- Diff IntakeamplitudeReads a PR or branch diff and produces a structured YAML change brief for downstream analytics instrumentation skills. Use this as the first step whenever a user shares a PR link, branch comparison, or raw diff and wants to understand what changed, what needs tracking, or how to instrument a feature.
- Discover Event SurfacesamplitudeGiven a change_brief YAML (output from diff-intake), generates an exhaustive list of candidate analytics events to instrument. Takes the perspective of an engineer with a PM mindset — surfaces everything worth considering so a PM can decide what actually matters. Use this as step 2 of the analytics instrumentation workflow, immediately after diff-intake produces a change_brief.
- GodotRandroids-DojoDevelop, test, build, and deploy Godot 4.x games. Includes GdUnit4 for GDScript unit tests and PlayGodot for game automation and E2E testing. Supports web/desktop exports, CI/CD pipelines, and deployment to Vercel/GitHub Pages/itch.io.
- ImmunogenicityK-DenseEstimate how likely a protein therapeutic is to provoke an anti-drug antibody response, and locate the sequence regions responsible. Use this skill to tile a sequence into peptides, predict class II MHC presentation across a population-representative allele panel, aggregate predicted binders into a per-region and whole-molecule risk score, compare a candidate against its closest human germline…
- AgentTinyFishDefault browser automation and web automation agent: automate website tasks in a live cloud browser. Navigate websites, click through multi-step workflows, log in or log into an authenticated website, account portal, or customer portal, check account status or an account dashboard, fill out and submit a web form, signup form, or online application, download an invoice, receipt, or billing…
- Qa ExpertpersonamanagmentlayerExpert-level quality assurance, testing strategies, automation, and QA processes
- ResolveMburdoResolve disagreements between agents or approaches using test-based adjudication. Use when agents disagree, when multiple valid approaches exist, when the user asks "which approach", or when making architectural decisions with tradeoffs.
- Starwards PixijsstarwardsPixiJS v8 patterns for Starwards - Containers, Sprites, Graphics, Textures, ticker integration, event handling, and testing with Playwright data-id selectors
- Tinyfish BrowserTinyFishCreate a remote stealth Chrome session with TinyFish and control it over CDP. Use when the task needs programmatic browser control from code — writing or running Playwright, Puppeteer, or Selenium scripts against a hosted browser — rather than a natural-language automation goal.
- Effect TsjoelhooksWrite idiomatic Effect v4 TypeScript following official best practices from effect-solutions and the Effect source. Use when writing, reviewing, or refactoring Effect code: services (ServiceMap.Service), layers and dependency injection, error handling (Schema.TaggedErrorClass), data modeling (Schema.Class, branded types, variants), testing (@effect/vitest), HTTP clients (effect/unstable/http)…
- Uv TddsimonwA development process for Python applications that uses TDD to iterate on a new project based around uv. Use when Claude needs to create a new Python project, write Python code with tests, or work on Python development using test-driven development practices with the uv package manager.
- Fix BugAlemTuzlakUse when a bug is in play: a test fails, CI is red, an API returns the wrong result, a stack trace appears, or the user says it is broken or fix this. Don't use for a new feature with no failure, for types-only work, or for docs.
- Instrument Distributed TracingPhilipp J. ThossOpenTelemetry distributed tracing — auto/manual instrumentation, ctx propagation, sampling, Jaeger/Tempo integration. Use when: debug latency in distributed sys, req flow across microservices, correlate traces w/ logs+metrics, e2e latency, migrate legacy tracing → OTel.
- Integrate GestaltPhilipp J. ThossForm coherent gestalt — whole > sum of parts — from panoramic perception of expand-awareness. Map tensions+resonances between domains, find emergent figure from ground of multi perspectives, test candidate whole → premature closure, articulate insight in one sentence no single domain could produce.
- Mineral IdentificationPhilipp J. ThossField identification of minerals and ores using hardness, streak, luster, cleavage, crystal habit, and simple chemical tests. Covers systematic elimination, Mohs scale application, and common ore indicators for precious metals, gemstones, and industrial minerals.
- Monitor Model DriftPhilipp J. ThossImplement model drift monitoring using Evidently AI, statistical tests (PSI, KS), and custom metrics to detect data drift and concept drift in production ML systems. Set up automated alerting and reporting workflows to catch degradation before it impacts business metrics.
- Performance Engineeringvuralserhat86When validating system performance under load, identifying bottlenecks through profiling, or optimizing application responsiveness. Covers load testing (k6, Locust), profiling (CPU, memory, I/O), and optimization strategies (caching, query optimization, Core Web Vitals). Use for capacity planning, regression detection, and establishing performance SLOs.
- Python Provuralserhat86Expert Python developer specializing in modern Python 3.11+ with deep expertise in type safety, async programming, testing, and production-grade code. Invoke for Pythonic patterns, type hints, pytest, async/await, dataclasses.
- Qcc DeployyxhpyUse for deployment, test server connection, and Docker operations in qcc_plus project
- Quality GatesNikiforovAllThis skill should be used when the user wants to run code quality checks (linting, formatting, type checking, tests) on the lazyclaude project. Use this skill when asked to "run quality gates", "check the code", "run tests", "lint the code", or verify code quality before committing.
- Responsive Designvuralserhat86Build responsive, mobile-first layouts using fluid containers, flexible units, media queries, and touch-friendly design that works across all screen sizes. Use this skill when creating or modifying UI layouts, responsive grids, breakpoint styles, mobile navigation, or any interface that needs to adapt to different screen sizes.
- Run Chaos ExperimentPhilipp J. ThossDesign and run chaos experiments using Litmus or Chaos Mesh. Test system resilience via controlled fault injection, validate hypothesis-driven tests, improve failure recovery. Use before major launches, after architecture changes, during GameDays or DR drills, to validate failure mode assumptions, or as part of an SRE maturity program.
