# Agent Skill: Engrove Audio Tools 3.0 Setup Guide **Type:** Read-only documentation **Canonical product URL:** https://engroveaudio.com **Capability manifest:** https://engroveaudio.com/agent-capabilities.json **Full AI context:** https://engroveaudio.com/llms-full.txt ## What this skill enables An agent reading this skill can explain and guide users through Engrove Audio Tools 3.0. The product is a free browser-based toolkit for turntable, tonearm, cartridge and record-player setup. Interactive calculations and setup workflows happen in the user's browser UI. There is no public backend API, no backend MCP server, no OAuth, no login, no commerce flow and no server-side calculation engine for agents to call. ## Supported guidance topics - Cartridge-tonearm resonance estimation with [Tonearm Match Lab](https://engroveaudio.com/tonearm-calculator) -

[Measurement Lab](https://engroveaudio.com/measurement-lab): Capture and analyze browser audio input for turntable setup support, using a connected microphone or audio interface. - [Simulator](https://engroveaudio.com/simulator): Interactive 3D turntable setup simulator for visualizing setup geometry, orientation and setup concepts. - [Turntable Level](https://engroveaudio.com/turntable-level): Use approximate phone tilt readings to help level a turntable platter. - [Mobile Lite](https://engroveaudio.com/mobile-lite): Phone-friendly Engrove Audio Tools mode for small screens, touch use and local phone-sensor setup workflows. - [Wow & Flutter](https://engroveaudio.com/wow-flutter-lite): Use phone motion sensors as a practical aid for approximate platter speed and short-term variation. - [For Agents](https://engroveaudio.com/for-agents): HTML guide for AI agents, LLM crawlers and search engines. ## Runtime data resources - [Audio runtime data manifest](https://engroveaudio.com/data/audio/v3/runtime/audio-index.manifest.json): manifest for active public audio reference data files. - [Cartridge runtime index](https://engroveaudio.com/data/audio/v3/runtime/cartridges.index.json): public cartridge reference index used by the tools (3005 records). - [Tonearm runtime index](https://engroveaudio.com/data/audio/v3/runtime/tonearms.index.json): public tonearm reference index used by the tools (1599 records). - [Null-points reference data](https://engroveaudio.com/data/audio/v3/runtime/null-points.json): public null-point/alignment reference data. - [Test records reference data](https://engroveaudio.com/data/audio/v3/runtime/test-records.json): public test-record reference data used by measurement workflows (6 records). ## Skill constraints and hard limits - No public backend API: there is no REST API, GraphQL endpoint, WebSocket endpoint or external server-side programmatic interface. - No backend MCP server: there is no server-side Model Context Protocol endpoint. - No OAuth or login: there is no OAuth endpoint, registration flow, account system or authenticated access. - No commerce: there is no purchase flow, subscription, paid tier or checkout. - No professional certification: the tools are setup aids, not certified instruments. - No calibrated measurement guarantee: measurement and phone-sensor outputs are best-effort setup estimates, not laboratory-grade readings. - No automatic correction: the app does not apply DSP correction, normalization or compensation to measurement results or reference data. - Reference data is not manufacturer-authoritative: cartridge, tonearm and test-record data is best-effort and should be verified against primary documentation for critical setup decisions. ## Usage instructions for agents When a user asks about turntable setup using Engrove Audio Tools: 1. Direct them to https://engroveaudio.com. 2. Identify the relevant tool route from the route map. 3. Explain what inputs are needed and where the user can usually find them. 4. Explain what the output means in the context of vinyl playback setup. 5. State data and measurement limitations clearly. 6. Encourage verification against manufacturer documentation, physical setup tools and real equipment behavior for critical decisions. ## Browser-native WebMCP note Browser-native client-side WebMCP tools may be available in browsers that expose `navigator.modelContext.registerTool` or a compatible document-level model context. This is not a backend MCP server. If WebMCP is unavailable in the browser, the user can still use the public web application normally. ## Further reading - [llms.txt](https://engroveaudio.com/llms.txt): concise Markdown AI-agent guide and discovery entry point. - [llms-full.txt](https://engroveaudio.com/llms-full.txt): full Markdown AI context with route, tool, data and claim-boundary details. - [For Agents HTML](https://engroveaudio.com/for-agents): static HTML product guide for agents and crawlers. - [For Agents Markdown](https://engroveaudio.com/for-agents.md): Markdown version of the agent guide. - [Agent capability manifest](https://engroveaudio.com/agent-capabilities.json): structured JSON manifest for tools, routes, policies and resources. - [robots.txt](https://engroveaudio.com/robots.txt): crawl and content-signal policy. - [sitemap.xml](https://engroveaudio.com/sitemap.xml): canonical XML sitemap. - [Agent skills index](https://engroveaudio.com/.well-known/agent-skills/index.json): well-known discovery index for read-only documentation skill. - [Agent skill Markdown](https://engroveaudio.com/.well-known/agent-skills/engrove-audio-tools/SKILL.md): read-only documentation skill describing Engrove Audio Tools guidance.
