Read-only subagent that audits a repo against the vendor-neutral /
hot-swap standard: AGENTS.md canonical with a CLAUDE.md symlink, scoped
guides symlinked from .claude/rules with index lines, thin wrappers, and
relative correctly-directed symlinks. Substance in guides/, thin Claude
wrapper in adapters/, catalogued in the subagents handbook.
Document the portability protocol (vendor-neutral knowledge, vendor-named
symlinks) and a Claude subagents reference handbook, and link the
portability protocol from the retrofit playbook.
