Implement robust input validation with server-side checks, client-side UX feedback, specific error messages, allowlist strategies, and consistent validation across all entry points. Use this skill when validating user input in web forms, API endpoints, or background jobs; when implementing server-side validation for security and data integrity; when adding client-side validation for immediate user feedback; when validating data types, formats, ranges, and required fields; when providing clear, field-specific error messages; when implementing allowlist strategies instead of blocklists; when sanitizing user input to prevent injection attacks (SQL, XSS, command injection); when validating business rules at the appropriate application layer; when applying validation consistently across web forms, API endpoints, and background jobs; or when designing validation architecture for security and user experience.

Global Validation

This Skill provides Claude Code with specific guidance on how to adhere to coding standards as they relate to how it should handle global validation.

When to use this skill

When validating on the server side for security and data integrity
When using client-side validation to provide immediate user feedback
When validating input early and rejecting invalid data before processing
When providing clear, field-specific error messages
When implementing allowlist strategies instead of blocklists
When checking data types, formats, ranges, and required fields
When sanitizing user input to prevent injection attacks
When validating business rules at the appropriate application layer
When applying validation consistently across all entry points

agent-browser

shynlee04/idumb-v2

Browser automation CLI for AI agents. Use when the user needs to interact with websites, including navigating pages, filling forms, clicking buttons, taking screenshots, extracting data, testing web apps, or automating any browser task. Triggers include requests to "open a website", "fill out a form", "click a button", "take a screenshot", "scrape data from a page", "test this web app", "login to a site", "automate browser actions", or any task requiring programmatic web interaction.

gap-analysis

shynlee04/idumb-v2

Systematically identify what's missing, unknown, or needs investigation before making changes or decisions. Use proactively when proposing features, implementing changes, or making technical decisions to ensure all critical areas are covered. This skill catches overlooked dependencies, edge cases, and integration points before they become problems. Examples: - "Implement user authentication" → trigger gap analysis (what's the current auth system?) - "Add caching to API" → trigger gap analysis (what caching infrastructure exists?) - "Migrate to TypeScript" → trigger gap analysis (what's the build pipeline?) - "Refactor this module" → trigger gap analysis (what depends on this module?) - "Add new API endpoint" → trigger gap analysis (what endpoints exist, what patterns?)

intent-clarification

shynlee04/idumb-v2

Detect ambiguous or underspecified research requests and guide through structured clarification questions before executing any research. Use proactively when user requests are vague, lack specificity, missing context, or have unclear goals. This skill prevents wasted research by ensuring intent is crystal clear before any web searches, file reads, or data gathering. Examples: - "Research the codebase" → ❌ Too vague, trigger clarification - "Why is this slow?" → ❌ Missing context (what is "this"?), trigger clarification - "Add a feature" → ❌ Not research, this is implementation - "Investigate authentication flow" → ❌ What specifically about it? Trigger clarification - "Compare React and Vue" → ✅ Specific enough, but still validate dimensions

multi-aspect-assessment

shynlee04/idumb-v2

Evaluate requests, proposals, or decisions from multiple dimensions (technical, business, UX, security, performance, maintainability, etc.) to ensure holistic understanding before proceeding. Use proactively when making technical decisions, choosing solutions, or proposing changes. This skill prevents single-minded thinking and uncovers trade-offs, risks, and opportunities across all relevant aspects. Examples: - "Use Redis for caching" → assess multiple aspects (performance, cost, complexity, ops) - "Add AI to our app" → assess aspects (technical feasibility, user experience, data privacy) - "Refactor to microservices" → assess aspects (benefits, costs, migration complexity, team readiness) - "Implement authentication" → assess aspects (security, UX, integration effort, maintenance) - "Switch to React 19" → assess aspects (benefits, migration cost, breaking changes, learning curve)

opencode-primitive-selector

shynlee04/idumb-v2

Choose the right OpenCode primitive (Command, Skill, Tool, Prompt, CustomTool, Plugin hook) for a given task or workflow. Use proactively when deciding which OpenCode capability to use, or when trying to understand what's available. This skill maps research and development needs to appropriate OpenCode mechanisms, ensuring optimal use of the platform's capabilities. Examples: - "How do I search the codebase?" → select tool (read/grep) - "I need a reusable workflow for feature development" → select command - "How do I intercept file writes?" → select plugin hook - "What primitive should I use for systematic debugging?" → select skill - "I need a custom tool for X" → select CustomTool (if innate tools insufficient)

research-workflow-planner

shynlee04/idumb-v2

Create structured, executable research plans with clear phases, checkpoints, and validation criteria. Use proactively when research intent is clear but execution plan is missing. This skill transforms research goals into actionable workflows with defined deliverables, time estimates, and success metrics, ensuring research is systematic and produces useful outputs. Examples: - "Research how to add OAuth" (intent clear, need plan) → trigger workflow planner - "Investigate performance bottlenecks" (intent clear, need plan) → trigger workflow planner - "Analyze codebase architecture" (intent clear, need plan) → trigger workflow planner - "Find best practices for X" (intent clear, need plan) → trigger workflow planner - "Compare technology options" (intent clear, need plan) → trigger workflow planner
