Copy-paste-safe. Every command has expected output. If you're building for the community contest, this is where you start.

Publisher identity first
Everything you ship is namespaced under your Ed25519 publisher handle. Bootstrap it once with railcall market publisher init then railcall market publisher register.

What you can ship

Free or paid

Workflows

Signed workflow templates — the airlock-compiled CSVs users install with one command. Free or license-gated.

Signed bundles

Modules

Handler bundles that add new providers or capabilities. Ed25519-signed; set license_required to sell them.

MCP-driven

AI Agents

Claude Skills or custom agents that call your workflows over MCP — governed end-to-end, receipts included.

Quick orientation

shell
# Once, ever
railcall market publisher init
railcall market publisher register
railcall market login

# Every publish
railcall market claim <slug>
railcall market publish

The publish command signs your bundle with the same Ed25519 key that proves your handle. Users install by slug (e.g. sami666/salesforce) and the loader verifies your signature before running a single line.
