Define a set of actionable design principles that guide decision-making and resolve trade-offs.
Use this skill when building Python desktop applications using PySide6 with strict MVC architecture where all UI is defined by .ui files. Covers architecture patterns, controller/model/view separation, signal handling, and .ui file workflows.
Generate SOX sample selections, testing workpapers, and control assessments. Use when planning quarterly or annual SOX 404 testing, pulling a sample for a control (revenue, P2P, ITGC, close), building a testing workpaper template, or evaluating and classifying a control deficiency.
Define responsive layout grid systems with columns, gutters, margins, and breakpoint behavior.
Interactive skill for eliciting, formalizing, and persisting DynamoDB access patterns. Use when the user wants to start designing a DynamoDB table, define entities, or document how their application will read and write data. This is Step 1 of a 3-step pipeline: access patterns -> table design -> query interfaces. The output is a structured .md file that feeds into the dynamodb-table-design skill.
Use when defining stopping rules for projects, avoiding sunk cost fallacy, setting objective exit criteria, deciding whether to continue/pivot/kill initiatives, or when users mention kill criteria, exit ramps, stopping rules, go/no-go decisions, project termination, sunk costs, or need disciplined decision-making about when to quit.
Walk through the full process of building a digital health app — from defining the need through planning to implementation.
Behavioral compliance testing for any CLAUDE.md or agent definition file. Auto-generates test scenarios from your rules, runs them via LLM-as-judge scoring, and reports compliance. Optionally improves failing rules via automated mutation loop.
Go error handling patterns: wrapping with context, sentinel errors, custom error types, errors.Is/As chains, and HTTP error mapping. Use when implementing error returns, defining package-level errors, creating custom error types, wrapping errors with fmt.Errorf, or checking errors with errors.Is/As. Use for "error handling", "fmt.Errorf", "errors.Is", "errors.As", "sentinel error", "custom error", or "%w". Do NOT use for general Go development, debugging runtime panics, or logging strategy.
Use when creating new skills, commands, or agent definitions for Claude Code, including writing SKILL.md files, defining triggers, and testing skill behavior
Create or update a RootSpec specification — interview-driven with built-in validation and derived artifact generation. Use this when a user wants to define, expand, revise, or reinterpret their product specification, add features, or edit any spec level.
Trigger: Call this skill when the task you are facing clearly requires collaboration of multiple ideological tools. Common trigger signals include: starting a new project from scratch, tackling complex and difficult problems, iterating and optimizing existing solutions. This skill provides standardized cross-skill workflow combinations to solve the problem of "which skill to use first and how to connect them". English: Trigger when a task clearly requires multiple skills in sequence. Use this skill to select a standard workflow that chains skills together, defines data handoff between steps, and specifies termination conditions.
