Constraint: Public README content should guide external AI users, not document internal maintenance, publishing, sync, or validation workflows.
Rejected: Keeping repository maintenance and sync instructions in public README | those belong in the internal adapter skill.
Confidence: high
Scope-risk: narrow
Directive: Keep public marketplace docs limited to install, update, uninstall, and public plugin capability guidance.
Tested: python scripts/validate_marketplace.py; README scan for internal workflow terms.
