mesh-analysis SKILL.md skillA
mesh-analysis from benchflow-ai/benchflow is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add benchflow-ai/benchflow/mesh-analysis@git:20260609.91a5353Pins git:20260609.91a5353 in mdr.lock. Pin the fingerprint instead.

Analyzes 3D mesh files (STL) to calculate geometric properties (volume, components) and extract attribute data. Use this skill to process noisy 3D scan data and filter debris.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Mesh Analysis
This skill provides the `MeshAnalyzer` tool for robustly processing 3D STL files. It handles Binary STL parsing and connected component analysis.
## When to Use
Use this skill for:
1. **Geometric Analysis**: Calculating volume of complex or noisy meshes.
2. **Noise Filtering**: Isolating the largest connected component from "dirty" scan data.
3. **Attribute Extraction**: Extracting metadata (e.g. material IDs) stored in the STL file attribute bytes.
## Usage
The tool is provided as a Python module in the `scripts/` directory.
### Basic Workflow
```python
import sys
# Add skill path to sys.path
sys.path.append('/root/.claude/skills/mesh-analysis/scripts')
from mesh_tool import MeshAnalyzer
# Initialize with file path
analyzer = MeshAnalyzer('/path/to/your/file.stl')
# Analyze specific components
# Automatically identifies the largest component (main part)
report = analyzer.analyze_largest_component()
volume = report['main_part_volume']
mat_id = report['main_part_material_id']
print(f"Volume: {volume}")
print(f"Material ID: {mat_id}")
```
### Calculating Mass
The tool provides the **Volume** and **Material ID**. To calculate **Mass**:

How to install
mdr add benchflow-ai/benchflow/mesh-analysis@sha256:b0c908a5e74b53e7The line at the top of this page pins the label git:20260609.91a5353, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
