Running local agent loops, MCP servers, AST refactoring, headless browser

Agent loops stall due to unresponsive MCP servers -> CI pipelines grind to a halt. Headless browser automation fails to recover.

At PraLabs, our production systems continually generate telemetry that reveals counter-intuitive bottlenecks. In this teardown, we analyze the architectural failure modes behind: Running local agent loops, MCP servers, AST refactoring, headless browser automation (Playwright/CDP), and agent failure containment..

Core Friction & Resolution: Achieved 15% increase in agent uptime.

Tactical Engineering Implementation: Deployable monitoring and retry strategies 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.
