Measured tools (12)

• get_template read-only

  Generate a rotated pillar, arch, staircase, room-5x5 or letter-w at a minimum corner. Returns a deduplicated protected batch body; no world read, reservation or mutation. Preview then explicitly build.

  Parameters:

  • id (required) — string
  • x (required) — integer
  • y (required) — integer
  • z (required) — integer
  • type — string
  • builder — string
  • rotation — integer — Rotate around y: 90 maps local +x to +z; then anchor the minimum corner at x,y,z.

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world not declared

• get_build_receipt read-only

  Authoritative historical batch outcome or unknown (absent or expired). No current occupancy guarantee. Public by ID, retained 24 hours.

  Parameters:

  • request_id (required) — string — Caller-generated canonical lowercase UUIDv4. Retained for 24 hours; unknown/expired is not proof of non-commit.

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world not declared

• get_world_stats

  Total cubes, per-block counts, active builders, world bounds, and current limits.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• get_overview

  Occupied cells from the coarse top-surface raster as [index,type,height], plus a small ASCII preview.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• get_region

  Page through exact cubes in x/z/y order. Pass next_cursor as cursor with the same box until null; concurrent edits require a fresh traversal for reconciliation.

  Parameters:

  • x (required) — integer
  • z (required) — integer
  • w (required) — integer
  • d (required) — integer
  • h — integer
  • y — integer
  • limit — integer
  • cursor — string

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• get_cube

  Return the cube at a coordinate, or null if that cell is empty.

  Parameters:

  • x (required) — integer
  • y (required) — integer
  • z (required) — integer

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• place_cube

  Place or replace a single cube. Coordinates are integers in [0,1000); y=0 is ground.

  Parameters:

  • x (required) — integer
  • y (required) — integer
  • z (required) — integer
  • type (required) — string
  • builder — string

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• remove_cube

  Clear the cube at a coordinate.

  Parameters:

  • x (required) — integer
  • y (required) — integer
  • z (required) — integer

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• build

  Apply 1 to 512 place/remove ops in one call. Ops run in order; results come back per op. Optional request_id safely replays the original result for 24 hours; changed operations conflict.

  Parameters:

  • ops (required) — array
  • builder — string
  • request_id — string — Caller-generated canonical lowercase UUIDv4. Retained for 24 hours; unknown/expired is not proof of non-commit.
  • protect_existing — boolean — Atomically reject accepted edits to cells occupied before the batch; preview is only a KV estimate.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• preview_build read-only

  Simulate the identical build payload without any persistent writes. Returns validation, replacements, affected bounds and before/after cells. Not a reservation.

  Parameters:

  • ops (required) — array
  • builder — string
  • request_id — string — Caller-generated canonical lowercase UUIDv4. Retained for 24 hours; unknown/expired is not proof of non-commit.
  • protect_existing — boolean — Atomically reject accepted edits to cells occupied before the batch; preview is only a KV estimate.

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world not declared

• fill_box

  Fill every cell of a box with one block type. Up to 4096 cells.

  Parameters:

  • from (required) — object
  • to (required) — object
  • type (required) — string
  • builder — string

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• clear_mine

  Remove every cube that carries the given builder handle. Bounded per call.

  Parameters:

  • builder (required) — string

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared
