Coding standards, frameworks, refactoring, and code review (18.6K skills)
Review a GitHub pull request for fix-worthy bugs, regressions, security or performance risks, edge cases, and missing tests. The skill focuses on changes in the PR, ranks findings by severity, and returns a concise recommendation without automatically submitting the review.
Use this skill when preparing a Git commit. It reviews staged changes only, applies simplification findings when relevant, drafts a concise message that explains the reason for the change, checks whether the README needs updating, and completes the commit workflow.
Prepare and publish a pull request with a clear title, reviewer-ready summary, and evidence from completed checks. It guides branch and diff review, handles existing pull requests appropriately, and verifies the published title and body.
Clean up local Git branches that no longer exist on the remote. The workflow prunes remote references, checks for worktrees tied to gone branches, removes those worktrees first, then deletes the branches and reports what changed.
Use this skill to set up or troubleshoot Cloudflare email workflows. It helps choose between Workers bindings and the REST API, process incoming mail, configure domains, and review delivery practices for transactional email.
Use this skill to structure voice and chat agents built with LiveKit Agents. It helps plan for low latency, divide work across agents and focused tasks, and keep application state, approvals, and external actions under code control while the model interprets conversation meaning.
Set up or troubleshoot GitHub CLI authentication. Check whether `gh` is logged in, guide browser-based login, verify the active account, and address common failures such as missing repository access, stale authentication, or an outdated CLI.
Look up current LiveKit documentation before answering product-specific questions or writing code. Check API signatures, CLI flags, configuration, supported models, changelogs, pricing, and repository examples using the Docs MCP server or `lk docs`.
Use this skill to build or maintain Cloudflare Sandbox apps on the stable `@cloudflare/sandbox` package. It helps with isolated Linux environments driven by Workers, while keeping the package and container image on the matching stable release line.
Use this skill to expose an existing page workflow as experimental WebMCP tools. It creates an initialization script and deterministic checks, validates visible UI effects and safe failure behavior, and compares the tools with accessibility-tree automation when an external agent is available.
Turn browser traffic captured in a HAR file, a record of web requests and responses, into a standalone client, CLI, or library. Use it to inspect a site's internal API and automate repeated workflows with direct HTTP calls.
Use this skill to review unresolved pull request feedback, fix valid code issues across matching locations, and draft concise replies for comments that need no code change. It can identify the relevant pull request from a supplied reference or the current branch.
Build, debug, or review applications built with Cloudflare’s Agents SDK and the `agents` package. It covers agent state, routing, chat, scheduled and durable work, and integrations, while consulting current Cloudflare documentation for implementation details.
Prepare Blender assets for Unreal Engine FBX import by checking centimeter scale, naming, LODs, UCX collision meshes, sockets, materials, and skeletal mesh setup. The skill includes import verification steps to catch scale, collision, and material issues in Unreal.
Prepare Blender assets for import into Unity by checking scale, axes, materials, rigs, LODs, and collision meshes. Choose GLB or FBX for the asset type, export with clear transforms, and verify the imported result in Unity.
Build and validate level-of-detail (LOD) versions of game meshes in Blender. The workflow covers reduction targets, naming, screen-size transitions, and checks for silhouette, UVs, normals, and materials before export to a game engine.
Prepare Blender meshes and animations for Godot, usually as GLB or GLTF files. The skill covers export settings, scale, Godot-compatible materials, animation clips, and clearly named collision meshes, with a checklist for checking the imported asset in Godot.
Translate requests for “Search CLI” or `search_cli` into commands for the underlying `vs` executable. The skill checks the CLI version first and requires a product command reference before running mapped commands, helping avoid using an outdated or incorrect command surface.
Diagnose Roblox performance problems by measuring client and server costs, finding the code or assets behind them, and checking focused changes against device budgets. Prepare an update with a restart plan and rollback path for an owner to publish.
Write, review, and debug Roblox Luau with attention to task scheduling, deferred events, strict typing, cleanup, and parallel execution. Audit code, probe behavior in playtests, and keep performance changes only when benchmarks show a measurable gain.
Build and light Roblox environments, from graybox layouts and terrain to materials, collision, and atmosphere. Check how maps look and behave from the player’s view, and diagnose issues such as blocked doors, grass through floors, or unreadable lighting.
Structure Roblox game code by choosing script locations, separating server and client responsibilities, and organizing modules, services, signals, and tagged behavior. It also helps diagnose duplicate execution, require cycles, respawn problems, and leaked connections.
Build and fix Roblox game interfaces such as HUDs, menus, shops, and settings. Adapt layouts and controls for phones, tablets, computers, and consoles, then check usability, accessibility, and localized text with Studio's device simulator.
Build and audit Roblox player data systems for saving, purchases, trading, and migrations. Check session locks, retries, budgets, and crash recovery with simulated stores and servers, then identify what still requires testing in a published experience.
