Download the PDF of an academic paper (by DOI, publisher/doi.org URL, arXiv id, Anna's Archive md5, or title) with `paper-fetch`, the single paper-acquisition tool, including its browser fallback for challenge-protected hosts. Use whenever the user wants a paper, article, preprint or its PDF obtained, fetched, downloaded, saved or attached, even if they only paste a DOI or link, mention Anna's Archive, Sci-Hub, LibGen, PhilPapers or Unpaywall, or ask why a paper download failed. Not for books...

Release one of Pablo's Emacs packages, prepare its release notes, or audit release candidates. Use for release-package and package-release/readiness requests; preserve read-only or preparation-only scope and use release-dotfiles for the dotfiles repository.

Use when working on the SSOT docs (docs/NN_NN_*.md) — editing or creating a canon doc, hunting or fixing SSOT drift, adding or hardening a docs linter / CI gate, checking where a fact canonically lives, or publishing canon to the GitHub wiki. Operational playbook for docs:check_refs / docs:toc / tracker:check / wiki:sync, plus §Guard-craft — the craft of building a gate that actually catches: the recipe for adding a gate, its thesis, design rules, mutation-verify pitfalls, hardening checklist...

Use when working on the silken_net frontend — the Phlex component tree (app/views/components/ + shared/ui|iot|web3/), the Tailwind v4 @theme design-token system (gaia-* surfaces/text, status-*, token-* blockchain, gaia-input-*), the ApplicationComponent base (the tokens() TailwindMerge wrapper + class-autoscoped t() i18n + Turbo-broadcast-safe delegated helpers), the Stimulus controllers, and Turbo Streams/Frames. Knows the non-obvious gotchas — NO tailwind.config.js (SSOT = app/assets/tailwi...

Use when working on the SEC.3 factory-flashing pipeline — provisioning per-device keys into an STM32 at manufacture (app/services/factory_flashing/, lib/tasks/factory.rake): the one-pass silicon UID→DID derivation [FW.54], the wrong-board guard, UID collision → quarantine, the six Flash key blocks and their magics, word→big-endian byte order [FW.30], the chain-hashed audit trail, and the 2-Person supervisor rule. ⚠️ Гілка B = Гілка A + SE identity: its runtime keys go to Protected Flash throu...

Use when updating dependencies in ANY domain of this polyglot repo — Ruby gems (Gemfile/Gemfile.lock), the Ruby version itself, bundler, CI workflow actions (.github/workflows), JS/importmap, the conda ML + in-silico envs (tools/ml, tools/in_silico), the firmware C submodules (firmware/extern), the Terraform providers (terraform/*.tf required_providers), the .NET NuGet pins of tools/cad (Directory.Packages.props — PicoGK), the Solidity/Foundry contracts (OpenZeppelin/solc/forge-std), the subg...

排查 Spring ApplicationContext / Bean / 配置注入等问题

Use when 检查 CinderX 安装、初始化和最小 JIT 是否可用。

Use when 在 ARM64/Linux 大核主机按 NUMA/L3 隔离并行运行 CinderX pyperformance 或生成 dry-run 计划。

Use when 对 CinderX 的 Arm/x86 性能差异做 ISA、微架构与 perf 归因。

Use when 校验 CPython/CinderX lab 的版本、ABI、源码和 worker 环境是否可复用。

Use when 为 CPython/CinderX A/B 实验分配 CPU、容器和结果目录，判断能否并行。

Write type-safe TypeScript code with strict mode enabled, comprehensive type definitions, proper error handling, and elimination of any types. Use when enabling TypeScript strict mode, adding types to existing JavaScript, fixing type errors, creating type definitions, using utility types, implementing type guards, avoiding any types, creating generic types, or ensuring complete type safety across the codebase.

Implement test-driven development (TDD) workflow using the red-green-refactor cycle. Use when writing new features, fixing bugs, or refactoring existing code. Always write the failing test first, then implement minimal code to pass, then refactor. Essential for ensuring code reliability, preventing regressions, improving design through testability requirements, documenting expected behavior through tests, enabling confident refactoring, and maintaining high code quality standards throughout t...

Create consistent, scalable design systems using Tailwind CSS utility classes with custom themes, design tokens, and responsive design patterns. Use when building design systems, implementing custom themes, creating reusable utility patterns, configuring Tailwind theme extensions, implementing dark mode, building responsive layouts, creating design tokens, using arbitrary values, or establishing consistent spacing and typography scales.

Build beautiful, accessible UI components using shadcn/ui library with Radix UI primitives and Tailwind CSS styling that you own and can customize. Use when creating accessible component libraries, implementing common UI patterns (dialogs, dropdowns, tooltips), building forms with validation, creating data tables, implementing command palettes, using Radix UI primitives, customizing components with Tailwind, or building design systems with full ownership of code.

Improve code structure, readability, and maintainability without changing external behavior through systematic refactoring techniques like extracting functions, removing duplication, simplifying conditionals, and applying design patterns. Use when reducing technical debt, extracting functions or classes, removing code duplication, simplifying complex conditionals, renaming for clarity, applying design patterns, improving code organization, reducing coupling, increasing cohesion, or maintainin...

Implement React Server Actions in Next.js 14+ for secure, progressively enhanced form handling and server mutations without API routes. Use when handling form submissions, performing server-side mutations, implementing progressive enhancement, creating actions that work without JavaScript, validating data on the server, revalidating cached data after mutations, handling file uploads server-side, implementing optimistic UI updates, or building forms that gracefully degrade without client-side ...

Optimize application performance through code splitting, lazy loading, caching strategies, bundle size reduction, render optimization, and profiling. Use when improving page load times, reducing bundle sizes, optimizing React rendering, implementing code splitting, configuring caching strategies, lazy loading components and routes, optimizing images and assets, profiling performance bottlenecks, implementing virtual scrolling for large lists, or improving Core Web Vitals and Lighthouse scores.

Build efficient React applications using Next.js Server Components that render on the server, reducing client bundle size, improving performance, and enabling direct database access. Use when fetching data server-side, reducing JavaScript bundle size, accessing databases directly in components, implementing streaming with Suspense, creating layouts that only render once, optimizing Core Web Vitals, or building SEO-friendly applications with server-first architecture.
