Build model-corrected evolutionary distance matrices and distance trees (NJ, BIONJ, FastME, UPGMA) with Biopython Bio.Phylo plus R ape/phangorn/FastME. Covers why a distance is a model-corrected estimate of substitutions per site that undercounts raw because of multiple/back/parallel hits (saturation); why the matrix discards the per-site information ML keeps; the LogDet/paralinear fix for compositional heterogeneity; the UPGMA molecular-clock trap; and the Bio.Phylo landmine that DistanceCalcu…

Works with any agent that supports SKILL.md skills.

What this skill can do

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'bio-phylo-distance-calculations' ] || [ -L ~/.agents/skills/'bio-phylo-distance-calculations' ]; then echo 'A skill folder named bio-phylo-distance-calculations already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/lilinji/GeneTind-Life-Skills' "$d" && git -C "$d" checkout --quiet '908229c955510a1841b216e8bf58f6b22818d4dc' -- 'skills/bio-phylo-distance-calculations' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/bio-phylo-distance-calculations' ~/.agents/skills/'bio-phylo-distance-calculations' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'bio-phylo-distance-calculations' ~/.claude/skills/'bio-phylo-distance-calculations' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
