Create tessl tiles containing docs, rules, or skills. Use when a user wants to create a tile, package content for tessl, or needs help with tile.json configuration. Also triggers on "create tile from", "convert to tile", "turn into tile", "make tile from", or "tile this repo" for existing content.

Append context-aware next-step suggestions after every agent response. Generates actionable follow-ups, surfaces unfinished tasks from memory, and includes at least one creative lateral suggestion. Self-learns user preferences for count, categories, and format. Use when: (1) any response is generated and nextsteps is active, (2) user says /nextsteps, "next steps", "what should I do", "suggestions", "what now", (3) user wants to customize suggestion count, categories, or format, (4) user says "disable next steps" or "enable next steps".

Prisma ORM patterns — schema design, migrations, type-safe queries, relations, transactions, connection pooling, error handling, testing, raw SQL safety, and performance. Use when building or reviewing apps with Prisma, when setting up a new database with Prisma, when writing tests for Prisma-backed code, or when debugging query performance.

Apply SOLID principles, detect design anti-patterns, and evaluate architectural tradeoffs for code reviews, design decisions, and refactoring. Use when reviewing code for maintainability issues, evaluating architecture decisions, identifying code smells and technical debt, or refactoring modules with coupling or testability problems.

Execute a strict Red-Green-Refactor TDD cycle for a single requirement at a time, in any language or framework. Use when the user provides a business rule, acceptance criterion, or feature requirement and wants a failing test written first, followed by minimum implementation, then a clean refactor. Works for unit tests, integration tests, UI component tests, and API tests across stacks including TypeScript, JavaScript, React, .NET (C#/xUnit/NUnit), Python, Java, and others. Triggered by phrases like "write a test first", "TDD", "red-green-refactor", "behavioral test", "test-driven", "failing test first", or "write the test before the code".

Extract actionable insights and valuable artifacts from web posts, articles, and technical documentation. Use when summarizing content, extracting key ideas from URLs/articles, preserving code snippets and diagrams, or creating visual summaries. Triggers on requests like "summarize this post", "extract insights from", "distill this article", "what are the key takeaways", or when a URL is shared for analysis.
