Expert guidance for unix-goto shell navigation tool development, including architecture, 9-step feature workflow, testing (100% coverage), performance optimization (<100ms targets), and Linear issue integration
Set up monitoring with error tracking, alerts, dashboards, and SLOs for production applications. Use when user says "set up monitoring", "add error tracking", "create alerts", "observability", "SLOs", "health checks", "how do I know if it's broken", or needs production visibility.
Generalised autonomous optimisation loop — soft RLVR for any artifact a user can measure. Web runtime package: uses memory in this order: connector-backed, project-pack, none. Never assumes subprocess access or unrestricted local files. Use this skill whenever a user wants to iteratively improve an artifact — code, prompts, documents, configs, designs, content — by running structured experiments, evaluating results against a multi-dimensional rubric, and learning from each attempt. Triggers include: "optimise this", "keep improving until it's good", "run experiments on", "autoresearch", "iterate on this overnight", "try different approaches and pick the best", or any request implying repeated evaluate-and-improve cycles.
VRChat UdonSharp で重い再構築処理、replay、reset、段階実行、分割適用が必要な runtime を設計・実装するときに使う。大量オブジェクト更新、操作列の再適用、1 フレームで終わらない処理を安全に扱いたい場合に使う。
Improve interface resilience through better error handling, i18n support, text overflow handling, and edge case management. Use when user says "harden this", "handle edge cases", "error handling", "i18n support", "make it robust", "production-ready", or when an interface needs to handle real-world conditions.
Implementing idiomatic, safe, and performant Rust code.
How to define and use defineErrors from wellcrafted. Use when creating new error types, updating error definitions, or reviewing error patterns. Covers variant factories, extractErrorMessage for cause, InferErrors/InferError for types, and call site patterns.
Generate JavaScript code for Max js objects (V8) and Node for Max scripts (N4M)
REST and GraphQL API architect for designing robust, scalable APIs. Use when designing new APIs or improving existing ones.
VRChat UdonSharp の再利用モジュールを Builder First で立ち上げるときに使う。Runtime と Editor の責務分離、project-owned なドキュメント整備、シーン生成前提の構成、外部プロジェクトへ持ち出せる基本骨格が必要な場合に使う。文書雛形の配布そのものは `vrc-udon-project-docs`、ネットワーク仕様の固定は `vrc-udon-networking-rules` に分ける。
外部の VRChat UdonSharp プロジェクトに project-owned な AGENTS.md、README、SYSTEM_SPEC、SCENE_OBJECT_SPEC、ENVIRONMENT_SETUP、OFFICIAL_REFERENCE_MAP を配布可能な形でそろえるときに使う。実装前の文書土台、環境再現用の文書セット、U# Program Asset 自動生成用の Editor テンプレート、必要なら Unity MCP 用 `.mcp.json` テンプレートを作りたい場合に使う。モジュール構造そのものは `vrc-udon-core-module` に分ける。
Deploy a project to Vercel with proper configuration, environment variables, domains, and preview deployments. Use when user says "deploy to Vercel", "set up Vercel", "configure deployment", "add a domain", "preview deploys", or needs to ship a project to production.
Create distinctive, production-grade frontend interfaces with high design quality. Use this skill when the user asks to build web components, pages, or applications. Generates creative, polished code that avoids generic AI aesthetics.
Internal skill. Use cc10x-router for all development tasks.
Internal skill. Use cc10x-router for all development tasks.
Guidance for asking clarifying questions when user requests are ambiguous, have multiple valid approaches, or require critical decisions. Use when implementation choices exist that could significantly affect outcomes.
