Schema index

JSON Schemas under Docs/Modding/schemas define document structure, required properties, field types, enumerations, and numeric limits. Runtime validation remains authoritative for rules that depend on other files, loaded Core templates, asset dimensions, or content IDs.

For a browsable table of every root property and reusable definition, use the generated field-by-field API reference.

Pack and distribution contracts

Schema	Used for
manifest.schema.json	Pack identity, version, dependencies, conflicts, content roots, previews, and generated bundle metadata
catalog-v1.schema.json	Community catalog listings and immutable releases; not a pack content document
asset-patch.schema.json	Explicit replacement of published asset slots

Content contracts

Schema	Content type	Guide
challenge.schema.json	challenge	Rules
clothing.schema.json	clothing	Clothing
difficulty.schema.json	difficulty	Rules
enemy.schema.json	enemy	Enemies
enemy-animation.schema.json	enemyAnimation	Enemies
player-animation.schema.json	playerAnimation	Enemies
player-attachment.schema.json	playerAttachment	Clothing
rule-profile.schema.json	ruleProfile	Rules
stage.schema.json	stage	Stages and maps
stage-script.schema.json	stageScript	Stage scripts
usable.schema.json	usable	Weapons and items
weapon.schema.json	weapon	Weapons and items

Tooling and map contracts

Schema	Used for
enemy-rig-reference.schema.json	Frozen Core-enemy rig reference exchanged with authoring tools
player-rig.schema.json	Normalized player rig data
tiled-map.schema.json	Supported Tiled JSON map subset
tiled-tileset.schema.json	External Tiled JSON/TSJ tilesets

Which source wins?

Use this order when sources seem to disagree:

1. Runtime parser and cross-file validation for what the current build accepts.
2. JSON Schema for structural validation and limits.
3. Public wiki for workflows and explanation.
4. Example packs for practical composition.
5. Internal planning documents for design history only.

Report any disagreement between the first three as a documentation or schema defect. Do not work around it by depending on an undocumented parser behavior.

Validation

From the repository root:

dotnet run --project Tools/ModSchemaValidator -- .

To validate one loose pack:

dotnet run --project Tools/ModSchemaValidator -- . Mods/example.my-mod

See Validation and errors for the difference between schema and runtime validation.
