Containing Agent Failures in Local Loops - How We Used AST Refactoring to

Agent failures triggered 50% of local loops -> CI stability at risk. AST refactoring dynamically patched runtime errors in real-time.

At PraLabs, our production systems continually generate telemetry that reveals counter-intuitive bottlenecks. In this teardown, we analyze the architectural failure modes behind: System Retrospective & Weekly Sync: Containing Agent Failures in Local Loops—How We Used AST Refactoring to Dynamically Patch Runtime Errors.

Core Friction & Resolution: Increased local loop stability by 40%.

Tactical Engineering Implementation: Dynamic patching deployed in <15m.. We instrument our build, container, and test execution harnesses to verify latency stability before code reaches trunk.

Architectural Axiom: Optimize for deterministic failure containment and actionable telemetry over synthetic complexity.
