Debugging Tools Specification Template

Start with the features that reduce MTTR for your most frequent incident type. Pull data from your incident retrospectives to identify where engineers spend the most time during investigations. If 60% of debugging time is spent searching logs across services, build the cross-service log search first. The [RICE framework](/frameworks/rice-framework) can help you score candidates against each other.

Yes, but with access controls. Most bugs that matter are production bugs. If your debugging tool only works in staging, you are debugging a different system than the one that is broken. Use role-based access, audit logging, and data masking to make production debugging safe.

Index the fields engineers actually filter on (service name, error code, user ID) and leave high-cardinality fields (full request bodies, stack traces) as unindexed but searchable text. Pre-aggregate common queries (error count by service, latency percentiles) so dashboards load fast. Store raw data for ad-hoc queries but accept that those will be slower.

Observability platforms (Datadog, Grafana, New Relic) provide general-purpose monitoring, alerting, and dashboarding. Debugging tools solve specific investigation workflows. The best approach is to build debugging features that pull data from your observability platform rather than duplicating storage. Use the [analytics implementation plan template](/templates/analytics-implementation-plan-template) to structure your data collection.

Integrate it into existing workflows. Link from PagerDuty alerts directly to the relevant trace. Add the tool to the incident response runbook. Build IDE and CLI integrations so engineers do not have to context-switch. The tools with highest adoption are those that appear at the moment of need, not those that require a separate login. ---
