The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
ggb_clear Clear the figure ~27
Remove every object to start a new figure (can be reverted with ggb_undo).
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
ggb_delete Delete objects ~53
Delete objects. WARNING: everything that depends on them is deleted too (see usedBy in ggb_get_state). To change an object, redefine it with ggb_run_commands instead.
| Name | Type | Req | Description |
|---|---|---|---|
| names | array | yes | – |
No output schema declared.
No examples provided.
ggb_evaluate Evaluate expressions ~92
Evaluate GeoGebra expressions against the current figure WITHOUT adding objects, to verify the construction. Examples: "Angle(B, A, C)", "Distance(B, M) == Distance(M, C)", "AreCollinear(A, H, O)", "AreParallel(Line(A, D), Line(B, C))", "Radius(omega)", "Area(poly1)".
| Name | Type | Req | Description |
|---|---|---|---|
| expressions | array | yes | – |
No output schema declared.

ggb_export Export the figure ~63
Save the figure to a local file: "ggb" (GeoGebra file, can be opened again in GeoGebra) or "png" (image).

|---|---|---|---|
| format | string | yes | – |
| path | string | yes | Destination file path on this computer |

| show_axes | boolean | – | – |
| show_grid | boolean | – | – |

ggb_get_state Read the figure ~93
List the objects currently in the figure: name, type, definition, value, point coordinates, visibility, dependsOn (parents) and usedBy (objects that would change or be deleted with it). Always call this before fixing a figure: the user may have edited it by hand.
| Name | Type | Req | Description |

Assigning to an existing name REDEFINES that object and its dependents update. Returns, per command: ok, created/removed objects, warnings (undefined objects, names not created) and, for failures, hints about the likely cause.
| Name | Type | Req | Description |
