AI agents

Plan the agent before you connect it.

ElevenAgents provides voice-agent building blocks, including knowledge, tools, web and telephony deployment, and testing. The work still needs a channel decision, clear boundaries, and a failure plan.

01 / Channel decision

Website or phone?

Choose the channel from the customer task, not from the novelty of a voice interface. A first version can keep one knowledge and action policy while changing how people reach it.

Website agent

Prefer a website when people need self-service answers, links, forms, or a visible next step. The page can show context, validate fields, and offer a human contact route without asking the agent to explain the interface.

Check keyboard access, mobile layout, consent, transcript handling, and what happens when the widget is unavailable.

Phone agent

Prefer phone when the customer is already calling, the task is time-sensitive, or speaking is easier than typing. Keep prompts short and make confirmation explicit before an appointment, transfer, or other consequential action.

Check caller identification, silence and interruption behavior, transfer coverage, recording notices, and an alternative route when the call cannot be completed.

These are implementation decisions, not a claim that one channel performs better in every business. See the official integration overview (opens in a new tab) for the deployment options ElevenLabs documents.

02 / Scope

Knowledge is not an action.

KNOWLEDGE

What the agent can explain

Documents and approved facts give the agent a source for answers. Name the source, owner, update cadence, and topics it must decline or route to a person. Retrieval can ground a response; it does not make an outdated or incomplete source correct.

ElevenLabs documents uploading documents and enabling a knowledge base. Read its knowledge-base guide (opens in a new tab) for the vendor configuration.

ACTIONS

What the agent is allowed to do

An action changes data or triggers a process: look up an order, create a booking, send a message, or transfer a call. Define authentication, required fields, confirmation, idempotency, permissions, timeout behavior, and the message shown when the tool fails.

ElevenLabs documents client, server, and MCP tools. Its tools guide (opens in a new tab) explains the vendor side; your server still owns business rules and secrets.

03 / Integration and handoff

Separate vendor capability from custom work.

ElevenLabs documents

  • Agent configuration, voice, language, and conversation flow.
  • Knowledge bases and tool types.
  • Web, mobile, server, and telephony integration paths.
  • Testing, evaluation, conversation analysis, and analytics.

Your implementation still owns

  • Identity, permissions, API-key storage, and data retention.
  • Business rules, validation, retries, and idempotency.
  • CRM, calendar, ticketing, or other system connections.
  • Human routing, transcript context, monitoring, and rollback.

Handoff is part of the design, not an error message. Define the reason for transfer, the context a person receives, what the customer is told, and what happens outside staffed hours.

04 / Limitations and tests

Test the cases that make a demo fail.

Limitations to plan around

  • Generated answers can be wrong, incomplete, or based on stale sources.
  • Speech recognition, accents, noise, interruptions, and turn-taking can change the input.
  • Tools can time out, return malformed data, or be unavailable.
  • A voice interface does not remove consent, privacy, accessibility, or escalation obligations.

Failure cases to run

  • Ask for an answer that is absent from the knowledge source.
  • Give a missing, ambiguous, or unauthorized action input.
  • Force a tool timeout, duplicate request, or invalid response.
  • Interrupt, go silent, change the subject, or ask for a person.

Browser-local tool

Agent readiness checklist

Mark the decisions and tests your team has covered. The checklist stays in this browser tab; it is not sent to ElevenLabs, Adrythm, analytics, or a server.

Agent readiness items

ElevenLabs has its own testing and evaluation features. This checklist is a local planning aid, not a substitute for running tests in the vendor platform and in your connected systems. See the official agent testing documentation (opens in a new tab).
