# Wire all three agent interfaces on the metadata provider
|
|
|
|
## Description
|
|
|
|
An AL agent type is registered by extending `Agent Metadata Provider`. The platform locates factory, metadata, and task-execution behaviour only through the `Implementation` property on that enum value. Omitting `IAgentFactory`, `IAgentMetadata`, or `IAgentTaskExecution` leaves create, UI identity, or task runs unbound. Models often ship a single codeunit and skip the enum wiring.
|
|
|
|
## Best Practice
|
|
|
|
On the enum value, set `Implementation` for all three interfaces, each pointing at a dedicated codeunit. Keep factory (create, defaults, first-time setup), metadata (setup page, summary, annotations), and task execution (message analysis, intervention suggestions) in separate objects.
|
|
|
|
See sample: [`wire-all-three-agent-interfaces.good.al`](wire-all-three-agent-interfaces.good.al).
|
|
|
|
## Anti Pattern
|
|
|
|
An `Agent Metadata Provider` value with no `Implementation`, only one interface mapped, or all three interfaces pointing at one catch-all codeunit that cannot satisfy the contracts. Detection signal: enumextension of `Agent Metadata Provider` whose value does not list `IAgentFactory`, `IAgentMetadata`, and `IAgentTaskExecution`.
|
|
|
|
See sample: [`wire-all-three-agent-interfaces.bad.al`](wire-all-three-agent-interfaces.bad.al).
