The Library Navigation Briefing
Imagine standing in the center of a huge abandoned library: thousands of books scattered on the floor, all index cards lost. Now imagine pressing a button called Graphify — within seconds, books cluster by topic, glowing threads reveal citation relationships, and you hold a single-page 'library navigation briefing'. In Graphify, that briefing is GRAPH_REPORT.md: the highest-density map of landmarks distilled from the noise of ten thousand lines of source code.
God's-Eye View: The Worked Examples Benchmark
The best teacher is the project's built-in worked/ directory. Take worked/karpathy-repos/, a complex mixed corpus of 52 files: hardcore Transformer implementation code, deep papers on neural network evolution, and even architecture screenshots saved by Andrej Karpathy.
A human developer would need at least an afternoon to read these 52 files. Graphify's performance:
1. 71.5x compression ratio — millions of raw tokens compressed into a graph of a few thousand tokens.
2. Community clustering — it identifies 4 core communities: Kernel-Ops, Model-Architecture, Optim-Heuristics, and Data-Pipeline.
The lesson: Graphify's power is not 'reading fast' but 'separating clearly' — turning a flat file list into a multi-dimensional functional map.
The Three-Stroke Reading Method for GRAPH_REPORT.md
After running /graphify, don't open the fancy HTML graph first — open GRAPH_REPORT.md.
Stroke 1: Check the God Nodes
The report's opening usually lists the highest-Degree nodes. These are your system's lifelines:
- If the god node is a
Configclass, your project is configuration-driven with coupling concentrated in initialization. - If it's a
BaseManager, you use a centralized dispatch model. - Navigate code logic like browsing Wikipedia.
- Experience the jelly-like gravity interaction in Obsidian's Graph View locally.
God nodes are the top refactor priority and the first anchor for AI assistants to understand the system.
Stroke 2: Inspect Surprising Connections
The most 'detective-like' section: cross-community links that are topologically distant but semantically similar. *Real case*: in a payment system analysis, Graphify found RefundLogic unexpectedly connected to MarketingBanner — revealing that the marketing team had bypassed interfaces to read refund status directly, a serious security risk.
Stroke 3: Answer the Suggested Questions
The report ends with 4-5 key questions. These test both the AI and the human: by asking them in conversation, you quickly verify graph quality and build absolute control over the project.
Obsidian Vault: Internalizing the Graph as a Second Brain
The --obsidian flag converts the abstract graph into a bi-directionally linked note vault loadable in Obsidian. Every code class, paper, and Rationall intent becomes a Markdown file; content summaries form the body, and Backlinks form the edges.
Dynamic Freshness: watch and update
Code is alive and changes hourly. With graphify watch, the system silently monitors file changes in the background — every Ctrl+S triggers millisecond-level AST re-extraction and local graph redrawing, ensuring the AI's senses are always up to date.
From ten thousand lines of code to one A4-sized report, Graphify performs a great 'cognitive dimensionality reduction': instead of being trapped in a file maze, you stand on topological high ground overlooking the entire city of logic.
