# crates.io command packages

crates.io packages with local package pages and command-line or developer workflow metadata.

- **Packages:** 260
- **Protected tools:** 0
- **Approval gates:** 0
- **Non-low risk:** 0
- **Updated:** 2026-08-03

## Why this package group is here

crates.io command packages currently includes 260 package catalog entries. 0 have protected-tool coverage, 0 have approval-gate metadata, and 0 have non-low Geiger classifier findings. The grouping comes from package metadata, so it can stay current as that metadata changes.

## Generated source

This hub uses the same local package data as individual package pages: Nucleus package metadata, Homebrew enrichment, Geiger classifier output, secret-handling manifests, and approval-gate seeds where available.

## Review model

Use the hub to find command families that need tighter secret injection, approval gates, or manual review before agents run them.
