Agents

Single-purpose persona definitions. Spawn in parallel when reviews are independent.

Agent	Purpose
design-critic	Senior-designer feedback on a proposal.
a11y-reviewer	Accessibility-only review (WCAG, keyboard, focus, contrast).
token-extractor	Pull tokens from a new refs/ source into knowledge/design-tokens/.
component-architect	Design API + anatomy for a new component.

Each agent's body contains a self-contained brief. The harness can spawn it with that file as the system-prompt overlay.

Claude Code reads the YAML frontmatter (name, description, tools). Codex CLI / generic agents read the body text and apply it as a role.
