Four independent packages need the same upgrade. Which pattern fits?
Why D is the answer
Parallel agents, each isolated to one package
Independent work suits parallelism, and isolation keeps the changes from colliding.
In detail
- The packages are independent, so the work can run in parallel.
- Isolation keeps each agent to one package.
- Open one pull request per package, so each review stays small.
Use case
An illustrative scenario, not a real incident.
Four packages need one upgrade, and they are independent. Four isolated agents finish faster than one working through them in turn.

Why the other options are wrong
- A. A single pull request that is written by four separate agents
- One pull request is hard to review, and mixes separate work.
- B. One agent in a single session with no isolation at all
- One session with no isolation mixes all four packages.
- C. Sequential steps, each waiting for review of the one before it
- Waiting adds delay for no benefit.
