Create an ability

POST: optional client-minted id (any RFC 4122 UUID; the server mints a UUIDv7 otherwise). PUT/PATCH: ignored, the path id wins.

Name of the element. null stores ''.

Any kind of details about the element. null stores ''.

The top level category to which the element belongs. null stores ''.

The sub level category through which the element is further classified. null stores ''.

URL to an image representing the element. null stores ''.

Describes specific difficulties or constraints that make the ability hard to master or use effectively. null stores ''.

How widely the ability is known or practiced, and potential clues to its origins and cultural diffusion. null stores ''.

Length of time the ability remains active or its effects persist, measured in TIME units.

Relative measure of the ability's inherent potency or force, used for scaling or comparison purposes.

Effective reach or distance at which the ability can be used, in the world's distance unit (World distance_unit).

A construct that expresses the conceptual, social, or institutional system this ability operates within. Links a Construct: an existing one in this world.

The phenomenon that serves as the enabling force or condition that allows this ability to function. Links a Phenomenon: an existing one in this world.

Location where the ability is most strongly rooted, developed, or traditionally practiced. Links a Location: an existing one in this world.

Name of the element.

Any kind of details about the element.

The top level category to which the element belongs.

The sub level category through which the element is further classified.

URL to an image representing the element.

Method or conditions under which the ability is activated.

Describes specific difficulties or constraints that make the ability hard to master or use effectively.

How widely the ability is known or practiced, and potential clues to its origins and cultural diffusion.

Length of time the ability remains active or its effects persist, measured in TIME units.

Effective reach or distance at which the ability can be used, in the world's distance unit (World distance_unit).

A construct that expresses the conceptual, social, or institutional system this ability operates within. A Construct's id.

The phenomenon that serves as the enabling force or condition that allows this ability to function. A Phenomenon's id.

Location where the ability is most strongly rooted, developed, or traditionally practiced. A Location's id.

The world change sequence at this element's last write.

The world membership that created this element, or null when the world's owner did.

The world membership that last changed this element, or null when the world's owner (or the server) did, or no write has touched it since doors were recorded.

The door of the last change: seat (an agent seat), mcp (the MCP server), declared (the request sent an X-OW-Agent header), api, v1, sync (the mobile app's sync) or server (the server, on its own behalf). The first three mean an agent made it. Null: no write since doors were recorded.

Present, and true, only on an element this reader knows of but does not see whole: a guest or player reaches it only because its own Character's sheet links to it (one step out). Such a row keeps id, type, name, description, supertype, subtype, image_url, created_at, updated_at and change_seq; every other field reads as unset (text "", numbers and single links null, multi links [], created_by, changed_by and changed_via null, no extension fields), its files are 404, and search matches only its name and description. Absent: the element is whole. Any other grant (it names the reader's Character, the reader knows it, it is on the roster, the reader made it) makes it whole; a hidden element is never even a stub.
