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.

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.

Use when the user asks for parallel team-style execution of multiple features in one project — orchestrates a team lead + N dev workers, one feature per worktree, each gated on x-qa E2E tests, with blocker escalation to human via SendMessage. Hard requires `plugin.omc` (TeamCreate/SendMessage primitives) and `.x-skills/x-qa/profile.json` (E2E gate).

Download videos, audio, and transcripts from YouTube and 1000+ sites with yt-dlp. Use when the user mentions "yt-dlp", "youtube-dl", wants to download a video, rip audio from a video, or extract a transcript from a URL.

Make sure email actually reaches inboxes. Use this skill when setting up email authentication (SPF, DKIM, DMARC), diagnosing emails landing in spam, planning a domain reputation strategy, monitoring sender reputation, or hardening against email spoofing. Triggers on email deliverability, SPF, DKIM, DMARC, spam folder, sender reputation, mailbox provider, soft bounces, bounce rate, BIMI, MTA-STS, deliverability audit. Also triggers when a marketing or transactional email isn't reaching users.

Use when authoring, creating, refining, or troubleshooting agent skills — scaffold SKILL.md and frontmatter, write and optimize the trigger description, structure the body with progressive disclosure, validate structure, and test or debug activation. Also when building a new skill from scratch, when a skill won't trigger, loads incorrectly, or the agent ignores it entirely. Use when a skill misbehaved in the current session and needs adjustment based on learnings.

Retrieve the Markdown version of a public web page from a URL using the agent's built-in URL fetch capability and markdown.new. Use when a user asks for page content in Markdown, cleaner extracted page content for LLM use, or URL-to-Markdown conversion.

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.

Use when building HTTP servers with Bun.serve, handling requests/responses, implementing routing, creating REST APIs, or configuring fetch handlers.

100+ animated React components (Aceternity UI) for Next.js with Tailwind. Use for hero sections, parallax, 3D effects, or encountering animation, shadcn CLI integration errors.

Provides concrete guidance on building terminal emulators in Swift using SwiftTerm, including configuring terminal views, parsing ANSI/VT100 escape sequences, managing PTY connections, and optimizing text rendering performance. Use when the user is building a terminal app, console view, or xterm-compatible emulator in Swift, integrating SwiftTerm into a SwiftUI or UIKit/AppKit app, working with PTY or SSH stream bridging, handling keyboard input and escape sequences, or optimizing terminal rendering on macOS, iOS, or visionOS.

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.

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.

Reviews contracts for compliance issues, drafts and audits privacy policies, assesses GDPR/CCPA/HIPAA/SOX/PCI-DSS obligations, identifies regulatory requirements, and flags legal risks across multiple jurisdictions. Use when the user asks about legal compliance, regulatory requirements, GDPR, CCPA, privacy policies, terms of service, contract review, data protection, data handling, legal review, or industry-specific regulations such as HIPAA, SOX, or PCI-DSS.

Use when the user says "get started with Cekura", "set up Cekura", "onboard to Cekura", "I'm new to Cekura", "help me set up my agent", "how do I use Cekura", "walk me through Cekura", "configure my project", "first time using Cekura", or needs guidance on initial platform setup. Covers two onboarding paths: **testing** (default — build evaluators and run simulated calls) and **observability** (ingest production call logs and evaluate them).

Operate Ryvn infrastructure: manage organizations, provision environments, deploy services and installations, configure blueprints, manage release channels and promotion pipelines, set up connections and variable groups, view logs, approve tasks, and handle preview deployments. Use this skill whenever the user mentions Ryvn, environments, services, installations, blueprints, deployments, infrastructure, provisioning, Kubernetes, cloud, GCP, service installations, release channels, or promotion pipelines, even if they don't say "Ryvn" explicitly.

Query the OpenAI developer documentation via the OpenAI Docs MCP server using CLI (curl/jq). Use whenever a task involves the OpenAI API (Responses, Chat Completions, Realtime, etc.), OpenAI SDKs, ChatGPT Apps SDK, Codex, MCP integrations, endpoint schemas, parameters, limits, or migrations and you need up-to-date official guidance.
