etetoolkit SKILL.md skillA

etetoolkit from k-dense-ai/scientific-agent-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add k-dense-ai/scientific-agent-skills/etetoolkit@v3.0

Pins v3.0 in mdr.lock. Pin the fingerprint instead.

Analyzes, manipulates, compares, annotates, and visualizes phylogenetic or other hierarchical trees with ETE 4. Supports Newick/Nexus tree I/O, topology edits and pattern matching, Robinson-Foulds comparisons, gene-tree evolutionary events and reconciliation, NCBI/GTDB taxonomy, SmartView exploration, and publication rendering. Applies to existing trees after alignment and phylogenetic inference, rather than inferring trees from raw sequences.

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 4

## Scope

Use ETE 4 to work with an existing tree:

- Read Newick/Nexus, then inspect, annotate, transform, root, prune, and write
  Newick trees
- Compare topologies and calculate phylogenetic distances
- Find repeated subtree topologies with `TreePattern`
- Analyze gene trees with `PhyloTree`
- Query local NCBI or GTDB taxonomy databases
- Explore large trees interactively with SmartView
- Render PNG with SmartView or PNG/PDF/SVG with the optional Qt treeview

ETE does not replace sequence alignment or phylogenetic inference software. For
raw sequences, first use MAFFT or another aligner and IQ-TREE 2, FastTree, or
another inference tool; then load the resulting tree into ETE.

## Current Target

This skill targets **ETE 4.4.0**, released September 3, 2025 and verified as the
current PyPI release on September 30, 2026.
Core, phylogeny, local synthetic taxonomy and helper checks target this released
package, not unreleased upstream changes. See
[`references/review.md`](references/review.md) for executed coverage and limitations.

How to install

The exact contents, by fingerprint
mdr add k-dense-ai/scientific-agent-skills/etetoolkit@sha256:da2e57c0e3677a42

The line at the top of this page pins the label v3.0, 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.
