Report the Studio runtime, supported version, profiles location, and honest configuration coverage.

Find machine, process, or filament profiles. Use exact names or paths when importing models.

Copy a saved 3MF into an isolated workspace, or import a model with explicit profiles through Studio.

Inspect objects, volumes, resource IDs, instances, plates, bounds, and revision history.

Search the full versioned FFF configuration catalog; inspect types, units, ranges, defaults and scopes.

Read settings and their origin. Scopes: project, plate, object, volume, height_range, filament.

target selects plate_index (1-based), object_id, volume_id, min_z/max_z, or filament_index (0-based). Use keys to bound the response. Studio-normalized settings are returned by completed slice jobs.

Replace user-declared hardware, filament, calibration and physical observations for this project.

Read bambustudio://print-context for the exact input shape. This records declarations, not verified measurements. It does not edit the 3MF. Observations apply only to this revision; optional job_id must match a succeeded slice.

Return deterministic missing-input questions, context/settings mismatches and sourced rules for selected concerns.

Select concerns from bambustudio://quality-guide. Inputs are user declarations; no physical quality is inferred.

Inspect embedded G-code targets, object layers and feature feeds without running it.

With job_id inspect that exact succeeded revision; otherwise inspect the saved project, including older sliced imports. Unknown firmware branches and mappings remain unknown. Targets do not establish actual temperatures or speeds.

Validate and apply an atomic batch to a new revision. Uses JSON numbers, booleans, enums and arrays.

Percentage strings such as '15%' are allowed only on percent types. A filament-scope change selects one existing filament_index; project-scope vector values must be complete arrays. Never overwrites the source.

Restore a historical or candidate revision as a new head; preserve all previous revisions.

revision is the current head for concurrency protection; restore is the revision to copy.

Measure geometry, sampled thickness, contact and downward-facing overhang regions; save SVG previews.

Coordinates are world millimetres. Thickness is sampled geometry, not mechanical strength. Overhang angle is the downward-face threshold from horizontal in degrees (0..90).

Apply spatial edits atomically to a new revision. Read bambustudio://spatial-edits for exact shapes.

Actions: rotate, paint, modifier_box, remove_modifier, height_range, layer_heights. Paint edits a shared mesh resource, affecting every instance of that resource.

Queue a detached Studio slice. Returns immediately; poll get_job. 0 selects all plates; positive indexes are 1-based.

Read persistent slice or comparison status, log tail, estimates, and output locations.

Cancel a queued or running job and terminate its Studio subprocesses.

Compare unchanged baseline with 1..7 alternatives, each {name, changes} or {name, revision}.

Returns immediately with a persistent comparison job; poll get_job. Numeric constraints: max_time_seconds, max_filament_g. Spatial candidates use revisions made with edit_regions. Reports time/material estimates and tradeoffs; strength/finish remain unverified.

Export to a new filename. Supply a succeeded job_id to export that exact revision with slicing artifacts.

Launch the saved revision in Studio for review. This does not synchronize or replace unsaved GUI state.
