Other apps cannot call the toolkit APIs on your agent; publish your own API

Description

For isolation, Agent, Agent Task Builder, and related toolkit codeunits error when the target instance belongs to another app. There is no supported way to pass another extension's metadata provider into SetInstructions or Create. Partners who need to enqueue work must call a public API you own.

Best Practice

Expose a public codeunit in the agent app (Access = Public) whose procedures take User Security ID and forward to Agent / Agent Task Builder. Document that surface as the integration contract. Keep toolkit calls inside that app.

See sample: cross-app-agent-calls-need-your-public-api.good.al.

Anti Pattern

From app B, calling Agent.SetDisplayName or Agent.Create with app A's metadata provider. Detection signal: toolkit agent APIs used with an Agent Metadata Provider value not declared in the same app.
