Use when a rendered visual would help — verifying a change renders, checking code output by eye instead of a test run, capturing a bug repro or a visual for a PR. Drives a real running web app in headless Chromium via a reusable Playwright runner and writes a PNG.

Build MCP servers in Python with FastMCP. Define tools / resources / prompts, build the server, test locally, deploy to FastMCP Cloud or Docker. Use whenever the user mentions building an MCP server, exposing tools to LLMs, FastMCP, building a Claude integration, or troubleshooting FastMCP module-level server, storage, lifespan, middleware, OAuth, or deployment errors.

Set up the Google Workspace CLI (gws) from scratch. Guides through GCP project creation, OAuth credentials, authentication, and installing 90+ agent skills for Claude Code. Use whenever the user wants to set up gws for the first time, configure Google Workspace API access, install the Google Workspace CLI, or troubleshoot gws auth issues.

Receive and verify Ada (ada.cx) AI customer service webhooks, delivered through Svix. Use when setting up an Ada webhook endpoint, getting the per-endpoint whsec_ signing secret, debugging svix-id / svix-timestamp / svix-signature verification, or handling events like v1.conversation.created, v1.conversation.message, v1.conversation.ended, v1.conversation.handoff.ended, v1.end_user.created, v1.end_user.updated, v1.audit_log.emitted and v1.proactive_call.* voice outreach events.

Receive and verify Act-On outgoing webhooks (marketing automation, delivered through Svix). Use when setting up Act-On webhook handlers, debugging Svix signature verification (svix-id, svix-timestamp, svix-signature, whsec_ Signing Secret), telling events apart when the payload has no event type, or handling contact.added, contact.updated, contact-bounce.hard, form.submitted, contact-opt.global-opt-out, automated-program.started and subscription-category.opt-in events.

Databricks AI Search (formerly Vector Search) endpoints and indexes for RAG and semantic search. Use when asked to: create Standard or Storage-Optimized endpoints and Delta Sync or Direct Access indexes with AISearchClient; query with ANN, hybrid, or full-text search and filters; sync, monitor, or migrate indexes; set a target QPS, triage 429s, or load-test an endpoint; wire an index into an agent as a retriever tool. NOT for: no-code document Q&A (databricks-genie-agents); serving-endpoint CRUD (databricks-model-serving); custom ResponsesAgent authoring and deployment (databricks-ml-training).

Databricks AI Runtime, the `databricks air` CLI commands for submitting and managing GPU training workloads on Databricks serverless compute. Use for: writing and submitting `databricks air` workload YAML, passing hyperparameters and secrets, checking run status, listing/cancelling runs, streaming a run's logs and watching its progress, custom Docker image setup, and environment configuration.

Comprehensive guide to Spark Structured Streaming for production workloads. Use when building streaming pipelines, working with Kafka ingestion, implementing Real-Time Mode (RTM), configuring triggers (processingTime, availableNow), handling stateful operations with watermarks, optimizing checkpoints, performing stream-stream or stream-static joins, writing to multiple sinks, or tuning streaming cost and performance.

Discover, explore, and query Databricks data via Genie — the CLI equivalent of the Genie One MCP. MUST be invoked whenever the user asks to find or locate data ('what tables are in X', 'where does X live', 'which catalog/schema has Y'), answer a natural-language question about the data, or write a SQL query.

Security patterns for Falcon Foundry apps including OAuth scopes, RBAC, input validation, UI security, and credential management. TRIGGER when user asks to "configure OAuth scopes", "secure a Foundry app", "handle secrets", "add input validation", or needs to review a Foundry app for security concerns (XSS, CSP, credential management). Also trigger during pre-deployment security reviews.

TRIGGER when user asks for a "standalone Falcon Fusion workflow" that needs NO Foundry app — just a trigger plus actions that already exist in their CID, with no UI, function, collection, or custom API integration to build. DO NOT TRIGGER when the request needs anything built (a custom action, a UI page, a function, a collection) — that is a Foundry app and development-workflow owns it. This skill exists so the redirect works without hooks and yields to the real Falcon Fusion plugin when both are loaded.

Download YouTube videos with customizable quality and format options. Use this skill when the user asks to download, save, or grab YouTube videos. Supports various quality settings (best, 1080p, 720p, 480p, 360p), multiple formats (mp4, webm, mkv), and audio-only downloads as MP3.

Back-port a specific commit from master to a release branch via cherry-pick. Creates a dedicated backport branch, attempts the cherry-pick, pushes it, and opens a PR by default. Returns to the original branch when done (success or failure). If there are merge conflicts, diagnoses the root cause without attempting an autonomous resolution. Use when asked to "backport", "cherry-pick to release", or "port a fix to a release branch".

Enumerates every public component set in a CDS Figma file and produces a list of [Component Name]: [Figma URL] entries grouped by page section. Use this skill whenever asked to list, generate, or audit Figma component URLs, produce a component inventory from a Figma file, or when doing a Code Connect refresh/audit that requires knowing which Figma node each component maps to. Also trigger when someone asks "what are the Figma URLs for CDS components" or wants to find the node-id for a specific component.

Contribute a verified bug fix for LazyCodex, lazycodex-ai, omo-codex, bundled Codex skills, or upstream Codex CLI bugs. LazyCodex-owned defects get a fork PR against code-yeongyu/oh-my-openagent (base dev, source-tree paths under packages/omo-codex/plugin, with the changelog fragment); upstream Codex bugs get a fork PR against openai/codex. code-yeongyu/lazycodex is a generated distribution mirror and never gets a PR. Use when the user asks to fix a bug, contribute a bug fix, contribute to fix bug, open a PR for a bug, or debug and PR a LazyCodex/Codex defect.

Searches and rewrites code by AST shape across 25 languages. Use when the target is a syntax pattern (every call/class/import shaped like X, a codemod, a YAML rule) rather than literal text; for plain strings, comments, or filenames, use rg.

Terminal and TUI automation CLI for AI agents. Use when the user needs to create a terminal session, run a command in a terminal, automate an interactive CLI or TUI, wait for terminal output, capture a TUI screenshot, export a terminal recording, or test a CLI workflow with reviewable artifacts.

Use when writing, modifying, or debugging Playwright tests in the orchestration cluster webapp — integration tests, visual regression, or accessibility tests; MSW mocking, Page Object Models, or axe-core. Test directory: webapp/client/apps/orchestration-cluster-webapp/test/.
