STL CLI

Command-line interface for STL operations. Validate, convert, analyze, build, query, diff, and clean STL files from the terminal.

Commands

stl validate input.stl — Syntax and semantic validation

stl convert input.stl --to json — Convert to JSON, Turtle, JSON-LD

stl analyze input.stl — Graph analysis report

stl build \"[A]\" \"[B]\" --mod \"confidence=0.9\" — Build statements from CLI

stl query input.stl --where \"confidence__gt=0.8\" — Filter statements

stl diff a.stl b.stl — Semantic diff

stl clean llm_output.txt — Clean LLM output

"pip install stl-parser (includes CLI

MCP Server Tools

"STL tools exposed as MCP (Model Context Protocol

MCP Tools

Validate STL text syntax and semantics

Parse STL text into structured JSON

Graph statistics: nodes, edges, centrality, cycles

Validate STL file by path

Domain Schemas

Six domain-specific validation schemas for constraining STL to specific fields. Each schema defines required anchors, modifiers, and value ranges.
