What problem does it solve? Adding a new CLI subcommand over an existing hosted domain operation is error-prone: developers guess payload fields, bypass the agent gateway, or forget write guards. This Skill provides a thin authoring playbook that keeps every new sugar command wired to the canonical agent schema discovery contract. ## Core Features & Use Cases - Authoring Patterns for Both CLIs: Step-by-step patterns for commander-based aops-cli commands and the manual argv plus topic registry approach in eops-cli. - Pre-Authoring Discovery Workflow: Commands to confirm operation registration, pull live input contracts via agent schema --tool, and search architecture guides before writing code. - Guard and Safety Conventions: Enforces --apply/--confirm guards for hosted writes, idempotency keys, and mandatory schema-discovery pointers in help text. - Use Case: You need to add aops-cli docman publish over an existing hosted operation. Follow the playbook to confirm the operation exists, fetch its input schema, implement the subcommand with shared helpers, and verify with --help and a preview invoke. ## Quick Start Ask the agent to author a new aops-cli sugar subcommand for a specific hosted domain operation, following the aops-cli-sugar-authoring skill and verifying it with agent schema discovery.
