End-of-session handoff — write the document a successor Claude needs to resume exactly where this session left off, audit the session for its most surprising positive and negative events, and change the environment so the positive becomes repeatable and the negative becomes structurally unlikely. Use whenever the user invokes /handoff, says they're wrapping up, asks to "write up where we are", wants continuity into a next session, or when context is running out mid-task and work must continue in a fresh session.
Build music apps with the Audius REST API and JavaScript SDK. Use this skill whenever the user wants to build a music player, streaming app, or audio application using Audius. Trigger on mentions of Audius API, @audius/sdk, create-audius-app, audius.co, api.audius.co, Audius OAuth, track streaming, playlist fetching, user profiles, or music app development on Audius. Also use when the user asks about uploading tracks, searching music, fetching trending tracks, or any REST API integration with the Audius platform.
Develop and extend the Audius Code Mode MCP server — the Effect-TS server that exposes the Audius and Open Audio Protocol APIs to LLMs via search + execute tools. Use this skill whenever the user wants to add features, fix bugs, refactor, or extend this MCP server. Trigger on mentions of MCP server development, adding new tools, modifying the sandbox, changing the transport layer, updating the spec loader, extending the search index, or any work on the audius-mcp-atris codebase itself. Also use when the user asks about the server architecture, how the components connect, or wants to understand the Effect-TS service/layer patterns used here.
Test all tools and endpoints of the Audius MCP server in parallel using subagents. Use this skill when the user asks to test the server, run a smoke test, verify the tools work, check if the API is responding, or validate the MCP server end-to-end. Also trigger when the user says 'run tests', 'test everything', 'smoke test', 'health check', or 'verify the server'. This runs read-only tests only — no writes, no mutations, no side effects.
Guide for designing, implementing, and advising on MCP servers that use Code Mode — the pattern where an LLM writes and executes code to orchestrate API calls instead of calling individual tools one at a time. Use this skill whenever the user mentions Code Mode, MCP tool proliferation, context window bloat from MCP tools, programmatic tool calling, LLM code execution in MCP, building a Code Mode server, or wants to compress a large API into a small MCP surface. Also use when the user asks how to reduce token cost of MCP tools, how to expose an entire API over MCP efficiently, or how to implement search+execute patterns in FastMCP, Cloudflare Workers, or custom servers.
Guide for creating high-quality MCP (Model Context Protocol) servers that enable LLMs to interact with external services through well-designed tools. Use when building MCP servers to integrate external APIs or services, whether in Python (FastMCP) or Node/TypeScript (MCP SDK).
Build on the Open Audio Protocol — the decentralized global music database. Use this skill whenever the user mentions Open Audio Protocol, OAP, go-openaudio, running validator nodes, protocol-level music infrastructure, decentralized music storage, DDEX wire protocol, $AUDIO staking, artist coins, mediorum, or self-hosted music indexing. Also use when the user wants to run a devnet, build directly against the protocol without Audius APIs, or integrate with OAP consensus/storage layers.
Create new skills, modify and improve existing skills, and measure skill performance. Use when users want to create a skill from scratch, edit, or optimize an existing skill, run evals to test a skill, benchmark skill performance with variance analysis, or optimize a skill's description for better triggering accuracy.
