Don't fan out past your review capacity

Shared methods · A shared method; linked tool guides explain the exact steps.

Agents multiply what gets produced; nothing multiplies what you can actually read. The ceiling on useful parallelism is your review throughput.

Quick fix: Don't fan out past your review capacity

Instead of Ten parallel agents, ten branches by lunch, and an afternoon of skimming merge buttons.

Try Run as many parallel agents as you can review today (for most people that is two to five) and queue the rest. Unread output is not throughput; it is inventory.

Why this works

Parallel agents shift the bottleneck rather than removing it: production scales with agent count, review scales with you. Past the ceiling, one of two things happens, and both are worse than going slower. Either work piles up unmerged and goes stale, or review quietly degrades to approval — and repository-mining research found exactly that in the wild: most AI-generated pull requests receive no human review at all, with stated review policies and observed behavior pointing in opposite directions. The fan-out felt like speed; the unreviewed merge is where its cost comes due.

When this applies

The generated-but-unreviewed pile is growing across days, or you notice your "review" of agent output has become scrolling to the approve button.

Template

Before spawning, one honest line:

Today I can properly review [N] pieces of this size. Spawn [N], hold the rest. Any output I will not read gets a critic agent before it gets my approval, not instead of it.

Go deeper

What real review of agent output looks like: reviewing agent code and reviewing Cowork output. The per-item version of this failure is output used unread; this is the same debt at fleet scale. Parallel mechanics without the collision risks: worktrees and parallel work.
