Use jrnl as a persistent memory store to remember user information, preferences, project context, and facts across conversations. This skill should trigger whenever: the user shares personal information, preferences, or project details that would be useful to remember later; when you need to recall prior context about the user, their setup, or their work; when the user asks "do you remember..." or similar recall questions; when the user mentions storing, saving, or noting something for later; when discussing projects, tools, or workflows where knowing the user's history would improve your assistance. Always query relevant memories before answering questions about the user's projects, preferences, setup, or past conversations — even if you think you remember, the journal may have more current information.

Apply Rust-inspired safety patterns to TypeScript code. Use this skill whenever writing or reviewing TypeScript — especially when adding types, handling errors, validating external data (APIs, file input, user input), designing state machines, or refactoring legacy code with loose booleans or try/catch. It covers four patterns: discriminated unions (eliminate impossible states), Result types (explicit failures), schema-based parsing at boundaries (parse don't validate), and explicit mutability. If the user is working with TypeScript and mentions any of these concepts, or if their code shows patterns like boolean overloads, untyped throw, or unchecked external data, apply this skill.
