Give Your AI Agent a Channel Adaptation Contract

A channel adaptation contract tells an AI agent what may change when one idea becomes several social posts. It preserves the core facts while allowing the opening, level of explanation, format, and next action to fit each destination.

Without that contract, an agent can produce versions that look different but make incompatible promises. A short X draft might remove an important eligibility condition. An Instagram caption might tell people to follow a link that is not available in that placement. A LinkedIn adaptation might add an impressive-sounding business outcome that nobody measured. These errors emerge during adaptation, so checking only the original brief will miss them.

Which parts of a campaign should stay fixed?

Keep verified product behavior, offer conditions, disclosures, dates, attribution, and the central answer fixed across all versions. Adapt presentation around those facts instead of treating each channel as permission to invent a new claim.

Use an illustrative repair service announcing an online estimate request form. Its fixed facts are simple: customers can submit a description and photographs; the team reviews the request; a confirmed quote may require an inspection. The agent may vary the opening, but it must not turn an estimate request into an instant guaranteed quote.

Use your campaign plan to define the shared objective. Write the invariants in a short list beside the source packet. Make negative boundaries explicit: no guaranteed turnaround, no promise that every repair qualifies, and no claim that a photo replaces professional inspection. Then identify the one reader task each version supports, such as understanding what information to prepare.

The cross-posting guide explains the broader adaptation process. The agent-specific addition is a contract the assistant must report against. Every output should state which invariants it preserved and which destination assumptions still need a human check.

What can the agent change for each destination?

Let the agent change structure, vocabulary, supporting detail, and the call to action within the destination's actual capabilities. Require it to explain any change that could affect what the audience believes or does.

For the repair service, a professional-network post could explain why clear photographs help triage a request. An image-led post could become a short preparation checklist. A compact text post could answer one question about estimates. These are distinct treatments of the same verified service, not simply a long caption cut into smaller pieces.

Specify the audience's starting knowledge. “Existing customers” and “people meeting the business for the first time” need different context. The assistant should not assume that every platform audience recognizes an internal product name. Define unfamiliar terms or replace them with the task they describe.

W3C's writing guidance recommends clear instructions and meaningful link text. Use those principles when adapting next steps. “See options” can be vague; “review what to include in your estimate request” tells the reader why to follow the destination. The final placement still needs checking in the actual platform or composer.

How do you organize an agent adaptation run?

Give the assistant one approved idea, a destination contract for each requested version, and a review gate before any draft is saved. Ask for a comparison of meaning, not just a collection of captions.

A useful staged instruction is:

Produce three adaptations of this approved explanation. For each, identify the reader situation, the format, the fixed facts retained, and the proposed next action. Flag any destination behavior you cannot verify. Do not schedule or publish. Stop after presenting the drafts and a list of meaningful differences.

Anthropic's workflow guidance describes prompt chaining as separating a task into checkable stages. Here, the stages are idea interpretation, channel adaptation, meaning comparison, and saving the selected copy. This is an editorial design, not a requirement to build a complicated multi-agent system.

Once selected, text versions can be saved with Caroush's documented create_text_post capability when the connection and scopes allow it. Existing owned image assets can be assembled with create_image_post. Read the current catalog before requesting an operation; the tool name does not imply every channel accepts every media combination.

How do you catch differences that matter?

Compare claims and reader actions across versions before comparing tone. An adaptation fails when it changes eligibility, certainty, attribution, or destination behavior, even if each caption sounds natural by itself.

Ask a reviewer to read only the shortest version and explain what it promises. Then compare that interpretation with the original evidence. Short formats often hide the largest semantic change because omitted words feel like harmless editing. A removed “may,” “eligible,” or “after review” can change the offer substantially.

Review the call to action in its actual location. If a link belongs in a profile or another supported surface, the wording must describe that route accurately. Do not ask the agent to infer link placement from a generic platform name. The caption call-to-action guide provides a useful check: the next step should follow naturally from the question the post answered.

Maintain a small exceptions list. One destination may need a separate disclosure treatment, different visual dimensions, or a manual publishing route. Exceptions are part of the contract, not failures to make every version identical. A reviewed exception is safer than quietly forcing all destinations through the same instruction.

Save destinations as separate decisions

A saved post and a delivery to a connected account are different records. Keep the selected copy, assets, account, timing, and reviewer decision together for each planned delivery. A campaign-level “looks good” should not hide an unreviewed caption variation introduced at scheduling time.

Caroush documents browser approval for scheduling and publication. Direct TikTok publishing through MCP is not supported; use the reviewed Caroush composer for that destination. Plan this branch when creating the adaptation contract so the agent does not promise to finish every destination through the same tool call.

Your social media scheduler can organize approved deliveries after those editorial decisions are complete. It is not the place to discover that one version still needs an asset or an eligibility check. If a destination is blocked, hold that delivery while continuing only the independently approved work.

Make the contract easier to reuse

After the campaign, retain the rules that proved useful and remove instructions that did not influence a real decision. A contract with dozens of vague style adjectives is harder to follow than a short record of fixed claims, audience assumptions, placement requirements, and known exceptions.

Save one accepted and one rejected adaptation for each common situation. Explain why the rejected version failed. For example, “instant quote” is unacceptable because the service provides an estimate request; the problem is factual, not a preference for cautious language.

When the offer changes, update the invariant list before asking for new versions. When a destination changes its format behavior, revisit that destination's contract. This keeps the agent's reusable instructions connected to current reality rather than making a successful past prompt the permanent rule for every future campaign.

Try the contract on one awkward sentence

Choose a sentence containing an important limitation and ask for several channel adaptations of that sentence alone. In the repair-service example, use the inspection requirement. Review whether the limitation survives a compact version, an image headline, and a conversational caption. If the assistant consistently drops it in one format, change the format brief before producing a complete campaign.

Then inspect the surrounding visual. A caption that says an inspection may be required can still sit beneath an image claiming instant pricing. The contract covers the whole publication package, including text embedded in graphics. Record which facts must appear visually and which can be explained in the accompanying caption. That decision should come from the reader's needs and the actual placement.
