slice_with_template

Slice STL or 3MF files using predefined templates from your local registry. Specify printer model, template, and settings to generate ready-to-print 3MF files.

Instructions

Slice an STL or 3MF using a named template from the local registry. This is a higher-level wrapper around slice_stl for template-based workflows.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
stl_pathYesPath to the STL or 3MF file to slice
template_nameYesNamed template from the local registry.
template_dirNoOptional template directory override when resolving template_name.
bambu_modelYesREQUIRED: Bambu Lab printer model. Ask the user if not known. Using the wrong model can damage the printer.
slicer_typeNoType of slicer to use (bambustudio, prusaslicer, cura, slic3r, orcaslicer) (default: bambustudio)
slicer_pathNoPath to the slicer executable (default: value from env)
nozzle_diameterNoNozzle diameter in mm (default: 0.4)
bed_typeNoBed plate type for slicing (default: textured_plate). SuperTack is accepted only for pre-sliced print jobs until the BambuStudio CLI identifier is verified.
use_printer_filamentsNoWhen true, and no explicit slicer profile or load_filaments override is provided, use the printer's current or first loaded AMS filament as the slicer filament profile.
hostNoHostname or IP of the printer (default: value from env)
bambu_serialNoSerial number (default: value from env)
bambu_tokenNoAccess token (default: value from env)
load_filamentsNoOverride filament profiles. Semicolon-separated paths to filament JSON configs.
load_filament_idsNoOptional filament-to-object mapping string.
ensure_on_bedNoLift floating models onto the bed.
arrangeNoAuto-arrange objects on the build plate.
orientNoAuto-orient model for optimal printability.
repetitionsNoNumber of copies to print.
scaleNoUniform scale factor.
rotateNoZ-axis rotation in degrees.
rotate_xNoX-axis rotation in degrees.
rotate_yNoY-axis rotation in degrees.
min_saveNoProduce smaller output 3MF.
skip_modified_gcodesNoIgnore stale custom gcodes in the 3MF.
slice_plateNoWhich plate index to slice. 0 = all plates.
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description must bear full responsibility for behavioral disclosure. The description only mentions it is a wrapper and does not reveal any behavioral traits such as file generation, permission requirements, or side effects.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two concise sentences—one stating the purpose and the other clarifying its nature as a wrapper. Every word adds value with no redundancy.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given 25 parameters and no output schema, the description is minimal. It does not explain the template resolution process or return values, though the sibling tool 'slice_stl' likely shares behavioral context. Adequate but leaves gaps.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the schema already documents each parameter. The description adds minimal extra meaning beyond noting that it uses a 'named template'. Baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb ('Slice') and resource ('STL or 3MF'), and distinguishes itself from the sibling tool 'slice_stl' by noting it is a 'higher-level wrapper' for template-based workflows.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage for template-based workflows by calling it a 'higher-level wrapper around slice_stl for template-based workflows'. However, it does not explicitly state when to use this tool versus alternatives or provide exclusion criteria.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
