ultra-graph-theory SKILL.md skillA
ultra-graph-theory from 8b-is/smart-tree is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add 8b-is/smart-tree/ultra-graph-theory@git:20261103.bac42c1Pins git:20261103.bac42c1 in mdr.lock. Pin the fingerprint instead.

Model-agnostic Paul Erdős ("Straight from The Book") extremal, probabilistic, and structural graph-theory skill for codebase compression (Szemerédi Regularity), Steiner context pruning, Moser–Tardos LLL parallel worktree scheduling, Erdős–Rényi supply-chain security scanning, and Ramsey clique detection across Gemini, ChatGPT, DeepSeek, and Claude on Antigravity (agy), OpenCode (opencode), Crush (crush), and Claude Code.
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
# Ultra Graph Theory — "Straight from The Book" (`smart-tree` v10.9.0+) > *"Another roof, another proof. In God's Book are the most elegant proofs — and the cleanest architectures."* > — **Paul Erdős (1913–1996), The Magician from Budapest** `ultra-graph-theory` is a **100% model-agnostic and harness-agnostic** architectural intelligence skill powered by `smart-tree` (`st --mode the-book` / `src/mem8/regularity/`). It replaces naive $O(V + E)$ directory dumps with **five rigorous theorems from extremal, probabilistic, and structural graph theory**. --- ## 1. First-Class Citizens: Models & Agent Harnesses This skill treats **all four frontier model families** and **all four terminal/IDE agent harnesses** as first-class citizens without vendor lock-in. ### A. First-Class Frontier Models | Model Family | Optimal `st` Invocation | Context & Reasoning Calibration | | :--- | :--- | :--- | | **Gemini** (`gemini-2.5-pro`, `gemini-3`) | `st -m the-book .` + `ZeroCopyMem8Book::top_k_super_nodes` | Pair Gemini's deep multimodal/long-context window with Szemerédi super-node maps (`K <= 256`) as a global structural index, expanding Erdős Number `0..=2` shells (`max_erdos_radius = 2`). | …

How to install
mdr add 8b-is/smart-tree/ultra-graph-theory@sha256:85281923f95734c0The line at the top of this page pins the label git:20261103.bac42c1, 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.
