# `schema_store`

Save, load, list or delete named composition schemas.

Generated from @oods/foundry 0.10.1

One of the 20 tools your assistant sees by default.

Use it when retaining a UiSchema across sessions or past its 30-minute reference expiry; use schema_render to validate/render it or object_registry to manage object definitions. Returns the selected stored schema, listing or write result. action selects the operation; save/load/delete use name. Every save overwrites that name and increments its version; only the latest is loadable. apply is accepted but ignored: save and delete always write. Full tool JSON schemas are separate MCP resources, not entries in this store. Reference: TOOL-REFERENCE.md#schema_store; full schema: oods\://schemas/schema_store.input.json.
