SDK Overview

• Project: simplecadapi
• Version: 2.0.2
• Package distribution: simplecadapi==2.0.2

What this skill bundles

• Skill instructions (SKILL.md)
• Documentation references (references/docs/)
• Generated core API docs (references/docs/api/) and standard-library docs (references/docs/stdlib/)
• High-level SDK summaries (references/*.md)

What this skill does not bundle

• SDK source code (src/simplecadapi) is intentionally excluded.
• Environment/bootstrap workflows are intentionally not the focus here.
• Self-evolving or skill-local case packaging is intentionally excluded.

Main SDK surfaces

• Geometry and modeling operations in docs/api/.
• Standard parts library in docs/stdlib/, including scad.std.gear, scad.std.bearing, scad.std.chain, and scad.std.fastener factories.
• Core shape/type semantics in docs/core/.
• Graph/model serialization and replay APIs.
• Expression, parameter, and semantic reference types.
• Source-preserving tagging with apply_tag(...), apply_tag_rselection(...), scoped list_tags(...)/explain_tag(...), and scoped QL tag predicates.
• Kernel-proven primitive and feature output roles with strict role-based output tag assignment for box, cylinder, extrude, revolve, fillet, chamfer, shell, loft, sweep, and twisted sweep.
• Serializable QL predicates for output_role, projected source_binding, and projected source_topology evidence.

Preferred replayable workflow

• Record modeling steps inside GraphSession when you need replayable outputs.
• Export session/model payloads with export_session_json() and export_model_json().
• Re-import or replay with import_model_json() and replay_model_json().
