Multi Agent Workflow Designer
by ledesixsixsix
Designs a bounded multi-agent workflow: typed handoffs, graph limits, merge authority, failure and resume rules.
I build architecture skills for coding agents that produce system designs you can actually defend. The goal is simple: every module, boundary, and diagram should trace back to a real requirement - not something the model invented to fill a gap. Each skill owns one architectural boundary or task and comes with a clear contract: required inputs, expected outputs, and checks the result must pass before it is accepted. When a constraint is missing, the skill says what is missing and stops. I would rather ship a skill that refuses than an architecture document that looks complete but is wrong. These skills come from a spec-driven workflow I use on real projects, where requirements are clarified and made atomic first, architecture is derived from them, and downstream artifacts keep their trace back to the source. The full SDD pipeline behind them is not public yet. The skills are designed to work independently today and integrate with it later. If your domain is not covered, send a request. Many of these skills started that way.
