> 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

Supported file types

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:

Python API

graphify is primarily a CLI/skill tool, but the graph output (graph.json) is standard NetworkX JSON you can load and traverse:

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: comments and docstrings as rationale_for nodes:

# 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 contains the graphify entry. If missing, re-run:

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 for more aggressive INFERRED edge extraction:

/graphify ./src --mode deep

Re-run processes all files instead of only changed files

The SHA256 cache lives in graphify-out/cache/. If it's missing or the output folder was deleted, graphify re-processes everything. This is expected. Subsequent runs use the 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 uses 71x fewer tokens than reading raw files. The first run costs tokens to build the graph. Every subsequent query reads the compact graph instead — savings compound across sessions.
