etetoolkit SKILL.md skillA
etetoolkit from marielynneblock/arcanum-artifex is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add marielynneblock/arcanum-artifex/etetoolkit@git:20260710.0115f49Pins git:20260710.0115f49 in mdr.lock. Pin the fingerprint instead.

Phylogenetic tree toolkit (ETE). Tree manipulation (Newick/NHX), evolutionary event detection, orthology/paralogy, NCBI taxonomy, visualisation (PDF/SVG), for phylogenomics.
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
# ETE Toolkit Skill
## Overview
ETE (Environment for Tree Exploration) is a toolkit for phylogenetic and hierarchical tree analysis. Manipulate trees, analyse evolutionary events, visualise results, and integrate with biological databases for phylogenomic research and clustering analysis.
## Core Capabilities
### 1. Tree Manipulation and Analysis
Load, manipulate, and analyse hierarchical tree structures with support for:
- **Tree I/O**: Read and write Newick, NHX, PhyloXML, and NeXML formats
- **Tree traversal**: Navigate trees using preorder, postorder, or levelorder strategies
- **Topology modification**: Prune, root, collapse nodes, resolve polytomies
- **Distance calculations**: Compute branch lengths and topological distances between nodes
- **Tree comparison**: Calculate Robinson-Foulds distances and identify topological differences
**Common patterns:**
```python
from ete3 import Tree
# Load tree from file
tree = Tree("tree.nw", format=1)
# Basic statistics
print(f"Leaves: {len(tree)}")
print(f"Total nodes: {len(list(tree.traverse()))}")
# Prune to taxa of interest
taxa_to_keep = ["species1", "species2", "species3"]

How to install
mdr add marielynneblock/arcanum-artifex/etetoolkit@sha256:5a485f7048495548The line at the top of this page pins the label git:20260710.0115f49, 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.
