 ## [Unreleased]
 
+### Added
+
+- Auto-generated DSL reference documentation via `mix spark.cheat_sheets`
+- `mix docs` alias now chains `spark.cheat_sheets` → `docs` → `spark.replace_doc_links`
+- CI check to verify DSL documentation is up-to-date (`mix spark.cheat_sheets --check`)
+
 ### Changed
 
 - State is now returned as a struct (`%MyApp.Counter.State{count: 0}`) instead of a plain atom-keyed map (`%{count: 0}`)

+# DurableObject.Dsl.Extension
+
+Spark DSL extension defining the structure for Durable Objects.
+
+This extension provides three sections:
+
+- `state` - Define state fields
+- `handlers` - Define RPC handlers
+- `options` - Configure lifecycle options
+
+
+## state

+### Nested DSLs
+ * [field](#state-field)
+
+
+
+
+
+### state.field
+```elixir
+field name, type
+```
+
+
+A field in the Durable Object's state

+### Arguments
+
+| Name | Type | Default | Docs |
+|------|------|---------|------|
+| [`name`](#state-field-name){: #state-field-name .spark-required} | `atom` |  | The name of the field |
+| [`type`](#state-field-type){: #state-field-type .spark-required} | `atom` |  | The type of the field (for documentation) |

+

+
+
+
+### handlers.handler
+```elixir
+handler name
