Where should an AI agent's work appear?

Use Slack when several teammates need to see, correct, and approve the work. Use WhatsApp when an owner needs a compact brief and an explicit decision surface. Use Microsoft Teams when the work must stay inside an approved Microsoft 365 environment. None is the universal default.

The right environment puts the source, result, exception, correction, and approval beside the accountable reader. It also has a clear account owner and a retention arrangement that survives the actual engagement as promised.

A role-specific AI agent can replace human brief assembly, routine status reporting, record updates, and follow-through. The person still owns the consequential decision; the environment makes the evidence, correction, approval, and accepted result visible to that owner.

Publisher disclosure: FidelicAI offers Slack, WhatsApp, and Microsoft Teams as work environments. Their feature sets and retention arrangements are different, and third-party platform terms still apply.

Choose the environment from the accountable reader

Slack is the shared-team view

Slack fits work that benefits from several people seeing the same brief, source links, questions, corrections, and approval state. A role can report into an approved channel while the authoritative work product remains in the buyer’s document, project, finance, sales, or content system.

Slack’s app-permissions documentation states that app access follows granted scopes. Slack also distinguishes agents that can make multi-step decisions from ordinary bots, while keeping their possible actions inside app permissions. That is platform behavior, not proof that any particular role has the right job method.

The Slack-specific guide covers channels, scopes, posting rules, and failure modes. Slack history stays after cancellation because it is in the buyer’s Slack.

WhatsApp is the compact owner surface

WhatsApp fits an owner who wants a brief that can be read and decided from a phone. The useful unit is not a stream of model output. It is a short result, the evidence needed for the decision, the unresolved point, and the exact approval requested.

Meta’s WhatsApp Business Platform documentation describes business messaging through a business account and API. The buyer arrangement still has to state the account owner, approved recipients, message rules, record destination, and retention behavior.

Do not choose WhatsApp because it feels immediate. Choose it when one accountable owner can make the required decision there and the durable work record is written to the correct system. FidelicAI does not promise that a fidelic agent can participate normally in every WhatsApp group.

Teams is the governed Microsoft 365 surface

Teams fits organizations that already govern people, apps, files, meetings, and access through Microsoft 365. Microsoft’s Teams admin documentation states that admins can review, allow, block, and assign apps and agents across the organization, specific users, or groups. Exact availability can depend on tenant settings, licenses, and the app’s own configuration.

The Microsoft Teams integration guide covers the current connection. Teams account ownership and channel retention are stated before work begins. Do not promise that Teams history survives cancellation unless that arrangement supports it.

The system of record is usually somewhere else

A work environment is where the team reads and decides. A system of record is where the authoritative state lives. The same product can sometimes be both, but the distinction still matters. The Notion integration guide applies that distinction to a common company record.

FARO may place a prioritized search correction brief in Slack while the source evidence remains in Search Console, Business Profile, site files, and the audit record. SCOUT may request editorial approval in Teams while the approved draft and evidence live in Microsoft 365 or the content system. ALEK may send a compact owner decision through WhatsApp while the decision register lives in Notion or another approved company record.

The current AI agent directory lists the actual connections supported by each role. A logo in an integration directory is not enough. Confirm read access, write access, account owner, plan or edition requirement, revocation, retention, and the acceptance check for the specific operation.

Write five facts before work begins

The cancellation answer states the current FidelicAI boundary. The security page states the architecture and buyer responsibilities. The buyer guide connects the environment decision to the role, assignment, checks, and commercial terms.

Choose the smallest surface that preserves accountability

Use Slack when the job belongs in a shared team channel. Use WhatsApp when one owner needs a compact brief and decision. Use Teams when Microsoft 365 governance is the controlling requirement. Use the buyer’s existing business system directly when another message surface adds no decision value.

Wait when no one owns the account, the result has no authoritative destination, the approval boundary is unclear, or the retention arrangement cannot support the required record.
