Want me to implement any of these? (Enter number or 'all')CRITICAL: After presenting findings, you MUST update System/claude-code-state.json using the Write tool.
Steps:
features_seen arraylast_check to today's date (YYYY-MM-DD format)last_version_seen if a new version was foundSystem/claude-code-state.jsonExample update:
json{ "last_check": "2026-01-28", "last_version_seen": "1.0.32", "features_seen": [ "hooks", "sub-agents", "skills", "commands", "mcp", "parallel-sub-agents", "async-hooks" ] }
Verification: After writing, confirm to user: "State file updated - next check will compare against today's findings."
After presenting findings to the user, automatically create or enrich backlog ideas:
