Publish Subscribe Designer

publish-subscribe-designer

Purpose

Design publish-subscribe interactions with explicit producers, consumers, events, topics, and failure handling.

Expected inputs

• events to emit
• producers
• consumers
• failure/ordering requirements

Deliverables

• pub/sub design
• topic-event map
• failure handling notes
• operational considerations

Trigger this skill when

• You need to make an enterprise or integration decision that spans more than a single codebase.
• Multiple systems, teams, environments, or governance constraints influence the design.
• A recommendation needs to be tied to enterprise reality rather than generic integration advice.

Operating procedure

1. Clarify the system, estate, or cross-system workflow being assessed.
2. Separate facts, assumptions, constraints, and missing enterprise context.
3. Produce a context-specific analysis rather than a platform- or buzzword-driven recommendation.
4. Make tradeoffs explicit, especially around governance, ownership, runtime failure, and operational cost.
5. Recommend the next most useful architecture or delivery skill.

Quality gates

• Recommendations acknowledge enterprise constraints, ownership, and operational consequences.
• Interfaces, dependencies, and environment implications are not hand-waved away.
• Assumptions and open questions are visible.
• Output is specific enough to inform architecture, integration, or release planning.

Output style

• Be concrete and structured.
• Separate evidence, inference, and recommendation.
• Prefer explicit tradeoffs over single-answer absolutism.
• Use priority or severity where useful.

Failure modes to avoid

• Do not recommend technology because it sounds enterprise-grade.
• Do not ignore team boundaries, operational maturity, or integration sprawl.
• Do not treat all workloads as equally suited to the same platform pattern.
• Do not hide uncertainty behind confident language.
