Retrieve and investigate API metrics and request log data from Apitally. Fetches aggregated metrics, request logs, consumers, and app metadata via the Apitally CLI, stores data in a local DuckDB database, and runs SQL queries to investigate issues or answer questions. Use when the user mentions Apitally, the Apitally CLI, API metrics, API request logs, or API consumers.

Generate executable code together with formal proofs certifying safety and correctness properties in Isabelle/HOL or Coq. Use when building verified software, safety-critical systems, or when formal guarantees are required. Produces code with accompanying proofs for memory safety, bounds checking, functional correctness, invariant preservation, and termination. Supports extraction to OCaml/Haskell/SML and integration with existing codebases.

Trigger with phrases like "clay production", "clay go-live", "clay launch checklist", "clay production readiness", "deploy clay pipeline".

Execute use when you need to work with backup and recovery. This skill provides backup automation and disaster recovery with comprehensive guidance and automation. Trigger with phrases like "create backups", "automate backups", or "implement disaster recovery".

Create banners using AI image generation. Discuss format/style, generate variations, iterate with user feedback, crop to target ratio. Use when user wants to create a banner, header, hero image, cover image, GitHub banner, Twitter header, or readme banner.

Comprehensive guide for creating software diagrams using Mermaid syntax. Use when users need to create, visualize, or document software through diagrams including class diagrams (domain modeling, object-oriented design), sequence diagrams (application flows, API interactions, code execution), flowcharts (processes, algorithms, user journeys), entity relationship diagrams (database schemas), C4 architecture diagrams (system context, containers, components), state diagrams, git graphs, pie charts, gantt charts, or any other diagram type. Triggers include requests to "diagram", "visualize", "model", "map out", "show the flow", or when explaining system architecture, database design, code structure, or user/application flows.

rlang metaprogramming for tidy evaluation and non-standard evaluation (NSE) in R. Use when building data-masking APIs, wrapping dplyr/ggplot2/tidyr functions with {{ !! !!! operators, implementing quosures and dynamic dots, or designing tidyverse-style DSLs—e.g., "tidy eval wrapper function", "embrace operator usage", "NSE programming patterns", "custom select helpers".

This skill enables Claude to execute visual regression tests using tools like Percy, Chromatic, and BackstopJS. It captures screenshots, compares them against baselines, and analyzes visual differences to identify unintended UI changes. Use this skill when the user requests visual testing, UI change verification, or regression testing for a web application or component. Trigger phrases include "visual test," "UI regression," "check visual changes," or "/visual-test".

This skill generates comprehensive test reports with coverage metrics, trends, and stakeholder-friendly formats (HTML, PDF, JSON). It aggregates test results from various frameworks, calculates key metrics (coverage, pass rate, duration), and performs trend analysis. Use this skill when the user requests a test report, coverage analysis, failure analysis, or historical comparisons of test runs. Trigger terms include "test report", "coverage report", "testing trends", "failure analysis", and "historical test data".

This skill runs smoke tests to verify critical application functionality. It executes pre-defined test suites that check system health, authentication, core features, and external integrations. Use this skill after deployments, upgrades, or significant configuration changes to ensure the application is operational. Trigger this skill using the terms "smoke test" or "st".

Configure Juicebox local dev workflow. Trigger: "juicebox local dev", "juicebox dev setup".

Implement environment and configuration management with comprehensive guidance and automation. Use when you need to work with environment configuration. Trigger with phrases like "manage environments", "configure environments", or "sync configurations".

Generates professional slide deck images from content. Creates outlines with style instructions, then generates individual slide images. Use when user asks to "create slides", "make a presentation", "generate deck", "slide deck", or "PPT".

Posts content and articles to X (Twitter). Supports regular posts with images/videos and X Articles (long-form Markdown). Uses real Chrome with CDP to bypass anti-automation. Use when user asks to "post to X", "tweet", "publish to Twitter", or "share on X".

Turborepo monorepo build system guidance. Triggers on: turbo.json, task pipelines, dependsOn, caching, remote cache, the "turbo" CLI, --filter, --affected, CI optimization, environment variables, internal packages, monorepo structure/best practices, and boundaries. Use when user: configures tasks/workflows/pipelines, creates packages, sets up monorepo, shares code between apps, runs changed/affected packages, debugs cache, or has apps/packages directories.

Design multi-stage CI/CD pipelines with approval gates, security checks, and deployment orchestration. Use this skill when designing zero-downtime deployment pipelines, implementing canary rollout strategies, setting up multi-environment promotion workflows, or debugging failed deployment gates in CI/CD.
