Design and implement Agent Skills following best practices for VS Code and any Agent Skills-compatible agent. Use this skill when the user wants to create a new skill, improve an existing skill, review a skill for quality, or learn skill authoring best practices. Covers scoping decisions, instruction patterns, progressive disclosure, description optimization, and evaluation workflows.

Design and write VS Code custom agent files (.agent.md) following the minimum-sufficient-context spec: scoped tools, structured instructions, hard-enforcement hooks, and handoffs. Use this skill when creating a new custom agent, reviewing an existing .agent.md for quality, deciding an agent's tool set, writing agent body instructions, adding PreToolUse or PostToolUse hooks to an agent, designing an orchestrator-with-subagents team, or adapting the reference spec to a specific project. Covers frontmatter fields, body section ordering, hook input/output contracts, model fallback chains, and the orchestrator/subagent/handoff patterns.
