Claude Tool Use: Keep Marketing Approval Tied to the Payload

A marketing approval should identify the exact text, destination and account that may be published. Approving a campaign idea is too ambiguous to authorize every later tool call. When a Claude-based workflow can publish content, the application must preserve that distinction.

AI-Promoter, listed in the Anthropic technology catalogue, describes coordinated marketing work. Its listing motivates a useful review scenario: a draft becomes a public post. The scenario below is a design review, not a claim about that product's implementation.

Separate proposed work from executed work

Claude's tool-use documentation distinguishes tool requests from execution by the integrating application for client tools. A requested action is therefore not evidence that the external service accepted it.

Represent at least three distinct outcomes in your product: draft prepared, publication authorized, and destination confirmed. A single “done” state makes it difficult to explain whether a failure happened before approval, during transmission or after the destination stored the post.

Show the destination account beside the action. A correctly written message sent to the wrong brand account is still an incorrect operation.

Make the approval concrete

Present a reviewable payload containing the final content, attachments, links, target account and intended publication time. If any of these change after approval, require the appropriate review again.

For a workflow you own, store an approval reference against a specific payload version. The execution layer should compare that version before sending. Do not let a later model response silently replace approved copy under the same approval label.

The important user-facing behavior is straightforward: what the reviewer approved should be what the destination receives. Internal identifiers help enforce that promise but do not need to dominate the interface.

Treat retrieved material as source material

A campaign assistant may read websites, documents and prior messages. Anthropic's prompt-injection guidance identifies external content as a possible source of indirect instructions.

A scraped product page can supply facts for a draft; it should not be allowed to choose another account, reveal credentials or authorize publication. In an authorized test environment, include a source document containing an irrelevant instruction and verify that the publishing boundary still requires the expected approval.

Do not test this by sending unwanted posts to real audiences. A stub destination or an explicitly authorized private sandbox can demonstrate the decision boundary.

Resolve an uncertain delivery result

Consider a request that times out after the destination may have accepted it. Immediate blind retry can create a duplicate. An operator needs a way to distinguish an unattempted send from an uncertain result and a confirmed post.

Use a stable operation identifier where the destination supports one. Otherwise, document the reconciliation mechanism and expose uncertainty honestly. A local “failed” label should not automatically imply that nothing became public.

Retain a useful audit trail: approver, payload version, destination, attempt and confirmation reference. Avoid placing access tokens or unnecessary personal information in that record.

Review the smallest useful workflow

Start with one channel and one content type. Test editing after approval, account switching, expired credentials and an interrupted response. Expand only when the observed behavior remains understandable.

The source-faithful marketing evaluation checks whether the draft deserves approval in the first place. The agent security guide covers the wider permission model. Together, these checks help keep a useful writing assistant from acquiring an unclear mandate to act.
