, and migrating breaking changes. This skill should be used when users need to upgrade Terraform or provider versions, fix deprecated warnings, or migrate configurations to newer syntax.

Implement data quality checks, validation rules, and monitoring. Use when ensuring data quality, validating data pipelines, or implementing data governance.

Manage Python dependencies using UV, pip-tools, or requirements.txt. Use when setting up dependency management, resolving conflicts, or choosing between UV, pip-tools, and requirements.txt workflows.
