Topos Institute's CatColab for collaborative category theory - community model building, double theories, stock and flow epidemiology, and real-time collaborative diagramming via Automerge CRDT.
Modern C# development with .NET 8+, async patterns, and records. Use when: - Writing or reviewing C# code - Configuring async/await with ConfigureAwait - Using nullable reference types - Implementing pattern matching - Setting up .NET projects Keywords: C#, .NET, async, await, ConfigureAwait, nullable, record, pattern matching, xUnit, ValueTask
Design systems with appropriate complexity—no more, no less. Use this skill when the user asks to architect applications, design system boundaries, or make structural decisions. Generates pragmatic architectures that solve real problems without premature abstraction.
Game server design patterns including ECS, command pattern, and event sourcing
Maximally isolated Signal authentication via colored operad security boundaries. VM→Container→Process enclosure with GF(3) conservation for Agent-O-Rama pathways.
Go concurrency patterns. Routes to specific patterns.
Example skill demonstrating embedded hooks for validation and logging
Concurrent agent dispatch for independent problems. Use when facing multiple independent tasks that can be worked on simultaneously. Reduces total time by parallelizing work that has no shared state.
Guide for creating high-quality MCP (Model Context Protocol) servers
Critical architecture knowledge for the squared component library package. Use this skill when working on squared package components, troubleshooting build/transpilation issues, or setting up apps to consume squared. Covers the NO BUILD STEP architecture, CSS Modules-only styling requirement, Next.js transpilation configuration, direct TypeScript source exports, and testing infrastructure.
Coalgebraic observation of derivation streams with final coalgebra bisimulation
Debug and fix failures in Taskcluster tasks. Use this skill when the user asks to debug a task, fix a failing task, or investigate task errors/failures. This skill uses the Taskcluster CLI to fetch task logs and definitions, analyzes errors, and uses `taskgraph load-task --develop` to reproduce and debug issues locally. Invoke this for any request involving Taskcluster task debugging, task failures, or when given a task ID to investigate.
Expert knowledge in modern web development best practices, patterns, and industry standards. Covers code quality, design patterns, version control, documentation, code review, CI/CD, error handling, and state management. Use when establishing coding standards or reviewing code architecture.
Ruby and Rails best practices for services, testing, and architecture. Use when: - Writing or reviewing Ruby/Rails code - Designing service objects or organizing business logic - Setting up RSpec tests with FactoryBot - Building APIs with JSON serialization - Optimizing Rails performance (N+1, caching) Keywords: Ruby, Rails, RSpec, FactoryBot, service object, strong params, N+1 query, Sidekiq, RuboCop, Thor CLI
Capture solutions as patterns for future use. Activate when you fix a bug, solve a non-trivial problem, get corrected by the user, discover something that works (or doesn't work), find a better approach, or complete any solution worth remembering. Failures are just as valuable as successes - forge anti-patterns too.
为新入职员工或代码审查者生成结构化的代码阅读路径指南。自动分析项目架构,识别技术栈和分层结构,按照从上层到底层的顺序生成渐进式阅读计划。适用场景:(1)新员工项目onboarding,(2)代码审查准备,(3)系统重构前分析,(4)技术债务评估。支持Java/Spring、Node.js、Python等常见技术栈。
Collaborative terminal session sharing using CRDT-style s-expressions
處理跨 Bounded Context 的依賴關係。當需求涉及多個限界上下文（如權限管理、付款、通知）時觸發，設計 Anti-Corruption Layer 和 Context Mapping。
Prevent goroutine leaks with proper shutdown mechanisms
Use when encountering failures - assess severity, preserve evidence, execute rollback decision tree, and verify post-recovery state
Python development principles and decision-making. Framework selection, async patterns, type hints, project structure. Teaches thinking, not copying.
