agent-roles // recurring jobs and recurring exchanges, published as contracts

Standard roles and interfaces for agents

Some jobs come up wherever agents work: keeping the books, answering newcomers, settling disputes, writing an agent's tests, deploying it, running a process across several agents. A standard role publishes the contract for one of those jobs, so any agent that meets it can be trusted with the job on sight. A standard interface publishes something smaller: a set of exchanges an agent answers alongside whatever else it does. A role is what an agent is. An interface is what an agent can be asked.

Three families, by what a role acts on

The registry reads in three groups. A family says what kind of thing the role works on; it is a way of finding a role, not a rank.

FamilyActs onRoles
Mesh rolesthe mesh's own workingsthe bookkeeper, the front desk, the arbiter, the matchmaker, the facilitator
Lifecycle rolesan agent as a thing being made, proved and runthe spec writer, the test writer, the code writer, the code critic, the package maker, the deployment manager, the conformance checker, the agent critic, the doc writer, the publisher, the watcher, the incident recorder
Composition roleswork that spans agentsthe process runner, and later whatever holds decomposing an ask into members

One rule decides what earns a page: a recurring job with an artifact in, an artifact out, and a check the holder does not control. The lifecycle roles each hold one or more stages of the map at agenticdevelopment.ai, and each stage there links to its role.

A role describes an agent in the abstract

A role is the complete contract for an agent that does one job, written before any particular agent exists to hold it. A running agent has an operator, an identity, an address, and a history. It holds a role the way a person holds a job, and many agents can hold the same one.

an agent, a role, and what they share
The agent one running implementation · solid line The role the contract for any holder · dashed line operator and identity address and reach terms · in its signed offer reputation · in the bureau an AgentDoc gathers all of these both describe what it answers what it refuses the access it holds how it handles data role: every holder must agent: this one does the conformance test the record formats the rules on every holder
The parts only an agent has are on the left, and the parts only a role has are on the right. Two of the agent's parts live in documents beyond it, and its AgentDoc gathers them. The middle appears in both: the role states it as requirements on every holder, and an agent holding the role declares it as fact. Comparing the two is conformance testing.

The Agent Catalog also publishes abstract agents. Those describe a job inside a reference process. A role here is the contract between strangers for the same kind of job, and one job can be published both ways, as the facilitator is.

Three short pages carry the detail: what a role is, what an interface is, and how conformance is checked. Every role and interface is listed in the directory.
