It is designed to assist with module design, state management, multi-cloud deployments (AWS, GCP, Azure), and CI/CD integration. It is particularly useful for designing reusable modules, managing remote backends, implementing multi-environment (dev/staging/prod) patterns, and troubleshooting state drift or plan failures.

  2. Overview of the Skill Logger skill

    main

    The Skill Logger is designed to track, measure, and improve skill quality through systematic logging and scoring. It specializes in skill analytics, quality metrics, feedback loops, and continuous improvement.

    When to Use

    • Setting up skill usage logging.
    • Defining quality metrics for skill outputs.
    • Analyzing skill performance over time.
    • Identifying skills that need improvement.
    • Building feedback loops for skill enhancement.
    • A/B testing skill variations.

    When NOT to Use

    • Creating new skills: Use agent-creator instead.
    • Skill documentation: Use skill-coach instead.
    • Runtime debugging: Use appropriate debugger skills.
    • General logging/monitoring: Use devops-automator.

  3. Overview of GitHub Actions Pipeline Builder skill

    main

    The github_actions_pipeline_builder skill is an expert agent designed to build production-grade CI/CD pipelines using GitHub Actions. It specializes in implementing matrix builds, dependency caching, automated deployments, testing, security scanning, and release workflows.

    Activation Keywords:

    • "GitHub Actions"
    • "CI/CD"
    • "workflow"
    • "deployment pipeline"
    • "automated testing"

    Capabilities:

    • Allowed Tools: Read, Write, Edit, Bash
    • Use Cases: Automated testing, staging/production deployments, Docker image building/publishing, release automation, security scanning, and code quality checks.
    • Constraints: Do NOT use for non-GitHub repositories (e.g., Jenkins, CircleCI) or complex pipelines better suited for dedicated CI/CD tools.

  4. Overview of Cloudflare Worker Dev skill

    main

    The Cloudflare Worker Dev skill is designed for developing with Cloudflare Workers, KV, Durable Objects, and edge computing. It is suitable for building serverless APIs, caching layers, rate limiting, and real-time features.

    Activation Keywords: "Workers", "KV", "Durable Objects", "wrangler", "edge function", "Cloudflare".

    Note: This skill is NOT intended for Cloudflare Pages configuration, DNS management, or general CDN settings.

  5. Overview of the Design Catalog

    main
    The Design Catalog is a comprehensive collection of over 700 design patterns organized into 38 JSON-based configuration files. It provides structured guidance for visual effects, content structures, interaction patterns, and domain-specific templates. Each entry in the catalog is designed to include real-world examples, bestFor use cases, accessibility considerations, and implementation guidance.

  6. Overview of the Planning Directory structure

    main

    The planning/ directory serves as a centralized repository for roadmaps, technical specifications, and implementation plans. It is organized by project subfolders to facilitate tracking progress and coordinating work across different skills or agents.

    Core Directory Structure:

    • /winamp-improvements/: Contains audio engineering upgrades for the Winamp music player, including ROADMAP.md, engineering recommendations, and implementation logs.
    • /photo-intelligence/: Contains research reports regarding photo analysis, AI curation, and semantic search features.
    • /docs/historical/: (Related) Contains historical migration logs and development archives.

  8. Overview of the Vaporwave MIDI Player Artifact

    main

    The Vaporwave MIDI Player is a preserved implementation of a Winamp-style music player designed with a vaporwave aesthetic. It features Windows 3.1 beveled borders, CRT glow effects, and a 24-bar visualizer. This artifact represents the initial implementation created by the vaporwave-glassomorphic-ui-designer skill and does not include advanced audio engineering enhancements like real-time FFT or reverb effects.

    Key Features

    • 22 MIDI Tracks: Includes 15 Blank Banshee tracks and 7 AI-generated tracks.
    • 8 Album Covers: Vaporwave aesthetic art.
    • 4 Theme Skins: Classic, Dolphin, Sailor Moon, and Vintage.
    • 24-Bar Visualizer: Animated frequency display.
    • Winamp UI: Includes title bar, display, controls, and visualizer layout.
    • Persistent Preferences: Uses LocalStorage to save skin selections.
    • Navbar Widget: A minified version of the player for site navigation.

  9. Overview of OAuth/OIDC Implementer skill

    main

    The oauth-oidc-implementer skill is an expert agent designed for implementing OAuth 2.0 and OpenID Connect (OIDC) authentication flows. It specializes in secure token handling, social login integration (e.g., Google, GitHub), API authorization, and identity provider configuration (e.g., Auth0, Okta, Keycloak).

    Use Cases

    • Implementing social logins.
    • Setting up OAuth 2.0 for API authorization.
    • Configuring OIDC for enterprise SSO.
    • Designing token refresh and session management.
    • Implementing PKCE for mobile/SPA applications.
    • Securing API endpoints with JWT validation.
    • Troubleshooting OAuth flow failures.

  10. Overview of the OAuth/OIDC Implementer skill

    main
    The OAuth/OIDC Implementer is an expert skill designed for implementing OAuth 2.0 and OpenID Connect (OIDC) authentication flows.

It covers both client-side and server-side flows using security best practices like PKCE.

  11. Overview of the Meta-Skills Experiment

    main

    The Meta-Skills Experiment is a study comparing the effectiveness of self-evaluation versus cross-evaluation in skill-building agents. The experiment pitted two agents against each other:

    1. skill-architect (WinDAGs' skill-building agent)
    2. skill-creator (Anthropic's skill-building agent)

    Key Findings

    • Cross-evaluation outperforms self-evaluation: Agents improving another agent's work (cross-improvement) resulted in higher composite scores and better adherence to quality metrics (like SKILL.md line counts and the presence of NOT clauses).
    • Blind spots: Self-evaluation often suffers from "phantom self-contamination," "blind spot inheritance," and "optimistic self-scoring," where the agent fails to catch its own structural or mathematical errors.

    Directory Structure

    • originals/: Baseline skills (SA0, SC0).
    • self-improved/: Skills improved by the agent itself.
    • cross-improved/: Skills improved by the other agent (Recommended).
    • evaluations/: Detailed evaluation reports and scoring data.

  12. Overview of Playwright E2E Tester skill

    main
    The playwright-e2e-tester is an expert skill for end-to-end testing using the Playwright framework. It is designed to assist with test generation, implementing the Page Object Model (POM), visual regression testing, and configuring CI/CD pipelines. It handles complex scenarios such as authentication flows, API mocking, and cross-browser testing (Chromium, Firefox, WebKit).
