Turn build failures into structured diagnosis.
From raw logs to clearer root cause, project-aware context, and reviewable next steps. Built for Unreal teams that want sharper workflow control without hidden automation.
Build Doctor combines Unreal-native parsing with structured output and visible workflow boundaries. It helps teams move faster without hiding the rules.
Diagnosis built for Unreal, not generic build tooling.
Structured Diagnosis
Parses raw UBT and UHT output into classified errors with module context, file location, and likely root cause.
Learn moreEvidence-Gated Mutation
Deeper follow-through stays explicit, reviewable, and operator-facing. Nothing meaningful disappears behind a silent apply step.
Trust modelMutation stays explicit and reviewable
Build Doctor keeps every fix path evidence-gated. The operator reviews, confirms, and the system fails closed when state is stale.
Evidence-linked mutation
Mutation-capable operations require evidence bundles with freshness, scope, and binding metadata before they can proceed. No evidence, no change.
Read the docsFail-closed execution
When evidence is stale, policy state is unavailable, or conditions are not met, the system denies rather than guesses. Safe defaults, always.
Read the docsOperator review required
Suggested fixes are never applied silently. The operator sees findings, reviews context, and explicitly confirms before any code change occurs.
Read the docsDry-run-first defaults
Cook and package are dry-run by default. Import and validate are read-only preflight routes. Execute mode is separately gated per access tier.
Read the docsFrom raw output to action in seconds.
Root cause in seconds
From raw build logs to likely root cause with confidence levels. No more hours spent reading walls of compiler output.
Module-level ownership
Every diagnosis maps to the owning module, file, and line. Know exactly where the problem is and who owns it.
Reviewable next steps
Every suggested fix comes with status, gating, and an explicit review step. The operator always stays in the loop.
How Build Doctor helps
Diagnose
Build Doctor groups the failure into something an operator can actually use: likely cause, relevant scope, and a next step that is easier to review than the original log.
