Coding standards, frameworks, refactoring, and code review (18.5K skills)
This entry points users to the current skill for building Article Pages. It contains no page construction rules itself; use the successor skill to create a new page.
This entry no longer contains instructions for building Feature Pages. That guidance has moved to the `page-builder` skill in Pagina; use that successor when you want an agent to create a new Feature Page.
This entry no longer contains rules for building a Migration Page. The guidance has moved to Pagina’s page-builder skill; use that skill when you need to create a new Migration Page.
This entry directs users to the current skill for building Breadcrumb components. It includes no component rules itself; use the successor skill when creating a new Breadcrumb.
This compatibility entry points to the current skill for building a Blog Index. It contains no page-building rules and is no longer maintained; use the successor page-builder skill for new Blog Index work.
This deprecated compatibility entry no longer contains Footer building rules. It directs users to the `component-builder` skill in Bricks, where Footer construction is maintained, and suggests using that skill to create a new Footer.
This deprecated compatibility entry no longer contains rules for building Tabs and Accordion components. That guidance has moved to the component-builder skill in Bricks; use the successor to have an agent create a new component.
This deprecated compatibility entry directs users to the current way to build a How-to Section. It contains no component rules or construction steps; use the component-builder skill maintained in Bricks for new sections.
Plan favicon and app icon assets for browser tabs, bookmarks, mobile home screens, and Google Search listings. The skill recommends sizes and formats, provides implementation notes for common site setups, and checks crawlability and PWA manifest needs.
This entry points users who need a new Modal to the successor component-builder skill, where Modal construction is maintained. It contains no component-building rules itself, so it serves only as a compatibility notice for the moved guidance.
This entry redirects users creating a new Testimonials component to Bricks' `component-builder`. It contains no component-building rules itself, so use the maintained successor for instructions and construction guidance.
This compatibility entry directs users to the current skill for building a Carousel component. It includes no component rules and is no longer maintained; use the successor component-builder skill when creating a new Carousel.
Use this skill to guide Rust backend work with Axum and Tokio. It provides practical conventions for error handling, async code, module structure, performance, and tests, helping keep implementation choices consistent across a web service.
Use this skill to review time handling in application code, database fields, APIs, and deployments. It helps make business time zones explicit when reading the current time, calculating day or month boundaries, or comparing timestamps across zones.
Use this skill to review Go code against conventions for naming, error handling, concurrency, testing, and performance. It helps keep implementations consistent and maintainable, and activates when working with .go, go.mod, or go.sum files.
Use this skill to spot common performance risks in database and service queries, including N+1 calls, oversized IN clauses, unbounded tree traversal, and repeated nested service queries. It provides checks and patterns for batching, limiting, and reusing results.
Review user-driven large exports and batch serialization for memory use, temporary-file cleanup, request blocking, and spreadsheet formula injection. The guidance helps choose streaming or asynchronous output, apply size limits, and handle formats such as Excel, CSV, JSON, JSONL, and PDF safely.
Apply practical safety and performance rules to Redis code, including replacing blocking KEYS queries with SCAN, limiting large values, batching requests with Pipeline, and assigning TTLs so keys expire automatically.
Set up the cc-use-exp configuration for Codex CLI by downloading its repository and syncing Codex rules, instructions, profiles, and skills. Run it again to check for an existing installation and update it.
Apply practical Python conventions for style, type hints, error handling, and efficient code. The guide also explains when to use asyncio for concurrent I/O, semaphores to limit concurrency, generators for large data, and multiprocessing for CPU-heavy work.
Apply consistent conventions to Bash scripts and system commands, including quoted variables, explicit paths, safe file writing, and logging for complex commands. The guidance helps keep scripts easier to follow and maintain.
Review application, database, and deployment time zone handling to prevent date and reporting mismatches between environments. It guides explicit time zone use, consistent database settings, and safe comparisons across zones, with examples for several programming languages.
Use this skill to build and maintain Rust backend web services with Axum and Tokio. It provides guidance on project structure, error handling, asynchronous code, dependencies, tests, and unsafe blocks, helping keep implementation choices consistent across a service.
Review the current code changes or a specified commit in quick, full, or security mode. The skill prioritizes bugs, regression risks, validation and error handling gaps, security concerns, and weak tests, then presents findings with file references and remaining uncertainties.
