checks

A command for listing and running repository checks configured in .dxkit/policy.json, along with the active built-in lint checks. Lint checks automatically inspect code for rule violations.

In plain words
What is it for?
Use it to review configured checks, perform a dry run, and see whether each check passed, failed, or was skipped.
Why use it?
It shows which checks are active and lets you run them without blocking work or changing the baseline. Existing failures can be distinguished from problems introduced by a new change.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

checks 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 2d 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 — 152 lines — stays where its author put it; the contents beside it link to each section on GitHub.

vyuh-dxkit checks

Run as: vyuh-dxkit <cmd> after npm install -g @vyuhlabs/dxkit, or npx @vyuhlabs/dxkit <cmd> for one-shot use.

List and dry-run the custom checks configured for this repo — user-declared repo invariants (.dxkit/policy.json:checks) plus the pack-declared built-in lint gate.

A custom check is a first-class gate citizen: its failures are fingerprinted, baselined, and gated by guardrail check net-new only — a pre-existing failure is grandfathered, so you can turn on a lint gate against a repo with a thousand existing warnings and only ever block the error this change introduced. User checks and lint share one runner; lint is the first consumer of the seam, not a parallel path.

Usage

vyuh-dxkit checks [list] [path] [--json]   # what's configured (default)
vyuh-dxkit checks run  [path] [--json]     # dry-run: execute each check, no gating
Option Effect
list (default) Show configured user checks + active lint gates, and any skipped entries.
run Execute each check and report pass / fail / skipped-* + finding counts. Never blocks, never writes a baseline.
path Repo root. Defaults to .
--json Machine-readable output (agent-queryable).

checks list resolves through the same entry point the baseline producer and the guardrail use, so what it prints is exactly what the gate sees. checks run answers "what would the gate find right now?" — but net-new-ness is decided by guardrail check against the committed baseline, not here.

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.

checks is a command published in the GitHub repository vyuh-labs/dxkit (10 stars, last pushed 4d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,799 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.
