This is an example configuration for a personal agent named 'bedtime' that can be added to the ~/.claude/agents directory. It includes a name, description, examples of usage, available tools, model, and color.

```yaml
---
name: bedtime
description: Use this agent when you want to quickly review Linear issues before bed to find simple, actionable coding tasks that can be worked on overnight. This agent helps you identify issues that are straightforward enough to tackle without major architectural decisions or product discussions, perfect for a 10-minute pre-sleep workflow to replace social media scrolling.\n\nExamples:\n- <example>\n  Context: User wants to find a simple issue to work on before going to sleep.\n  user: "I'm heading to bed, let me find something to work on"\n  assistant: "I'll use the bedtime agent to search through Linear issues and find you something suitable to work on tonight."
  <commentary>\n  The user is preparing for their bedtime routine and wants to find a simple coding task, so we use the bedtime agent to search Linear and present suitable options.
  </commentary>
</example>\n- <example>\n  Context: User explicitly calls the bedtime agent.\n  user: "/bedtime"\n  assistant: "Let me launch the bedtime agent to find you a good issue for tonight's coding session."
  <commentary>\n  The user has directly invoked the bedtime command, so we use the bedtime agent to search for appropriate issues.
  </commentary>
</example>
tools: Glob, Grep, LS, Read, Edit, MultiEdit, Write, WebFetch, TodoWrite, WebSearch, BashOutput, KillBash, mcp__linear-server__list_comments, mcp__linear-server__create_comment, mcp__linear-server__get_document, mcp__linear-server__list_documents, mcp__linear-server__get_issue, mcp__linear-server__list_issues, mcp__linear-server__create_issue, mcp__linear-server__update_issue, mcp__linear-server__list_issue_statuses, mcp__linear-server__get_issue_status, mcp__linear-server__list_my_issues, mcp__linear-server__list_issue_labels, mcp__linear-server__create_issue_label, mcp__linear-server__list_projects, mcp__linear-server__get_project, mcp__linear-server__create_project, mcp__linear-server__update_project, mcp__linear-server__list_project_labels, mcp__linear-server__list_teams, mcp__linear-server__get_team, mcp__linear-server__list_users, mcp__linear-server__get_user, mcp__linear-server__search_documentation, Bash
