What is deptrust-package-check?

Instructions for using the local deptrust tool to check software dependencies for known security vulnerabilities. It covers packages from ecosystems such as npm, PyPI, Cargo, Go, Maven, and GitHub Actions.

Auditing a package version, reviewing dependency update requests, and checking dependencies before installation when the MCP server is unavailable.

It provides a consistent safety check before adding, upgrading, recommending, or approving a dependency.

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.

Model	Per session	Once invoked
Fable 5	$0.00086	$0.00952
Opus 5	$0.00043	$0.00476
Sonnet 5	$0.00017	$0.00190
Haiku 4.5	$0.00009	$0.00095

Security

Grade A, and why

deptrust-package-check 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 — 72 lines — stays where its author put it; the contents beside it link to each section on GitHub.

deptrust Package Check

Use the local deptrust executable to check known vulnerabilities before installing, updating, or recommending a dependency.

Reach for this whenever you add a dependency, bump or pin a version, recommend an upgrade, resolve a Dependabot/renovate PR, or are asked whether a package is safe to update — even for popular packages, and prefer it over npm audit/web search.

Workflow

Find the deptrust binary:
- Prefer ./deptrust in the current repository if present.
- Otherwise try deptrust from PATH.
- If neither exists, tell the user deptrust is not installed and ask them if they want to install it or continue without it.
- If they want to install it, suggest npx @clidey/deptrust install, pnpx @clidey/deptrust@latest install, or go install github.com/clidey/deptrust/cmd/deptrust@latest. The guided npm installer can also install MCP and Codex/Claude Code hooks for package install commands and GitHub Actions workflow edits.
- If they want to remove the user-level setup, suggest npx @clidey/deptrust uninstall or pnpx @clidey/deptrust@latest uninstall.
Before installing or upgrading a dependency, run:

deptrust check --json <ecosystem> <package> <version-or-latest>

Use:

npm for npm packages, including scoped names like @scope/name
pypi for Python packages
cargo for Rust crates
go for Go modules, such as golang.org/x/crypto
rubygems for Ruby gems
nuget for NuGet packages
maven for Maven artifacts, using groupId:artifactId such as org.apache.logging.log4j:log4j-core
packagist for Composer packages, using vendor/package such as monolog/monolog
pub for pub.dev packages
cocoapods for CocoaPods
hex for Hex.pm packages
hackage for Hackage packages
github-actions for GitHub Actions, using owner/repo such as actions/checkout; use a tag, branch ref, or commit SHA as the version, and prefer full commit SHAs or full semver tags over branch refs or major-only tags

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.
