Context stays coherent
If Manny separately chats with the copywriter, designer, and funnel builder, each one ends up with a partial version of the truth. The manager keeps one current brief and passes the right slice to each worker.
Agent architecture recommendation
Direct specialist access feels like more control. At scale, it usually creates more context drift, more coordination work, and weaker accountability.
The human should manage the outcome, not the org chart. A Marketing Manager agent keeps the business goal, campaign strategy, brand standards, constraints, and current state in one coherent place. Then it calls specialist sub-agents as tools to get the work done.
If Manny separately chats with the copywriter, designer, and funnel builder, each one ends up with a partial version of the truth. The manager keeps one current brief and passes the right slice to each worker.
Direct access makes Manny responsible for remembering who knows what, which version is current, and whether the copy still matches the funnel. That is exactly the work the agent system should absorb.
A manager can run research, copy, design, funnel structure, and QA at the same time. If the human controls every specialist thread manually, the human becomes the bottleneck.
When the funnel underperforms, the answer should not be "which sub-agent did it?" The Marketing Manager owns the output and uses specialists to improve it.
A copywriter may write stronger copy that hurts the funnel. A designer may make the page prettier but less direct. The manager balances tradeoffs against the business objective.
If every specialist becomes a Telegram contact, the interface turns into noise: more threads, repeated explanations, and harder retrieval. A few high-level agents keep the system manageable.
The manager can remember what was tried, what was rejected, what the brand voice is, and what the current launch goal is. Sub-agents can remain task-specific and disposable.
Control should live in the brief, standards, constraints, approval gates, and final review. Manny can still ask for the copywriter's reasoning or three variants without making that copywriter a permanent chat relationship.
Direct sub-agent access can exist, but it should be an exception, not the default. A good compromise is "workshop mode": Manny can talk directly to the copywriter for a short, intentional session, then the Marketing Manager ingests that transcript and resumes ownership of the campaign.
This preserves the feeling of control without turning every specialist into a permanent coordination burden.
