graphify

A guide for using graphify, a local tool that builds a map of code calls from source files. It shows what a function or symbol calls and how two parts of the code connect.

In plain words
What is it for?
Tracing call chains, explaining how symbols connect, and getting oriented in a codebase; it also describes when to fall back to ordinary text search.
Why use it?
It gives a quick, local way to understand unfamiliar code without an online service or language-model API. Its backward impact results are only leads and need confirmation.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

graphify scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

graphify

graphify builds a local, code-only call graph with tree-sitter — no API key, no LLM backend, no token cost. Use it as a forward-orientation aid: given a symbol, see what it calls and how two symbols connect. It is fast and accurate for that.

The one thing to internalize: graphify is strong going forward (explain / path) and unreliable going backward (affected — "what breaks if I change X"). Treat forward queries as trustworthy orientation and reverse queries as a lead to confirm with grep — never as ground truth.

Setup (opt-in — assume it's present)

One-time, human-installed like any host tool: uv tool install graphifyy (or pipx install graphifyy, or pip install graphifyy). This skill assumes it's already there. If graphify isn't on PATH, say so and fall back to grep/Read — don't try to install it yourself.

Build the graph (code-only)

graphify update <dir>

Point <dir> at your source root (e.g. src). This writes <dir>/graphify-out/graph.json. Only ever use update. Never run extract or point it at a semantic/LLM backend, and never pass an API key — code-only keeps it free and local. Rebuild after substantial code changes; the graph is a snapshot.

Use it — forward orientation (the strength)

Pass --graph <dir>/graphify-out/graph.json to each query.

  • graphify explain "<Symbol>" — what this symbol touches: its outgoing calls and immediate neighbors. The go-to "what does this do / what does it reach" query.
  • graphify path "<A>" "<B>" — how two symbols connect, if they do. Good for "does this handler actually reach that writer".

The affected warning (load-bearing)

graphify affected "<Symbol>" claims to list callers ("what depends on this"). It under-reports, and silently — a confident-looking short answer that misses real callers. It does not build caller edges for method calls on a locally-constructed instance (const x = new Foo(); x.method()) or on a closure/parameter receiver (a callback closing over an injected service). So a method that is called can come back "No affected nodes found".

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

graphify is a skill published in the GitHub repository DanielC000/loom (7 stars, last pushed 5d ago), licensed MIT. It adds 75 tokens to every session and 881 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
