How to use the atoms directory

One request, every catalog

Everything an agent needs to discover the Convergent Systems atoms ecosystem is at one URL:

curl https://atoms.convergent-systems.co/directory.json

Fields

• status: live (web app deployed, /exports/catalog.json reachable) or bootstrap (schemas + intent declared, no deploy yet).
• atom_types: declared types in ATOMS.yml. For live catalogs this matches the types in the live catalog.json.
• composition_type / composition_dir: where compositions live (prompts, agents, etc).
• runtime_consumers: products / runtimes that pull this catalog at runtime.
• live: present only when the catalog is deployed; contains the live atom / composition / rule counts and a built_at timestamp from the catalog's own export.

Consuming a specific catalog

Each live catalog publishes its full content at <pages_url>/exports/catalog.json. Example:

curl https://prompt-atoms.pages.dev/exports/catalog.json | jq '.atoms[0]'

Caching

The directory is cached for 60s at the edge (Cache-Control: public, max-age=60). CORS is open (Access-Control-Allow-Origin: *) so any client can fetch.

Rebuild cadence

The directory rebuilds on every push to main of convergent-systems-co/atoms. To force a refresh, push a no-op commit or re-run the deploy workflow.
