Interactive guide for creating, reviewing, and improving agent skills (SKILL.md folders). Use when the user wants to build a new skill ('create a skill', 'make a skill for X', 'write a SKILL.md', 'turn this workflow into a skill'), review or improve an existing skill, fix a skill that never triggers or triggers too often, or validate a skill folder before sharing it. Do NOT use for general prompt writing, MCP server development, or editing arbitrary markdown files.

Reference and workflow guidance for the Grok Build CLI (`grok`), including interactive and headless runs, authentication, sessions, worktrees, permissions, sandboxing, MCP servers, plugins, inspection, updates, and automation output. Invoke only when the user explicitly requests the `grok-build` skill, explicitly asks to use Grok Build CLI, or an already-selected workflow requires Grok Build; do not invoke for general coding, generic shell tasks, or other agent CLIs.

Implement single-slide PowerPoint pages with PptxGenJS. Use when writing or fixing slide JS files: dimensions, positioning, text/image/chart APIs, styling rules, and export expectations for native .pptx output.

Manages Claude Code skills from plugin marketplaces using the local-skills CLI. Use when the user wants to add, update, remove, list, or inspect skills from a marketplace, or when managing the project's .claude/skills/ directory with version-tracked skills. Triggers on "install a skill", "add skill from marketplace", "update skills", "list available skills", "remove skill", or "local-skills".

Integrates the MSN JavaScript SDK (`window.$msstart`) into JavaScript games running on Microsoft Start. Handles SDK initialization, player authentication, cloud save key/value storage, display banner and interstitial/rewarded ad lifecycles, native sharing, leaderboard score submission, and in-app purchases. Use when the user mentions MSN SDK setup, MSN ads integration, game monetization with MSN, adding MSN features to a JavaScript game, `$msstart`, `msstart` script, MSN cloud save, or MSN IAP.

Integrates the GameDistribution JavaScript SDK (GD SDK) into a JavaScript or HTML5 game, covering SDK initialization, interstitial and rewarded ad display, banner ads, ad callback handling, and game lifecycle events. Use when the user asks about GameDistribution, GD SDK, game ads, HTML5 game monetization, ad integration, or wiring up ads and lifecycle events in a JavaScript or HTML5 game.

Look up Devvit documentation from the reddit/devvit-docs repository. Use when the user asks about Devvit APIs, patterns, configuration, or examples (trigger phrases: "how do I", "devvit docs", "show me the docs", "API reference").

Walk the user through setting up anything step by step. Use when the user asks for help setting up, configuring, installing, or getting something working — "help me set up X", "walk me through this", "setup-help". Differentiator: gives one current step at a time, then always lists every remaining setup step after each response.

Provision a hardened SELECT-only Postgres role so AI agents can safely read a production database. Works on Supabase and any Postgres. Use when the user wants agents to query prod data, says "read-only role", "safe prod DB access for agents", or is tired of running SQL by hand for agents. Differentiator: this skill CREATES the role and wiring; day-to-day querying belongs in a project-local skill.

MUST be read ANY time you interact with cmux in ANY way — listing/inspecting/creating/closing cmux workspaces, panes, or surfaces; reading or capturing pane/screen output; sending input or keys to a pane/surface; delegating to, polling, or checking on other agents running in cmux panes/surfaces; building or rearranging terminal layout; cmux browser automation; sending notifications/flashes/status/progress to the sidebar; editing cmux settings; or integrating an agent with cmux hooks. If your command starts with `cmux ` or touches a cmux workspace/pane/surface/agent, read this FIRST. Triggers on "cmux", "in this workspace", "this pane", "the other agent", "delegate to", "check on the agent", "send to the pane". macOS only (14.0+).

Update Spatie package documentation on spatie.be by re-importing docs for a given repo. Use after merging a PR that touches docs/, or when the user says 'update docs for [package]', 'rebuild docs for [repo]', 'import docs for [repo]', or invokes /update-spatie-docs [repo-name]. Takes a repo name argument (e.g., 'backup', 'laravel-medialibrary', 'laravel-pdf').

Defining and extracting kernel constants for syzkaller syzlang descriptions

Analyze codebases to identify reusable code patterns, duplications, and implementation patterns for future development. Use when refactoring code, identifying technical debt, finding opportunities for abstraction, or documenting common patterns in a directory or module. Outputs pattern catalogs, refactoring suggestions, and reusable template code.

Summarizes B2B account health by analyzing usage patterns, engagement trends, risk signals, and expansion opportunities. Use for customer success reviews, renewal preparation, QBRs, or account prioritization.

Fix PHP coding style issues using PHPCS and PHPCBF. Use this skill whenever the user mentions PHPCS, code style, coding standard, cs:fix, cs:check, PHP formatting, or asks to fix/check PHP code style. Also activate when you notice PHP files have been modified and need style compliance, or when a CI PHPCS check has failed.

Detects logical and semantic bugs by understanding program intent — catches issues that syntax-only tools miss. Use when static analysis has already run and found nothing, when the user reports incorrect behavior but no crash, or when reviewing algorithmic code for correctness.

Triage the last N production call logs for a Cekura agent against a set of KPIs / issues / goals, report the call IDs that hit each failure WITH the percentage of overall call logs affected, and distribute the remaining calls into a mutually-exclusive outcome taxonomy (e.g. not-answered / vetted / non-vetted caller-side / non-vetted agent-issue) with per-bucket percentages. Use when the user says "flag call log failures", "analyze the last N calls for issues", "what % of calls have <problem>", "which calls broke and how often", "find failing calls", "give me the breakdown of call outcomes", "what % of answered calls can be improved", or pastes an agent / project ID and lists the problems or KPIs to measure. Applies attribution rules so caller-side endings and recovered calls are NOT counted as agent failures. This is the upstream triage step that feeds `cekura-generate-scenarios` — it does NOT create scenarios.

Designs spatial UI layouts, prototypes hand gesture interactions, creates 3D menu systems, and plans gaze-based navigation for AR/VR/XR applications. Provides ergonomic placement guidelines, comfort zone thresholds, input latency budgets, and accessibility fallback patterns for immersive interfaces across platforms including Meta Quest, Apple Vision Pro, and WebXR. Use when the user asks about spatial computing interfaces, VR/AR UI design, mixed reality interactions, hand tracking UX, HUD design, holographic displays, headset UI, immersive environment layouts, 3D interface design, cockpit dashboards, or comfort-zone-compliant panel placement.

Builds native visionOS and Apple Vision Pro apps using SwiftUI, RealityKit, and the Liquid Glass design system. Creates volumetric views, implements Liquid Glass materials, configures immersive spaces, manages spatial WindowGroups, designs 3D UI layouts, and wires up RealityKit entities with gestures and attachments. Use when building visionOS apps, Apple Vision Pro experiences, volumetric windows, immersive spaces, mixed reality interfaces, or applying Liquid Glass effects with SwiftUI and RealityKit on visionOS 26.
