> Skill by [ara.so](https://ara.so) — Daily 2026 Skills collection.

graphify turns any folder of code, docs, papers, or images into a queryable knowledge graph. It runs as an AI coding assistant skill — type `/graphify` in Claude Code, Codex, OpenCode, or OpenClaw to extract structure, relationships, and design rationale from your files into an interactive graph you can navigate and query without re-reading raw files.

## Install

```bash
pip install graphifyy && graphify install

The PyPI package is

graphifyy

; the CLI and skill command remain

graphify

.

Platform-specific install

graphify install                        # Claude Code (default)
graphify install --platform codex       # Codex
graphify install --platform opencode    # OpenCode
graphify install --platform claw        # OpenClaw

Always-on assistant integration (recommended)

Run once per project so your assistant consults the graph before searching files:

graphify claude install      # writes CLAUDE.md section + PreToolUse hook (Claude Code)
graphify codex install       # writes AGENTS.md (Codex)
graphify opencode install    # writes AGENTS.md (OpenCode)
graphify claw install        # writes AGENTS.md (OpenClaw)

Undo with the matching uninstall command:

graphify claude uninstall

Manual install (curl, no pip)

mkdir -p ~/.claude/skills/graphify
curl -fsSL https://raw.githubusercontent.com/safishamsi/graphify/v3/graphify/skill.md \
  > ~/.claude/skills/graphify/SKILL.md

Add to

~/.claude/CLAUDE.md

- **graphify** (`~/.claude/skills/graphify/SKILL.md`) - any input to knowledge graph. Trigger: `/graphify`
When the user types `/graphify`, invoke the Skill tool with `skill: "graphify"` before doing anything else.

Core workflow

1. Build the graph

# In your AI coding assistant
/graphify .                        # current directory
/graphify ./src                    # specific folder
/graphify ./raw --mode deep        # aggressive INFERRED edge extraction
/graphify ./raw --no-viz           # skip HTML, produce report + JSON only

2. Outputs

graphify-out/
├── graph.html       # interactive — click nodes, search, filter by community
├── GRAPH_REPORT.md  # god nodes, surprising connections, suggested questions
├── graph.json       # persistent graph — query later without re-reading files
└── cache/           # SHA256 cache — re-runs only process changed files

3. Query the graph

/graphify query "what connects attention to the optimizer?"
/graphify query "what connects attention to the optimizer?" --dfs        # trace a path
/graphify query "what connects attention to the optimizer?" --budget 1500  # cap tokens
/graphify path "DigestAuth" "Response"      # shortest path between two nodes
/graphify explain "SwinTransformer"         # expand a single node

How it works

graphify runs in two passes:

1. AST pass (deterministic, no LLM): Extracts classes, functions, imports, call graphs, docstrings, and rationale comments from code files.
2. Semantic pass (parallel Claude subagents): Extracts concepts, relationships, and design rationale from docs, papers, and images.

Results are merged into a NetworkX graph, clustered with Leiden community detection (topology-based — no embeddings or vector database), and exported as HTML, JSON, and a plain-language audit report.

Edge provenance tags

Every relationship is tagged so you always know what was found vs guessed:

EXTRACTED

INFERRED

AMBIGUOUS

Python API

graphify is primarily a CLI/skill tool, but the graph output (

graph.json

import json
import networkx as nx

# Load the persistent graph
with open("graphify-out/graph.json") as f:
    data = json.load(f)

G = nx.node_link_graph(data)

# Find god nodes (highest degree)
god_nodes = sorted(G.degree(), key=lambda x: x[1], reverse=True)[:10]
for node, degree in god_nodes:
    print(f"{node}: {degree} connections")

# Find all EXTRACTED edges (high confidence, found in source)
extracted_edges = [
    (u, v, d) for u, v, d in G.edges(data=True)
    if d.get("provenance") == "EXTRACTED"
]

# Find INFERRED edges above a confidence threshold
high_confidence_inferred = [
    (u, v, d) for u, v, d in G.edges(data=True)
    if d.get("provenance") == "INFERRED" and d.get("confidence_score", 0) > 0.85
]

# Shortest path between two concepts
try:
    path = nx.shortest_path(G, source="DigestAuth", target="Response")
    print(" -> ".join(path))
except nx.NetworkXNoPath:
    print("No path found")

# Get all nodes in a community
communities = {}
for node, data in G.nodes(data=True):
    community_id = data.get("community")
    if community_id is not None:
        communities.setdefault(community_id, []).append(node)

for cid, members in sorted(communities.items()):
    print(f"Community {cid}: {', '.join(members[:5])}{'...' if len(members) > 5 else ''}")

Working with rationale nodes

graphify extracts

# NOTE:

# IMPORTANT:

# HACK:

# WHY:

rationale_for

# Find all rationale nodes and what they explain
rationale_nodes = [
    (node, data) for node, data in G.nodes(data=True)
    if data.get("node_type") == "rationale_for"
]

for node, data in rationale_nodes:
    print(f"Rationale: {data.get('label')}")
    # Find what this rationale is connected to
    neighbors = list(G.neighbors(node))
    print(f"  Explains: {neighbors}")

Querying semantic similarity edges

# Find cross-file semantic links (concepts connected without structural relationship)
semantic_edges = [
    (u, v, d) for u, v, d in G.edges(data=True)
    if d.get("relation") == "semantically_similar_to"
]

for u, v, data in semantic_edges:
    score = data.get("confidence_score", 0)
    print(f"{u} ~ {v} (confidence: {score:.2f})")

Common patterns

Pattern 1: Onboard to an unfamiliar codebase

# Install graphify, build the graph, read the report
pip install graphifyy && graphify install

# In Claude Code
/graphify .

# Read the output — god nodes tell you what everything routes through
cat graphify-out/GRAPH_REPORT.md

Pattern 2: Mixed research corpus (Karpathy-style

/raw

folder)

Drop code, PDFs, screenshots, and notes in one folder:

raw/
├── attention_is_all_you_need.pdf
├── training_notes.md
├── whiteboard_photo.png
├── nanoGPT/
│   └── model.py
└── tweet_screenshot.jpg

/graphify ./raw

graphify uses Claude vision on images, citation mining on PDFs, AST on code, and semantic extraction on markdown — all merged into one graph.

Pattern 3: Incremental updates (large codebase)

# First full build
/graphify ./src

# After making changes — only re-processes changed files via SHA256 cache
/graphify ./src --update

# After a major refactor — rerun clustering without re-extracting
/graphify ./src --cluster-only

Pattern 4: Live development with auto-sync

# Terminal 1: keep graph in sync as you code
/graphify ./src --watch

# Terminal 2: your normal development
# Code saves → instant AST rebuild
# Doc/image saves → graphify notifies you to run --update for LLM re-pass

Pattern 5: Export to external tools

# Neo4j (generate Cypher, then push)
/graphify ./src --neo4j
# cypher.txt is written to graphify-out/
/graphify ./src --neo4j-push bolt://localhost:7687

# Gephi / yEd
/graphify ./src --graphml

# Obsidian vault
/graphify ./src --obsidian

# Agent-crawlable wiki
/graphify ./src --wiki
# graphify-out/wiki/index.md is the entry point

Pattern 6: Git hook integration

# Auto-rebuild graph on every commit and branch switch
graphify hook install

# Verify hooks are active
graphify hook status

Pattern 7: MCP server

# Start an MCP stdio server so any MCP-compatible client can query the graph
/graphify ./src --mcp

Understanding GRAPH_REPORT.md

The report has four sections:

## God Nodes
Highest-degree concepts — what everything connects through.
These are your architectural load-bearing walls.

## Surprising Connections
Cross-domain edges ranked by composite score.
Code-paper edges rank higher than code-code.
Each result includes a plain-English why.

## Suggested Questions
4-5 questions the graph is uniquely positioned to answer.
Start here when exploring an unfamiliar corpus.

## Token Benchmark
Printed after every run.
First run: extracts and builds (costs tokens).
Subsequent queries: read compact graph.json instead of raw files.
SHA256 cache means re-runs only re-process changed files.

Troubleshooting

graphify: command not found

after pip install

# Check your PATH includes pip's script directory
python -m graphify install

# Or use the full path
python -m pip show graphifyy | grep Location
# then add {Location}/../Scripts to PATH (Windows) or {Location}/../bin (Unix)

Skill not triggering in Claude Code

Verify install wrote the skill file:

ls ~/.claude/skills/graphify/SKILL.md

Check

~/.claude/CLAUDE.md

graphify install

LLM extraction fails / no semantic edges

Parallel subagents require the AI assistant to support multi-agent mode:

• Codex: add

  multi_agent = true

  under

  [features]

  in

  ~/.codex/config.toml

• OpenClaw: uses sequential extraction (parallel agent support is early-stage)
• Claude Code / OpenCode: parallel extraction works by default

Graph has no god nodes or surprising connections

The corpus may be too small (< ~6 files). At small scale, graphify still works but token reduction is minimal — the value is structural clarity, not compression. Try

--mode deep

/graphify ./src --mode deep

Re-run processes all files instead of only changed files

The SHA256 cache lives in

graphify-out/cache/

ls graphify-out/cache/    # verify cache exists after first run

Neo4j push fails

# Verify Neo4j is running and bolt port is accessible
/graphify ./src --neo4j                          # generate cypher.txt first
# then manually import in Neo4j Browser:
# :source graphify-out/cypher.txt

# Or push directly (requires neo4j Python driver)
pip install neo4j
/graphify ./src --neo4j-push bolt://localhost:7687

Set credentials via environment variables — do not hardcode:

export NEO4J_USERNAME=neo4j
export NEO4J_PASSWORD=your_password

--watch

misses doc/image changes

Watch mode gives instant rebuilds for code files (AST only, no LLM). For docs and images, it prints a notification because LLM re-extraction is non-trivial to run on every save. When you see the notification:

/graphify ./src --update    # re-processes only changed docs/images

Token efficiency

graphify prints a benchmark after every run. Typical results:

Token reduction scales with corpus size. At 52 mixed files, querying

graph.json
