Goal: improve the software-release workflow using multi-agent systems without breaking protected slices.

Mechanism reminder for multi-agent systems: Plan roles, pass typed messages/artifacts, gate tools with permissions, converge with a stop condition, and log the whole graph.

Baseline and shock: If three agents each err 5% independently on a serial path, naive end-to-end success can fall near 0.95³≈0.86 before retries.

Tradeoff in play for multi-agent systems: Specialization can raise quality on complex workflows and raises latency, cost, and failure surfaces. Single agents are simpler when tasks are small.

Ship decision: Planner+implementer+tester with max 8 hops and human gate on production deploy; abort loops to on-call.

Rollback triggers for multi-agent systems must cite task success, hops/task, cost/task, loop rate, approval precision. If you cannot name a tolerated regression on the software-release workflow, do not promote the change.

Make it operational

Keep the multi-agent systems decision record beside the software-release workflow code paths that implement it. Future you will not remember why a default exists unless the evidence is linked from the config for multi-agent systems.

Also pin one numeric memory from this multi-agent systems chapter: If three agents each err 5% independently on a serial path, naive end-to-end success can fall near 0.95³≈0.86 before retries. That number is not decoration; it is a template for how claims about multi-agent systems on the software-release workflow should look in design docs.

Common mix-ups

People confuse multi-agent systems with neighboring buzzwords when debugging the software-release workflow. Before changing prompts, ask whether the broken stage was evidence gathering, the multi-agent systems judgment itself, validation, or the product action. Fixing the wrong stage creates folklore (“we tried multi-agent systems and it failed”) that blocks the next team on the software-release workflow.

Rehearsal (multi-agent-systems/worked-trace)

Write a five-line artifact for this page: goal, inputs, check, owner, stop rule. Invent one fluent failure that the check would catch. Keep details specific to multi agent systems rather than generic AI advice.
