Rust Agent Handoff Protocol

Subagents work in isolated context. This protocol enables communication through Markdown+frontmatter files and inline frontmatter passing.

File Location

.local/handoff/{id}.md    where id = {timestamp}-{agent}

Example: .local/handoff/2025-01-09T14-30-45-architect.md

Frontmatter Schema

All fields are flat scalars — no nested structures in frontmatter.
