Registries

The vocabularies below are open-ended. Each is a registry rather than a fixed part of the grammar, so that it can grow without a change to the format. A registry entry is never removed, and never reassigned to another meaning.

An entry is added by a spec revision within a major version. An addition MUST NOT change the meaning of an existing entry.

Error codes

The error code registry is normative. Every condition of static validation and every evaluation fault has one code there, of the form <area>.<condition>.

Capability names

durable-timers, signals, sub-workflows, parallel, large-payloads, queue-by, batching, run-python, run-javascript, agent-nodes, states-profile, schema-overlays, unbounded-iteration, lib-time, lib-store, lib-http, lib-data, lib-llm, lib-text, lib-html, lib-money, lib-rank, lib-workweek, lib-human, lib-url, lib-markup, lib-match, lib-phone.

Connector namespaces

Canonical: http, llm, time, data, store. Reserved: wf. The standard library defines each canonical namespace, and the namespace rules protect them.

Filter package namespaces

Canonical: text, html, money, rank, workweek, human, url, markup, match, phone. The standard library defines each, under the same namespace rules.

run languages

python and javascript, for a run step. Each registered language has a capability name of the form run-<language>, among the capability names above.
