describe

describe is a command for coding agents from vyuh-labs/dxkit. It costs 0 tokens per session (722 once invoked), scanned A, original, MIT.

A read-only command that creates a shareable map of a repository's functions and, when available, its HTTP interface, such as routes and the calls between them.

In plain words
What is it for?
Use it to review a codebase, export repository details as JSON, or create a self-contained interactive HTML map of its function and HTTP relationships.
Why use it?
It makes the code structure and web-service connections easier to inspect, while labeling what was directly observed versus inferred or unknown.

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

describe 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 4d ago.

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.

How it starts

The opening of the file, as written. The whole thing — 73 lines — stays where its author put it; the contents beside it link to each section on GitHub.

vyuh-dxkit describe

Run as: vyuh-dxkit <cmd> after npm install -g @vyuhlabs/dxkit, or npx @vyuhlabs/dxkit <cmd> for one-shot use. Examples on this page use the short form.

A shareable snapshot of what dxkit sees in a repository: the whole code graph (every function, what it calls, and what calls it), joined to the HTTP contract when one exists (routes served, calls made, and how they bind). It reads the same deterministic analysis the gate uses and adds no new heuristics.

describe is read-only. It prints a terminal summary and writes nothing to your repository unless you pass --out.

Usage

vyuh-dxkit describe [path] [--json] [--html] [--out <file>]

With no flags it prints a terminal summary. Every count it reports is labeled observed / derived / inferred / unknown, so the picture is honest about what was read directly versus resolved.

Flags

Flag Effect
--json Emit the versioned repo card (dxkit.repo-card.v1) to stdout, for tooling
--html Emit a self-contained, interactive contract-map HTML page to stdout
--out <file> Write the output (HTML or JSON) to a file instead of stdout
path Repository to describe (defaults to the current directory)

The contract map

--html produces one self-contained file: no server, no API key, no external assets. Open it in a browser and it renders a live, force-directed map with three views:

View Shows
Full code graph The whole code graph: functions sized by fan-out, with the contract overlaid
Request paths Each route to its handler to the internal functions it fans out to
Seam Every endpoint as a color-coded tile, laid out for a health scan at a glance

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.

describe is a command published in the GitHub repository vyuh-labs/dxkit (10 stars, last pushed 6d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 722 tokens. 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.
