Your creative muse for writing. Reads your journals, notes, and past work, taps into an optional Signal DB for real-time trends, searches the web — then surfaces topic ideas that are timely, authentic, and uniquely yours. Use when asked to "find a topic", "what should I write about", "inspire me", "topic ideas", "help me pick a topic", "选题", or "写什么好".

Apply this skill whenever designing, scaffolding, reviewing, or refactoring the architecture of a Next.js App Router + TypeScript + Tailwind + shadcn + Drizzle application. Triggers on requests like "how should I structure this", "where should this logic live", "scaffold a new feature", "review my folder structure", "plan this feature", "add a new module", or any time you're creating multiple files that need to fit together coherently. Use this skill proactively — do not make ad-hoc structural decisions without consulting it.

Use when setting up automated skill review pipelines, configuring CI/CD for Tessl skill scoring, adding PR checks for skills, or migrating between workflow architectures. Supports GitHub Actions, Jenkins, Azure DevOps, and CircleCI.

A lightweight RFC process for solo developers working with AI agents. Prevents premature complexity by forcing problem-first thinking before jumping to solutions. Use when the user is considering introducing new tools, libraries, architectural patterns, or infrastructure. When they're weighing a significant technical decision. Triggers on phrases like "should I add X", "I'm thinking about introducing Y", "is this overkill", "do I need X", "is X worth it", "/rfc", or when the user is about to adopt a tool/pattern without first articulating the problem it solves.

Use this skill any time a .pptx file is involved in any way — as input, output, or both. This includes: creating slide decks, pitch decks, or presentations; reading, parsing, or extracting text from any .pptx file (even if the extracted content will be used elsewhere, like in an email or summary); editing, modifying, or updating existing presentations; combining or splitting slide files; working with templates, layouts, speaker notes, or comments. Trigger whenever the user mentions "deck," "slides," "presentation," or references a .pptx filename, regardless of what they plan to do with the content afterward. If a .pptx file needs to be opened, created, or touched, use this skill.

Build UIs with Chakra UI components, layout primitives, and theming. Use when using Chakra UI, ChakraProvider, Box, Flex, Stack, or when the user mentions Chakra.

Implement Figma designs in code with accurate layout, spacing, typography, and tokens. Use when implementing designs from Figma, translating mockups to React/CSS, or when the user mentions Figma, design specs, or Dev Mode.

Apply Tailwind CSS utility-first styling, responsive design, and theming. Use when styling with Tailwind, building UI with utility classes, configuring tailwind.config, or when the user mentions Tailwind.

Drafts, edits, and adapts content to match Guy Podjarny's tone of voice — founder of Tessl and Snyk, co-host of the AI Native Dev podcast. Use when writing Tessl blog posts, Snyk-related communications, AI Native Dev content, or when the user requests Guy's voice, style, or tone for blog posts, social media, announcements, or long-form content.

Fastify patterns — schema-first validation, encapsulated plugins, hooks lifecycle, decorators, structured error handling, TypeScript type providers, async handler patterns, and production hardening with CORS, helmet, rate limiting, logging, and graceful shutdown. Use when building or reviewing Fastify APIs, when migrating from Express, or when setting up a new Node.js API with Fastify.

Every production-bound application MUST follow DevOps best practices from day one. This includes multi-stage Dockerfiles with non-root users, proper .dockerignore files, cache-efficient layer ordering, health checks, CI/CD pipelines with separate build/test/deploy stages, 12-factor configuration via environment variables, graceful shutdown handling, and secrets management. Apply this whenever creating Dockerfiles, docker-compose configurations, CI/CD pipelines, or deploying any application.

Security defaults that belong in every Go HTTP server from day one. CORS, security headers, rate limiting, input validation, SQL injection prevention, CSRF protection, TLS configuration, secrets management, graceful shutdown, and request timeouts. Apply these whenever you create or modify any Go web service -- do not wait for a security review or explicit request.

Production error handling patterns that must be included from day one in any Express API. Apply whenever building, extending, or scaffolding an Express backend -- even if the task only asks for routes or CRUD endpoints. These patterns prevent silent async crashes, inconsistent error formats, stack trace leaks, and dropped connections on deploy.

Build real-time betting and casino game platforms with PubNub

Run task evals across multiple Claude models, compare results side-by-side, and optimise. Use when you want to understand how a skill performs across different models, identify model-specific gaps versus universal tile issues, or validate a skill before publishing it to the registry.

Review and improve your SKILL.md with actionable recommendations. Reads skill bundle (SKILL.md + related docs), validates syntax, explains rubric, shows before/after scores. Use when reviewing skill quality, improving a skill file, checking skill scoring, making your skill better, or learning the skill rubric. This is the standalone review skill — for the full optimization cycle (review + evals + improve), use the `optimize-skill-performance-and-instructions` skill instead.

Run the full optimization cycle for a tile — review best practices, generate eval scenarios, run evals, diagnose gaps, fix, and re-run until scores improve. Use when someone says "optimize my skill", "improve my tile", "run evals", "benchmark my tile", or wants to measure and improve how well a tile helps agents solve tasks.
