Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| list_presetsA | List OrcaSlicer presets. preset_type is 'process', 'filament', or 'machine'. Returns the user's own presets by default. Pass |
| get_presetB | Read a preset: its inherits chain and the settings it overrides itself. Pass |
| set_preset_valuesA | Edit a preset FILE. Needs an OrcaSlicer restart to take effect — prefer suggest_settings when it is available. Values are strings, or lists of strings for per-extruder settings. System presets cannot be edited — clone first. |
| clone_presetC | Create a new user preset inheriting from an existing preset. |
| preflightA | Check the settings in force against known-bad combinations. No slice needed, and no judgement of yours involved — these are deterministic rules over the selected presets, including edits not yet saved. Run this before advising on a print, and before answering a general "what should I change" — a finding here is a fact about their setup, worth more than anything you would infer, and worth saying first. Each one carries the settings it came from, for describe_setting or a suggested change. Says nothing when nothing is wrong, which is the usual answer. It knows nothing about the model on the plate: overhangs, size and adhesion area are measure_slice's job, not this one's. |
| get_current_presetsA | The process, filament, and machine presets currently selected in OrcaSlicer. These are profiles, not the model: for what the user has clicked on and which plate they are looking at, call get_selection. |
| describe_settingA | What a setting does: its label, tooltip, units, default, and either its allowed values or its numeric range. Read this before setting anything whose legal values you are unsure of —
enum settings accept only the keys in |
| find_settingsA | Search settings by name, label, or description. Use this to find the setting for a problem when you do not already know its key. Matches a substring, so 'seam' or 'stringing' both work. Returns short excerpts; follow up with describe_setting on the one you want. |
| search_wikiA | Search the OrcaSlicer wiki: calibration procedures, troubleshooting, print preparation, and the pages behind the settings. Ask it the question — "how do I calibrate pressure advance" — rather than a
key. Two in five of these pages explain no setting at all, so this reaches
what find_settings cannot. Returns an excerpt per page; pass a |
| read_wikiA | The wiki on one topic. It is the authority on procedures and on recommended values — read it rather than recalling either.
|
| describe_plateA | What is on the print plate: objects, their parts, and any mesh defects. Prefer this over looking at an image — it reports exact names, part structure, and mesh problems that a render cannot show. Read from the last saved project file. |
| get_plate_thumbnailA | A rendered image of the plate, for questions that are genuinely visual. Views: 'plate' (as shown in the UI), 'top' (orthographic top-down), 'flat' (unlit, smallest). Use describe_plate first for anything that can be answered from names, structure, or mesh statistics. |
| rememberA | Keep one fact for future sessions. Everything stored is already in your system prompt, so this is for writing, not reading. Store what will still be true next week: how this printer and its plates behave, what the user wants without being asked, what was tried on a print and how it turned out. Not what you can look up — a preset value, a setting's range — and not what happened this turn.
|
| forgetA | Drop a remembered fact by its key, once it is wrong or spent. |

TDQS
Scored across 14 tools
Most tools are clearly separated by resource and action: preset retrieval/editing, wiki search/read, settings find/describe, and plate describe/render. The only possible confusion is between get_preset and get_current_presets, and between search_wiki and read_wiki, though their descriptions do disambiguate them.
The majority follow a consistent snake_case verb_noun pattern (list_presets, get_preset, set_preset_values, describe_setting, read_wiki). remember, forget, and preflight deviate from that pattern, making the naming mostly but not perfectly consistent.
Fourteen tools is within the ideal 3-15 range and each tool covers a distinct facet: memory, presets, settings lookup, plate inspection, and wiki reference. The size feels appropriate for an OrcaSlicer copilot rather than padded or insufficient.
The set has significant gaps: descriptions explicitly defer to absent tools such as get_selection, measure_slice, and suggest_settings, so agents will hit dead ends when trying to identify the current plate/object, measure geometry, or get recommended settings. There is also no tool to delete a cloned/edited preset, leaving the preset lifecycle incomplete.
