Markus's agent-building skill teaches an agent to create Markus agent packages: the folder layout, the agent.json manifest, the ROLE, HEARTBEAT and POLICIES files, and avatar and screenshot images. Packages must be saved under ~/.markus/builder-artifacts/agents/ for the Markus Builder and Hub to find them, so it is only useful if you use Markus.

Lead an email team in Spark: workload, assignments and triageReaddle's team-lead persona skill sets an agent up to manage a team's email through the Spark command-line tool. It reviews who holds how many open items, assigns unassigned messages with a comment and an optional due date, triages shared inboxes and prepares material for standups. It builds on Spark's base skill for commands and filters. It needs Spark with team features and triage access.Digital workersEmail
Build agents with the Mastra frameworkThis skill guides building with Mastra, a TypeScript framework for building agents and workflows with tools, memory, and storage. It tells the agent to check current docs and APIs rather than rely on memory, and it helps with setup, frequent errors, version migrations, and the mastra api CLI.AI agent frameworkAgentsTypeScript
Write the instructions for a customer-support agentMastra's customer-support-agent playbook helps you write the setup for an agent that triages and answers support tickets, email, chat, refund requests and product issues. It gives naming and description patterns, a system prompt template, and rules for when the agent may only draft and when it may send or act. Account access, payments, legal threats, privacy requests and large refunds go to a person unless your tools and policy allow otherwise. The file sits in Mastra's enterprise folder, so it is source-available under the Mastra Enterprise Edition License, not open source, and production use needs an agreement with Mastra.Customer supportsupportagents
Evaluate an ADK agent with agents-cliThis skill runs and reads evaluations for Google ADK (Agent Development Kit) agents, through the agents-cli eval commands. It walks a loop of preparing a dataset, running the eval, studying failures, and fixing the agent, then repeating. It also helps pick metrics, including LLM-as-judge scoring, and lists usual reasons a score drops.AI agent frameworkAgentsEvaluation
