Coding standards, frameworks, refactoring, and code review (18K skills)
Use this skill to define recurring Trigger.dev tasks with cron schedules, set time zones and environments, and manage schedules through code or the dashboard. It also explains schedule payloads and common conditions that prevent a task from running.
Write Trigger.dev v4 tasks with validated inputs, scheduled runs, retries, waits, and task-to-task triggers. The skill explains how to handle Result values returned by waiting for tasks and highlights patterns that the v4 SDK does not support.
Use this skill to investigate failed SDK generation from an OpenAPI spec. It helps classify errors, identify likely root causes, and outline whether an overlay can address them, the spec needs changes, or a human decision is required.
Set up Better Auth for TypeScript applications, including server and client configuration, database adapters, sessions, email and social sign-in, and plugins. The guide also highlights environment variables, schema generation, and security settings to review.
Create, apply, and validate OpenAPI overlay files to customize SDK generation without editing the source specification. Use JSONPath to target operations or schemas and configure naming, grouping, retries, pagination, headers, enum handling, or custom security.
Apply the project’s core rules when changing TypeScript code: use Bun for package tasks, prefer the design system, validate external data without unsafe types, and follow conventions for data fetching and UI state. Run type and lint checks after changes.
Review specified files for outdated hook and API patterns, then replace them with the prescribed SWR hooks, API clients, or server API calls. The guidance covers data fetching, mutations, cache updates, and response handling, followed by a typecheck command.
Structure data fetching so server pages provide initial data to client components, while SWR refreshes it and handles mutations through an API client. The guidance covers cache keys, server and client responsibilities, and URL based organization context.
Review changed code after implementation for readability, repeated logic, inconsistent patterns, unsafe boundary handling, redundant casts, and dead code. The checklist guides cleanup and calls for a TypeScript type check after fixes.
Create and maintain Cursor rules in `.mdc` files. Learn how frontmatter, glob patterns, and automatic or manual application control which guidance applies, plus ways to organize rules and troubleshoot rules that do not apply or conflict.
Apply consistent TypeScript and React practices for safer data handling, component structure, state, and file organization. The guidance also covers readable code, accessible interactions and forms, event naming, and user feedback with Sonner toasts.
Guide API endpoint changes so request DTOs, runtime validation, OpenAPI documentation, and MCP tool metadata stay aligned. It covers discoverability, authentication, uploads, long-running tasks, and response types that MCP tools cannot handle.
Prepare an isolated worktree for a feature, ticket, or bugfix by following the repository’s setup conventions for environment files, databases, dependencies, and development servers. It also explains how to avoid conflicts when multiple worktrees are active.
Review old Git worktrees and their related Postgres databases, classify which appear safe to remove, and present recommendations before cleanup. The process checks branch and pull request status, local changes, and unpushed commits to protect work that may still be needed.
Keep Prisma schema changes, database migrations, and generated client types in sync across applications. The guidance also sets conventions for readable, prefixed CUID IDs, including short unique prefixes and the required database function cast.
Get guidance for package and dependency work in a bun-based monorepo. It covers package boundaries, cross-package imports, build commands, type checks, linting, and the structure for adding a new package.
Follow a consistent Speakeasy CLI workflow for SDK and OpenAPI tasks: check the CLI’s current capabilities first, use command help instead of guessing syntax, complete the task, and submit feedback about the experience afterward.
Use this skill to add Redis-based rate limiting to a TypeScript application. It covers SDK setup and basic usage, then points to guidance on algorithms, features, pricing, and traffic protection so you can choose and apply an appropriate limiter.
Visually inspect desktop frontend component changes by mounting them in a temporary Vite page. This lets you check the rendered UI in a browser without starting the Tauri app or a live model, then clean up the temporary harness files.
Coordinate multiple AI agents working on a large software project in parallel. The skill uses Git tasks and worktrees to let agents claim work, share progress, and contribute changes, with scripts and a dashboard for monitoring and control.
Read a text file from a given path so an agent can inspect configuration values, review code, or analyze data. It uses UTF-8 encoding and is intended for text files; binary files need separate handling.
Retrieve detailed instructions for a specified MCP server, including its capabilities, tool usage guidance, examples, and best practices. Use the returned information to learn how that server works and how to apply its tools in a task.
Modify an existing file by replacing an exact text match with new text, optionally changing every match. This focused editing method supports Windows and Unix line endings and is suited to small, targeted updates such as renaming a function or variable.
Search file contents across directories with a regular expression and get matching lines with their file paths and line numbers. Filter by filename, ignore case, limit results, or include nearby context. It uses Python and needs no external search tools.
