agent-creator
Create production-grade agent .md files aligned with the current Anthropic subagent contract. Also validates existing agents against the marketplace compliance rules. Use when building custom subagents, reviewing agent quality, or creating parallel agent architectures for orchestrator skills. Trigger with "/agent-creator", "create an agent", "build a subagent", or "validate my agent". Make sure to use this skill whenever creating agents/*.md files for plugins or standalone use.

# Agent Creator
Creates spec-compliant agent .md files following Anthropic's current documented subagent
frontmatter contract. Supports both creation of new agents and validation of existing ones.
## Overview
Agent Creator fills the gap between ad-hoc agent files and production-grade agents that pass
marketplace validation. It distinguishes the 16 fields in Anthropic's public frontmatter table
from runtime-recognized experimental options, then layers the stricter Intent Solutions required
set on top. It prevents
common mistakes (using `allowed-tools` instead of `disallowedTools`, adding invalid fields like
`capabilities` or `expertise_level`), and produces agents with substantive body content that
actually guides Claude's behavior.
