Crate rig_compose 

rig-compose

Composable agent kernel for rig (and any rig-shaped tool surface): stateless skills, transport-agnostic tools, registry-driven agents, and a signal-routing coordinator.

Originally extracted from Azrael’s threat-detection kernel, this crate is now domain-neutral and can wrap any tool/agent stack.

Composability rules

1. Skill is stateless. Any skill can be assigned to any Agent.
2. Tool is the only side-effectful interface. Local impls and remote transports (see rig-mcp) share the trait; skills cannot tell them apart.
3. Agent holds a slice of the global registries — it never hard-codes skill or tool names.
4. Workflow composes agents. The CoordinatorAgent is one workflow primitive; specialist routing is another configuration of it.

Modules

agent

Agent — composes a SkillRegistry slice and a scoped ToolRegistry to drive an investigation.

context

InvestigationContext — the runtime object that flows through every super::Skill in an agent step.

coordinator

CoordinatorAgent — routes an investigation to the first registered specialist whose signal tag matches the context.

delegate

Agent delegation primitives.

instructions

Agent persona / instruction set.

registry

ToolRegistry and SkillRegistry — composition surfaces.

skill

Skill — a stateless, composable reasoning unit.

tool

Tool — the only side-effectful interface available to skills and agents.

workflow

Workflow — composes one or more super::Agents into a higher-level orchestration unit (e.g. the Overseer’s block-stream pump, or the Phase-5 coordinator/specialist routing).
