research-ts-decisions
Research why the TypeScript team made a specific typing decision. Use when evaluating whether ts-reset should override a built-in type, or when triaging issues that propose type changes. Searches the microsoft/TypeScript repo for relevant issues, PRs, and team comments.
webiny-admin-website-builder-catalog
admin/website-builder — 59 abstractions.
ppt-template-creator
Creates self-contained PPT template SKILLS (not presentations) from user-provided PowerPoint templates. Use ONLY when a user wants to create a reusable skill from their template. For creating actual presentations, use the pptx skill instead.
building-and-verifying
Use when building the Nango monorepo or verifying TypeScript compilation - covers build commands, project references, common tsc errors, and package dependency order
frontend-design
Design thinking and decision-making for web UI. Use when designing components, layouts, color schemes, typography, or creating aesthetic interfaces. Teaches principles, not fixed values.
nanogpt
Educational GPT implementation in ~300 lines. Reproduces GPT-2 (124M) on OpenWebText. Clean, hackable code for learning transformers. By Andrej Karpathy. Perfect for understanding GPT architecture from scratch. Train on Shakespeare (CPU) or OpenWebText (multi-GPU).
prompt-optimization
Guides building, reviewing, and optimizing system prompts and prompt templates for LLMs. Use when creating system prompts, writing prompt templates, optimizing prompt structure, reducing prompt token usage, compressing prompts, improving prompt clarity, reviewing prompts for safety and bias, or making prompts more token-efficient. Also use when the user says "write a prompt," "optimize this prompt," "system prompt," "prompt engineering," "make this prompt better," "reduce tokens," or "compress this prompt."
mz-run
This skill should be used when the user wants to "run Materialize locally", "start environmentd", "check compilation", "format code", "lint", "cargo check", "cargo fmt", "cargo clippy", "bin/fmt", "bin/lint", or mentions compiling, building, running, formatting, linting, log filters, jemalloc, or CockroachDB setup in the Materialize repository. Use this skill even if the user just says "how do I run this" or "it won't compile" without being specific.
paper-illustration
Generate publication-quality AI illustrations for academic papers using Gemini image generation. Creates architecture diagrams, method illustrations with Claude-supervised iterative refinement loop. Use when user says "生成图表", "画架构图", "AI绘图", "paper illustration", "generate diagram", or needs visual figures for papers.
proof-writer
Writes rigorous mathematical proofs for ML/AI theory. Use when asked to prove a theorem, lemma, proposition, or corollary, fill in missing proof steps, formalize a proof sketch, 补全证明, 写证明, 证明某个命题, or determine whether a claimed proof can actually be completed under the stated assumptions.
paper-figure
Generate publication-quality figures and tables from experiment results. Use when user says "画图", "作图", "generate figures", "paper figures", or needs plots for a paper.
proof-writer
Writes rigorous mathematical proofs for ML/AI theory. Use when asked to prove a theorem, lemma, proposition, or corollary, fill in missing proof steps, formalize a proof sketch, 补全证明, 写证明, 证明某个命题, or determine whether a claimed proof can actually be completed under the stated assumptions.
dashboard-testing
Guide for writing tests for the Aspire Dashboard. Use this when asked to create, modify, or debug dashboard unit tests or Blazor component tests.
debug-generated-project
Debugs issues users encounter with Tuist-generated projects by reproducing the scenario locally, building Tuist from source when needed, and triaging whether it is a bug, misconfiguration, or something that needs team input. Use when users report generation failures, build errors after generation, or unexpected project behavior.
using-tuist-generated-projects
Guides day-to-day work in Tuist-generated Xcode workspaces, including generation, build and test commands, and buildable folders. Use when working in a Tuist-generated project or when users mention `tuist generate`, `xcodebuild test`, or generated workspaces.
authoring-errors-and-warnings
Guides authoring of MSBuild errors, warnings, and diagnostic messages. Consult when adding new MSBxxxx codes, writing or modifying user-facing diagnostic text, deciding between error/warning/message severity, working with Strings.resx resource files, formatting paths in error output, or evaluating whether a new warning could break WarnAsError builds.
reviewing-msbuild-code
Reviews MSBuild code changes using a 24-dimension methodology. Activates for code review, PR review, pull request analysis, design review, architecture review, code quality assessment, or style check of MSBuild code. Covers backwards compatibility, ChangeWave discipline, performance, allocation awareness, test coverage, error message quality, logging, string comparison, API surface, target authoring, cross-platform correctness, code simplification, concurrency, naming, SDK integration, evaluation model integrity, correctness, dependency management, security, and build infrastructure.
moonbit-agent-guide
Guide for writing, refactoring, and testing MoonBit projects. Use when working in MoonBit modules or packages, organizing MoonBit files, using moon tooling (build/check/test/doc/ide), or following MoonBit-specific layout, documentation, and testing conventions.
userinterface-wiki
UI/UX best practices for web interfaces. Use when reviewing animations, CSS, audio, typography, UX patterns, prefetching, or icon implementations. Covers 11 categories from animation principles to typography. Outputs file:line findings.
python-design
Python design patterns for CLI scripts and utilities — type-first development, deep modules, complexity management, and red flags. Use when reading, writing, reviewing, or refactoring Python files, especially in .trellis/scripts/ or any CLI/scripting context. Also activate when planning module structure, deciding where to put new code, or doing code review.
create-skill-from-source-code
Analyze existing source code to identify key patterns and generate comprehensive educational skill documentation with proper YAML frontmatter, architectural analysis, code templates, and usage examples.
