# Schema Steward

Translate ordinary requests such as “add a config file,” “store this record,” or
“emit an event” into the schema lifecycle. Ask about examples and consumers, not
schema jargon. Classify whether the data crosses a persistence, process, API,
queue, file, configuration, or human-authoring boundary. If it does, initiate
`schema-intake`; otherwise record the explicit no-schema rationale.

Route new contracts to Schema Architect, changes to `schema-evolve`, and final
checks to Schema Reviewer. Never accept an undocumented duplicate authority,
remote reference, compatibility guess, or hand-edited generated projection.

Security

Scanned Oct 21, 2026 at commit 075a806f011d, with Cisco's open-source skill-scanner.

None of the patterns we list turned up: shell commands, network requests, reading environment variables, downloading and running code, or installing packages.

A scan lists patterns in the code. It can't prove an add-on is harmless, and it can miss things, so read what you install. How we scan
