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.
