Quotes, 1-minute and 5-minute intraday OHLC, daily OHLC, bulk financials (income/balance/cash flow), earnings, analyst recommendations and opinions, company descriptions, peers, news, global indices (Dow/S&P/NASDAQ/VIX/DAX), and sector heatmaps. Covers US markets (NASDAQ/NYSE) and Argentine markets (BCBA). ⚠️ Unofficial API—read LIMITATIONS_TROUBLESHOOTING.md before production use.
Retrieve historical financial ratings and key metric scores over time using Octagon MCP. Use when analyzing overall ratings, return on assets, return on equity, discounted cash flow scores, debt-to-equity scores, and letter grades (A+, A, B, etc.) for any public company.
Manage Home Assistant configuration safely and fast — edit and deploy YAML (automations, blueprints, scripts, scenes, templates, MQTT), validate with ha core check, deploy via git or rapid scp, reload-vs-restart correctly, verify changes from logs, traces and entity state, and build Lovelace dashboards. Use for any Home Assistant config, automation, template, or dashboard work over SSH/hass-cli/MCP.
Create branching, draggable HTML mind maps and concept maps for capturing brainstorms, mapping knowledge structures, exploring debugging hypotheses, or organizing nested ideas. Always include a Submit button (calls `submitToClaude`) to send the captured structure back to the agent for next steps. Use whenever the user wants to capture, organize, or explore branching ideas, hypotheses, knowledge structures, or any tree- or graph-shaped thinking—especially when they say “brainstorm”, “map out”, “explore”, or “what if”.
Guides end-to-end Meta VR and Horizon OS app submission to the Meta Horizon Store — build validation, store-readiness checks, asset preparation, upload, and submission tracking. Use when preparing a Meta VR app for store publishing. Build paths: all Meta VR app stacks; use hz-quest-verify-first if the build path is unclear.
Discover, analyze, and prioritize keywords for SEO and GEO content strategies from a seed keyword or niche. Identifies high-value opportunities based on search volume, competition, intent, and business relevance. Generates topic clusters. For building a dated editorial calendar from your own Search Console data, use `content-planner` instead — this skill is seed-driven keyword discovery, not calendar scheduling. Use when asked to "find keywords", "keyword research", "keyword analysis", "search volume", "keyword difficulty", "content ideas from a seed", or any keyword discovery task.
Generates Kubernetes manifests including Deployments, Services, ConfigMaps, Secrets, Ingress, and HPA with best practices. Use when users request "Kubernetes setup", "K8s manifests", "deploy to Kubernetes", "container orchestration", or "K8s configuration".
Drawing elevation in MapLibre GL JS once a raster-dem source works — hillshade and `hillshade-method`, the `color-relief` layer and the `["elevation"]` expression, runtime contours with `maplibre-contour`, and 3D terrain with its camera and sky. Use when relief looks harsh, flat, or absent, or when the layer type or property for an elevation effect is unclear.
Verify and install all prerequisites for Omni Gateway custom policy development with PDK — Anypoint CLI v4 with the PDK plugin, Rust toolchain, wasm32-wasip1 target, Docker, and Anypoint Platform credentials. Use when any PDK skill reports a missing tool, when the user asks "how do I set up PDK", "what do I need for custom policies", "PDK prerequisites", or when a build/publish/test command fails with a toolchain error.
Write and run unit tests for custom Omni Gateway policies built with the Policy Development Kit (PDK) — wire up `src/tests/`, build a first `UnitTestBuilder` test, mock HTTP/gRPC upstreams with closures or `TraceBackend`, factor reusable `TestConfig` helpers, assert on responses / headers / violations, run with `make test` or `cargo test`, troubleshoot init-sleep races, authority mismatches, and feature-gate skew. Use whenever the user mentions "PDK unit test", "pdk-unit", "UnitTestBuilder", "test my policy", "cargo test PDK", "mock backend PDK", "Omni Gateway policy unit testing", `with_http_upstream_from_authority`, `with_entrypoint`, `TraceBackend`, or asks "how do I test an Omni Gateway policy", "how do I mock an upstream in pdk-unit", "why is my policy timer not firing in tests". For full `pdk-unit` API reference see `pdk-templates/templates/unit_testing.md`. For scaffolding / build / publish see `develop-pdk-policy`.
Add Polar billing to a TypeScript/JavaScript app using the @polar-sh/sdk package.

Build Retrieval-Augmented Generation (RAG) applications that combine LLM capabilities with external knowledge sources. Covers vector databases, embeddings, retrieval strategies, and response generation. Use when building document Q&A systems, knowledge base applications, enterprise search, or combining LLMs with custom data.
Use the Scrapfly CLI (`scrapfly`) to scrape web pages, capture screenshots, extract structured data with AI, crawl entire sites, and drive a cloud browser over CDP from a shell. JSON envelope on stdout for every command. Use when the user asks to "scrape a URL", "screenshot a page", "extract data from HTML", "crawl a site", "drive a browser with Playwright/CDP", "bypass anti-bot", or any task involving the `scrapfly` command.

Sweep the current conversation for durable knowledge - user preferences, project facts, operational gotchas, standing decisions, and unfinished next steps - and file each through explicit instructions, existing local conventions, or the private `.stow-notes.md` fallback, curating tiered, decaying destination files as it writes. Use when the user invokes /stow, asks to save or write down what was learned this session, or before a context reset or long break.
Teaches AI to design landing pages that feel like $150k agency work. Defines exact fonts, spacing, shadows, card structures, animations, and Korean typography standards that make Supanova-generated pages feel expensive and intentional. Blocks all common defaults that make AI designs look cheap or generic.
Set up Symphony (OpenAI's Codex orchestrator) for a user's repo. Use when the user mentions Symphony setup, configuring Symphony, getting Symphony running, or wants to connect their repo to Linear for autonomous Codex agents. Also use when the user says "set up symphony", "configure symphony for my repo", or references WORKFLOW.md configuration.
This skill should be used when the user wants to implement features or fix bugs using test-driven development. Enforces the RED-GREEN-REFACTOR cycle with vertical slicing, context isolation between test writing and implementation, human checkpoints, and auto-test feedback loops. Uses multi-agent orchestration with the Task tool for architecturally enforced context isolation. Supports Jest, Vitest, pytest, Go test, cargo test, PHPUnit, and RSpec.
Design a structured onboarding experience that gets new team members productive in 30, 60, and 90 days. Use when a new hire is joining, when contractors or agency partners need to ramp up, when an existing team is restructuring and members are switching focus, or when current onboarding feels chaotic and slow. Also triggers when one person owns all the tribal knowledge and you need to capture it, when you keep losing people in their first 90 days, or when a new project has many fresh members joining at once. Useful for engineering, design, product, marketing, and operations roles.

For the everyday chat.agent({...}) definition and the useTriggerChatTransport happy path, use the trigger-authoring-chat-agent skill instead.
Build or repair a typography system: a modular type scale, font choices and loading, hierarchy, line-height/line-length, and fluid sizing—delivered as tokens (Tailwind fontSize config or CSS variables) applied to real components. Use when the user says “the text looks off”, “fonts are inconsistent”, “headings don't stand out”, “pick fonts for me”, “it's hard to read”, “too many font sizes”, or when an audit finds font-size sprawl. Chooses the scale ratio based on product density (dense app vs. marketing vs. editorial), verifies contrast and measure, and produces type tokens plus a migration map from existing rogue sizes.
Create, update, list, and delete Webflow IX3 interactions (GSAP animations) through Webflow MCP. Use when the user wants click/hover/load/scroll/mouse-move animations, interaction timelines, or data_interactions_tool / create_interaction payloads.

How to drive the audio plugins ACE Studio hosts—third-party VST3/AU instruments and effects, and Studio's own built-in effects—through Studio's built-in computer use for a plugin's own interface, alongside the parameter and state/preset tools. Load whenever the user wants to load, tweak, preset or otherwise control a plugin, asks for computer use on one, or a job needs a control that exists only inside a plugin's UI. Pair with `ace-studio-features` for choosing a sound source.
Use when building an agent system (orchestrator, pipeline) or metering LLM spend. Triggers: "agent system" / "агентная система", "LLM billing". Not for one LLM call or prompt wording (agent-harness), evals (agent-evals) or protocols (agent-interop). Opt out: "no agent layer" / «без агентного слоя».
Use this skill when auditing a codebase for AI agent readiness, or when guiding improvements to make a codebase work well with agentic coding tools. It applies when users ask to evaluate test coverage, file structure, type system usage, dev environment speed, or automated enforcement—the five pillars that determine how effectively coding agents can operate in a project. Triggers on “audit my codebase,” “make this agent-ready,” “improve for AI agents,” “agent-friendly,” or questions about why agents struggle with a codebase.
Test-driven development for behavior that a unit test cannot reach: write the expectation against the running app before writing the code. Declare the consequence first, watch it fail, implement, then watch it pass. Use when building a user-facing feature, when the user asks for TDD on UI or full-stack work, when a unit test cannot express the outcome that matters, or when you want a red-green loop that runs against the real app instead of mocks.
Alibaba Cloud OSS scheduled local-folder sync skill using aliyun CLI, including integrated ossutil commands for incremental upload. Use when the user wants to schedule recurring local-to-OSS uploads, validate OSS backup prerequisites, set up cron or Task Scheduler for OSS sync, or clearly separate what stays on aliyun CLI from what remains OS-local or manual. Conditional write operations: creates the target bucket (PutBucket) only when the user confirms the bucket does not exist yet; optionally deletes test objects (DeleteObject) only when the user explicitly requests cleanup after verification. Triggers: "OSS scheduled sync", "定时同步到OSS", "aliyun ossutil cp --max-age", "aliyun ossutil cp -u", "cron upload to OSS", "Task Scheduler OSS upload", "aliyun CLI OSS sync", "本地目录增量上传 OSS".
