Public Registry Packs

Gas City publishes first-party reusable packs through the public gascity-packs registry. A registry is a discovery catalog: checked-in pack.toml files still record durable GitHub tree URLs plus an optional version constraint or pin. The public main registry is configured by default, so there is nothing to add. Refresh its catalog before browsing: 
gc pack registry refresh main
Search and inspect entries: 
gc pack registry search gascity
gc pack registry show main:gascity
When you decide to use a pack, prefer the import command printed by gc pack registry show. It writes the durable source URL and selected version; it does not write the local registry handle into pack.toml.

Built-In Packs

Gas City’s built-in packs are explicit imports, not implicit loader magic. New cities created by gc init include pinned imports for the bundled packs they need. gc doctor --fix can repair missing or stale bundled-pack pins. See System Packs for the built-in pack contract.

​
Freshness

Registry records are cached locally. gc pack registry search and gc pack registry show warn when a cache is older than the freshness window. The default window is 24 hours. Use --refresh when you want the command to fetch the latest catalog before reading it: 
gc pack registry search gascity --refresh
gc pack registry show main:gascity --refresh
Set GC_REGISTRY_FRESHNESS to a positive Go duration string when you want a different warning window: 
GC_REGISTRY_FRESHNESS=1h gc pack registry search gascity
Invalid, zero, or negative values warn and are ignored for freshness calculation.

​
Publishing

Use the registry submission command for pack publish requests: 
gc pack registry publish .
The command submits the pack rooted at the given path to the configured registry service. The hosted registry still reviews and lands catalog changes before other users see them; after a publish is accepted, refresh local caches before searching or showing the new entry.
