Fields

instruction: String

A full instruction document. Directive extraction runs ONCE, at boot, on this operator-authored text; params fold in later at spawn as data and are never re-parsed for directives, so a param value cannot introduce machinery the operator never wrote.

params: BTreeMap<String, ParamSpec>

The ONLY holes the model may fill, schema-validated at spawn.

servers: Option<Vec<String>>

Flat tier only: narrowing grants from the parent’s server/tool set.

tools: Option<Vec<String>>

limits: Option<Value>

Flat tier: the full per-spawn limits object. Instance tier: OS caps only (memory, cpu) — token ceilings live in budget.

mode: Option<String>

model: Option<String>

priority: Option<String>

skills: Option<Value>

context: Option<Value>

output_contract: Option<String>

output_schema: Option<Value>

budget: Option<Value>

Instance tier only: the child’s own budget (a Budget document), enforced in-child with on_exhausted: refuse.

ttl: Option<Dur>

Instance tier only: a lifetime after which the child retires gracefully rather than being killed.

until: Option<String>

A signal name (templated over params) whose delivery IN THE CHILD retires it.

singleton: bool

One live child at a time; its A2A peer alias is the template name.

durable: Option<bool>

Durability class: false ⇒ the spawn’s record is memory-only (and an instance child runs on a memory store — no restore-respawn). Absent ⇒ the deployment default (store.durability.work).

result: Option<Value>

Instance tier, mode: sync: {workflow: <name>} — the spawn resolves when the CHILD’s named workflow first completes, returning that run’s output. Composed as a reporter workflow in the child; requires the parent to have an A2A listener.

mirror_streams: Option<Vec<String>>

Instance tier: child streams mirrored into the PARENT’s same-named streams — each event forwarded over the socket and appended with source instance:<handle>. Requires the stream declared on BOTH sides and a parent A2A listener.
